Answer:
b = 
Step-by-step explanation:
Given
y = 
b + 10
Multiply through by 8 to clear the fraction
8y = 5b + 80 ( subtract 80 from both sides )
8y - 80 = 5b ( divide both sides by 5 )
= b

Answer:
No solution
Step-by-step explanation:
The question is 4(3x-5)=12x-24
so we do the step:12x-20=12x-24
No solution.
Answer:
the desired equation is y = -2x + 1
Step-by-step explanation:
As we go from (-2, 5) to (0, 1), x increases by 2 and y decreases by 4. Thus, the slope of this line is m = rise / run = -4 / 2, or m = -2.
Starting with y = mx + b, insert the knowns:
1 = -2(0) + b. Then b = 1, and the desired equation is y = -2x + 1.
It representes the original cost
A=P(1+r)^t
P=present amount
t=time
r=rate
A=final amount
afer 5 years
t=5
A=799(1.03)^5
A=926.26 after 5 years
answer is last option:
<span>799 represents the total value of the painting; the painting will be worth $926 after 5 years
