Answer:

37

Step-by-step explanation:

substitute the given values for x and y into the expression

4x² + 2y

= 4(3)² + 2(\frac{1}{2} )

= 4(9) + 1

= 36 + 1

= 37

A function assigns the values. The correct option is C, x=-6.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

A.) When the value of x is -12,

f(-12) = 2/3(-12) + 7 = -1

g(-12) = 2(-12) + 15 = -9

B.) When the value of x is -9,

f(-9) = 2/3(-9) + 7 = 1

g(-9) = 2(-9) + 15 = -3

C.) When the value of x is -6,

f(-6) = 2/3(-6) + 7 = 3

g(-6) = 2(-6) + 15 = 3

D.) When the value of x is -3,

f(-9) = 2/3(-3) + 7 = 5

g(-9) = 2(-2) + 15 = 11

Hence, the correct option is C, x=-6.

Hello! Please help thanks

Answer:

A. \frac{5}{13}

Step-by-step explanation:

Hi there!

We are given right triangle PQR, with PR=5, RQ=12, and PQ=13

We want to find the value of sin(Q)

Let's first recall that sine is \frac{opposite}{hypotenuse}

In reference to angle Q, PR is the opposite side, RQ is the adjacent side, and PQ is the hypotenuse

So that means that sin(Q) would be \frac{PR}{PQ}

Substituting the values of PR and PQ gives sin(Q) as \frac{5}{13}, which is A

Hope this helps!
