Step-by-step explanation:
Given Function
f(x) = 2.5x + 150
f^-1(x) = ?
Let y = f(x)
y = 2.5x + 150
Interchanging the role of x and y we get,
x = 2.5y + 150
x - 150 = 2.5y
y = (x - 150) / 2.5
So therefore
f^ -1(x) = (x - 150) / 2.5
Hope it will help :)

What is the equation of the line that passes through the point (5,-2)and has a slope of the fraction 6/5?
Answer:
6x-5y-40 = 0
Step-by-step explanation:
y-(-2)=6/5(x-5)
5(y+2)= 6(x-5)
5y+10 =6x-30
6x-5y-40 = 0
6x-5y-40 = 0 is the answer

Step-by-step explanation:
Given that f(x) = 4x - 7 and g(x) = 4x, find a simplified expression for
f(f(x)).
Given:
[tex]f(x)=4x-7[/tex]
[tex]g(x)=4x[/tex]
To find:
The expression for f(f(x)).
Solution:
We need to find f(f(x)).
[tex]f(f(x))=f(4x-7)[/tex] [tex][\because f(x)=4x-7][/tex]
[tex]f(f(x))=4(4x-7)-7[/tex] [tex][\because f(x)=4x-7][/tex]
Using distributive property, we get
[tex]f(f(x))=4(4x)+4(-7)-7[/tex]
[tex]f(f(x))=16x-28-7[/tex]
[tex]f(f(x))=16x-35[/tex]
Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].
What is the sum of the expression below in standard form?

95,237,000
Answer:
95,237,00
0989,000
955,700
132,200
Step-by-step explanation:
there are no really steps on this you just have to put the numbers in order from biggest to smallest
1. If x = -3 , evaluate : 2x + x + 2x + 5
2. 2 ( 2x + 1) + x = x + 2x + 18
3. 2x + x + 2x = 10 + x
Please help thank you in advance :)
Answer:
1. -10
2.x=8
3. x= 2
Step-by-step explanation:
1. x = 3, 2x+x+2x+5
=2(-3)+(-3)+2(-3)+5
= -6 +(-3)+(-6)+5
= -6 -3 -6 +5 Next you have to use BODMAS rule so first addition
= -6 -3 -1
= -9-1
= -10
2. 2(2x+1)+x=x+2x+18
=4x+2+x=3x+18 then collect like terms:
=4x+x+2=3x+18
=5x+2=3x+18
=5x+2-2=3x+18-2
=5x=3x+16
=5x-3x=3x-3x+16
= 2x=16
2x/2=16/2
x=8
3.2x+x+2x=10+x
=6x=10+x
=6x-x=10+x-x
=5x=10
=5x/5=10/5
x=2

What is the slope of the line that passes through the points (2, 6) and (8, 3)?
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
The slope of a line is the change in the line, it is also called; [tex]\frac{rise}{run}[/tex]. The equation to find the slope of a line is;
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute in the given points;
( 2, 6 ) and ( 8, 3 )
[tex]\frac{3 - 6}{8 - 2}[/tex]
Simplify,
[tex]\frac{-3}{6}[/tex]
[tex]-\frac{1}{2}[/tex]
Elena is binding a small booklet with a spine that is inches long. She uses staples that are -inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?
The question is incomplete as it is missing the length of the book spine and length of the staple.
Assume the question goes thus :
Elena is binding a small booklet with a spine that is 15 inches long. She uses staples that are 0.5 -inch long. If she puts the staples end-to-end through the booklet, without gaps or overlaps between them, how many staples would it take to bind the booklet?
Answer:
30 staples
Step-by-step explanation:
Given that:
Length of book spine = 15 inches
LENGTH of staple = 0.5 inch
Since it is assumed that staples are applied end-to-end on the book without gaps ; the number of staples which will be used is ;
Length of book spine / length of staple
= 15 inches / 0.5 inch
= 30 staples

Step-by-step explanation:
Because both triangles have the same side connected to, which means that that side is congruent to each other and because it tells us that JL and JK are congruent and KM and ML are congruent that means that its sss. Also, it is not giving us an angle to find the congruence so it has to be sss.

Rykers’ regular pay rate is $11.97 an hour. He is paid time-and-a-half for hours worked over 40 hours in a week, including weekend work. He worked these hours from Monday through Saturday last week: 10.25, 6.25, 9.25, 12, 12.25, 6.25. What was his gross pay for the week?
Answer:
$770.65
Step-by-step explanation:
11.97/2=5.985
5.985+11.97=17.96
16.25 x 17.96=291.85
40 x 11.97=478.80
