Answer:
x = 8
Step-by-step explanation
Complimentary angles have a sum of 90*. Thus when adding the two equations together, we must get 90*.
7x + 17 + 3x - 7 = 90 Combine like terms
10x + 10 = 90 Subtract 10 on both sides
10x = 80 Divide both sides by 10
x = 8
Answer:
Step-by-step explanation:
(-9/6) / (3/-2) ; reciprocal of -3/2 = - 2/3
so
(-9/6) * (-2/3)
= 18/18 (negative times negative equals positive)
= 1
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.

Answer:
13.6 hours
Step-by-step explanation:
To find the mean you first add all the numbers together, in this case 68. Then you have to divide this by the number of scores you added, which is 5. So 68/5= 13.6
You would round the seven to an eight because the 8 next to is is closer to 10 and gives it more value than 5. when you're done it would be rounded to 3.68 because you want to find a number rounded to the nearest tenth so you'd use the extra number (8) to make the final product larger than smaller. it would stay a seven if it was lower than 5.
