Show your steps Please :3
Answer:
x = 3.75 or [tex]3\frac{3}{4}[/tex]
Step-by-step explanation:
17 = -13 - 8x
add 13 to both sides
17 + 13 = -13 + 13 + 8x
30 = 8x
divide both sides by 8
30/8 = 8x /8
3.75 = x

The range of a relation is
A. the output (y) values of the relation
B. the input (x) values of the relation
C. a set of points that pair input values with output values
D. x and y values written in the form (x, y)
A.
Step-by-step explanation:
Range of a function is the value that we get when a function is solved.
Say, f(x) = y.
We say this "set of x is domain" whereas "set of y is range".
Suppose,
set A = {1,2} & set B = {1,2,3} & f(x) = y
Let,
f(1) = 1, & f(2) = 2.
What we get is that there is no x for 3.
We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.
Juan drove from his mother's house to his apartment at Arkansas Tech. After driving for 20 minutes, he was 62 miles away from his apartment. After driving for 32 minutes he was only 38 miles away. The time driving and the distance away from his apartment form a linear relationship. What is the independent and dependent variables
Given:
After driving for 20 minutes, Juan was 62 miles away from his apartment.
After driving for 32 minutes Juan was only 38 miles away.
The time driving and the distance away from his apartment form a linear relationship.
To find:
The independent and dependent variables.
Solution:
If the value of a variable depends on the another, then it is called dependent variables.
If the value of a variable does not depend on the another, then it is called independent variables.
In the given problem, the distance of Juan from his apartment depends on the time he drove. So,
Dependent variable = Distance of Juan from his apartment in miles.
Independent variable = Time he drove

What is polynomial?Polynomial equation is equation of independent variables.
Here, questions seems to be incomplete.
In polynomial, it can be of maximum endless number of term or minimum 1 term. Marcus can add any number or repeat any number. And if he revised the old number than the number could be -3mn^3 and -5mn^3.
Thus, Marcus has to add -3mn^3 and -5mn^3 to complete the polynomial.

Rachel and four friends were going to the movies. Each ticket cost $11 and then they bought 2 popcorns at $3.75 each, and they each bought their own soda at $2.75 each. How much money did they spend total for their trip to the movies? If they decide to split the bill, how much will they each pay?
Answer:
Total amount spent [tex]=\$73.5[/tex]
If they decide to split the bill, amount paid by each of the person [tex]=\$15.25[/tex]
Step-by-step explanation:
Cost of each movie ticket = $11
Cost of 5 tickets = 5(11)= 55
Cost of each packet of popcorns = $3.75
Cost of two packets of popcorns = $2(3.75) = $7.5
Cost of each soda = $2.75
Cost of five sodas = $5(2.75) = $13.75
Total number of persons (Rachel and four friends) = 5
Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]
If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]

If I got a 60 on a test , and I have a 92 in that class , what will my grade be ? (please answer i am stressing so much I might get gray hairs)
Answer:
There's no way to answer this question 100% accurately, because we don't know your teacher's grading scale, or how much tests and quizzes are weighted for your grade in the class. That being said, one test shouldn't bring your grade down too much. As the year goes on, and more assignments are put in the gradebook, it will even out. If you get a 100 percent on 3 tests, and a 60 percent on one test, it evens out to a 90 percent.

The low temperatures in two cities are being compared. In City 1, the range in temperature is 20°F and the IQR is 7°F.
In City 2, the range in temperature is 15°F and the IQR is 7°F.
What might you conclude about the cities based on the ranges and interquartile ranges?
B.The weather pattern in City 2 is more consistent than the weather pattern in City 1
explanation:
Range and interquartile range (IQR) measures the spread of data. Range measure the overall spread and IQR measures spread in 50% of data.
Range is calculated by differencevof maximum and minimum value whereas IQR is calculated by difference of First quartile and third quartile.
Since, the range and IQR is less for City 2 as compared to City 1.
Thus ,weather pattern of City 2 is more consistent as compared to City 1.

A music store is receiving a shipment of Ipads. Each box comes with 12 white, 12 black and 24 grey
Ipads. They already have 23 white, 16 black and 22 grey Ipads. If the store is receiving 5 boxes, how
many of each color Ipad will they have?
Answer:
142 Grey, 83 white, 76 black
Step-by-step explanation:
If you were to take 5 boxes and put 24,12,12 in each, then multiply each number by 5 you wpuld get 120 Grey, 60 white and 76 black. Then you would add what they already have 120 Grey + 22 Grey is 142 grey, 60 white + 23 white is 83 white, and 60 black + 16 black is 76 black.
((8y-3x)/(4))/(4)-(-7+5x)/(3)
Let's simplify step-by-step
8y-3x/4/4 -(-7+5x/3)
Distribute:
=-3/16 x +1/2 y+-5/3 x+7/3
Combine like terms:
=-3/16x+1/2 y +-5/3x+7/3

You can find this by using the pythagorean theorem.
The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.
The hypotenuse is the longest side, which is opposite the right angle.
The other 2 sides are the legs.
Here, the hypotenuse is BC which is 17.
AC is one leg. We are trying to find the other leg.
So you set up the equation AB^2+ 15^2 = 17^2.
This simplifies to AB^2 + 225 = 289.
AB^2 = 64.
AB = 8.

Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,
2/1÷4/5
But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)
2/1×5/4

Let's see what to do buddy...
_________________________________
[tex]x - 9y = 17[/tex]
Subtract the sides of the equation minus x
[tex] - 9y = 17 - x[/tex]
Divided the sides of the equation by -9
[tex] \frac{ - 9}{ - 9}y = \frac{17 - x}{ - 9} \\ \\ [/tex]
[tex]y = \frac{ - (17 - x)}{9} \\ [/tex]
[tex]y = \frac{x - 17}{9} \\ [/tex]

And we're done.

Answer: y=8 m=5
Step-by-step explanation:
Answer:
1. 3.125
2. 4.5
Step-by-step explanation:
1. Since the figures are similar, the number you divide from one triangle to the other is the same, no matter the side length. 5(x) = 8 so 5/x = y. If x = 1.6, then y equals 3.125.
2. The same thing here. 4/x = 3 and 6/x = m. In the first equation x would be 1 1 1/3. 6/ 1 1/3 is the same as 6 x 3/4 which is 18/4 or 4.5.
