Step-by-step explanation:
b =-4 (y-intercept)
x =0
m = 0 (the line doesn't have a slope)
y = mx + c
y = 0(0) + (-4)
y = - 4
(1/3) * (2/8) - (5/12 - 1/4) = 1/12 -2/12 = -1/12
2/3*1=2/3
nine and seven hundred sixty eight
thousandths
F(x) = 4 - x^2
g(x) = 6x
(g - f)(x) = 6x - (4 - x^2)
(g - f)(3) = 6(3) - (4 - 3^2) = 6(3) - 4 + 3^2
Answer:
1/2 or 0.5
Step-by-step explanation:
M= movie cost
v= video cost
Create two equations with the given information. Solve for one variable in equation one. Use that answer to substitute into equation two.
2m+12v=$44
5m+3v=$29
Solve for one variable in equation 1:
2m+12v=44
Subtract 12v from both sides
2m=44-12v
Divide both sides by 2
m=(44-12v)/2
Substitute m answer in equation two:
5m+3v=$29
5((44-12v)/2)+3v=29
(220-60v)/2+3v=29
Multiply everything by 2 to eliminate the fraction
(2)(220-60v)/2+(2)(3v)=(2)(29)
220-60v+6v=58
220-54v=58
Subtract both sides by 220
-54v= -162
Divide both sides by -54
v= $3.00 cost per video
Substitute v value to find m value:
2m+12v=$44
2m+12(3.00)=44
2m+36=44
Subtract both sides by 36
2m=8
Divide both sides by 2
m=$4.00 cost per movie
Check:
5m+3v=$29
5(4.00)+3(3.00)=29
20.00+9.00=29
29=29
Hope this helps! Please mark me as brainliest if it does. :)
