1. Write an equation of the line with a slope of and a y-intercept of -8.
14. Graph
y>-1/2x-4
Y
Answer:
Step-by-step explanation:
both of those equations that are in the system are lines
first line it has a y-intercept at (0, -4) and a slope -1/2 so you can use that to
find another point ( 2 ,-5)
Since the equation has ≥ DRAW a solid line trough points (0, -4) and (2,-5)
Now highligt above the line since (0,0) cheks for the equation
second line goes troughh the points (0,1) because of y-intercept and point (1,2) because the slope is m=1
draw a solid line trough those points and highlight under the line
the intersection of the 2 highlighted ares is your solution
The Hydro water department has a monthly service charge of $12.90 and a volume charge of $1.67 for every 100 cubic feet of water. The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have: total monthly cost = volume charge + service charge y = 1.67x + 12.90 If the Johnson family used 200 ft3 more water this month than last month, then they can expect
Answer:
y = $346.90
Step-by-step explanation:
Given:
y = 1.67x + 12.90
Where,
y = total monthly cost,
x = month. If we let x represent the number of cubic feet of water (in hundreds)
If the Johnson family used 200 ft3 more water this month than last month, then they can expect
x = 200 ft³
y = 1.67x + 12.90
y = 1.67(200) + 12.90
= 334 + 12.90
= 346.90
y = $346.90

Step-by-step explanation:
In order to find the answer you need to use the formula for slope and solve, simplifying if needed.
[tex]Slope=\frac{y^2-y^1}{x^2-x^1}[/tex]
[tex](y^2,y^1)=(-2,4)[/tex]
[tex](x^2,x^1)=(0,3)[/tex]
Substitute:
[tex]\frac{-2-4}{0-3}[/tex]
Solve:
[tex]-2-4=-2+-4=-6[/tex]
[tex]0-3=-3[/tex]
[tex]=\frac{-6}{-3}[/tex]
Simplify:
[tex]-6\div3=-2[/tex]
[tex]-3\div3=-1[/tex]
[tex]=\frac{-2}{-1}[/tex]
[tex]\frac{-2}{-1} =-2[/tex]
[tex]=-2[/tex]

Answer:
For the chart, the missing number on top is 10. the bottom numbers are 1.5 then 9.
For the question, all of the numbers equal the ration 5:3.
Question 2: Yes. 30/x=2/4 which equals 60 (minutes) which is an hour.
Step-by-step explanation:
1A:
2.5 amount of water - 1.5 amount of pasta
10 amount water - 6 amount pasta
15 amount water - 9 amount pasta
2.5 : 1.5
5 : 3
10 : 6
15 : 9
1B. these quantities are proportional because they can all be simplified to the same unit rate of 5 : 3.
2. Johnny is correct. The rate is 4 : 2, with a unit rate of 2 : 1. If you multiply both sides by 30 (how many inches deep the hot tub is) you get a ratio of 60 : 30, meaning it would take an hour to fill up the tub.
Jordan drove for 6 hours at 55 miles per hour, while Matt drove for 3 hours at 60 miles per hour. If Isaac drove 82 miles longer than Jordan and Matt drove combined, for how many miles did Isaac drive.
Answer:
592 miles
Step-by-step explanation:
Answer:
592 miles
Step-by-step explanation:
1. To figure out how many miles Jordan drove, multiply 6 by 55. 6 x 55 = 330.
2. To figure out how many miles Matt drove, multiply 3 by 60. 3 x 60 = 180.
3. Add 330 and 180 together to find out how many miles they drove in total. 330 + 180 = 510 miles.
4. Add Isaac's 82 miles to 510 miles to get the answer of 592 miles.
You and your friend walk to school together every day. You meet at the halfway point between your houses first and then walk to school. Each unit in the coordinate plane corresponds to 50 yards. A) What are the coordinates of the midpoint of the line segment joining the two houses? B) What is the distance that the two of you walk together?
Please show the steps
Answer:
no se
Step-by-step explanation:
The coordinate of the midpoint joining the two houses, since each unit on the coordinate is 50 units is (150, 250) and the distance walked to school is 254.95 yards
From the graph given :
The x - coordinate of the midpoint is 3 units from the origin = (3 × 50) = 150 yards
The y-coordinate of the midpoint is 5 units from the origin = (5 × 50) = 250 yards
Hence, the coordinate of the midpoint is (150, 250)
The distance walked to school :
Distance = √(y2 - y1)² + (x2 - x1)²
Distance = √(400 - 150)² + (300 - 250)²
Distance = √250² + 50²
Distance = 254.95 yards
Therefore, the distance the boys walk to school is 254.95 yards.

A triangle has side lengths of 24, 32, and 42. Is it a right triangle?
Answer:
no its not a right triangle.
The isosceles triangle has two sides with the same length. The base is one-half the length of a side. The expression which represents the perimeter, the distance around the triangle, is s + s + one-half s. What is the value of this expression if s = 8?
A triangle with 2 sides with length s.
Answer:
20 units
Step-by-step explanation:
s = 8
Perimeter = s + s + [tex]\frac{1}{2}*s[/tex]
[tex]= 8 + 8 + \frac{1}{2}*8[/tex]
= 8 + 8 + 4

The diameter of the solar system is about 300,000,000,000,000 kilometers,
which can be written as 3 x 100 kilometers. What is n?
Answer:
D. 14.
Step-by-step explanation:
As we know, 10 to the second power is 100, to the third power is 1000, and so on. These powers add a zero to the number. Since PEMDAS tells us to do exponents before multiplication, we need to find what power of 10 gives us 100,000,000,000,000. Let's count all the zeros. There are 14 zeroes. This means our answer is D. 14. Let's check, though. 10 to the 14th power is 100,000,000,000,000, and that times 3 is 300,000,000,000,000. That means our answer is correct, it is in fact, D. I hope this helps!
Edit: I changed the answer from 13 to 14 because I realized that 13 is incorrect.
