Answer: y = 20x+75
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The cost (y) must be equal to the product of the cost per hour of installation (20) and the number of hours that it takes (x); plus the fixed cost of parts and installation (75).
Mathematically speaking:
y = 20x+75

Answer:
y=14
Step-by-step explanation:
Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.
plug in 25 in 2x and you would get 50°
Since the sum of a triangle is 180° you could set up an equation 
Then, add 50+50=100+10=110
then you would then have 
subtract 110 from 180, leaving you with 70

then divide and you would get 14
Check:
5(14)+10+50+50= 180

.15 of course hhsjdjdjwasting space here dont mind me
Answer:
y(1) = 7
y(2) = 10
y(3) = 13
Step-by-step explanation:
y = 3(1) + 4
y = 3 + 4
y = 7
y = 3(2) + 4
y = 6 + 4
y = 10
y = 3(3) + 4
y = 9 + 4
y = 13
