Albert needs $133 to buy a new hard drive. He earns $4.75 for each car he washes. If he spends $19 in supplies, write and solve an equation to find the number of cars he needs to wash to reach his goal.
Answer:
Albert needs 32 cars to wash to reach his goal.
Step-by-step explanation:
We know that the slope-intercept form of a linear function is
[tex]y = mx+b[/tex]
where m is the slope or rate of change and b is the y-intercept
It is stated that Albert needs $133 to buy a new hard drive.
Let 'y' be the amount Albert needs.As earns $4.75 for each car he washes. Thus, $4.75 the rate of change or slope will be.
As he spends $19 on supplies. Since it is an expense, so -19 is basically the y-intercept 'b'.
Let 'x' be the number of cars he needs to wash to reach his goal.
Thus, substituting the value m = 4.75, y = 133, and b=-19 in the slope-intercept form of a linear function
y = mx+b
133 = 4.75x - 19
133+19 = 4.75x
152 = 4.75x
x = 152 / 4.75
x = 32
Therefore, Albert needs 32 cars to wash to reach his goal.
Marlene expects her gross income to be $54,000 this year, and she expects her required deductions to amount to $15,000. Her employer covers 90% of the cost of a $4800-per-year health insurance plan and 80% of the cost of a $900-per-year life insurance plan, with the remainder of the cost coming out of Marlene's pay, and Marlene also expects to contribute 8% of her gross income this year to her 401(k) plan. She wants to calculate how much she will receive for each of her bimonthly paychecks.
Answer:
Marlene will receive $1,417.50 for each of her bimonthly paychecks.
Step-by-step explanation:
This can be calculated using the following 3 steps:
Step 1: Calculation of annual deductions to bear by Marlene
Required deductions = $15,000
Contribution to cost of health insurance plan per-year = $4800 * 10% = $480
Contribution to cost of life insurance plan per-year = $900 * 20% = $180
Contribution to this year's 401(k) plan = $54,000 * 8% = $4,320
Step 2: Calculation of annual paychecks
Annual paychecks = Gross income - Required deductions - Contribution to cost of health insurance plan per-year - Contribution to cost of life insurance plan per-year - Contribution to this year's 401(k) plan = $54,000 - $15,000 - $480 - $180 - $4,320 = $34,020
Step 3: Calculation of bimonthly paychecks
Bimonthly paychecks = Annual paychecks / 24 = $34,020 / 24 = $1,417.50
Therefore, Marlene will receive $1,417.50 for each of her bimonthly paychecks.

Write an expression to represent the expenses of the fundraiser in the following paragraph.
The varsity basketball team is selling t-shirts as a fundraiser. It costs them $100 to have the shirts professionally designed, and they have to pay $5 for each shirt. They plan on selling the shirts for $10 each.
Answer:
5x-10x+100 or a simplified version: -5x+100 where x is the number of shirts
Step-by-step explanation:
5x is for every shirt they have to pay for and it adds to the cost
-10x is for every shirt they sell which decreases the total cost
100 is for the upfront cost of having the shirts professionally designed

green 20
yellow 40
blue 10
What is the relative frequency of choosing a red duck? What color of duck is there likely to be the most of in the pool?
A.
The relative frequency is 0.3. It is likely that most ducks are blue.
B.
The relative frequency is 0.2. It is likely that most ducks are yellow.
C.
The relative frequency is 0.3. It is likely that most ducks are yellow.
D.
The relative frequency is 0.2. It is likely that most ducks are green.
Answer:
C
Step-by-step explanation:
Red is 30, so 30/100 or 0.3

Given the interval notation, choose the correct graph.
Answer:
A.
or
4.
Step-by-step explanation:
In the equation y=mx, how do you find m on a graph?
Answer:
m is the slope of the equation y=mx+b. TO find the slope you look at the y intercept of the graph, b, and from that point find how much up/down and to the right/left you need to go. For example from point 0, 4, the y intercept, to another point on the graph (any point on the line would work) 2, 8 , I need to go up 4 units and to the right 2 units. The slope is 4/2 or just 2.'
If this is too confusing just find two points on the line in a graph and folow this equation: y2-y1 / x2-x1
where y2 is the y value of the second point, y1 is the y value of the first point, x1 is the x value of the first point and x2 is the value of x in the second point
Step-by-step explanation:
Answer:
In the equation y=mx+b, m is the slope. The formula for slope is [tex]\frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex], so to solve find any two points on the graph and plug them into the formula. You could also count the difference, remember that slope is the change in y over the change in x. For example, if y increases by 3 units and x increases by 2 units then the slope is 3/2.
Which is the better deal: $3.15 for 10 apples or $4.10 for 11 apples?
Answer:
3.15 for 10 is the better deal
Step-by-step explanation:
This is because $3.15 for 10 apples is worth 32 cents per apple. On the other hand, $4.10 for 11 apples is worth 37 cents per apple. And even though you're getting more apples it is costing you more per apple.

Determine whether KM and ST are parallel, perpendicular, or neither.
K (-3, -7), M(3, -3), S(0, 4), T(6, -5)
Answer:
So, KM and ST are perpendicular lines
Step-by-step explanation:
Find the slope of KM and ST.
K (-3, -7), M(3, -3)
Slope of KM = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{-3-[-7]}{3-[-3]}\\\\= \frac{-3+7}{3+3}\\\\ = \frac{4}{6}\\\\= \frac{2}{3}[/tex]
S(0 , 4) & T(6 , -5)
Slope of ST = [tex]\frac{-5-4}{6-0}[/tex]
[tex]=\frac{-9}{6}\\\\=\frac{-3}{2}[/tex]
Slope of KM * slope of ST = [tex]\frac{2}{3} * \frac{-3}{2}[/tex]
= -1
So, KM and ST are perpendicular lines
Answer:
perpendicular

the lines whose equations are 2x + 3y = 4 and y = mx + 6 will be perpendicular when
Answer:
These lines will be perpendicular when m = ³⁄₂
Step-by-step explanation:
Two lines are perpendicular when the product of their gradients equal to -1. So:
m₁ * m₂ = -1
Let's get the first equation in gradient-intercept form (same as equation two).
2x + 3y = 4
3y = -2x + 4
y = -⅔x + ⁴⁄₃
We know the first gradient, and now we can find the gradient of the second line (which when multiplied will result in -1 as these lines are perpendicular). So:
-⅔ * m₂ = -1
m₂ = ³⁄₂

Hometown Cable has the 'Triple Play' package. It offers a land line. Internet service, and cable TV for one fixed price. If you already subscribe to their cell phone service, they offer and additional 12% off the price of the 'Triple Play' package. If the DISCOUNTED price of the 'Triple Play' package is $132, what is the price of the package WITHOUT the discount? (Hint: What % of the original price is the discounted price?)
Answer:
the price of the package without the discount is $150
Step-by-step explanation:
The computation of the price of the package without the discount is shown below:
Let us assume the price without discount be x
So after discount it would be x - 0.12x = 0.88x
Now the equation would be
0.88x = $132
x = $132 ÷ 0.88
= $150
hence, the price of the package without the discount is $150
We simply applied the above formula so that the correct value could come
And, the same is to be considered
What is the answer for 2[7d-(5)(1.05)]?
Answer:
14d-10.50
Step-by-step explanation:
clear the brackets by putting an invisible one in front for example: (5)= 1 x 5, then simplify the like terms example: -5 + 1.05 = -3.95 ( it's a positive sign because the invisible one in front of the (1.05) is positive), then do the distributive law for example: 2( 7d - 3.95) is equal to 14d-10.50
