Answer:
A. $3.50 is input, Gallon of Gasoline is output B. The form is a function of y=3.50x C. $7.00-2 Gallons. This shows that for 7 dollars you can get 2 gallons of gasoline.
Step-by-step explanation:
The linear equation will be y = 3.50 x. Then the total cost 'y' of the 'x' gallons of gasoline.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
At a gas station, a gallon of gasoline costs $3.50. The relationship between the dollar cost of gasoline and the gallons purchased can be described with a function.
Let 'x' be the number of gallons of gasoline and 'y' be the total cost. Then the equation is given as,
y = 3.50 x
The linear equation will be y = 3.50 x. Then the total cost 'y' of the 'x' gallons of gasoline.

Han earns $33.00 for babysitting 4 hours. At this rate, how much will he earn if he
babysits for 7 hours. You may solve with any method but you must show your work.
Step-by-step explanation:
First, you want to find the unit rate, or how much Han earns per hour
You can do this by setting up an equation
x= amount earned per hour
4x= 33 Initial equation
4x/4 = 33/4 Isolating the variable
x = 33/4 = 8 1/4 = 8.25 The unit rate
Now you want to set up a new equation to find out how much he makes for 7 hours
x= amount earned per hour
y = total amount earned
y = 7x Initial equation
y = 7 ( 8.25) Substitution
y = 57.75 The answer
Han earns $57.75 for every 7 hours
Checking the answer....
y = 7x
57.75 = 7x Substitute y instead
57.75/7 = 7x/7
8.25 = x
Your answer should be correct

A committee must be formed with 4 teachers and 5 students. If there are 7 teachers to choose from, and 15 students, how many different ways could the committee be made?
Answer:
Step-by-step explanation:
There are a total of 10 persons (6 teachers + 4 students) from which a committee of 5 is to be formed. This can be done in 10C5 ways.
The number of ways that a committee can be formed with no students in it is to select 5 teachers out of the pool of 6 teachers available. This can be done in 6C5 ways.
Therefore the total number of ways that the committee can be formed with at least one student in it is 10C5 - 6C5.
10C5 = 252
6C5 = 6
Therefore the required number of ways = 246

m∠1 + 121 = 180 [Sum of linear angles = 180°]
True.
Option G
121 + m∠2 + 33 = 180
False. Because 121° is not an interior angle of the given triangle.
Option H
33 + m∠1 = 92
True.
Measure of exterior angle of a triangle is equal to the sum of he measure of the non adjacent interior angles.
Option J
121 + 92 + m∠3 = 360°
True.
Sum of the exterior angles of triangle is 180°.
Find the value of x.
x=
(no need to do the classifying.)
Answer:
35° (Verified Answer) ✅Step-by-step explanation:
Well, we know that all three angles of a triangle add up to 180°, we set the three equations added together equal to 180°.
180 = x + 10 + 3x - 5 + x
We can simplify this to:
180 = 5x + 5
Now, all we need to do is solve.
Subtract 5.
175 = 5x
Divide by 5
x = 35°
Now, we must check this solution by substituting our solution for x in for x, to see if the values equal.
180 = 35 + 10 + 3 (35) - 5 + 35
180 = 45 + 3 (35) - 5 + 35
180 = 105 + 45 - 5 + 35
180 = 150 - 5 + 35
180 = 150 + 30
180 = 180 ✅
Howie works at a petting zoo. He fed a piglet 1/5 of a bottle of milk then gave 3/4 of what was left to the calf. How much of the bottle of milk did the calf drink
Answer:
[tex]\frac{3}{5}[/tex]th part of the bottle will be drunk by the calf.
Step-by-step explanation:
Part of the bottle fed by the piglet = [tex]\frac{1}{5}[/tex]
Milk left in the bottle = 1 - [tex]\frac{1}{5}[/tex]
= [tex]\frac{5-1}{5}[/tex]
= [tex]\frac{4}{5}[/tex]
Milk drunk by the calf = [tex]\frac{3}{4}[/tex]th of the left part
= [tex]\frac{3}{4}\times \frac{4}{5}[/tex]
= [tex]\frac{3}{5}[/tex]th part of the bottle
Therefore, [tex]\frac{3}{5}[/tex]th part of the bottle will be drunk by the calf.

