F(x)=x²-3x-2 then f(-1) is given by​
evablogger [386]

Answer:

f(-1) = 2

Step-by-step explanation:

To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).

f(x)=x²-3x-2 becomes

f(-1)=(-1)² - 3(-1) -2, or

f(-1) = 1 + 3 - 2, or

f(-1) = 2

What is the arc measure of abc in degrees
Virty [35]

<u>Given</u>:

The measure of arc AB is (4y + 6)°

The measure of arc BC is (20y - 11)°

The measure of arc AC is (7y - 7)°

We need to determine the measure of arc ABC.

<u>Value of y:</u>

The value of y is given by

m \widehat{AB}+m \widehat{BC}+ m \widehat{AC}=360

Substituting the values, we get;

4y+6+20y-11+7y-7=360

Adding the like terms, we have;

31y-12=360

Adding both sides of the equation by 12, we have;

31y=372

   y=12

Thus, the value of y is 12.

<u>Measure of arc ABC:</u>

The measure of arc ABC can be determined by adding the measure of arc AB and arc BC.

Thus, we have;

m \widehat{ABC}=m \widehat{AB}+ m \widehat{BC}

m \widehat{AB}+m \widehat {BC}=4y+6+20y-11

                      =24y-5

Substituting y = 12, we get;

m \widehat{AB}+m \widehat {BC}=24(12)-5

                      =288-5

m \widehat{AB}+m \widehat {BC}=283^{\circ}

Thus, the measure of arc ABC is 283°

Factor completely 20x3y + 30x2y2.
Lana71 [14]
Hey!

It looks like you meant: 20x^3y+30x^2y^2
Then, we are going to change the expression, specially the exponents. The reason behind this is because we don't want anything to be cubed. Here's an example: \:a^{b+c}=a^ba^c
=20x^2xy+30x^2yy
Factor out the common term, which is 10x^2y
=10x^2y\left(2x+3y\right)
Done!

Let me know if you have any questions regarding this problem!
Thanks!
