Answer:
Step-by-step explanation:
For a function to have an inverse, it has to pass the horizontal and vertical line test, yes both of them. This function does, so we can continue. The first step for finding an inverse is replacing f(x) with y. Then switch the places of x and y.
[tex]x=\sqrt{y-1}[/tex]
Now the next step is to solve for this new y value, which is equivalent to f^-1(x). Square both sides to get rid of the radical.
[tex]x^2=y-1[/tex]
Add 1 to both sides and that is your inverse function
[tex]y=x^2+1[/tex]
Find the slope of the line that
passes through the following
points. (0,0), (-2,-4)
Answer:
m=2
Step-by-step explanation:
math is hard
Answer:
2
Step-by-step explanation:
The equation for finding slope is:
[tex]\frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex]
Plugging in our values of x and y gives us:
(-4 - 0)/(-2-0) =
-4/-2 =

The sum of 6.7 and a number is negative. What is a possible value for that number? Explain.
Answer:
The number must be greater than 6.7. Thus, the sum will be negative.
For example, the number could be 7.
6.7 - 7 = -0.3
The number can be in the range - x ∈ (- ∞ , - 6.7)
We have - the sum of 6.7 and a number is negative.
We have to determine the possible value of that number.
For what range of values of x, the given function is equals to a negative value -y = f(x) = 2x + 10For f(x) to be negative -
f(x) < 0
2x + 10 < 0
2x < - 10
x < - 5
x ∈ (- ∞ , - 5)
According to the question, we have - the sum of 6.7 and a number is negative.
Now -
6.7 + x < 0
x < 6.7
x ∈ (- ∞ , - 6.7)
Hence, the number can be in the range - x ∈ (- ∞ , - 6.7).

Which inequality is represented by this graph?
A. 0>x
B.x>0
C. 0>_x
D.x>_0
Answer:
B. X > 0
Step-by-step explanation:
The dot it at 0, but is not filled in, so that means that it is not equal to.
The arrow is pointing to terms greater than 0 which can be described as (X). Since X is greater than 0, and not equal to 0, we get B as our answer.

what is 9/32 + 7/8 plz help
Answer:
1 5/32
Step-by-step explanation:
First, find common denominators. What you do to the denominator, you must do to the numerator.
First, multiply 4 to both the numerator and denominator of the second fraction:
(7/8)(4/4) = (7 * 4)/(8 * 4) = 28/32
Next, add across:
9/32 + 28/32 = 37/32
Simplify. Turn the improper fraction into a mixed fraction:
37/32 = (32 + 5)/32 = 1 5/32
1 5/32 is your answer.
~
Answer:
37 /32
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 8 and 32 is 32
For the 1st fraction, since 8 × 4 = 32,
7 /8 = 7 × 4
8 × 4 = 28 /32
Likewise, for the 2nd fraction, since 32 × 1 = 32,
9 /32 = 9 × 1
32 × 1 = 9 /32
Add the two fractions:
28 /32 + 9/32 = 28 + 9 /32 = 37 /32
So, 7/8 + 9/32 = 37/32
In mixed form: 1 5 /32

There are five students wearing glasses. There are three more boys than girls wearing glasses. On your worksheet, solve the question and write your answer below. How many boys wear glasses and how many girl wear glasses?
Answer:
Four boys and one girl.
Step-by-step explanation:
Total students wearing glasses = 5
Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.
Girls = x
Boys = x + 3
Total = 5
Calculate:
x + x + 3 =5
2x + 3 =5
2x = 2
x = 1
Boys wearing glasses = (1) + 3 = 4
Girls wearing glasses = 1
