Answer:

f(x) = 38

Step-by-step explanation:

To find f(x), we must evaluate the expression: x^2 - 4x + 6 when x = -4

Let's break this down:

The first part of this equation is x^2. Plug in -4 for x and solve: -4^2 = 16

Next is -4x. Once again, substitute x with -4, and you have: -4(-4) = 16

And finally, the last part of the expression is just 6, which is a constant, so no solving is necessary.

Now take all the parts of your expression and piece them back together:

16 + 16 + 6 should be the final expression you get.

Solve that expression: 16 + 16 + 6 = 38

Plug the answer back into the equation, and you'll get f(x) = 38.

Hope this helps!

Answer:

38

Step-by-step explanation:

Given that,

x = -4

f(x)=x² - 4x +6

so,

f(-4)= (-4)² - 4 . (-4) +6

       =16 +16 +6

        = 38

Graph the equation y=-x. is (5,5) on the line? what is the slope of the line?
bezimeni [28]
You'll actually need to graph for the first segment
but the second part can be solved with algebra

The equation of the line is y(x)=-x

if we test the co0ordinates we can find if the point lies on the line

(5,5)
y(x)=-x

Using the x co-ordinate
y(5)= -5
y=-5

Leaving us with (5,-5)

Because (5,-5) is not (5,5)
This is not a point on the line

The slope of the line is -1

How many 1/4 cup servings of raisins are in 7/8 cups of raisins?
Ostrovityanka [42]

Answer:

7

Step-by-step explanation:

Divide 7/8 by 1/4.  (You divide the "supply" of raisins into 1/4 cup "parts".)

\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} =\frac{7}{1} =7

Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).

The result is 28/8, which can be simplified ("reduced") to 7.
