Answer:
Step-by-step explanation:
10. 8x+4y=4. y=mx+b
-8x. -8x
4y=-8x+4
÷4. ÷4. ÷4
y = -2x +1
slope = -2. y-int= 1
11. slope is changing y over changing x
m = (y2 -y1)/(x2-x1) (0,-1) x1 = 0, y1=-1
(-4-(-1))/(-2-0) (-2,-4) x2 = -2, y2 = -4
(-4 + 1) / (-2)
-3/-2 = 3/2 answer is 3/2
12. b because negative cause it flip in x axis and it become flatter because of the fraction.
13. 2y =8-8x
÷2. ÷2 ÷2
y = 4 - 4x
Answer A
14. B
Answer:
-15x - 5
Step-by-step explanation:
5x - 15 - 20x + 10
5x - 20x - 15 + 10
-15x - 5
The formula for slope intercept is y = mx + b. the b is the Y-intercept, and the M is the slope. the Y can typically be substituted for whatever equation is being solved.
Answer:
Don't have enough information to answer but
Step-by-step explanation:
you can take the diameter and multiply it by 2 then divide that number by 2. the formula for a cone is V=1/3r^2h so plug the radius into the formula and you should get your answer. Hope that helped! :) -Emaleigh
