c. 2 + 6 and 10b - 8a.
Answer:
B
Step-by-step explanation:
Option b is our correct answer.
2, 6 , 10b, and -8a.
Given,
2 + 6 + 10b - 8a
We need to find the terms in the expression.
What are terms in an expression?Every expression is made of terms.
Example:
ax² + bx + c + d
ax², bx, c and d are the four terms that make the expression.
Example:
ax² - bx - c - d
ax², - bx, - c and - d are the terms in the expression.
Remember to take the sign along with the terms.
Find the terms in the expression.
We have,
2 + 6 + 10b - 8a
2 - one expression
6 - one expression
10b - one expression
-8a - one expression
Thus,
Option b is our correct answer.
2, 6 , 10b, and -8a.

F(4)= If g(x)=2,x=.??
Answer:
f(4) = -10
x = 0
Step-by-step explanation:
From the graph attached,
For x = 4,
Value of the function will be,
f(4) = y value at x = 4
f(4) = -10
Similarly, for y = g(x) = 2,
x value of the function will be,
x = 0
For which g(0) = 2
Therefore, for x = 0 value of the function will be 2.
g(0) = 2
Answer:
f(4) = -10

Write an English phrase that would translate into the following mathematical expression.
8(2-6)
Which of the following is equivalent to the expression 8(z - 6)??
Answer:
B. 8 times the difference of a number z and 6
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Translate (z - 6)
z = a number z
- = difference
6 = six
(z - 6) = The difference between a number z and 6
Step 2: Translate 8(z - 6)
(z - 6) = The difference between a number z and 6
Since we are distributing the 8, we are multiplying.
8 times the difference of a number z and 6

5(2x - 8) = 90
A.5
B.10
C.13
D.15
Answer:
13
Step-by-step explanation:
5 (2x - 8) = 90
5 × 2x - 8 = 90
2x - 8 = 90 ÷ 5
2x - 8 = 18
2x = 18 + 8
2x = 26
2x/2 = 26/2
x = 13
13 is the answer to the question.
Given the function: f(x) = x2 – 2x How can you restrict the domain so that f(x) has an inverse? What is the equation of the inverse function?
Answer:
B
Step-by-step explanation:
got it right on edge
The domain restriction is x ≥ 1 and inverse function is f⁻¹(x) = 1+√(x+1)
What is Inverse of Function?An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function which gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.
Given:
f(x) = x² – 2x
We can find the inverse function by solving for y:
x = f(y)
x = y² -2y
x +1 = y² -2y +1
x +1 = (y -1)²
√(x +1) = y -1
1 +√(x +1) = y
So, the inverse function is
[tex]f^{-1}[/tex](x) = 1 +√(x +1)
Thus, the minimum value of x for which the original function has this as an inverse is 1.
So, The domain restriction is x ≥ 1 and inverse function is f⁻¹(x) = 1+√(x+1)

What are the coordinates of point Y?
Answer:
(5,-15)
Step-by-step explanation:
X to the midpoint, the x coordinate goes up 2 and the y coordinate goes down 10. So from the midpoint to Y, the x coordinate must go up 2 (making it 5) and the y coordinate goes down 10 (making it -15)

(5)(1/5)=1
Answer: inverse property of multiplication
Step-by-step explanation:
You need to know about the idea of reciprocal numbers. Reciprocal numbers are numbers that multiplied together to get 1 which is also called inverse. This means one number will be itself, and it's reciprocal will be the denominator of a fraction that has 1 as the numerator
If you come across question like [the reciprocal of a] = 1/aSince 1/5 is the reciprocal of 5, and they are multiplied together to get 1. This will be the inverse property of multiplication.

Why does the number 26 not belong with 17, 26, 44 & 65?
Answer & Step-by-step explanation:
This is what is called an arithmetic sequence. An arithmetic sequence adds the same number every time. If we take and subtract the 3rd term from the 4th term, we get 21. However, when we subtract 17 from 26 or 26 from 44, we get 9 and 18 respectively, which is not in keeping with the sequence.
