Step-by-step explanation:

Step 1: Define

f(x) = -2x² + 3x - 6

f(3) is x = 3 for the function f(x)

Step 2: Evaluate

Substitute in x [Function]: f(3) = -2(3)² + 3(3) - 6
Exponents: f(3) = -2(9) + 3(3) - 6
Multiply: f(3) = -18 + 9 - 6
Add: f(3) = -9 - 6
Subtract: f(3) = -15

Recall that the perimeter of a figure such as the one to the right is the sum of the length of its sides. Find the perimeter of

VashaNatasha [74]

Answer:

perimeter: 90z+176

Explanation:

perimeter = measure of all length sides

perimeter for this shape:

45z + 40 + 15z + 48 + 20z + 60 + 10z + 28

group terms like this ↓

45z+15z+20z+10z+40+48+60+28

addition of terms ↓

45z+15z+20z+10z+176

this is how final result would look ↓

90z+176

If the translation T maps point A(7,2) onto point A′(5,5), what is the translation T?

VMariaS [17]

Answer:

< - 2, 3 >

Step-by-step explanation:

To translate from A(7, 2) to A'(5, 5 )

There is a shift of - 2 units in the x- direction and a shift of + 3 units in the y- direction.

That is (x, y ) → (x - 2, y + 3 ) ← translation rule, or

The translation is < - 2, 3 >
