Answer:72
Step-by-step explanation:
4x - 2y = 5 if the range is {-5,-3,0,7}
The domain of the given function given range is {1.25, -0.25, 1.25, 4.75}
Domain and range of a functionThe range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f(x) make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of value.
Given the range of the function as {-5, -3, 0, 7}
Determine the domain from the function 4x - 2y = 5
4x - 2y = 5
4x - 2(-5) =5
4x + 10 = 5
4x = 5
x = 5/4 = 1.25
If y = -3
4x - 2y = 5
4x - 2(-3) =5
4x + 6 = 5
4x = -1
x = -1/4 = -0.25
If y = 0
4x - 2(0) =5
4x - 0 = 5
4x = 5
x = 5/4 = 1.25
If x = 7;
4x - 2y = 5
4x - 2(7) =5
4x - 14 = 5
4x = 19
x = 19/4 = 4.75
Therefore the equivalent domain of the function is {1.25, -0.25, 1.25, 4.75}

I need help if you don't mind. I have to graph the linear equation using intercepts.
We want to find the places where the line
2x - 3y = 12
intercepts y-axis and x- axis
y- interceptWhen the line intercepts y axis, we know that x=0, we replace it in the equation so we can find y value:
2x - 3y = 12
↓
2 · 0 - 3y = 12
↓
0 - 3y = 12
-3y = 12
y = 12 / -3
y = -4
x - interceptIn the same way, we find the interception with x- axis when y = 0. We find the value of x replacing y by 0 in the equation:
2x - 3y = 12
↓
2x - 3 · 0 = 12
↓
2x - 0 = 12
2x=12
x = 12 / 2
x = 6
GraphWe locate both points: y = -4 and x = 6:
Finally, we join the points with a straight line
Help please! Some friends go to an amusement park in one car. They must pay a 6.00 parking fee plus 29.99 per person for tickets. The algebraic equation is C=6.00+29.99. Use the equation to calculate the number of tickets purchased for the group if the total cost was 215.93. Show all work
Answer:
7 # there were 7 people in the group
Step-by-step explanation:
C = 6.00 + 29.99x # the equation given
215.93 = 6.00 + 29.99x # 215.93 is the total so substitute it for C. Now we solve for x
209.93 = 29.99x # We subtracted 6 from both sides
7 = x # We divided 29.99 from both sides

What does it mean (to the process of finding all factors) that I have found 2 PRIME factors as a factor pair?
Answer:
It means that you are done.
Step-by-step explanation:
When you are trying to find factors of a number or an algebraic expression, you must keep on factoring until you have all PRIME factors. PRIME factors cannot be further factored. So that means you are done factoring.
example: (a number)
6
factors: 2 and 3
2 and 3 are prime they can't be factored anymore so you have completely factored 6.
example: 20
factors: 4 and 5
5 is prime but 4 is not, so you can factor it more.
4 is 2×2
So 20 factored is 2×2×5
Or algebra example:
Factor x^4 - 81
factors: x^2 - 9 and x^2 + 9
x^2 + 9 cannot be factored more (prime) but x^2-9 can. Its x-3 and x+3.
Find the value of x in each case.

determine a, the cost of the labor per hour.
Answer:
3.75x + $119 = $400.25
x = $75
Step-by-step explanation:
Lauren needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3.75 hours and charged her $119 for parts. The total was $400.25. Write and solve an equation which can be used to determine a, the cost of the labor per hour.
3.75x + parts = $400.25
so:
3.75x + $119 = $400.25
subtract $119 from both sides:
3.75x + $119 - $119 = $400.25 - $119
3.75x = $281.85
divide both sides by 3.75
3.75x/3.75 = $281.85/3.75
x = $75
so the tech charged $75 per hour.
The shortest side of a right triangle measures 5, and the longest side measures 13. Determine the measurement of the unknown side.
Using the Pythagorean Theorem formula, the measurement of the unknown side (base) is 12 units.
How can the measurement of the unknown side of a right triangle be determined?According to the Pythagorean Theorem formula, c² = √a²+b², where c = hypotenuse, a = perpendicular, and b = base.
The hypotenuse is the longest side of a right triangle.
The shortest side is the perpendicular (adjacent side) while the other side is the base (opposite side).
Since the hypotenuse is given as equal to the square root of perpendicular squared and the base squared, we can compute the base, unknown side, using the following Pythagorean Theorem formula.
c² = √a²+b²
The perpendicular (shortest side) of a right triangle = 5
The hypotenuse (longest side) = 13
c² = √a²+b²
169 = √5²+b²
169 = √25 + b²
The base (unknown side):
b² = 169 - 25
b² = 144
The square root of √144 = 12
b = 12
Thus, the unknown side of the right triangle is the base, measuring 12 units.

The right triangle's hypotenuse (longest side) = 13 units
According to the Pythagorean Theorem,
H² = P² + B², Where H = hypotenuse, P = perpendicular, and B = base.
As per the given question, here H = 13 and P = 5
Substitute the values of H = 13 and P = 5 in the Pythagorean Theorem,
(13)² = (5)²+ B²
169 = 25 + B²
B² = 169 - 25
B² = 144
B = √144
B = 12 units
Therefore, the length of the unknown side is 12 units,

Tom’s car has 11 1/9 gallons of gas. If he uses 38 of the gas, how much gas does the car have left?
Answer: 6 [tex]\frac{17}{18}[/tex] gallons of gas left in the car
Step-by-step explanation:
Upon further clarification, this question reads "3/8 of the gas" and not "38 of the gas."
If Tom's car has 11 1/9 gallons of gas, and we want to know how much gas the car will have left if he uses 3/8 of that, we first need to find 3/8 of 11 1/9.
"Of" can usually be written as multiplication.
3/8 of 11 1/9 = 3/8 * 11 1/9 = 4 1/6
Next, we will use subtraction since he uses 4 1/6 gallons of gas.
11 1/9 - 4 1/6 = 6 17/18 gallons

The correct answer for the given problem is option (D) .
growth rate in the initial population of 1.08.. So, the equation for solving this population growth problem is 10,000(1.08) ²⁰
Before twenty years, the actual population was 10,000.
Population growth per year = 8% = ((100+8)10,000)/100=10,800.
