Answer:
≥ and ≤ will both be solid dots, as it includes the number
x ≥ -7 is everything greater than -7; x ≤ 4 is everything less than 4.
to include both, you'd click -7, drag right, and stop at 4
Answer:
32 ÷ 8 + 1 __IS NOT EQUAL TO__ 3² - 1
4² __IS NOT EQUAL TO__ 4 • 2
3(x - 4 + x) __IS EQUAL__ 3x - 4 + x
when x = 4
15 ÷ (1 + 2) ___IS NOT EQUAL TO_ 15 ÷ 1 + 2
3(x - 4 + x) __IS NOT EQUAL TO__ 3x - 4 + x
when x = 2
To determine which relation is a function, we can perform something called the vertical line test. We cover the graph in repeating vertical lines and if one vertical line connects with more than one point of the relation, the relation is not a function.
The relation in the bottom right corner is the only relation that passes the vertical line test.
<em>Answer:</em>
∠WVR = 156
<em>Step-by-step explanation:</em>
Angles in a triangle add up to 180
∴ ∠SRT + RST + RTS = 180
∴ ∠SRT + 109 + 47 = 180
∠SRT = 24
Alternate Angle Theorem
∠SRT = 180 - ∠WVR
24 = 180 - ∠WVR
24 - 180 = - ∠WVR
-156 = - ∠WVR
∠WVR = 156
Have a beautiful day.
We have to find what percent of the audience from the 16-25 age group gave the movie poor rating. There were 113 viewers from this group. There were 7 of them that gave the movie poor rating. We will use the proportion: 113 / 7 = 100% / x% . Then we will cross multiply: 113 x = 700; x = 700 : 113; x = 6.19%. Answer: A ) 6.19%.
