Find the x and y intercepts of the graph of the linear equation -x + 8y = 4
Answer: x-int: (-4, 0), y-int: (0, 1/2)
Step-by-step explanation:
x-int: when y = 0
-x + 8*0 = 4
-x = 4
x = -4
(-4, 0)
y-int: when x = 0
0 + 8y = 4
8y = 4
y = 1/2
(0, 1/2)

hope this help :)
Answer:
[tex]\boxed {x = -19}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]-4(x + 1) - 3 = -3(x - 4)[/tex]
-Use Distributive Property to both sides of the equation:
[tex]-4(x + 1) - 3 = -3(x - 4)[/tex]
[tex]-4x - 4 - 3 = -3x + 12[/tex]
-Combine like terms:
[tex]-4x - 4 - 3 = -3x + 12[/tex]
[tex]-4x - 7 = -3x + 12[/tex]
-Take [tex]-3x[/tex] and add it to [tex]-4x[/tex]:
[tex]-4x - 7 + 3x = -3x + 3x + 12[/tex]
[tex]-x - 7 = 12[/tex]
-Add both sides by [tex]7[/tex]:
[tex]-x - 7 + 7 = 12 + 7[/tex]
[tex]-x = 19[/tex]
-To make the variable [tex]x[/tex] positive, divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} = \frac{19}{-1}[/tex]
[tex]\boxed {x = -19}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-19[/tex].

A local clothing store sells t-shirts for $8 each, sweaters for $12 each, jeans for $15 each. Let x represent the number of t-shirts sold, y represents the number of sweaters sold, and z represent the number of jeans sold. Write an expression to represent the total amount of sales from t-shirts, sweaters, and jeans
Answer:
8x + 12y + 15z
Step-by-step explanation:
Given the sales rate of three items: 8$ for t-shirts, 12$ for sweaters, and 15$ for jeans. It also states that these rates are represented by the corresponding variables being x for t-shirts, y for sweaters, and z for jeans.
To complete the expression, just combine the rate with the corresponding variables. i.e 8$ for t-shirts, and x for shirts = 8x, 12$ for sweaters and y for sweaters = 12y, 15$ for jeans, and z for jeans = 15z. Finally, sum them together.
8x + 12y + 15z

Which function is a horizontal translation of the parent quadratic function, f(x) = x2
O A. ;(z) = x2 - 4
B. g(x) = (x - 4)
C. k(x) = -42
D. h(x) = 4,2
The function that represents the horizontal translation of the parent function is (b)g(x) = (x - 4)^2
How to determine the horizontal translation?The function is given as:
f(x) = x^2
An horizontal translation is represented using:
f'(x) = (x ± h)^2
Where h does not equal to 0
From the list of options. we have:
g(x) = (x - 4)^2
Hence, a function that represents the horizontal translation of the parent function is (b)g(x) = (x - 4)^2

A map’s scale is 1 inch: 3.5 miles. If the actual distance between two places is 77 miles, then they will be ____ inches away from each other on the map.
==================================
Work Shown:
(1 inch)/(3.5 miles) = (x inches)/(77 miles)
1/3.5 = x/77
1*77 = 3.5*x ..... cross multiply
77 = 3.5x
3.5x = 77
x = 77/3.5
x = 22
22 inches on paper correspond to 77 miles in real life.

How many 9-inch ribbons can be cut from 112yards of ribbon? show work
Answer:
448 ribbons
Step-by-step explanation:
in order to find this, you need to convert the yards into inches. there are 36 inches is a yard (a yard is 3 feet and one foot is 12 inches ) so you would multiply 112 and 36 to find the total number of inches it woulde be. 112x36=4,032. Now that you know the total number of inches, divide it by 9 to find the total number of ribbions you can make.
4,032/9= 448
so you could make a total of 448 ribbons

Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 How much did Hans pay for his trip?
Given :
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile.
In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 .....1)
To Find :
How much did Hans pay for his trip.
Solution :
x = 450 miles.
Putting value of x in equation 1 we get :
y = $(0.17×450 + 15.89)
y = $(76.5+15.89)
y = $92.39
Therefore, Hans will pay $92.39 for his trip.
Hence, this is the required solution.

Evaluate the function for x = 3 * f(x) = x2 – 2x + 6 O x=9 O x = 6 O x=21 O x = 4
Answer:
When you input values for x, you can determine a single output for y. ... f(x)= 4x + 1 is written in function notation and is read “f of x equals 4x plus 1. ... perimeter, P = 4s, as the function p(x) = 4x, and the formula for area, A = x2, as a(x) = x2. ... in both cases, you substitute 2 for x, multiply it by 4 and add 1, simplifying to get 9
