Complete question :
Christelle and Larkin both drive customers on the weekend. Christelle charges a flat fee of $4, plus $1 per mile. Larkin charges a flat fee of $2, plus $1.25 per mile.
Which equations represent each of their earnings, (y), after a given number of miles, (x)?
Select two that apply. Put more then one answer
y=4x+4
y=x+4
y=2x+1.25
y=1.25x+2
y=−x−4
y=1.25x−2
Answer:
y=x+4
y=1.25x + 2
Step-by-step explanation:
Christelle:
Flat fee = $4
Charge per mile = $1
Earning, y after x miles
y = 4 + x
Lakin:
Flat fee = $2
Charhe per mile = $1.25
EEarning, y after x miles
y = 2 + 1.25x

Rose would be saving 50 dollars after 10 months. At first Rose only had $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.
Write the equation of the line that passes through the point (1,5) and has a slope of -2.
Answer:
y = -2x + 7
Step-by-step explanation:
to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis
a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)
so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)
now, an equation for a line is written as Y = MX + B
M = slope
B = y intercept
our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation
y = -2x + 7
Answer:
y= -2x + 7

order from least to greatest 1/3, 5/12/, 1/6, 0.25
answer:
1/6, 0.25, 1/3, 5/12
step-by-step explanation:
whenever i have to order fractions least to greatest, i put them in decimal form. so 1/3 into a decimal would be 0.3333333; 5/12 into a decimal would be 0.4166666; 1/6 would be 0.1666666; and 0.25 is already a decimal. so it'd be 1/6, 0.25, 1/3, 5/12

When substituting y = 5x + 12 into the equation 3x - 2y - 32 = 0 to solve the
system, Jun determines that the value of y is
- a negative fraction only
- a positive fraction only
- a negative integer
- a positive integer
Answer:
A negative integer
Step-by-step explanation:
3x - 2(5x+12) - 32 = 0
3x - 10x - 24 - 32 = 0
-7x -56 = 0
-7x = 56, x = -8
y = 5(-8) + 12, y = -28

3/5k - 5 = 7/10k HURRY
Answer:
k = -7Step-by-step explanation:
Given the expression
3/5k - 5 = 7/10k
We are to find the value of k
Cross multiply
3(10k) = 7(5k-5)
30k = 25k - 35
30k - 25k = -35
5k = -35
k = -35/5
k = -7
Hence the value of k is -7
The line AB is shown on the grid.
b)Find the equation of the line
perpendicular to AB and passing
through the midpoint of AB.
Step-by-step explanation:
a)
first step: find the gradient slope of line AB
A(-1,-2) B(7,2)
gradient=change in y/change in x
M=[2-(-2)]/[7-(-1)
M=4/8
M=1/2
the gradient of the straight line is given by
M1*M2=-1
1/2*M2=-1
multiply both sides by the reciprocal of 1/2
2*1/2*M2=-1*2
M2= -2.
b)
first find the mind point of line AB
A(-1,-2) B(7,2)
M.P=(x1+x2)/2 ,(y+y2)/2
M.P=(-1+7)/2 ,(-2+2)/2
M.P=6/2 ,0/2
M.P=3,0
ALSO THE GRADIENT PERPENDICULAR TO LINE AB IS;
M= -2
equation of a line perpendicular to AB and passes through the midpoint of AB
Y-Y1=M(X-X1). (3,0). M=-2
y-0=-2(x-3)
y= -2x+6

please answer the slope of this graph
Answer:
The slope of the line = m = 2
Step-by-step explanation:
Taking two points from the line graph
(0, 0)(1, 2)Determining the slope between (0, 0) and (1, 2)
(x₁, y₁) = (0, 0)(x₂, y₂) = (1, 2)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 0] / [1 - 0]
= 2 / 1
= 2
Thus, the slope of the line = m = 2
what is the slope of this graph? it has to be simplified.

Evaluate the function if x=-3
f(x) =1/2x-1
A. -2.5
B. 0.5
C. -4
D. -1
Answer:
A) -2.5
Step-by-step explanation:
You have to plug the x-value into the function.
f(x) = (1/2)x - 1
f(x) = 1/2(-3) - 1
f(x) = (-3/2) - 1
f(x) = -1.5-1
f(x) = -2.5
What is the value of x?
All 3 sides of the triangle are identical so each interior angle is 60 degrees.
7x + 4 = 60
Subtract 4 from both sides:
7x = 56
Divide both sides by 7:
x = 8

Mr. Gregson packs ornaments into boxes. Each box holds eight ornaments. Which representation displays the relationship between x, the number of boxes packed, and y, the number of ornaments packed?
Answer:
y = 8x
Step-by-step explanation:
Given that :
Ornanment are packed in boxes
Number of ornament per box = 8
x = number of boxes packed
y = Number of ornaments
Number of Ornanments packed = (Number ornaments per box * number of boxes packed
y = 8 * x
y = 8x
A 12-foot ladder is leaning against a wall. The distance from the base of the wall to the base of the ladder is 6 StartRoot 2 EndRoot feet. Given this information, what can be determined about the triangle formed by the ground, wall, and ladder? Check all that apply. The triangle is isosceles. The leg-to-hypotenuse ratio is 1:StartRoot 2 EndRoot. The leg-to-hypotenuse ratio is 1:StartFraction StartRoot 2 EndRoot Over 2 EndRoot. The nonright angles are congruent. The ladder represents the longest length in the triangle.
Answer:
The leg-to-hypotenuse ratio is 1/√2
The ladder represents the longest length in the triangle.
Step-by-step explanation:
The set up in the question will b a right angled triangle
Length of the ladder will be the hypotenuse
The distance from the base of the wall to the base of the ladder is the adjacent
Height of the wall will be the opposite
Note that the longest side is always the hypotenuse (length of the ladder)
Given
length of the ladder = 12foot
The distance from the base of the wall to the base of the ladder = 6√2
The ratio of leg to hypotenuse = 6√2/12 = √2/2
√2/2 = √2/2 * √2/√2
√2/2 = √4/2√2
√2/2 = 2/2√2
√2/2 = 1/√2
Hence the leg-to-hypotenuse ratio is 1/√2
From the calculation the following are correct:
the leg-to-hypotenuse ratio is 1/√2
The ladder represents the longest length in the triangle.
Answer:
The leg-to-hypotenuse ratio is 1/√2
The ladder represents the longest length in the triangle.

What would be the equation of a line that passes through (3,-7), with a slope of -4/3?
What is the slope-intercept equation of this line? A. y=-2x+6 B. y=2x+6 C.y=-1/2x+6 D.y=6x-2
Answer:
y = [tex]-\frac{4}{3}[/tex]x + 6
Step-by-step explanation:
y = mx + b
m: slope
b: y-intercept
y-intercept point on the graph is (0, 6) because it's the point that's on the y-axis.
Therefore, y-intercept is 6.
Slope: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Point A: (0, 6)
Point B: (4, -2)
Slope (m) = [tex]\frac{-2 - 6}{4 - -2}[/tex]
[tex]m = \frac{-2 - 6}{4 +2}[/tex]
[tex]m = \frac{-8}{6}[/tex]
[tex]m = -\frac{4}{3}[/tex]
y = [tex]-\frac{4}{3}[/tex]x + 6
