Answer:
Last one: y = -6x-1
Step-by-step explanation:
If you graph the point (-1,5) and go down 6, right 1, the y-intercept will be at -1. That is what -1 represents. The slope of -6 is in the coefficient for x. Therefore, the answer is y = -6x - 1. Hope this helped.

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
A right triangle has one leg that measures 7 inches and another leg that measures 24 inches what is the area in square units of the triangle

is 40m, 50m, 60m a right triangle
The triangle with sides 40m, 50m, 60m is not a right angled triangle .
What is Pythagoras' theorem?Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
Pythagoras' theorem :
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
According to the question
Sides of triangle are 40m, 50m, 60m
As hypotenuses is the largest side
Applying Pythagoras' theorem
[tex]Hypotenuses ^{2} = Perpendicular^{2} + Base^{2}[/tex]
[tex]60 ^{2} = 40^{2} + 50^{2}[/tex]
3600 ≠ 1600 + 2500
3600 ≠ 4100
Hence, The triangle with sides 40m, 50m, 60m is not a right angled triangle ,

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.

numbers is 35. Find the numbers. *
a.) 7,28
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

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)
