Answer:
Step-by-step explanation:
We are looking for the value of x so that the function has the given value in the following:
1) h(x) = -7x; h(x)=63
From the function given above,
If h(x) = 63, then,
h(x) = 63 = -7x
-7x = 63
Dividing the left hand side and right hand side of the equation by -7, it becomes
-7x/-7 = 63/-7
x = - 9
2) m(x) = 4x + 15; m(x)=7
From the function given above,
If m(x) = 7, then,
m(x) = 7 = 4x + 15
7 = 4x + 15
4x = 15 - 7 = 8
Dividing the left hand side and right hand side of the equation by 4, it becomes
4x/4 = 8/4
x = 2
3) q(x) = 1/2x - 3; q(x) = -4
From the function given above,
If q(x) = - 4, then,
q(x) = - 4 = 1/(2x - 3) =
Cross multiplying,
-4(2x-3) = 1
-8x +12 = 1
Collecting like terms,
-8x = 1 - 12
-8x = -11
Dividing the left hand side and right hand side of the equation by -8, it becomes
-8x/8 = -11/-8
x = 11/8
The factors are the following : 1, 2, 4, 7, 14, 28.
Answer:
So she can predict that she will be 39 out of 40 times she will be on time.
Step-by-step explanation:
The light rail service claims that it on time 98% of the time .
Given the girl takes light rail service 40 times per month .
Assuming the statement given by the light rail serve is correct 98% of 40 times the girl reaches on time , which is 39 times.
So she can assume that she will be 39 out of 40 times she will be on time.
No the light rails is not accurate if she was late 6 times out of 40 times in a month. Because by the statement given by light rail service she can miss a maximum of 1 time .
