The value of n is 11.
<u>Step-by-step explanation</u>:
The given expression is (n-9) ÷ 10 = -2
<u>To find the value of n</u> :
- From the expression, it is determined that (n-9) is the numerator and 10 is the denominator.
- Cross multiply the denominator in the left side of the expression to the another side.
The expression becomes (n-9) = (10 -2).
⇒ n-9 = -20
Keep the n term on one side and the constants on other side.
⇒ n = -20+9
⇒ n = -11
Therefore, the value of n is 11.
Answer:
Thx for the points
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
Substitute 50 for y in the formula
5x+10y=800
5x+10*50=800
5x+500=800
5x=800-500
5x=300
x=300/5
x=60
Answer:
1). g(-9) = -81.914
2). Last option
Step-by-step explanation:
1). f(x) = x²
For x = -9
f(-9) = (-9)² = 81
g(x) =
g(-9) =
=
= -
(g - f)(-9) = g(-9) - f(-9)
=
=
=
= -81.914
2). The relation is not a function because this function doesn't passes a vertical line test.
Last option will be the answer.
y=7x+12
Step-by-step explanation:
If you already have to start with 12 the c variable supply’s to 7 cause you don’t know how many people
