Answer:
y=-x+8
Step-by-step explanation:
y = mx + b is the basic formula
use the formula y2-y1/x2-x1 to get the slope to get m
-2-5/4-(-3)
-7/7
-1
then use the point slope formula y-y₁=m(x-x₁)
y-5=-1(x-(-3)
y-5=-1x+3
y=-x+8
Answer:
-7/6
Step-by-step explanation:
2x-8x+7=0
combine like terms
6x+7=0
subtract the 7 from both sides
6x=-7
divide 6 from both sides
-7/6 or -1 and 2/3
Let C be the amount of compost
T be the amount of topsoil
Each compost cost = $25
Cost of C compost = 25C
Each topsoil cost = $15
Cost of T topsoil = 15T
Amount of compost + amount of topsoil = 10
C + T = 10 -------> Equation 1
cost of C compost + cost of T topsoil = 180
25C + 15T = 180 --------> equation 2
Solve the first equation for C
C + T = 10
C = 10 - T
Now plug it in second equation
25C + 15T = 180
25 ( 10 - T) +15T = 180
250 - 25T + 15T = 180 (combine like terms)
250 - 10 T = 180 (Subtract 250 on both sides)
-10T = 180 - 250
-10T = -70 ( divide by -10 on both sides)
T = 7
She purchased 7 cubic yards of topsoil .
Answer:
C. 3x + 8
Step-by-step explanation:
A. can be factored; Factor 5 from all terms:
(15x - 10)/5 = 3x - 2
B. can be factored; Factor 4 from all terms:
(4x + 8)/4 = x + 2
D. can be factored; Factor 2 from all terms:
(2x - 2)/2 = x - 1

Product means the result you get after multiplying. So you have to multiply the two numbers. 379*8 = 3032
