X=-2
You can also check by plugging -2 in for x. Here is a picture. Please notify me if I made an error!
Answer:
To be precise, I think it's a pattern question, where you have to add 4 to each number. I'm not very sure though.
Answer:
n(9n)(8n+8) = 72x^3+72x^2
It = 6.888888888 and you can round it to 7
Answer:
x intercept (15/4,0)
y intercept (0,2)
slope 8/15
Step-by-step explanation:
15y − 8x = 30.
To find the x intercept, set y =0
15(0) -8x = 30
8x = 30
Divide each side by 8 to solve for x
8x/8 = 30/8
x = 15/4
To find the y intercept, set x =0
15y -8(0) = 30
15y = 30
Divide each side by 15
15y/15 = 30/15
y =2
To find the slope we solve the equation for y
15y − 8x = 30.
Add 8x to each side
15y − 8x+8x =8x +30.
15y = 8x +30
Divide each side by 15
15y/15 = 8x/15 +30/15
y = 8/15x +2
The slope is 8/15
