So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!

If f(x) = -5x - 1 and g(x) = x - 6 what is (f g) (7)

Cloud [144]

You have

$(f\circ g)(x) = f(g(x)) \implies (f\circ g)(7) = f(g(7))$

So, we have to compute g(7) and feed it as input to f(x). We have

$g(7)=7-6=1 \implies f(g(7))=f(1)=-5-1=-6$

What is true of an adjustable rate mortgage?

Varvara68 [4.7K]

Answer: B. the interest rate may change depending on the condition of the economy.

Step-by-step explanation:

By definition, in a adjustable-rate mortgage (which can be identified as ARM), the interest rates can fluctuates, this means that it can change periodically.

Therefore, the interest rate is fixed for a period of time and then it varies based on the index it is tied to. This index is set by market situation.

Then, keeping this on mind, the correct answer is the option B, which is: The interest rate may change depending on the condition of the economy.

Pleeeeeeeaaaseee help. I need to find the exterior angle measurement. I will mark brainliest

Mariana [72]

Answer:

2a = 108

Step-by-step explanation:

the 3 angles of the triangle add to 180

lets call the unknown angle in the triangle y

a+10 + y + 44 = 180

we also know that 2a+ y = 180 because it makes a straight line

solve this for y by subtracting 2a from each side

2a +y = 180

y = 180 -2a

now we can substitute this into the triangle equation

a+10 + y + 44 = 180

a+10 + 180 -2a + 44 = 180

combine like terms

-a +234 = 180

subtract 234 from each side

-a = --54

divide each side by -1

a =54

the exterior angle is 2a

2* 54

108
