1
+ 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.

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

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.

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

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

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

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%

find the area of the shaded region of the trapezoid.
Answer:
B
Step-by-step explanation:
Area of Trapezoid
Area = (b1 + b2)*h/2
Area = (9 + 13)*11 /2
Area = (22) * 11/2
Area = 121 sqr. units.
Area of the unshaded triangle
Area = 1/2 b * h
Area = 1/2 9 * 11
area = 49.5
Area of the shaded region
Area = 121 - 49.5
Area = 71.5

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

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°Julie says that she can perform a magic trick with numbers. She asks you to pick a whole number, any whole number. Square that number.

Answer:
61°
Step-by-step explanation:
The dotted angke is a right angle which is 90° so,
We can solve for x using algebra

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
