Answer:

Step-by-step explanation:

$-4i+\left(\dfrac{1}{4}-5i\right)-\left(-\dfrac{3}{4}+8i\right)+17i\\\\=-4i+\dfrac{1}{4}-5i+\dfrac{3}{4}-8i+17i\\\\=\left(\dfrac{1}{4}+\dfrac{3}{4}\right)+(-4i-5i-8i+17i)\\\\=\dfrac{1+3}{4}+(-4-5-8+17)i\\\\=\dfrac{4}{4}+0i\\\\=1$

Evaluate the function at each specified value of the independent variable and simplify. (if an answer is undefined, enter undefi

tekilochka [14]

For this case we have the following function:

$h (t) = t ^ 2 - 8t$

What we should do is evaluate the function for the different values of the independent variable.

We have then:

For x = 8:

$h (8) = (8) ^ 2 - 8 (8)$

$h (8) = 64 - 64$

$h (8) = 0$

For x = 1.8:

$h (1.8) = (1.8) ^ 2 - 8 (1.8)$

$h (1.8) = 3.24 - 14.4$

$h (1.8) = -11.16$

For x = x + 8:

$h (x + 8) = (x + 8) ^ 2 - 8 (x + 8)$

$h (x + 8) = x ^ 2 + 16x + 64-8x-64$

$h (x + 8) = x ^ 2 + 18x$

Answer:

The results of evaluating the function are:

$h (8) = 0$

$h (1.8) = -11.16$

$h (x + 8) = x ^ 2 + 18x$

Ooooooo a bonus!!!!!!!!!!!

Answer:

The answer is B:25

Step-by-step explanation:

60 into two classes.

2/3= 40/60,so one class made 40 cookies and the other needs to make 20 cookies. 20 x 1 1/4 = 100/4 = 25.

so the second class needs 25 tablespoons of M&Ms for the cookies.

Plz make me brainliest :)

Solve system of equation using elimination

grigory [225]

First let's get rid of the x by multiplying the tip equation by -2

-2 (-6x - 2y = -4)
+
(-12x - 5y = -13)

Distribute

(12x + 4y = 8)
+
(-12x - 5y = -13)

x cancels out and you're left with

-1y = -5
y = 5

Now solving for x, plug in your y into one of the equations

-6x - 2(5) = -4
-6x - 10 = -4
-6x = 6
x = -1

(-1 , 5) is the solution
