Graph the line with slope
3/4
passing through the point (-4,-1)
.
Answers
Answer: See attached.
Step-by-step explanation:
First, we will create an equation with the slope given.
y = [tex]\frac{3}{4}[/tex]x + b
Then, we will substitute this value in and solve for b (our y-intercept). Then we will graph the equation.
y = [tex]\frac{3}{4}[/tex]x + b
(-1) = [tex]\frac{3}{4}[/tex](-4) + b
-1 = -3 + b
b = 2
Our final equation:
y = [tex]\frac{3}{4}[/tex]x + 2
See attached for the graph. We will plot the point (0, 2) for our y-intercept and then move 3 units up for every four units right, according to the slope.

I've been struggling a lot with interpreting what this problem wants me to find.
The plane departs an airport at 9:00 AM and flies 200 mph southwest. A second plane ldeparts the same airport at 9:30 AM and flies 320 mph northwest. Find the bearing of the second plane from the first one at 10:00 AM.
The reason: I've heard some people say a bearing has to be in one direction (north). I've also heard that a bearing has to be an acute angle and some insist there is an answer to this greater than 90º.
I drew out a diagram with a right triangle, legs of 200 and 160 (320 ÷ 2 for the half hour), separated my right triangle into two triangles with 45º angles, and went from there.
Where the hypotenuse and the 160 side meet, the angle is 51.34º. The 200 side makes a 38.66º angle (both came from arctan). I know for a fact there is an 83.66º angle that can be found.
Trouble is, I'm not sure if that's the actual bearing or not. Everything SEEMS correct there, but I've just heard so many other answers on this that I'm not sure who or what to believe!
Figured I'd see what everyone else thought. It's the "second from the first" that I'm struggling with semantically too. I can do the math just fine here.
Answers
Answer:
6.34°
Step-by-step explanation:
You want to know the bearing of a second plane from the first at 10 a.m. when the first leaves at 9 a.m. and flies 200 mph SW, while the second leaves at 9:30 a.m. and flies 320 mph NW.
LocationsThe first plane flies for an hour at 200 mph, so is 200 miles from the airport on a bearing of 180° + 45° west of south, or 225°.
The second plane flies for half an hour at 320 mph, so is 160 miles from the airport on a bearing of 360° -45° west of north, or 315°.
DirectionThe vector in the direction of the second plane from the first is found by subtracting the location of the first plane from the second:
vector of interest = (160∠315°) -(200∠225°)
A suitable calculator can tell you the difference is ...
vector of interest = 256∠6.34°
The second plane is on a bearing of 6.34° from the first.
__
Additional comment
You are correct that an angle of 83.66° is involved. That would be the measure of the direction vector counterclockwise from the +x axis. You want the bearing angle, measured clockwise from the +y axis (North), so the angle you're looking for is 90° -83.66° = 6.34°.
If you work enough of these problems, you will find that it doesn't matter how you measure the angles, as long as you do it consistently. The second attachment shows the arithmetic using distance∠bearing. The effect is to swap the x, and y coordinates so that they are (N, E) coordinates, rather than the usual (E, N) coordinates. This doesn't have to be confusing. A diagram usually helps.

Solve using the elimination method, and also determine whether a system is consistent or inconsistent, and whether the equations are dependent or independent.
Please helppp <3
Answers
To solve using the elimination method, we need to eliminate one of the variables.
Multiplying the first equation by 3, we get:
9x = 165 - 21y
Now we can write the system as:
9x = 169 - 22y
9x = 165 - 21y
Subtracting the second equation from the first, we get:
0 = 4 - y
Solving for y, we get:
y = 4
Substituting y = 4 in the first equation, we get:
3x = 55 - 7(4)
3x = 27
x = 9
Therefore, the solution to the system is (x, y) = (9, 4).
The system is consistent and independent, since it has a unique solution.

if a baseball team has lost 50 matches out of the 120 matches played in total find out their winning percentage
Answers
Answer:
58.3%
Step-by-step explanation:
120-50=70 (wins)
120 is 100% wins
70. ??
We multiply 70 by 100% then divide by 120.
The number of games won by the team can be calculated by subtracting the number of games lost from the total number of games played:
Number of games won = Total number of games played - Number of games lost
Number of games won = 120 - 50
Number of games won = 70
Now, we can calculate the winning percentage using the following formula:
Winning percentage = (Number of games won / Total number of games played) x 100%
Plugging in the numbers, we get:
Winning percentage = (70 / 120) x 100%
Winning percentage = 58.33%
Therefore, the winning percentage of the baseball team is 58.33%.
Which of the following functions are vertical translations of f(x)=√x?

