Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStandard Form: Ax + By = C
Step-by-step explanation:
Step 1: Define equation
Slope-Intercept Form: 2 + (1/2)x = y
Step 2: Find Standard Form
Rewrite: y = (1/2)x + 2Subtract 1/2x on both sides: y - 1/2x = 2Factor negative: -(1/2x - y) = 2Divide both sides by -1: 1/2x - y = -2Simplify: 5(x+6)−(5−x)−6x
Answer:
25
Step-by-step explanation:
5(x+6)−(5−x)−6x
Remember PEMDAS
P – Parentheses
E – Exponents
M – Multiplication
/D – Division (whichever comes first from left to right)
A – Addition
/S – Subtraction (whichever comes first from left to right)
First, let's distribute the left side:
5 * x = 5x
5 * 6 = 30
5x + 30
Now, lets distribute the right side
-(5 - x) = -1(5 - x)
-1 * 5 = -5
-1 * -x = x ( - * - = +)
x - 5
Now we have:
5x + 30 + x - 5 - 6x
Let's combine like terms.
5x, -6x, and x are like terms. 5x + x = 6x - 6x = 0
30 and -5 are like terms. 30 - 5 = 25
25
Since we can't simplify this any further, that is our answer.

Lntegers 0, -2, -3, -4, -5, -6, -7, -8, and -10 to fill in a 3 x 3 magic square so that every row, column, and diagonal has the same sum. The sum must be -15.
The given numbers are 0, -2, -3, -4, -5, -6, -7, -8, and -10.
Sum of all the integers is -45.
There are 9 places in 3x3 magic square, so divide -45 by 9, we have -45/9=-5.
Put the number -5 at the center place in the magic square.
Now, take the integer having the largest magnitude, i.e -10.
There are two positions to place -10, one is diagonal positions and the other is non-diagonal positions and to make sum = -15, the other number with -5 and -10 must be 0 as shown in the figure (i) and (ii).
Now, the row and column having 0 must have -8 and -7 to make sum -15, which disregards the possibility of -10 at the diagonal place ( figure (i)). So, proceeds with the places in figure (ii), the possible places of -8 and -7 have been shown in figure (iii).
Now, as the sum of diagonals = -15, so place -3 and -2 at diagonal positions and also place the remaining numbers -4 and -6 to make the sum of numbers in columns and rows -15 as shown in figure (iv).

Answer: 1/4 chance of picking red
Step-by-step explanation: There are 120 buttons in all, so the fraction of red marbles is 30/120. 30/120 = 1/4
Hope this helps!
Answer:
30/120
Step-by-step explanation:
Add 30+30+60
120/ 4 because 60/2 is 30 so thats two 30s
then there is a 30 out of 120 chance it is red
how to figure out how many solutions 7y+13=5y-3
Answer:
7y+13=5y-3
7y=5y-16
2y=-16
Y=-8
Step-by-step explanation:
Answer: yes
Step-by-step explanation:
You collect like times together.
7 y + 13 = 5 y - 3
7 y - 5 y = - 3 - 13
2 y = - 16
2 y / 2 = - 16 / 2
y = - 8

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function C equals 34.95 you +6.25 where you is the number of uniforms but if there are at least eight players but no more than 12 players on the team what is the domain you of the function for this situation
Answer:
8 ≤ u ≤ 12
Step-by-step explanation:
Given:
C = 34.95u +6.25
Where,
u = number of uniforms
what is the domain you of the function for this situation
The number of uniforms depend on the number of players
If there are at least 8 players but not more than 12 players on the volleyball team.
u ≥ 8
u ≤ 12
The domain of the function is
8 ≤ u ≤ 12

When it is about 68°F, crickets chirp 124 times a minute. When it is about 80°F, they chirp 172 times a minute. WRITE an equation in POINT SLOPE FORM for the line that models this situation.
Answer:
4x+148
Step-by-step explanation:
Let the temperature be x and time taken by cricket to chirp be y
if when it is about 68°F, crickets chirp 124 times a minute, this means;
at x1 = 68, y1 = 124
If it is about 80°F, they chirp 172 times a minute, then;
at x2 = 80, y2 = 172
The standard form of equation in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line.
First we need to get the slope.
m = y2-y1/x2-x1
m = 172-124/80-68
m = 48/12
m =4
Substitute m = 4 and any point into the expression above. Using the coordinate (68, 124)
get the intercept c
124 = 4(68) + c
c = 272-124
c = 148
The required equation is expressed as y = 4x+148 OR y - 124 = 4(x-68)
x^2 plus 2y divideed by 2x plus 3z equal
Answer:
(x^2 plus 2y")
--------------------
2x(2x + 3)
Step-by-step explanation:
Doing this problem correctly requires the application of "order of operations" rules. "x^2 plus 2y" actually means "(x^2 plus 2y"), and so your
x^2 plus 2y divided by 2x
comes out to:
(x^2 plus 2y")
--------------------
2x
If we now divide this result by "2x plus 3z," we get:
(x^2 plus 2y")
--------------------
2x
================
2x + 3
or:
(x^2 plus 2y")
--------------------
2x(2x + 3)

joyce traveled at an average speed of 60 miles per hour for 4.5 hours and then traveled at an average speed of 35 miles per hour for 1.5 hours. What was the total distance in miles that joyce traveled during this time ?
Answer:
322 1/2 miles
Step-by-step explanation:
Recall how s = d/t ; speed = distance/time.
To effectively solve for distance traveled, rearrange the formula so that distance is on the left-hand side by multiplying speed, and time.
speed × time = distance/time × time
speed × time = distance
distance = speed × time ; d = st.
Now to find the total distance traveled, individually multiply the rate of speed with the time. Time will cancel, and we will get the total mileage.
Given an average speed of 60 mph at a certain time for 4.5 hours, and another average speed of 35 mph at another time of 1.5. Calculate the distance individually, and then add both distances together. Distance 1 = 60 mph × 4.5 h = 60 miles / h × 4.5h = 60 miles × 4.5 = 270 miles.
Distance 2 = 35mph × 1.5h = 35 miles / h × 1.5h = 35 miles × 1.5 = 52 1/2 miles.
Distance 1 + Distance 2 = Total distance.
270 miles + 52 1/2 miles = 322 1/2 miles.
Can you show me how to do it step by step and find what x=?
Answer:
11.2 hours
Step-by-step explanation:
The unknown is the hour time: 120+50.30x=250+38.70x. Now solve it: Subtract 38.70 and 120 from both sides and you get 11.6x=130 x=130/11.6 or 11.2 (about)
So the answer is 11.2 hours. Hope this helps :D
Answer:
So your answer is x = 11.2068965517
or
about, X = 11.21 (to the nearest tenth)
Step-by-step explanation:
50.30x + 120 = 38.70x + 250 (Given)
Move variables to the right and constants to the left by subtracting both sides.
11.6x = 130 (subtraction Property of equaity)
x = 11.2068965517 (Division property of equality)

75% of the items collected at the food drive were cans of soup. If 90 cans of soup were
collected, how many items were collected in all?
Answer:
67.5
Step-by-step explanation:
Answer:
120
Step-by-step explanation:
If 90 cans of soup were collected and it was 75%, take 90/3=30. If 25% of all cans is 30 then when you multiply by 4, to get 100%, you have 120 cans. Also 120/75%= 90
