When 10b=5 is solved for c, one equation is c=(2b-2)^2
Answer:
b= 1/2
c = 1
Step-by-step explanation:
10b = 5
You want to leave the variable b on it's own so you divide both sides by 10
10b/10 = 5/10 --> b = 5/10 or 1/2
Since you have the value of b now, plug it in to solve for the value of c
c = (2 (1/2) - 2)^2
= (1 - 2)^2 Half of 2 is 1, of course
= (-1)^2 (-1 * -1)
c = 1 (a negative times a negative is a positive
So the value of be is 1/2 and c is 1

The inverse of f(x) is a function
Answer:
Step-by-step explanation:
Not always. If, however, the given function passes the "horizontal line test," then the given function has an inverse which is also a function. The horizontal line test consists of drawing a horizontal line through the given graph; if the line intersects the graph in only one place, it "passes," and the given function has an inverse function.
Which question should you expect to be answered with variable data?
How many seventh graders are at school today?
How tall is the Empire State Building?
What is the age of my science teacher?
In what months were my family members born?
Answer:
The correct answer is the last one.
Step-by-step explanation:
Variable data is any kind of information gathered that can be made into a chart or graph representing what was collected. In other words, the data collected must vary.
The first, second, and third answers cannot be made into a chart/graph as it would be a singular number, and not provide varying data (which is required to produce a graph/chart).
The last answer would be correct as one can create a chart as the data collected from that question would vary. For example, five family members could be born in July, six in August, and ten in October. The variable that is "varying" would be these months.
Hope this helps!

(Simplify your answer. Do not include the 5 symbol in your answer.)
minutes can be rented for $26
(Round to the nearest minute as needed)
A linear model
reasonable for this situation
Answer:
(A) The independent variable is time (t) in minutes, and the dependent variable is rental cost (), in dollars. The linear function that models this situation is
R(t) = 30t +8
The time that can be rented for $26 = 1min
Step-by-step explanation:
Based on the information given:
Setup charge on Rent at local copy center = $9
an additional $150 for every 5 minutes. To determine the time that can be rented for $26, let's find the relationship between the rental cost and the time.
For every 5min = $150
For 1 min = $150/5
For t min = 150t/5
Where t = number of minutes of rental time
Rental cost = set up charge + additional cost
Let Rental cost = R(t)
R(t) = 9 + 150t/5
Writing it in form of a linear equation: y = mx + c
R(t) = 150t/5 +9
R(t) = (150/5) ×t + 9
R(t) = 30t + 9
The independent variable is time (t) in minutes, and the dependent variable is rental cost (), in dollars. The linear function that models this situation is
R(t) = 30t + 9
The time that can be rented for $26:
Rental cost = $26
R(t) = 30t +9
26 = 30t +9
26-9 = 30t
17 = 30t
t = 17/30 = 0.57
t is approximately = 1min (nearest minute)
The time that can be rented for $26 = 1min

How many times does 2 go into 5?
Answer:
answer is 2.5 times....
There are 2.5 times does 2 go into 5.
Since, Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that,
To find what times does 2 go into 5.
Now, We can solve as by divide 5 by 2,
⇒ 5 / 2
⇒ 2.5
Thus, A number 5 is 2.5 times 2.

Describe how the graph of y = |x|- 4 is like the graph of y = |x| and how it is different.
Jorge solves the equation 4 x minus (x + 2) + 6 = 2 (3 x + 8) using the steps below. Step 1: 4 x minus x + 2 + 6 = 6 x + 16 Step 2: 3 x + 8 = 6 x + 16 Step 3: 8 minus 16 = 6 x minus 3 x Step 4: Negative 8 = 3 x Step 5: Negative StartFraction 8 Over 3 EndFraction = x BRAINLISEST
Answer:
The solution of the given equation is x = -4
Step-by-step explanation:
Explanation:-
Given expression 4 x - (x +2) +6 = 2 (3 x+8)
Step(i):-
4 x - (x +2) +6 = 2 (3 x+8)
4 x - x -2 + 6 = 6 x + 16
step(ii):-
3 x + 4 = 6 x + 16
subtracting '4' on both sides , we get
3 x + 4 - 4 = 6 x + 16 - 4
3 x = 6 x + 12
Step(iii):-
Subtracting '6x' on both sides , we get
3 x - 6 x = 6 x - 6 x + 12
- 3 x = 12
Step(iv):-
Dividing '-3' on both sides , we get
[tex]\frac{-3x}{-3} = \frac{12}{-3}[/tex]
x = - 4
Final answer:-
The solution of the given equation is x = -4
Verification:-
4 x - (x +2) +6 = 2 (3 x+8)
put x = -4
4 ( -4) - ( - 4 +2) +6 = 2 (3(-4)+8)
-16+2+6 = 2 (-12+8)
-8 = -8

Joshua makes earrings to sell at craft fairs. Each pair of earrings contains the same number of wooden beads as glass beads. For each pair, Joshua spends a total of $0.29 on the wooden beads and $0.11 on the glass beads. How many pairs of earrings, x, can Joshua make if he has $20 to spend on beads?
Answer: 50 pairs.
Step-by-step explanation:
For each pair of earrings, Joshua spends $0.29 + $0.11 in materials.
So he spends $0.40 for each pair of earrings.
If he has $20, we want to know how many times he can spend $0.40.
For this, we take the quotient:
$20/$0.40 = 50
This means that we can sperate $20 into 50 times $0.40.
So he can buy enough material to make 50 pairs of earrings.

You deposit $1000 in an account that pays 4 1/2% annual interest compounded monthly. How much will you have in the bank after 9 years
Answer:
1498.17
Step-by-step explanation:
formula A = P[tex](1 + \frac{r}{100} )^{n}[/tex] where r is the rate of interest compounded and n is the number of times compounded.
r = 4.5 / 12 = 0.375 since it is compounded monthly thus need to divide by 12 months
n = 9 x 12 = 108 ( 9 years in months)
A = 1000[tex](1 + \frac{0.375}{100})^{108}[/tex] = 1498.167
Answer:
Step-by-step explanation:
A = I(1+r/n)^nt
A = ?
I = $1000
r = 4.5% = 4.5/100 = 0.045
n = 12
t = 9
A = 1000(1+0.045/12)^108
A = 1000(1.00375)^108
A = $1498.17