B. n(x) = -7+ √x
C. g(x)=√x -4
D. h(x)=3+√x

Answers
Answer:
The function f(x) = √x is the square root function.
A vertical translation of a function is a transformation that shifts the graph of the function up or down without changing its shape.
Option (A) is a vertical translation of f(x) because it shifts the graph of f(x) to the right by 5 and then applies three square root operations. However, it is not a vertical translation that shifts the graph up or down.
Option (B) is a vertical translation of f(x) because it shifts the graph of f(x) down by 7 units.
Option (C) is a vertical translation of f(x) because it shifts the graph of f(x) down by 4 units.
Option (D) is a vertical translation of f(x) because it shifts the graph of f(x) up by 3 units.
Option (E) is not a vertical translation of f(x) because it involves multiplying the input of f(x) by a constant factor of 5.
Therefore, the options that are vertical translations of f(x) are (B), (C), and (D).

If a company uses standard costs to record its inventory in the general ledger, what would the journal entry be for a purchase of direct materials with a favorable price variance?
Answers
The journal entry for the company is Debit - Raw Materials Inventory - Standard Cost, Credit - Accounts Payable - Actual Cost.
When a company uses standard costs to record its inventory in the general ledger, the journal entry for a purchase of direct materials with a favorable price variance would be as follows
Debit - Raw Materials Inventory - Standard Cost
Credit - Accounts Payable - Actual Cost
The debit entry would record the standard cost of the direct materials purchased, and the credit entry would record the actual cost of the direct materials purchased, which is lower than the standard cost due to the favorable price variance.
It's important to note that this journal entry assumes that the company is using a perpetual inventory system, where the inventory account is updated continuously as purchases and sales occur. If the company is using a periodic inventory system, the journal entry would be different and would involve adjusting the cost of goods sold account at the end of the period.

Answers
Actual height = (5/6) x 6 = 5 inches
To find the actual width of the h through the center, we can use the same scale. The width of the h on the scale drawing is 1/3 inches (since the h is symmetric). Therefore, the actual width of the h through the center is:
Actual width = (1/3) x 6 = 2 inches
The actual width of the painting is equal to the actual width of the h plus twice the distance from the left edge of the painting to the left edge of the h. On the scale drawing, the distance from the left edge of the h to the left edge of the drawing is (1/6) inches. Therefore, the actual width of the painting is:
Actual width = 2 + 2 x (1/6) = 2 1/3 inches
To find the actual height of the painting, we need to add twice the distance from the top of the h to the top of the painting, and twice the distance from the bottom of the h to the bottom of the painting. On the scale drawing, the distance from the top of the h to the top of the drawing is (5/6) inches, and the distance from the bottom of the h to the bottom of the drawing is also (5/6) inches. Therefore, the actual height of the painting is:
Actual height = 5 + 2 x (5/6) = 6 2/3 inches

Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{DF}{AC}[/tex] = [tex]\frac{EF}{BC}[/tex] ( substitute values )
[tex]\frac{DF}{9}[/tex] = [tex]\frac{25}{15}[/tex] ( cross- multiply )

DF = 15
Answer:
12
Step-by-step explanation:
1. Use the Pythagorean theorem for triangle ABC
a squared (one side of the triangle) + b squared (another side) = c squared (hypotenuse)
so
c squared - b squared = a squared
225 - 81 = 144 ( Find the square root )
which is 12
since Triangle ABC is the same with Triangle DEF then
DF = 12
