Identify any x-intercepts for the graph below .
The graph shows f(x) and its transformationg (x)
Which equation correctly modelsg (x)?
g(x) = 3^x-7 – 2
g (x) = 3^x+7 - 2
g(x) = 3^x+2 - 7
g(x) = 3^x-2-7
Answer:
[tex]g(x) = {3}^{x - 2} - 7[/tex]
Step-by-step explanation:
As we can see, the graph of transformation of f(x) is translated to the right and down.
then, g(x) = f(x - a) - b, where a & b > 0.
from the options, there are 4 translated function of f(x).
but on the second option
[tex] {3}^{x + 7} - 2 = {3}^{x - ( - 7)} - 2[/tex]
a < 0, then it's not the answer we need, same as third option that makes only first and fourth left.
from the picture, horizontal asymptote of f(x) is y = 0.
on g(x) horizontal asymptote is y = -b, where -10 < -b < -5.
and from the options that are left, we can see only fourth option that satisfies what we need.

Answer:We have been given that a rectangle has a height to width ratio of 3:4.5.
Let h be height and w be width of rectangle.
We can set our given information in an equation as:
Now we will substitute h=1 in this equation.
We can see that width of rectangle is 1.5 times height of rectangle.
Our one set of dimensions of rectangle will be: height=1 and width=1.5.
We can get many set of dimensions for our rectangle by multiplying both height and width of rectangle by same number.
Multiplying by 5 we will get our dimensions as: height 5 and width 7.5.
Therefore, (1 and 1.5) and (5 and 7.5) dimensions for rectangle will be scaled version of our rectangle.

I searched this on brainly and the answer was wrong. The correct answer is actually 82.88! Thank me later :)
Answer:
The answer is $82.88.
Step-by-step explanation:
Too complicated. Will do explanation later.
Answer: You're correct :3
Step-by-step explanation:
15% of 78.93 ≈ 11.84
78.93 - 11.84 = 67.09
20% of 78.93 ≈ 15.79
67.09 + 15.79 = 82.88
You're correct!

Find the value of x :>
Answer:
x = 61°
Step-by-step explanation:
Since the lower left angle equals to 90°, the other angle on the right must also equal 90°. Subtract 29 from 90° to get 61° as your x value and as your final angle answer.
Answer:
61°
Step-by-step explanation:
The dotted angke is a right angle which is 90° so,
We can solve for x using algebra
90+x+29=180
x+119=180
x=180-119
x=61

L1 and 22 form a linear pair. If m_1 = 4 m22, find the measure of each of the two angles.
Answer:
We conclude that
The angle ∠1 = x = 36°The angle ∠2 = 4x = 4(36°) = 144°Step-by-step explanation:
Given
<1 and <2 form a linear pair
m∠1 = 4m∠2
To determine
Find the measure of each of the two angles.
Important Points about linear pair:
We know that when two lines meet or intersect, we get a linear pair of angles.Linear pairs are basically two adjacent angles that form a line.The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.As
<1 and <2 form a linear pair
m∠1 = 4m∠2
In other words, angle 1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so
[tex]x + 4x = 180[/tex]
[tex]5x = 180[/tex]
divide both sides by 5
[tex]\frac{5x}{5}\:=\:\frac{180}{5}[/tex]
[tex]\:x=36^{\circ }[/tex]
Thus, we conclude that
The angle ∠1 = x = 36°The angle ∠2 = 4x = 4(36°) = 144°A hardware store manager reviews data that shows how well a new product is selling over an 8-week period. The data can be modeled by the equation y = - 13.9x + 103 , where x represents time in weeks and y represents the number of units of the product left in stock. what does-13.9 represent
Answer:
-13.9 represents the slope
It is the number of units of the product left in stock per week
The negative value shows it decreases per week
Step-by-step explanation:
Here, we want to state what the value -13.9 represents
Generally, the equation of a straight line can be represented by the equation
y = mx + c
where m is the slope
In this case, -13.9 represents the slope of the model
The slope is calculated by dividing a change in y by a change in x
With respect to the question, the slope here represents number of units of the product left in stock per week
6 xy × 4 = 2 x72 please koi solutions do
Answer:
y = 6
Step-by-step explanation:
6 * y * 4 = 2 * 72
y = 2 * 72/24 = 6
6xy × 4 = 2 × 72
or, 6xy = 2 × 72/4
or, 6xy = 36
or, xy = 6
6 = 3 × 2 × 1
Hence, x = 3 and y = 2
or, x = 2 and y = 3
or, x = 6 and y = 1
or, x = 1 and y = 6

