Answer:
Step-by-step explanation:
f(-7) = 5(-7) - 3 = -35 - 3 = -38
You can factor a parabola by finding its roots: if

has roots
, then you have the following factorization:

In order to find the roots, you can use the usual formula

In the first example, this formula leads to

So, you can factor

The same goes for the second parabola.
As for the third exercise, simply plug the values asking

you get

Add 3 to both sides:

Divide both sides by 1.5:

Answer:
Peanut oil freezes at a higher temperature than olive oil because 3.1 °C > –6.1 °C.
Step-by-step explanation:
Well since 3.1 is greater than -6.1 then it should be Peanut oil freezes at a high temperature. I did the test and I got it right. I hope you do to. :)
Here you go the answer is in the picture
Part 1) Find the measures of angle BGEwe know that
The inscribed angle measures half of the arc it comprises.
so
angle BGE=(1/2)*[arc EB]
Part 2) Find the angle BDG
we know that
The measure of the external angle is the semi-difference of the arcs that it covers.
so
angle BDG=(1/2)*[arc GEB-arc GB]
