Answer:

y = -1/4x + 7

Step-by-step explanation:

Plug in the point and slope into y = mx + b, and solve for b:

y = mx + b

8 = -1/4(-4) + b

8 = 1 + b

7 = b

Plug in the slope and b into y = mx + b:

y = mx + b

y = -1/4x + 7

So, the equation of the line is y = -1/4x + 7

Find the value of each missing variable?
LenKa [72]

Step-by-step explanation:

9x - 2 = 5x + 54 because these angles are corresponding

9x - 5x = 54 + 2 add/subtract like terms

4x = 56 and this divided by 4

x = 14

9x - 2 + 10y + 6 = 180° because these two angles makes a straight line

9×14 - 2 + 10y + 6 = 180°

126 - 2 + 10y + 6 = 180° add like terms

130 + 10y = 180° subtract 130 from both sides

10y = 50 divide by 10

y = 10

Duval County Landscaping uses two different sized trucks to deliver mulch. The first truck can transport x cubic yards of mulch,
amm1812
Okay so truck a holds x and truck b holds y. truck a makes 12 trips and truck b makes 14
each time the deliver x or y amount
so say the amount needed at the site is z
truck a has the equation 12x=z
truck b has the equation 14y=z
so 12x=14y and dividing yields 12/14x=y
so that means 6/7x=y
so y can only hold 6/7 of what x can hold.
not sure about expression that represents difference wording. but this should get you off to a good start ;)
