Answer:
a. E(a) = (a+1)²
b. E(a + h) = (a+h+1)²
c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h
Step-by-step explanation:
E(z)=(z+1)²
E(a) = (a+1)²
E(a + h) = (a+h+1)²
E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h
The spring concert at a certain high school sold 149 tickets. Students were charged $2 each and adults $6 each. The income from the sale of tickets was $626. How many students and how many adults bought tickets?
The final statement is: 67 student tickets and 82 adult tickets were sold.
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here: Total tickets =149 student ticket=$2 and adult ticket=$6
Tickets sold worth=$626
Let x tickets be bought by students and therefore 149-x be brought by adults then we have
2x+6(149-x)=626
-4x+894 = 626
x=268/4
x=67
∴ x=67 & 149-67=82
Hence, 67 student tickets and 82 adult tickets were sold.

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?
Answer:
$2 more.
Step-by-step explanation:
In this question, we have to find how much more money Victoria is saving.
We know that Jacob saved $174 in 3 months.
We also know that Victoria saved $360 in 6 months.
Lets find how much money they save per month:
Jacob:
174 ÷ 3 = 58
Victoria:
360 ÷ 6 = 60
Jacob is saving $58 per month and Victoria is saving $60 per month.
This means that Victoria is saving $2 more than Jacob per month.

Use the diagram showing m || n, as well as the relationships between interior and exterior angles of ΔABC, to answer the questions.
Angle B is the linear pairs with 60°, so the size is 180-60=120°
Angle ABC is the linear pair with 120°, so the size is 180-120-60°
Angle A corresponds to angle 60°, so they are equal
Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°
Angle ACB is 180-(50+60) = 70°
Answer: ABC is 60
BAC is 50
ACB is 70

The admission tickets to an exhibition at $5 for an adult and $2 for a child. A family of 3 adults and 4 children visited the exhibition. What would be the charge if $50 note was used to buy the tickets?
Given :
The admission tickets to an exhibition at $5 for an adult and $2 for a child.
A family of 3 adults and 4 children visited the exhibition.
To Find :
What would be the charge if $50 note was used to buy the tickets.
Solution :
Charge of 3 adult ticket is, A = $( 5 × 3 ) = $15 .
Charge of 4 children ticket is, C = $( 4 × 2 ) = $8 .
Total amount to pay is :
T = $( 15 + 8 )
T = $23
Therefore, they get $( 50 - 23 ) = $27 change.

Courtney walks 1 mph slower than Brandi does. In the time that it takes Brandi to walk 6.5 mi, Courtney walks 5 mi. Find the speed of each person
Answer:
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Step-by-step explanation:
Let x = Courtney's walking speed
then
(x + 1) = Brandi's walking speed
:
Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time
6.5/x + 1 = 5/x
Cross multiply
6.5x= 5(x+1)
6.5x= 5x + 5
6.5x - 5x = 5
1.5x = 5
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
Note that:
(x + 1) = Brandi's walking speed
3.33mph + 1 = 4.33mph
Therefore,
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
The Courtney's walking speed = 3.33 mph. Brandi's walking speed = 4.33 mph.
We have given that,
[tex]6.5x - 5x = 5[/tex]
Courtney's walking speed = 3.33 mph
Brandi's walking speed = 4.33 mph
Let x = Courtney's walking speed
then (x + 1) = Brandi's walking speed
What is the formula time?Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time.
[tex]6.5/x + 1 = 5/x[/tex]
Cross multiply
[tex]6.5x= 5(x+1)[/tex]
Simplify parenthesis right side
[tex]6.5x= 5x + 5[/tex]
1.5x = 5
Isolate x.
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
(x + 1) = Brandi's walking speed
3.33 mph + 1 = 4.33 mph
Therefore,Courtney's walking speed = 3.33 mph
Brandi's walking speed = 4.33 mph

The equation m=40g gives the distance in miles, m, that a car can travel using g gallons of gas
a. If the car has gone 140 miles, how much gas was used
B. Write an equation the represents the inverse function
Answer:
3.5 gallons
Step-by-step explanation:
140=40g
140/40=g
a) The car used 3.5 gallons of gas
b) The inverse function is g=m/40
What is an inverse function?In mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) produces y, then putting y into the inverse of f(x) produces the output. A function that has an inverse is called invertible and the inverse is denoted by f⁻¹
Given here, distance = 140 and equation m=40g then using the equation we get
140 = 40 ×g
g= 3.5 gallons
and the inverse function is given by g = m/40
Hence the car uses 3.5 gallons and we found the inverse function is g=40/m

1/3
3/8
5/8
1/4
5/6
Answer: 2/3, 3/4, 5/8, 5/6
Step-by-step explanation:
First,
We must turn all of them into denominators that can be divided by 1/2.
2/3 = 4/6. 3 1/3 = 2/6
Now we see which is greater.
2/3 > 1/2.
3/4 > 1/2.
2/6 < 1/2.
1/3 < 1/2.
3/8 < 1/2.
5/8 > 1/2.
1/4 < 1/2.
5/6 > 1/2.
So the answers are 2/3, 3/4, 5/8, 5/6.
