Which of the following inequalities matches the graph?
A) The correct inequality is not listed.
B) 5x + y ≥ 1
C) 5x + y ≤ 1
D) 5x − y ≥ 1
Answer:
D)
Step-by-step explanation:
Line: y = 5x - 1
The shaded space is less than or equal to the line.
So it is y [tex]\leq[/tex] 5x - 1

Jon earns $4 for delivering groceries and $2 for each delivery he makes.
How much money will he earn if he delivers to five houses?
Answer:
$14
Step-by-step explanation:
ok so since he is delivering groceries he gets $4.
now when he delivers he get $2 more, so for each house he delivers to he adds $2 to that $4.
so the easiest was to do this is 5x2.
5x2 is 10.
now $10 is how much more he gets on top of the $4, so now we need to add the $4 to the $10.
your answer is $14

What is the slope of the equation: x + 2y = 6
Write a function g whose graph represents the indicated transformation of the graph of F. Let g be a translation 4 units down and a horizontal shrink by a factor of of the graph of f(x) = x.
Answer:
g(x) = 6x+4
Step-by-step explanation:
The given function f(x)=x
Let p(x) be an intermediate function after translation of f(x).
So, after the translation 4 unit down, the new function
p(x) = f(x) - 4
p(x) = x-4
Now, there is a horizontal shrink by a factor of 6, so the required function g(x) is
g(x) = p(6x) [here 6 is the horizontal shrink factor]
g(x) = 6x-4
Hence, the required function is g(x) = 6x+4
Write the equation, 3x+7=2(3-y) in function form.
Answer:
The function of the equation is f(x) = [tex]-\frac{1}{2}[/tex] [tex]-\frac{3}{2}[/tex] x
Step-by-step explanation:
The function form of the linear equation is f(x) = m x + b, where
m is the slope of the line represents the graph of the functionb is the y-intercept∵ The equation is 3x + 7 = 2(3 - y)
→ Simplify the right side by multiplying the bracket by 2
∵ 3x + 7 = 2(3) - 2(y)
∴ 3x + 7 = 6 - 2y
→ Add 2y for both sides
∵ 2y + 3x + 7 = 6 - 2y + 2y
∴ 2y + 3x + 7 = 6
→ Subtract 7 from both sides
∵ 2y + 3x + 7 - 7 = 6 - 7
∴ 2y + 3x = -1
→ Subtract 3x from both sides
∵ 2y + 3x - 3x = -1 - 3x
∴ 2y = -1 - 3x
→ Divide each term by 2
∴ y = [tex]-\frac{1}{2}[/tex] - [tex]\frac{3}{2}[/tex] x
→ Replace y by f(x)
∴ f(x) = [tex]-\frac{1}{2}[/tex] [tex]-\frac{3}{2}[/tex] x
∴ The function of the equation is f(x) = [tex]-\frac{1}{2}[/tex] [tex]-\frac{3}{2}[/tex] x

Answer:
1/512
Step-by-step explanation:
The probability is 2 out of 2^10 , because there are only two sequences when same result (heads or tails) shows twice in a row exactly once in the ten tosses (HTHTHTHTHT and THTHTHTHTH) out of 2^10 possible sequences.

Lennox owns a big apple orchard. She ships her apples to various markets using a fleet of trucks. Every week, each truck goes on 3 trips, and for each trip, Lennox gets 300 dollars. On a single trip, a truck delivers 50 packs, and each pack contains 12 kilograms of apples. Overall, Lennox sells 4500 dollars worth of apples in a week.
How much does Lennox get for a single kilogram of apples?
____________dollars per kilogram
Answer:
$0.50 per kilogram
Step-by-step explanation:
($300/trip)/(50 packs/trip) = $6/pack
($6/pack)/(12 kilograms/pack) = $0.50/kilogram
Complete the description of the slope of the line that joins the points
positive
negative
0
undefined
Answer:
The slope of the line that joins the points is negative.
i.e m = -6/5
Step-by-step explanation:
Taking two points from the graph to determine the slope
(-3, 4)(2, -2)Finding the slope between (-3, 4),(2, -2)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]'
[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(2,\:-2\right)[/tex]
[tex]m=\frac{-2-4}{2-\left(-3\right)}[/tex]
[tex]m=-\frac{6}{5}[/tex]
Therefore, the slope of the line that joins the points is negative.
i.e m = -6/5

A number line going from negative 2 to positive 2 in increments of 1. There are 4 equal spaces between each number.
Answer:
Please check the number line attached below.
Step-by-step explanation:
Please check the attached graph below.
The line graph is representing that a number line:
Going from negative 2 to positive 2 in increments of 1. There are 4 equal spaces between each number.From the graph, it is clear that the point 0 is taken as arbitrary. The left side number units from 0 represent the negative values and the right-sided number units from 0 represent the positive values.
When we move on the right side from the 0, the numbers increase and when you move on the right side from the 0, the number decreases.
Answer:
The number line shows -2 through 2, divided into fourths, with zero in the middle. The numbers increase as you move right and decrease as you move left.

2x - 3y --24
x + 6y = 18
Substitution
Answer:
y=12
x=30
Step-by-step explanation:
2x-3y=24 ... 1
x+6y=18 ... 2
2*2:
2x+12y=36...3
3-1:
y=12
x=30
When the following system of equations 2x - 3y = -24 and x + 6y = 18 are solved, the value of x and y is found to be -6 and -4 respectively.
Mathematically, an equation is a statement that asserts the equivalency of two expressions. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by an equal sign( =). The LHS and RHS can be numbers, variables, constants, or further complex fine expressions.
Given the system of equations:
2x - 3y = -24 (equation1)
x + 6y = 18 (equation2)
From equation 2,
x = 18 - 6y
Now, substitute this expression for x in equation (1):
2(18 - 6y) - 3y = -24
36 - 12y - 3y = -24
36 - 15y = -24
-15y = -60
y = [tex]\frac{(-60)}{(-15)}[/tex]
y = 4.
Now substitute it back into equation (2) to solve for x:
x + 6(4) = 18
x + 24 = 18
x = 18 - 24
x = -6
Therefore, the solution to the system of equations is x = -6 and y = 4.

Answer: 22
Step-by-step explanation:
From the question the, we are informed that members of a lacrosse team raised $1352.50 to go to a tournament and that they rented a bus for $802.50 and budgeted $25 per player for meals.
The equation which can be used to determine p, the number of players the team can bring to the tournament would be calculated as:
802.50 + 25p = 1352.50
25p = 1352.50 - 802.50
25p = 550
p = 550/25
p = 22
They can bring 22 players to the tournament
