Please help! Brainliest! How are the functions y = 2x2 and y = 2x2 + 7 related? How are their graphs related?
A. Each output for y = 2x2 + 7 is 7 less than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated down 7 units.
B. Each output for y = 2x2 + 7 is 7 greater than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated up 7 units.
Answers
Option B is correct.
We have the two equations -
[tex]y= 2x^{2}[/tex]
[tex]y=2x^{2} +7[/tex]
We have determine how are these functions related and how are their graphs related.
What type of conic section is represented by equation -y = [tex]$x^{2}[/tex] ?A parabola is represented by the equation y = [tex]$x^{2}[/tex].
According to the question, we have -
[tex]y= f(x) = 2x^{2}[/tex]
[tex]y=g(x)=2x^{2} +7[/tex]
Refer to the image attached for graphs.
Now -
g(x) - f(x) = [tex]2x^{2} +7-2x^{2}[/tex] = 7
Therefore - Each output for y = g(x) is greater than the corresponding output of y = f(x).
From the graph it is clear that the graph of y = g(x) is the graph of
y = f(x) translated up 7 units.
Hence, Option B is correct.

Use the literal equation m=5/4n-7 to find m when n =40
Help plz
Answers
Answer: 5/153
Step-by-step explanation:
Well, you'd just have to plug in 40 for n.
5/(40*4 - 7) = m
5/(160-7) = m
5/153 = m
An equation is formed of two equal expressions. As per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The value of m from the given equation can be found by substituting the value of n as 7 in the given equation as shown below.
m = (5/4)n - 7
Substitute the value of n as 40,
m = (5/4)40 - 7
m = (5/1)10 - 7
m = 50 - 7
m = 42
Hence, as per the literal equation m=5/4n-7, the value of m when the value of n is 7 is 42.

2·π≈6.00014
Answer:
The radius is 6
Step-by-step explanation:
The circumference of a circle is equal to pi times the diameter. The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius
C=2πr

b. Write the slope, y-intercept form of (a).
PLS HELP
Answers
Answer:
[tex]\displaystyle y=-\frac{a}{b}x+\frac{c}{b}[/tex]
Step-by-step explanation:
The equation of the line, expressed in slope-intercept form is:
[tex]y=mx+y_o[/tex]
Where m the slope and yo the y-intercept.
Since we are given the line in standard form:
ax+by=c
To find the slope-intercept form, we just solve it for y:
[tex]\boxed{\displaystyle y=-\frac{a}{b}x+\frac{c}{b}}[/tex]
Comparing the last equation with the slope-intercept form:
[tex]\displaystyle m=-\frac{a}{b}[/tex]
[tex]\displaystyle y_o=\frac{c}{b}[/tex]
Answer:
ax + by = c
-ax -ax
by=ax+c
then dived both sides by b to get y by itself
y= a/bx +c

Answers
Answer:
6.4 hrs
Step-by-step explanation:
16.5h + 289 = 18.75h + 274.6
16.5h-18.75h = 274.6-289
-2.25h=-14.4
h=14.4/2.25
h=6.4 hrs
check
6.4×16.5=105.6
105.6+289=394.6
18.75×6.4=120

Answers
Answer:
Speed of Jennifer on Sunday [tex]=45[/tex] mi/hr
Step-by-step explanation:
Let speed of Jennifer on Saturday be x mi/hr
On Saturday morning, it took Jennifer 3.6 hours to drive to her mother's house for the weekend.
Distance travelled by Jennifer on Saturday = Speed × Time [tex]=3.6x[/tex] miles
Speed of Jennifer on Sunday = [tex](x-5)[/tex] mi/hr
On Sunday evening, due to heavy traffic, it took Jennifer 4 hours to return home.
Distance travelled by Jennifer on Sunday = Speed × Time [tex]=4(x-5)[/tex] miles
As distance is obviously same on both Saturday and Sunday,
[tex]3.6x=4(x-5)\\3.6x=4x-20\\20=4x-3.6x\\20=0.4x\\x=\frac{20}{0.4}\\ x=50[/tex]
Therefore,
Speed of Jennifer on Sunday = [tex](50-5)=45[/tex] mi/hr

Answer
1360
Step-by-step explanation:
4x10 is 40 so you'd have to multiply 40x34 which is 1360
136×10 is the amount of water used by the airplane to deliver 34
trips.
What is Multiplication?Multiplication is a method of finding the product of two or more numbers
Given that Airplanes are sometimes used to fight fires.
A certain airplane can deliver 4 x 10 liters of water in one trip.
We need to find how much water can the airplane deliver in 34
trips
Let us find the water used for one trip.
1 trip is 4 x 10 liters which is 40 litres.
Now we have to find for 34 trips.
We have to multiply 34 with 40 litres
34×40
Thirty four times forty
1360
Now we have to convert it to the scientific notation 136×10
Hence, 136×10 is the amount of water used by the airplane to deliver 34
trips.

Homework #1-18: Answer yes or no, if no give the reason
1) Is A ⊆ B given A = silver, B = {gold, silver, diamond}
A is not a set, so it can’t be a proper subset.
Answer: no, because A is not a set
3) Is C ⊆ D given C = {Phoenix}, D = {Phoenix, Glendale, Peoria, Scottsdale}
I need two rules to work.
C is a set so rule 1 is satisfied.
Every element of C is also an element of D, so rule 2 is satisfied.
Answer: yes
5) Is A ⊆ B given A = {2,3} , B = {1,2,3,4,5}
I need two rules to work.
A is a set so rule 1 is satisfied.
Every element of A is also an element of B, so rule 2 is satisfied.
Answer: yes
7) Is A ⊆ B given A = a, B = {| }
A is not a set, so it can’t be a proper subset.
Answer: no, because A is not a set
9) Is A ⊆ B given A = { }, B = {1,2,3,4,5}
Answer yes: the empty set is a subset of every set.

This is not a true statement. The sets are equal and this symbol does not allow sets to be equal.
Answer: no, sets are equal
15) Is C ⊂ D given C = {1,2,3,4,5}, D = {1,2,3,4}
Answer: no, C is not contained in D, so this is not true

Answer:
26 coaches and 143 players
Step-by-step explanation:
we can set up a proportion: [tex]\frac{coaches}{players}[/tex]
Our original proportions, 4/22 and 2/11 simplify to 2/11
We basically need a proportion that simplifies to 2/11, So let's simplify each proportion
24 coaches and 120 players: 24/120 simplified ⇒ 1/5
26 coaches and 143 players: 26/143 simplified ⇒ 2/11
28 coaches and 168 players: 28/168 simplified ⇒ 1/6
30 coaches and 180 players: 30/180 simplified ⇒ 1/6
The porportion, 26 coaches and 143 players simplifies to our orginal
proportion, 2/11, therefore it is proportional
