Answer:
slope is (-7/4) and y-intercept is 7
Step-by-step explanation:
If we convert the equation 7x + 4y = 28 into Slope-intercept form, we can find the slope and the y-intercept.
7x + 4y - 7x = 28 - 7x
4y = 28 - 7x
divide both sides by 4
y = (28 - 7x)/4
y = 7 - 7x/4
slope is (-7/4) and y-intercept is 7
Answer:
6. a unit rate.
Step-by-step explanation:
Answer:
x = ±8
Step-by-step explanation:
X^2- 64
Set this equal to 0
x^2 -64 =0
Add 64 to each side
x^2-64+64 = 64+64
x^2 = 64
Take the square root on each side
x = ±sqrt(64)
x = ±8
Step-by-step explanation:
Shusil got 8.4 sweets.
Step-by-step explanation:
Gordon share=3/3+5+2×42
3/10×42=12.6
June share=5/3+5+2×42
5/10×42=21
Shusil share=2/3+5+2×42
2/10×42=8.4
Answer:
C
Step-by-step explanation:
First we need to find W. You can do that by dividing 47.25 by 5.25.
47.25 / 5.25 = 9
So W = 9.
Now we do both equations to see which one is correct.
Equation A: 3/4 × 9 = 6 3/4, which is true.
Equation B: 9 - 10.24 = -1.24, which is also true.
Therefore, both equations give you the same solution, C.
