If q(x)=7x^2-1 find q(-9)

liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:

$q(x)=7x^{2} -1$

$q(-9)=7(-9)^{2} -1$

$q(-9)=7(81)-1$

$q(-9)=566$

Now we know that q(-9) is equal to 566.

A triangle with a 135° angle

GuDViN [60]

Answer:

The 135 external angle means its corresponding internal angle is (180–135) 45 degrees. The other internal angle of 65 plus the 45 is 110 degrees. Since the sum of degrees in the angles in a triangle is 180, the other interior angle is (180–110), or 70 degrees.

This is really simple i just need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It will stay the same.

$\frac{2(4)}{4} = 2$
$\frac{2(3)}{3} = 2$
$\frac{2(2)}{2} = 2$
$\frac{2(1)}{1} = 2$
No matter what you multiply 2 by, dividing it by the same number cancels it out, always leaving you with 2.
