Answer:

32.8

Step-by-step explanation:

We are given the expression:

39/y +5y

We know that y is equal to 5. Therefore, we can substitute 5 in for every y.

39/5 + 5(5)

Solve from left to right according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, divide 39 by 5.

7.8+5(5)

Next, multiply 5 and 5

7.8+25

Finally, add 7.8 and 25

32.8

Writing an Equa
kakasveta [241]

Answer:

Step-by-step explanation:

(3,1) lies below the vertex, so the parabola opens downwards.

Equation for a down-opening parabola with vertex (2,3):

y = a(x-2)² + 3, a<0

Plug in (3,1) and solve for a:

1 = a1² + 3

a  = -2

y = -2(x-2)² + 3
