If you use the FOIL method this will be a breeze.

Check the picture below.

sure, since y = 0 is a line, in essence the x-axis really, that goes to infinity, so we can draw an infinite amount of perpendicular lines on it all the way.

The equation for a line perpendicular to the line y=0 is x=a, where a is the x-coordinate of the point where the line intersects the x-axis. There are infinitely many lines that are perpendicular to the line y=0. For example, the line x=3.

The equation for a line perpendicular to the line y=0 is simply the equation for a vertical line passing through any point on the x-axis. A vertical line is defined by the equation x = a, where a is the x-coordinate of the point where the line intersects the x-axis.

Since the line y=0 is also the x-axis, any vertical line passing through a point on the x-axis will be perpendicular to it. Therefore, there are infinitely many lines that are perpendicular to the line y=0.

For example, the equation for a line perpendicular to y=0 passing through the point (3,0) would be x=3.

Answer:

$ 159.95

Step-by-step explanation:

139.95 x 19 = 2,659.05 In total the 19 clarinets = $ 2,659.05

$ 4,578.45 - $ 2,659.05 = $ 1919.40 In toal the 12 trumpets are = $ 1,919.40

$ 1,919.40 ÷ 12 = $ 159.95 The trumpets cost $ 159.95 each.

Hope this helps you out : )

If the music store sold 12 trumoets and 19 clarinets last month and clariners sell for $139.95 and the store made $4,578.45. The price of a trumpet is $159.95.

Let's denote the price of a trumpet as "t" dollars.

The revenue from trumpet sales would be 12 times the price of a trumpet (12t) and the revenue from clarinet sales would be 19 times the price of a clarinet ($139.95):

Revenue from trumpets + Revenue from clarinets = Total revenue

12t + 19 * $139.95 = $4578.45

Now solve for the price of a trumpet (t):

12t + 19 * $139.95 = $4578.45

12t + $2659.05 = $4578.45

12t = $4578.45 - $2659.05

12t = $1919.4

t = $1919.4 / 12

t ≈ $159.95

Therefore the price of a trumpet is $159.95.

Answer:

Step-by-step explanation:

So 10.55$ for an hour at the ice-cream store, and he works 8 hours.

So 8 * 10.55$ because he earns 10.55$ eight times, since he works 8 hours;

then, you would get $84.40 for a week at the ice-cream store.

Now he earns 13.85$ per hour at the movie theater, for a total of 7 hours.

Again, 13.85$ * 7 since he earns 13.85$ 7 times (7 hours); he gets $96.95 for a week at the movie theater.

1. so we want to know how much does mike earn a week, which basically means how much money did he earn in total during the week working at two jobs?

so you just add what you calculated, you get $181.35 in total.

2. So we want to know how much he has left after 22 percent of the total amount of money that he earned is taken away, due to taxes.

So we want to know how much is 22 percent of the total, so $181.35 * 22% = $39.89

So now we know that $39.89 is 22 percent of the total amount ($181.35), and we know that it is taken away from us, so we subtract $39.89 from $181.35, and you would get $141.46.

So, $141.46 is the amount of money left for Mike after paying his taxes.

3. So we want to know which jobs pays him more before paying the taxes. According to the first question, he earns $84.40 a week at the ice cream store, and $96.95 a week at the movie theater. So, obviously the movie theater pays him more.

It has two questions in one, and the second question asks how much more does the higher paying job pays than the lower paying one. So they're asking what is the difference between the two prices?

So we need to subtract $96.95 (the higher paying one) - $84.40 (the lower paying one), and you would get $12.55.

So, the movie theater pays Mike $12.55 more dollars than the ice cream store.

This response provides the equations for three lines that all pass through the point (-3, 4). Line p's equation is identified as y = 4x + 16, the equation for perpendicular line q is y = -1/4x + 5.75, and the equation for the horizontal line r, which only traverses Quadrants 1 and 2, is y = 4.

The subject of your question is related to

Algebra of Straight Lines

, specifically, writing equations of lines that pass through a specific point (-3,4), and have certain slopes or orientations.

Let's start by examining line p which passes through the point (-3,4) and has a slope of 4. Using the point slope form of linear equation, we have y - y1 = m(x - x1). Substituting the given values, we get y - 4 = 4(x + 3) which simplifies to y = 4x + 16. This is the equation for line p.

The line q is perpendicular to line p, so its slope is the negative reciprocal of the slope of p, which is -1/4. Using point slope form of linear equation and substitifying the slope and point, we get y - 4 = -1/4(x + 3) which simplifies to y = -1/4x + 5.75. This is the equation for line q.

The line r is a little bit tricky since it's only mentioned to pass through Quadrants 1 and 2. This implies that the slope of r is 0, making line r horizontal. Because it passes through y=4, its equation is simply y = 4.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side).

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

The subject of this question is Mathematics, particularly dealing with the concept of least common multiple (LCM). The question is asking when will Lauren visit the park and the library on the same day again. Given that Lauren goes to the park every 3 days and the library every 10 days, the day when she'll do both again is the least common multiple of 3 and 10.

The least common multiple (LCM) is the smallest multiple that is exactly divisible by every member of a set of numbers. In this case, we need to determine the LCM of 3 and 10. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ... The multiples of 10 are 10, 20, 30, 40, .... As we can see, the smallest number that appears in both lists is 30.

Answer:

$3,113,34

Step-by-step explanation:

The formula for calculating compound interest is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where

A=the future total value, i.e, the money you will have after t years.

P=the initial deposit.

r=the annual interest rate.

n=the number of times that interest is compounded per year.

t=the number of years the money is saved.

In our case

A is unknown and we will have to calculate it with the formula.

P=$12,000

r=2.9%=0.029

n=365 because the interest is compounded daily and there are 365 days in a year

t=8 years

Applying the formula we get

[tex]A=12,000(1+\frac{0.029}{365})^{365\times8}[/tex]

[tex]A=12,000(1+\frac{0.029}{365})^{2,920}[/tex]

[tex]A=12,000(1.000079)^{2,920}[/tex]

So A=15,113.336

This is the amount of money you would have after 8 years.

Subtracting the initial deposit from this amount we obtain the interest earned I

I=15,113.336-12,000=3,113.336

Rounded to the nearest hundreth

I=$3,113,30

Step-by-step explanation:

the fastest time would be Malik at 11.84

followed by Marcell, Bryson then Wyatt

Malik had the fastest time in the 100 meter sprint with a time of 11.84 seconds.

To determine who had the fastest time in the 100 meter sprint, we simply need to compare the times listed for each athlete. In sprinting, the fastest time is the lowest numerical value, as it indicates the athlete completed the distance in the shortest amount of time.

Here are the times presented in the question:

Bryson - 12.14 s

Malik - 11.84 s

Marcell - 11.94 s

Wyatt - 12.44 s

Upon comparing the times, we can see that Malik had the fastest time with 11.84 seconds. Therefore, Malik is the athlete who completed the 100 meter sprint the quickest in this group.