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds, t, by the equation d=0.15. How fast is it flying? Do not include units
Answer:
0.15
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
Hence the airplane is flying at 0.15

What is the length of DE in the image provided? (Please explain so I can understand in the future)
A. DE=4
B. DE=5
C. DE=6
D. DE=7
==========================================================
Explanation:
We have these three facts:
The arc markings on angles C and D indicate those angles are congruent. We can say that angle ACB = angle EDB.Another pair of congruent angles are angle ABC and angle EBD. These are vertical angles. Lastly, we have a pair of congruent sides AB and BE because of the tickmarks.Those three facts allow us to use the AAS (angle angle side) congruence theorem to prove that triangle ABC is congruent to triangle EBD.
Then by CPCTC (corresponding parts of congruent triangles are congruent), we know that AC = DE. Note how 'A' and 'C' are the first and last letters of ABC; similarly, 'E' and 'D' are the first and last letters of EBD. Segment ED is the same as segment DE.
So to find the length of DE, we need to find the length of AC. To do that, we need the value of x.
----------------
Recall earlier that AB = BE. Use this to find x
AB = BE
1.5x = 3x-6
1.5x-3x = -6
-1.5x = -6
x = -6/(-1.5)
x = 4
Now we can find the length of AC
AC = x+3
AC = 4+3
AC = 7
This must mean DE = 7 as well.
Answer:
DE=7

Together, Ashley and Gabby watched a total of 14 hours of television over the weekend. Ashley watched 6 times as many hours as Gabby. How many hours of television did they each watch over the weekend? Write and solve a system of equations by using the substitution method. Be sure to define your variables.
Answer:
The number of times over the Weekend that:
Ashley watched TV = x = 12 hours
Gabby watched TV = y = 6 hours
Step-by-step explanation:
Let us represent:
The number of times
Ashley watched TV = x
Gabby watched TV = y
Together, Ashley and Gabby watched a total of 14 hours of television over the weekend.
= x + y = 14..... Equation 1
x = 14 - y
Ashley watched 6 times as many hours as Gabby.
x = 6y
Using substitution method
We substitute 14 - y for x
14 - y = 6y
14 = 6y + y
14 = 7y
y = 14/7
y = 2 hours
Solving for x
x = 14 - y
x = 14 - 2
x = 12 hours
Therefore:
The number of times over the Weekend that:
Ashley watched TV = x = 12 hours
Gabby watched TV = y = 6 hours

Answer:
Step-by-step explanation:
The two angles would equal 180°.
(7x - 5) + (5x + 19) = 180
Combine like terms.
12x + 14 = 180
Simplify by isolating the variable
12x + 14 = 180
------ -14 ----------
12x = 166
Divide both sides by 12
x = 13.833
To nearest tenth, 13.8
Use the Zero Product Property to find the x-intercepts for y=3x2−7x+4
Answer:
x = [tex]\frac{4}{3}[/tex], x = 1
Step-by-step explanation:
To find the x- intercepts, let y = 0 , that is
3x² - 7x + 4 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 4 = 12 and sum = - 7
The factors are - 3 and - 4
Use these factors to split the x- term
3x² - 3x - 4x + 4 = 0 ( factor the first/second and third/fourth terms )
3x(x - 1) - 4(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(3x - 4) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
3x - 4 = 0 ⇒ 3x = 4 ⇒ x = [tex]\frac{4}{3}[/tex]
x- intercepts are x = [tex]\frac{4}{3}[/tex] , x = 1
([tex]\frac{4}{3}[/tex], 0 ), (1, 0 ) ← in coordinate form

Answer:
12 mountain bikes
Step-by-step explanation:
1200m+800k=30400
m+k=32
k=32-m
Now solving with substitution we get:
1200m+800(32-m)=30400
1200m+25600-800m=30400
400m=4800
