What is the measure of angle 42
O 30°
O 420
O 120°
O 1389

42 degrees

Step-by-step explanation:

<3 and <4 form a straight line so their sum is 180 degrees

<3 + <4 = 180

23x + 7x = 180

Combine like terms

30x = 180

Divide each side by 30

30x/30 =180/30

x =6

We want to find <4

<4 = 7x

    = 7*6

<4 = 42 degrees

50-60=10

step-by-step explanation:

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
