Answer:
5h+5
5(h+1)
Step-by-step explanation:
Equivalent expressions are the ones that look different but are the same. As the statement says that mason works h number of hours during the 5 day week and 5 hours on the weekend, you can write the following expression:
5h+5
h= number of hours Mason works
Then, you can find the common factor to get an equivalent expression:
5(h+1)
According to this, the equivalent expressions are:
5h+5
5(h+1)

Answer:
14
Step-by-step explanation:
f(-14) = ||-14|| = |14| = 14
Step 1
we need to find the distance between (x, y) and the focus <span>(4,7)
</span>(x, y)-------> is any point on the parabola.
d=√[(x-4)²+(y-7)²]
step 2
Find the distance between (x, y) and the directrix y=8
the distance is given by
d=║(y-8)║
step 3
Equating the two expressions gives
√[(x-4)²+(y-7)²]=║(y-8)║
Squaring both sides give
(x-4)²+(y-7)²=(y-8)²
Expand and simplify
x²-8x+16+y²-14y+49=y²-16y+64
x²-8x+65=-2y+64
Complete
the square Remember to balance the equation
x²-8x+16-16=-2y-1
(x²-8x+16)=-2y-1+16
Rewrite as perfect squares
(x-4)²=-2y+15
(x-4)²=-2(y-15/2)------->(x-4)²=-2(y-7.5)
the answer is<span>
(x−4)2=−2(y−7.5)</span>
