Answer:

33°

Step-by-step explanation:

find the missing angle of triangle BAC, then those two angles are equal, because if you go to the angle to the right of C, they are the same size, then slide it down and that would be angle x. Sorry if that was hard to understand.

Which statement describes the effect on the parabola y = x2 - 1 when it is changed to y = x2 +6?

zlopas [31]

Initial:

$y=x^2-1$

Changed to:

$y=x^2+6$

As you can see the change is: from -1 to +6.

In a equation as follow:

$y=x^2+k$

The k is a transformation that moves up or down the graph of the function. If k is changed to a less value the graph moves down, If k is changed to a greather number the graph moves up.

In this case the graph moves up

To find the number of units the graph moves find the difference betwwen values of k:

$6-(-1)=7$

Then, the parabola y=x²-1 is moved 7 units up when it is changed to y=x²+6

2(3b-1)=40<br> Simplify.

timofeeve [1]

Answer:b=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(3b−1)=40

(2)(3b)+(2)(−1)=40(Distribute)

6b+−2=40

6b−2=40

Step 2: Add 2 to both sides.

6b−2+2=40+2

6b=42

Step 3: Divide both sides by 6.

6b/6=42/6

b=7
