Answer:
x + y <u>></u> 15
10x + 5y <u><</u> 100
we will put it in terms of y
y <u>></u> 15 - x
and
5y <u><</u> 100 - 10x
y <u><</u> 20 - 2x

Answer:
cot∅ = (-2√30)/7.
Step-by-step explanation:
Given the value of csc∅ = -13/7 and ∅ is in quad III.
We know y = r sin∅ and r > 0. So csc∅ = r/y = -13/7 = 13/(-7).
It means y = -7, r = 13.
We know x² + y² = r².
x² = r² - y²
x² = (13)² - (-7)² = 169 - 49 = 120.
x = √120 = 2√30.
we know cot∅ = x/y = (2√30)/(-7) = (-2√30)/7.
Hence, cot∅ = (-2√30)/7.
Answer:
With the increase of the value of a ,the value of the expression 20+a will also increase.
Step-by-step explanation:
The answer is D because the slope formula shows that the answer is C or D and C would not make sense because the y intercept is impossible
Answer:
#7 = 430
#9 = 16
#11 = 930
Step-by-step explanation:
7 to the power of 2 is 49 / 49+3 is 52 / 52-9 is 43 / 43x10 is 430
66 divided by 11 is 5 / 5 +3 is 8 / 8 X2 is 16
18 -3 is 15 / 15 + 3 is 18 / 18 to the power of 2 is 324 / 324 - 14 is 310
310x3 is 930
