Hope it helps!!!!!which expression is equivalent to (3c)-2?
Answer:
Assuming that the notation there is meant as:
[tex](3c)^{-2}[/tex]
then the answer would be 1/(9c²)
If the -2 is indeed just subtraction and not an exponent, then it is simply 3c - 2
The expression equivalent to 1/9c².
What is expression?An expression is a set of terms combined using the operations +, – , x or for example 4 x − 3 or x 2 – x y + 17 .
An equation states that two expressions are equal in value,
for example 4 b − 2 = 6 .
Given:
[tex](3c)^{-2}[/tex]
To make the power positive, just do the reciprocal
=1/ (3c)²
=1/9c²
Hence, the expression
[tex](3c)^{-2}[/tex] is equivalent to 1/9c².

Literally have been at this for 20 minutes PLEASE HELP!!!!
Step-by-step explanation:
first: if we add 3x+7 and 4x+5, it will total a 180 degree angle. This will allow us to solve for x.
3x+7+4x+5=180
7x+12=180
7x=180-12
7x=168
x=24
now we can also see that angle 6 is the same as the angle 3x+7. and Since we know x=24, we can solve for those angles.
3(24)+7:
72+7=79
So :
<6 =79°

A. {-2, 2}
B. -2 < y< 2
C. y> 0
D. yis all real numbers.
Given:
The graph of a function.
To find:
The range of the function.
Solution:
Range is the set of y-values or output values.
From the given graph it is clear that,

Graph? Which is linear
Answer:
Below
Step-by-step explanation:
1. Linear because it is of the form y = mx + b. The variable x is of the first degree.
The coefficient of x (1/3) ( = slope) is positive so it is increasing.
2. This is non-linear because the variable x is an exponent.
3. Because its of the second degree (x^2) - it is non-linear.

Salome is 2 feet 5 inches tall. How many inches tall is Salome?
Answer:
Salome is 29 inches tall.
Step-by-step explanation:
Each feet has 12 inches.
Salome:
Salome is 2 feet 5 inches tall.
Since each has 12 inches, 2 feet = 2*12 = 24 inches
24 + 5 = 29 inches.
So Salome is 29 inches tall.

Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle. He spent 2 hours repairing her bike. Which expression would be used to correctly calculate the amount Roberta owes him?
a.(2 × 25) + 105
b.(105 x 2) + (25 x 2)
c.2 x (25 + 105)
d.2 x 25 × 105
Answer:
a.(2 × 25) + 105
Step-by-step explanation:
Let the number of hours spent repairing the bike = x
Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle.
Therefore, our algebraic expression
= $25× x + $105
= 25x + 105
We were told in the question that He spent 2 hours repairing her bike.
Hence:
25 × 2 + 105
Therefore, the correct option is option a
a.(2 × 25) + 105
f(x) = 5x – 10 and g(x) = x – 16. Which of the following represents h(x) = f(x) + g(x)? h(x) = 6x – 16 h(x) = 6x – 26 h(x) = x – 26 h(x) = x – 16
Answer:
h(x)=6x-26
Step-by-step explanation:
f(x)=5x-10
g(x)=x-16
h(x)=f(x)+g(x)=(5x-10)+(x-16) = 6x-26

Answer:
The answer is y = 6x + 9.
-
Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Slope-intercept: [tex]y = mx + b[/tex]
---
☆We need to find the slope first. So just plug in according to the slope formula!
[tex]m = \frac{ - 3 - 3}{ - 2 - ( - 1)} = \frac{ - 6}{ - 1} = 6[/tex]
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
[tex]y = mx + b \\ 3 = 6( -1 ) + b \\ 3 = - 6 + b \\ \frac{ + 6 = + 6 \: \: \: \: \: \: \: \: \: \: }{9 = b \: \: \: \: \: \: \: \: \: \: \: } [/tex]

☆Now all we need to do is plug in and we are done!
[tex]y = 6x + 9[/tex]

Calculate the average monthly expenses for these individuals?
Kelsey spent $350 in May, $432 in June and $420 in July. Her average monthly expenses are:____
Michael spent $700 in April and May and $800 in June and July. His average monthly expenses are:____
$420+$350+$432=kelsey's monthly expenses
$700+$800=Micheal's Monthly expenses
Michael's average monthly expenses are $750.
What is the average?The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
Given that, Kelsey spent $350 in May, $432 in June and $420 in July.
Now, average monthly expenses are
(350+432+420)/3
= 1202/3
= 400.67
Michael spent $700 in April and May and $800 in June and July.
Here, (700×2+800×2)/4
= (1400+1600)/4
= 3000/4
= $750
Therefore, Michael's average monthly expenses are $750.
