Step-by-step explanation:
Jimmy owns a small engine repair business. The revenue, in dollars, can be modeled by the equation y = 420 + 72x, where x is the number of hours spent repairing small engines. The overhead cost, in dollars, can be modeled by the equation y = 24x² + 180 where x is the number of hours spent repairing bikes. After about how many hours does the company break even? Note: The phrase break even refers to the value where the two functions are equivalent.
Answer:
5 hours
Step-by-step explanation:
Given
[tex]y = 420 + 72x[/tex] --- Revenue
[tex]y = 24x^2 + 180[/tex] --- Overhead cost
Required
Determine the hours for break even
To do this, we simply equate both expressions as follows:
[tex]24x^2 + 180 = 420 + 72x[/tex]
Collect Like Terms
[tex]24x^2 - 72x + 180 - 420 = 0[/tex]
[tex]24x^2 - 72x -240 = 0[/tex]
Divide through 24
[tex]x^2 - 3x - 10 = 0[/tex]
Expand:
[tex]x^2 -5x + 2x -10 = 0[/tex]
Factorize:
[tex]x(x -5) + 2(x -5) = 0[/tex]
[tex](x + 2)(x -5) = 0[/tex]
[tex]x + 2 = 0\ or\ x - 5 = 0[/tex]
[tex]x = -2\ or\ x = 5[/tex]
But x can't be negative because it represents time.
So, x = 5 hours
Layla opened a savings account and deposited 700.00 as principal the account earns 8%interest compounded annually what is the balance after 6 years
Answer:
The balance after 6 years is $1110.812026
Step-by-step explanation:
The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where
A is the new amountP is the initial amountr is the interest rate in decimaln is the number of periodst is the time in years∵ Layla opened a savings account and deposited $700.00 as principal.
∴ P = 700
∵ The account earns 8% interest compounded annually
∴ r = 8% = 8 ÷ 100 = 0.08
∴ n = 1 ⇒ compounded annually
∵ The time is 6 years
∴ t = 6
→ Substitute these values in the rule above
∵ A = 700[tex](1+\frac{0.08}{1})^{1(6)}[/tex]
∴ A = 700[tex](1.08)^{6}[/tex]
∴ A = 1110.812026
∴ The balance after 6 years is $1110.812026

2 _____________ 13.00
3 _____________ 19.50
Cost of package that weighs w pounds
If one pound = 6.50
2 pounds = 13.0
Then, the cost per pound = $6.50
Hence, cost of package that weighs w pounds will be ;
$6.50 * w = $6.50w

Step-by-step explanation:
у = 4х – 1
у = 2х – 5
How do you solve this, by using substitution?!
Answer:
x = -2, y = -9
Step-by-step explanation:
You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.
y = 2x -5 will become
4x - 1 = 2x - 5
Add 5 to both sides
4x + 4 = 2x
Subtract 4x from both sides
4 = -2x
Divide both sides by -2
-2 = x
Now we plug this number into an equation to find y.
y = 4x - 1 becomes
y = 4(-2) - 1
Simplifying it, we have:
y = -8 - 1
y = -9

When loaded with bricks, a lorry has a mass of 11600kg. If the mass of the bricks is three times that the mass of the empty lorry, find the mass of the bricks.
Answer:
8700kg
Step-by-step explanation:
lorry + bricks = 11600kg
bricks = 3(mass of empty lorry)
lorry mass is x
there for bricks = 3x
x+3x = 11600
4x =11600
x= 2900kg
mass of bricks = 3(2900)
=8700kg
Which statements verify that the solution set to |x + 3| < 5 is –8 < x < 2? Check all that apply. Substituting a value into the inequality from the solution set, such as –2, will create a true statement. Substituting a value into the inequality from the solution set, such as 1, will create a false statement. Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. Substituting any value into the inequality will create a true statement.
Answer:
First and fourth statements are correct
Step-by-step explanation:
The function is [tex]|x+3|<5[/tex] where the domain is [tex]-8<x<2[/tex]
[tex]|-2+3|=1<5[/tex]
The first statement is correct.
[tex]|1+3|=4<5[/tex]
Substituting a value into the inequality from the solution set, such as 1, will create a false statement. This is wrong as it creates a true statement.
[tex]|4+3|=7\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 4, will create a true statement. This is wrong as a value which is not from the solution set will create a false statement.
[tex]|6+3|=9\nless 5[/tex]
Substituting a value into the inequality not from the solution set, such as 6, will create a false statement. This is correct.
[tex]|10+3|=13\nless 5[/tex]
Substituting any value into the inequality will create a true statement. This is wrong as the value of x must be in the solution set.
Answer:
1.) Substituting a value into the inequality from the solution set, such as –2, will create a true statement.
4.) Substituting a value into the inequality not from the solution set, such as 6, will create a false statement.

enter your answer and show all the steps that you use to solve this problem in the space provided. −→ g i bisects ∠ d g h so that m ∠ d g i is x − 3 and m ∠ i g h is 2 x − 13 . find the value of x.
So the value of x is 10
Given that line GI bisects angle DGH so that the measurement of angle DGI is x-3 and the measurement of angle IGH is 2x-13.
Since GI bisects that means the angle is cut into 2 equal angles or
DGI = IGH
Bisect means to cut into two even halves. If you bisect a 90 degree angle you create two 45 degree angles,
So by bisection
x - 3 = 2x - 13
Solving for x
13 - 3 = 2x - x
10 = x
or
x = 10
Therefore the value of x is 10.

Mr. Roy was creating bundles for his classes. He had 20 pencils, 80 pens and 55 markers.
He wanted each bundle to contain the same number of pencils, pens and markers.
a) What is the largest number of bundles he could create without any left over?
Answer:
The largest number of bundles he could create without any left over is 5.
Each bundle to contain 4 pencils, 16 pens and 11 markers
Step-by-step explanation:
Pencils = 20
Pens = 80
Markers = 55
a) What is the largest number of bundles he could create without any left over?
Find the highest common multiple of 20, 80 and 55
20 = 1, 2, 4, 5, 10, 20
80 = 1, 2, 4, 5, 8, 10, 16, 20......
55 = 1, 5, 11, 55
The highest common multiple of 20, 80 and 50 is 5
Pencils = 20 / 5
= 4
Pens = 80 / 5
= 16
Markers = 55 / 5
= 11
The largest number of bundles he could create without any left over is 5.
Each bundle to contain 4 pencils, 16 pens and 11 markers
