Answer:

Step 1: Multiply the whole number by the denominator: 7 × 8 = 56.

Step 2: Add the product you got in Step 1 to the numerator: 56 + 1 = 57.

Step 3: Divide the sum from Step 2 by the denominator: 57 ÷ 8 = 7.125.

Determine the x and y-intercept for -3x + 2y = 12 PLEASEEEE HELPP THANK U

scZoUnD [109]

To find the x-intercept, let y = 0.

You get 4x-0=12

x = 3

x-intercept is (3,0)

----------------------------

To find the y-intercept, let x = 0.

You get 0-2y=12

y = -6

y-intercept is (0,-6)

Fx) = -3x² + 2x - 7, then f(-1) =

Fantom [35]

Given:

The function is

$f(x)=-3x^2+2x-7$

To find:

The value of f(-1).

Solution:

We have,

$f(x)=-3x^2+2x-7$

Putting x=-1, we get

$f(-1)=-3(-1)^2+2(-1)-7$

$f(-1)=-3(1)-2-7$

$f(-1)=-3-9$

$f(-1)=-12$

Therefore, the value of f(-1) is -12.
