determine whether the ordered pair (8,-5) is a solution to the equation 3x-2y=6

Answers

Answer 1

So, to solve this, you just plop those x and y values into the equation. So:

3(8) -2(-5)= 6
24- (-10) =6
34=6
34=/=6
Since these two are not equal, the ordered pair is not a solution.

calculate the rise and run to find the slope of each line

Answers

First you count UP/ DOWN how many units until you get to the point the dot is at. For the first one, your rise (by counting up) is 4. Than you count to the side (your run) to the dot. This would be 2. So your slope is 4/2. Which is equal to 2/1. 2/1 equals 2. So your slope is 2.

The first one 2 and the second one is 4/-5

Question 15

Leo bought a bulldozer for $63,103. The value of the bulldozer depreciated at a constant rate per year. The table below shows the value of the bulldozer after the first and second years:

Year
1
2
Value (in dollars)
58,054.76
53,410.38

Which function best represents the value of the bulldozer after t years?

f(t) = 58,054.76(0.92)t
f(t) = 63,103(0.08)t
f(t) = 63,103(0.92)t
f(t) = 58,054.76(0.08)t

Answers

The function is
f(1) = 63,103(0.92)^1
F (1)=58054.76
Solve for r (rate of depreciation)
58054.76=63103 (r)^1
Divide both sides by 63103
R=58,054.76÷63,103
R=0.92 rate of depreciation

So the function best represents the value of the bulldozer after t years is
f(t) = 63,103(0.92)t

Hope it helps!

Answer:

c f(t) = 63,103(0.92)t

Step-by-step explanation:

At the end of a party, 3/4 cup of dip is left. Jim divides 4/5 of the leftover dip equally between 2 friends. How much dip does each friend get?

Answers

Final answer:

Each friend gets 3/10 cup of dip.

Explanation:

To calculate how much dip each friend gets, we first need to find the amount of dip Jim had after dividing.

Since 3/4 cup of dip was left and Jim divided 4/5 of that dip, we can calculate it as follows:

Amount of dip Jim divided = (3/4) * (4/5) = 3/5 cup

Since there are 2 friends, we divide the amount of dip Jim divided equally:

Amount of dip each friend gets = (3/5) / 2 = 3/10 cup

Therefore, each friend gets 3/10 cup of dip.

are the given lines parallel y=-5 y=3 ? how do you know? ASAP TY

Answers

Yes, the given lines are parallel as the value for x is both cases is equal to 0.

Final answer:

The lines y = -5 and y = 3 are parallel because they are both horizontal lines with a slope of 0. This is the same case with lines Y2 and Y3 from the reference provided; they are parallel because they share the same slope.

Explanation:

The lines y = -5 and y = 3 are indeed parallel lines. This is because they are both horizontal lines, which means their slopes are both 0. In mathematics, two lines are parallel if and only if their slopes are equal. In the case of these two lines, since they do not have a variable component (x), they are straight horizontal lines, meaning their slopes are equal and thus, they are parallel.

To illustrate this, contrast it with the given lines in the reference; line Y2 = -173.5+ 4.83x − 2(16.4), and line Y3 = -173.5+ 4.83x + 2(16.4), whereby y = -173.5+ 4.83x is the line of best fit. Y2 and Y3 have the same slope, which shows these lines are also parallel as they share the same inclination and distance apart at all points.

= final answer 3.5

Answer: 3.5

Step-by-step explanation: In order to write [tex]\frac{35}{10}[/tex] as a decimal, we need to find a fraction that is equivalent to [tex]\frac{35}{10}[/tex] with a 100 in the denominator. Notice that if we multiply the numerator and denominator of [tex]\frac{35}{10}[/tex] by 10, we get the equivalent fraction [tex]\frac{350}{100}[/tex] which we can now write as a decimal. Remember that the hundredths place is two places to the right of the decimal point. Therefore, we can write [texfrac{350}{100}[/tex] as 3.5.

You and two friends are playing basketball. You make 7 out of 15 shots. Your first friend makes 6 out of 10 shots and your second friend makes 5 out of 12 shots. Who is the better shooter? How would you solve this problem using what you know about rational numbers?

Answers

First, you will need to find the percentage of shots made for each person, or you can find the least common denominator. This is because it makes it easier to see how the numbers compare to each other in size. You can find the percentage of shots made by looking at how many shots a person made and dividing it by the total shots that person made, which us the denominator. Then, you would take the decimal and move it two places to the right. Once you find the percentages of all three people, you can then compare the percentages to each other. In this case, the higher the percentage, the better the shooter that person is.

For the proportional relationship y = -5x, what is the ratio of vertical change to horizontal change? Will the graph of the line increase or decrease? A. -51 The graph increases from left to right. B. -50 The graph increases from left to right. C. -51 The graph decreases from left to right. D. -50 The graph decreases from left to right.

Answers

The given proportional relationship is y = -5x.
Therefore the ratio
y/x = -5 = -5/1

If x changes by 1, then y/x = y/1 = -5.
This means that y changes by -5 when x changes by 1.
The ratio of vertical change is -5:1

The standard equation for a straight line is
y = m*x + c
where
m = the slope,
c = the y-intercept.

Therefore the given relationship is a straight line with a negative slope of -5. This means that y decreases as x increases.

Answer: C
