I AM PAYING 50 POINTS AND BRAINLIEST FOR THE ANSWER AND EXPLANATION FOR THIS QUESTION!!!
The county fair charges $1.25 per tickets for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables
(b) Write a linear equation that can be used to determine the cost for anyone who only ride tickets and fair admission.
(c) Explain your answer to Part B.
(a) the variables are the prices of the the tickets for the rides, and the total cost.
(b) y = 1.25x + 12.50
(c) 43.75 (total spent) = 1.25(cost per ticket)(25)(total spent) + b (fair admission)
1.25 times 25 = 31.25
43.75 - 31.25 = b (12.50)
y = 1.25x + 12.50

write in slope intercept form (-1,3) (1,-2)
Answer:
y = 5/2x + 1/2
Step-by-step explanation:
Find the slope with the formula [ y2-y1/x2-x1 ].
-2-3/1-(-1)
-5/2
undefined
Find the y-intercept using the formula for slope-intercept form [ y = mx + b ]
y = -5/2x + b
3 = -5/2(-1) + b
3 = 5/2 + b
1/2 = b
Put everything we solved for into its final form.
y = 5/2x + 1/2
Best of Luck!
Answer:
y = -2.5x + 0.5
Step-by-step explanation:
First we must find the slope.
To do so we will use this formula:
y2 - y1 / x2 - x1
Substitute with (-1, 3) and (1, -2)
-2 - 3 / 1 + 1
-5/2
-2.5 is our slope.
Now to put this into slope-intercept form we will use Point-slope formula.
y - y1 = m(x - x1)
substitute using the ordered pair, (-1, 3):
y - 3 = -2.5(x + 1)
Distribute:
y - 3 = -2.5x + -2.5
Add 3 to both sides:
y = -2.5 + 0.5
Double check by using the other ordered pair.
(1, -2)
y + 2 = -2.5(x - 1)
Distribute:
y + 2 = -2.5x - 2.5
Add 2 to both sides:
y = -2.5x + 0.5
(-1, 3) and (1, -2) written in slope intercept form is:
y = -2.5x + 0.5

What is the correct factorization of:
x? - 11x + 18
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)
if a pair of standard dice are rolled what is the probability that the sum will be less that 5
Answer:
1/6
Step-by-step explanation:
Acellus sux
The probability of the pair of standard dice to be rolled and for their sum to be less than 5 is [tex]\frac{1}{6}[/tex]
What is probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
According to the given problem,
The possible rolls can be represented by ordered pairs,
Where the first entry is the outcome of one die and the second is the outcome of the other.
(1 and 1) , (1 and 2) ,…….,(1 and 6), (2 and 1), (2 and 2),.......,(2 and 6),.....,(6 and 1) ,(6 and 2),....,(6 and 6).
There are 36 possible outcomes when two dice are rolled.
Pairs having sum less than 5: (1 and 1) ,(1 and 2) , (1 and 3) , (2 and 1) , (2 and 2), (3 and 1).
The probability that the sum is less than 5 = [tex]\frac{6}{36}[/tex]
= [tex]\frac{1}{6}[/tex]
Hence, we can conclude, there is a probability of [tex]\frac{1}{6}[/tex] for the standard dice to be rolled and for their sum to be less than 5.

7. Bobby wants to check if (4,2) is on the line y = 5x - 18. Lisa also wants to check if (3,-3) is on the
same
line. Show your work, and write a statement (sentence) about who's point is on the line. (8 pts)
Answer:
Both Bobby's and Lisa's points are on the line.
Step-by-step explanation:
You just have to plug the points into the equation.
Bobby:
(4,2)
2 = 5(4) - 18
2 = 20 - 18
2 = 2
Lisa:
(3,-3)
-3 = 5(3) - 18
-3 = 15 - 18
-3 = -3
So they both are correct.

Solve 0.25x + 7 = 1/5 x -8
Answer:
x= -300
Step-by-step explanation:
0.25x+7 = 1/5x-8
convert the decimal into a fraction
1/4x+7 = 1/5x-8
1/4x+7+8 = 1/5x
1/4+15 = 1/5x
multiply both sides of the equation by 20
1/4x(20)+15(20) = 1/5x(20)
5x+300 = 4x
5x-4x+300 = 0
x+300 = 0
x = -300

b.) 9,26
c.) 13.5, 21.5
d.) 13.5, 35
Answer:
Step-by-step explanation:
Givens
smaller number = x
Larger number = 2x + 8
Sum = 35
Equation
x + 2x + 8 = 35
Solution
3x + 8 = 35
3x = 35 - 8
3x = 27
x = 9
The smaller number = 9
The larger number = 2*9 + 8 = 26
