Compare Jennifer and William's bank accounts
Jennifer's bank account is modeled by the following equation where x equals the number of weeks and f(x) equals the total balance
f(x) = 8x + 30
William's bank account balances after weekly deposits are showing in the following table:
How much money was in Jennifer's account when it was opened?
Answers
Answer:
If x represents the number of weeks for Jennifer, plug in 0 for x since we want to know the balance when it was opened.
So, 8(0)+30=f(x).
0+30=f(x)
30=f(x)

1. Suppose Leif can rake his entire yard in 2.5 hours, while his younger sister, Autumn, can do it in 4 hours by herself. How many minutes will it take the two of the to rake the entire yard if they are working together, to the nearest whole number? Please answer in a number of minutes.
2. Once Leif and Autumn have all of the leaves in their yard in a huge pile, they decide to do a little math with their pile of leaves. They notice that all of the leaves are yellow and/or red. So, they decide that Leif will count the leaves with any red (5550 leaves) and Autumn will count the leaves with any yellow (6820 leaves). Then, they get their other little brother, Oakie, to come out and count the leaves that have both yellow and red on them (4370 leaves). Using their reported numbers, how many leaves are in the pile? Please just provide the number of leaves.
3. Leif bets Autumn that she can't reach into the middle of the pile and pull out three leaves with yellow on them in her first three picks, without replacement. Assuming the different kinds of leaves were all mixed up together again and randomly distributed throughout the pile, what is the probability that she will be successful? Express your answer as a decimal to the nearest hundredth.

Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8 a car, to raise more money. Tony solved the inequality 8x + 200 Greater-than-or-equal-to 500, and determined that if they wash 37 cars, they will have enough money. Is he correct? Explain.
Answers
Answer:
No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5. Since the class must wash a whole number of cars, they need to wash at least 38 cars.

After _____months, there will be_______ of each type of caregiver
Answers
After 3 months, there will be 12 of each type of caregiver
How to illustrate the equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Since the daycare center in Seaside currently has 9 assistant caregivers and 6 senior caregivers. Since demand is high, the owner is going to be hiring 1 assistant caregiver per month and 2 senior caregivers per month.
This will be:
9 + m = 6 + 2m
where m= number of months
Collect the like terms
2m - m = 9 - 6
m = 3
The number of caregiver will be:
9 + m
9 + 3

Write the component form of the vector that translates P(4,5) to P'(-3,7)
Answers
Answer:
The component form of the vector is v = -7·i + 2·j
Step-by-step explanation:
The given parameters are;
The coordinates of the initial point = P(4, 5)
The coordinates of the point after the translation by the vector, v = P'(-3, 7)
Therefore, we have;
The horizontal component of the vector, vₓ = (-3) - 4 = -7
The vertical component of the vector, [tex]v_y[/tex] = 7 - 5 = 2
The magnitude of the translation, v = √([tex]v_y[/tex]² + vₓ²) = √((-7)² + 2²) = √53 ≈ 7.28
Therefore, the component form of the vector, v, is given as follows;
v = vₓ·i + [tex]v_y[/tex]·j
Substituting the known values of vₓ and [tex]v_y[/tex] gives;
v = -7·i + 2·j
The component form of the vector is v = -7·i + 2·j.

Dan plans to use $10 less than three-fourths of his allowance to buy a new video game. If the purchase price of the game is $50 how much is his allowance?
plz I really really need help
Answers
Answer:
$80
Step-by-step explanation:
So the game costs 10 less then 3/4ths
Find 3/4ths by adding 10 to 50.
60=3/4
Divide both sides by 3
20= 1/4
Multiply by 4
80= 4/4
80= 1 allowance
Answer: $80
Step-by-step explanation:
First you would take the $10 and add it to $50 to make three-fourths of his allowance. That would give us $60 and 60 divided by 3 would be 20. Then we would add $20 to $60 and give us his allowance which would be $80. Hope this helps!

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given table is
x 0 2 3 4
y -2 0 1 2
The slope is m=2-4/1-3=-2/-2=1
m=1
y intercept is 2=4+b
b=-2
Hence, y=x-2 is the function represents the relationship between x and y.

Use a proportion to find the missing side length in the following similar figures. Please help me understand and figure out how to solve this question. Thank You! :)
Answers
Answer:
x = 4.5 m ⇒ A
Step-by-step explanation:
The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal
In the given figure
∵ The two triangles are similar
∵ 2 m and x are corresponding sides
∵ 4 m and 9 m are corresponding sides
∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]
→ By using cross multiplication
∴ x × 4 = 2 × 9
∴ 4x = 18
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]
∴ x = 4.5 m
