The equation representing Main Street if Main Street passes through the point (5, 2) is; y = 2x - 8
How to find the equation in slope intercept form?
We are given the linear equation that represents 5th Avenue as;
y = 2x - 3
Now, main street is parallel to 5th avenue and as such will have the same slope.
Thus, equation of the line passing through (5, 2) representing main street is;
y - 2 = 2(x - 5)
y - 2 = 2x - 10
y = 2x - 10 + 2
y = 2x - 8

1. 60 high school seniors taking AP classes (advanced classes for college credit) were polled (asked a question) to see if they were taking European History or US History. A total Of 29 students said they were taking AP European History and a total of 50 students sald they were taking AP US History. How many students take both AP European History and AP US History? (Hint: Draw a venn diagram.)
The number of students take both AP European History and AP US History is 19 students
A Venn diagram is an illustration of the relationships between and among sets, groups of objects that share something in common.
Let the students take both AP European History and AP US History be x such that;
n(U) = 29 - x + 50 - x
If 60 high school seniors taking AP classes, then n(U) = 60. Substitute to have:
60 = 29 - x + x + 50 - x
60 = 79 - x
-x = 60 - 79
-x =-19
x = 19
Therefore the number of students take both AP European History and AP US History is 19 students

An executive invests 28,000 some at 7% and the rest at 4% annual interest if he receives an annual return of $1,570 how much is invested at each rate
we get that the amount invested at 7 % interest rate is $ 15,000 and at 4 % interest rate is $ 13,000.
We are given that:
the total amount invested is = $ 28,000
Let the amount invested at 7 % interest rate be x
Amount invested at 4 % interest rate = 28,000 - x
Interest received at the end of year = $ 1570
ATQ:
7 % x + 4 % ( 28,000 - x) = 1570
7 x + 4 (28,000 - x) = 157000
7 x + 112,000 - 4 x = 157,000
3 x = 157,000 - 112,000
3 x = 45,000
x = 45,000 / 3
x = 15,000
Amount invested at 7 % interest rate = x = $ 15,000
Amount invested at 4 % interest rate = 28,000 - x = $ 13,000

The solution to the system of equations is (2.5, -2)
How to determine the solution to the system of equations?The system of equations is given as:
2x + y = 3
2x - 5y = 15
Subtract the equations to eliminate the variable x
This is represented as
2x - 2x + y - -5y = 3 - 15
Evaluate the like terms in the above equation
So, we have
y + 5y = 3 - 15
Evaluate the like terms in the above equation
So, we have
6y = -12
Divide both sides of the above equation by 6
So, we have
y = -2
Substitute y = -2 in 2x + y = 3
2x - 2 = 3

The greatest angle in the given triangle is 104 degrees.
What is a triangle?The polygon with 3 sides, three vertices, and three angles is known as a triangle. A triangle's overall number of degrees is always 180 degrees.Given:
Let, the second angle has a measurement of x degrees.The first angle's measurement is 24 degrees greater than the second angle's measurement. As a result, the first angle is (24+x) degrees.The third angle is four times as large as the second. As a result, the third angle has a measure of 4x.So,
(24 + x) + x + 4x = 1806x = 124 - 486x = 156x = 156/6x = 26As a result, the second angle has a measurement of 26 degrees.
The first angle's measurement is now 24 degrees greater than the second angle's measurement.
Now,
= 24 + 26= 50As a result, the first angle has a measure of 50 degrees.

A spherical tank has a capacity of 750 gallons. using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (to the nearest hundredth of a foot).
The spherical tank with a capacity of 750 gallons has a radius of 2.88ft.
Volume refers to the total amount of space an object occupies. It also determines the capacity of the object.
Given the fact that 1 gallon is about 0.1337 ft^3, and the spherical tank has a capacity of 750 gallons, then it's volume or capacity can be converted from gallons to ft^3 by multiplying 750 with 0.1337.
1 gallon = 0.1337 ft^3
750 gallons = 750(0.1337 ft^3)
750 gallons = 100.275 ft^3
To solve for the radius of the spherical tank, use the formula for the volume of sphere given by the formula:
V = 4/3πr^3
where V = 100.275 ft^3
100.275 ft^3 = 4/3πr^3
r^3 = 23.93889288 ft^3

Please answer asap!!! Will give brainliest!!!!
Answer:
252
Step-by-step explanation:
One way we could think about this problem is by grouping the numbers together into pairs: -103+104 would be a pair, -105+106 would be a pair and et cetera up to the pair -199+200.
As you can see, each of these pairs add to 1 (-103+104=1, -199+200=1 etc.), so to solve this problem we can simply find how many of these pairs there are and multiply the number by 1 since each pair will total to 1.
To find how many pairs there are we need to find the number of numbers between 103 and 200 (incl.) and divide it by 2.
200-103= 97 numbers, adding 1 to count the one we started with gives us 98 numbers between 103 and 200 (incl.).
98/2 = 49 pairs of numbers. Since each pair totals 1, 1x49 is the total sum of all these pairs of numbers.
Now we need to address the other two numbers. The sequence started with 101+102 before we looked at the remaining pairs, so to find the sum, we just need to add together 101+102+49.
101+102+49 = 252

The absolute-value equation to find Jason's max and min speeds is |x| = |55 ± 5| mi/h and the maximum speed is 60 mi/h and the minimum speed is 50 mi/h.
Absolute Value equation:
An absolute value equation in the form | ax + b | has the following properties:
If c < 0 , | a x + b | = c has no solution .
If c = 0 , | a x + b | = c has one solution .
If c > 0 , | a x + b | = c has two solutions .
Given,
Jason is driving his car at 55mi/h he needs to keep his car within 5 mi/h of his current speed.
Here we need to write solve an absolute-value equation to find Jason's max and min speeds.
We know that, the current speed = 55 mi/h
And he want to keep the speeds within 5 mi/h of his current speed.
Let x be the unit that measure the maximum and minimum speed.
So,
The maximum speed.
|x| = 55 + 5 = 60 mi/h
and the minimum speed,
|x| = 55 - 5 = 50 mi/h

If they took in $5700, how many non-student tickets were sold?
Answer:
300 non student tickets were sold
Step-by-step explanation:
Let's solve the equation step by step,
In order to solve for how many non student tickets were sold, let's make an equation
5.50x + 8.00y = 5700 --------(equation 1)
x + y = 900 ---------------(equation 2)
Let's solve for x and y
5.5x+8y=5700;x+y=900
Rewrite equations:
x+y=900;5.5x+8y=5700
Step: Solve x+y=900 for x:
x+y=900
x+y+−y=900+−y(Add -y to both sides)
x=−y+900
Step: Substitute−y+900forxin5.5x+8y=5700:
5.5x+8y=5700
5.5(−y+900)+8y=5700
2.5y+4950=5700(Simplify both sides of the equation)
2.5y+4950+−4950=5700+−4950(Add -4950 to both sides)
2.5y=750
2.5y/2.5 = 750/2.5
(Divide both sides by 2.5)
