Answer:
A
Step-by-step explanation:
I believe it is A because for perpendicular lines the slope must be the reciprocal and have the opposite sign. The y-intercept 2 matches the coordinates (-2, 2). The second number, 2, is the y coordinate.
The function that Ngozi's salary s(t) in dollars, t years after she starts to work as an interpreter is given by
.
What is a function?
- A function in mathematics from a set X(ax) to a set Y allocates exactly one element of Y to each element of X(ax).
- A relation between a collection of inputs and labor is known as a function.
You can use the fact that the raise is done on the previous year's salary.
Let the initial salary be P = $24000
After 1 year, her salary increased by R = 3.5% which, thus,
Total salary = P + increment
Similarly going on, we get
(we can say)
Putting values of P(value of P) and R(value of R), we get

Thus,

It takes the son one and half hours to clean the house. To find this you need the equations F+S=2 and F+1=S. (F=father and S=son) You take the F+1 and substitute it in for S in F+S to get F+(F+1)=2. Then you combined like factors, 2F+1=2, and simplify to get F=.5hr. After this you plug .5 in to F+1=S to get (.5)+1=S, meaning it takes the son 1.5 hour to clean the house.
Answer:
x = -10
y = 13
Step-by-step explanation:
-3x + 2y = 56
-5x - 2y = 24
__________ +
-8x____ = 80
x______= 80/-8
______x = -10
-3x + 2y = 56
-3(-10) + 2y = 56
30 + 2y = 56
2y = 56 - 30
2y = 26
y = 26/2
y = 13
So if 44=8 and 33=x, solve for x.
The problem would look like this : 44mm = 8m
33mm = x
You would cross multiply giving you this : 44x = 264
Then divide 264 by 44 to isolate x, then you should get this : x = 6
6m will be your answer.