Mrs. Goerlich deposited $2,000 into a savings account to save for her son's college tuition. • The account earns simple interest. • She did not make any additional deposits or withdrawals. • At the end of 6 years, the account has a balance of $2,780. What is the annual interest rate on this account?
Answer: 6.5%
Step-by-step explanation:
In 6 years the interest earned is:
= 2,780 - 2,000
= $780
The account earns simple interest which means that it increased by the same rate yearly. Yearly increase is:
= 780/6
= $130
Simple interest rate = Interest payment/ Deposit
= 130/2,000
= 6.5%

Ameron works for a car dealership and earns a monthly salary plus a commission for every car he sells.(8.5B) Which equation could be used to find Cameron's total monthly income, M, after selling n cars? M = 500n + 1750 M = 1750n + 2250 M = 1750n + 500 M = 2250n
Answer:
Equation used to calculate monthly income of Ameron is: M = 1750+500n
Step-by-step explanation:
From the question it is give that :
monthly salary of Ameron is 1750 and commission for every car he sells is 500
let n be the Number of car he sells then its total income M of the month is
M = 1750 + 500n
Therefore correct option is (a) i.e., M = 1750+500n

A used book store also started selling used CDs and videos. In the first week, the store sold a combination of 40 CDs and videos. They charged $4 per CD and $6 per video and the total sales were $180. Determine the total number of CDs and videos sold.
I kind of need to know how to solve. I have more q's like this but if I know how to, I might be able to do it.
Answer:
They sold 10 videos and 30 CDs
Step-by-step explanation:
So, you need two different equations-
We will use c to represent CDs and v to represent videos
So-
c + v = 40
4c + 6v = 180
Single out a variable in the first equation-
v = 40 - c
Because this is equal to v, insert it where v is in the second equation-
4c + 6(40 - c) = 180
Multiply-
4c + 240 - 6c = 180
Solve-
-2c + 240 = 180
-2c = -60
c = 30
Now that you know c, use first equation to find v-
30 + v = 40
v = 10
So c = 30 and v = 10

+ 10x + 13 = 4
Answer:
[tex]x = -1[/tex]
Step-by-step explanation:
Equation: [tex]1+10x+13=4[/tex]
Step 1: Balance both parts of the equation.
[tex]1+10x+13=4[/tex]
[tex](10x)+(1+13)=4[/tex]
[tex]10x+14=4[/tex]
[tex]10x+14=4[/tex]
Step 2: Reduce 14 from both parts of the equation.
[tex]10x+14-14=4-14[/tex]
[tex]10x= -10[/tex]
Step 3: Split both sides by 10, because [tex]\mathrn {10x = -10}[/tex].
[tex]\frac{10x}{10} = \frac{-10}{10}[/tex]
[tex]10 / -10 = -1[/tex]
Therefore, x = -1.
The temperature dropped from 23°C to -16°C.
By how many degrees did the temperature drop?
The temperature drops when the temperature goes down from 23°C to -16°C is 39°C.
What is subtraction?It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.
The temperature dropped from 23°C to -16°C.
Then the drop in temperature will be
Temperature drop = 23 - (-16)
Temperature drop = 23 + 16
Temperature drop = 39 °C
