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.

The gazelle football team made 5 plays, gaining 4 yards on each play . then they made 4 plays, loosing 10 yards on each play . What was the total change in their positions from where they started ?

Answers

-20. 5×4=20. 4× (-10)=-40

20 + (-40)= -20

Final answer:

The gazelle football team gained 20 yards initially and then lost 40 yards, resulting in a total change in position of -20 yards, ending up 20 yards behind their starting point.

Explanation:

The total change in position for the gazelle football team is determined by the yardage gained and lost during the different plays. Initially, the team gains 4 yards on each of 5 plays, which totals to 4 yards/play × 5 plays = 20 yards gained.

Then, the team loses 10 yards on each of 4 plays, which totals to 10 yards/play × 4 plays = 40 yards lost. To find the overall change in position, we subtract the yardage lost from the yardage gained: 20 yards gained - 40 yards lost = -20 yards.

Therefore, the total change in position from where they started is -20 yards, meaning that they ended up 20 yards behind where they started.

Aiden weighs 39 pounds less than his older brother, Jacob. Jacob weighs more than 100 pounds. what could be the weight of the Two brothers?

Answers

We can determine that Jacob's weight is any number greater than 100 pounds, and Aiden weighs 39 pounds less than Jacob. Without an exact weight for Jacob, we cannot provide precise weights, only a possible range for both brothers.

To solve the question regarding Aiden and Jacob's weight, we can set up a simple algebraic equation. If Aiden weighs 39 pounds less than Jacob, and Jacob weighs more than 100 pounds, we can use variables to represent their weights.

Let's let J represent Jacob's weight. Therefore, Aiden's weight is J - 39 pounds. We're told that Jacob weighs more than 100 pounds, so J > 100.

For example, if Jacob weighed 110 pounds (which is more than 100 pounds), then Aiden would weigh 110 - 39 = 71 pounds. However, since we don't have an exact weight for Jacob, we cannot determine the exact weights but we can provide a range. Jacob's weight is any number greater than 100 and Aiden's weight is always 39 pounds less than Jacob's weight.

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

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
-5:1
The graph decreases from left to right.

A car travels at a constant speed. What is the car's speed between checkpoints, expressed as a unit rate? Use the information given in the picture.

Answers

44 mph

208-120= 88
88/2 = 44

Answer:

The unit rate is 44 miles per hour.

Step-by-step explanation:

The difference between both the checkpoints is given by:

[tex]208-120=88[/tex] miles driven

Time taken to travel 88 miles = [tex]3-1=2[/tex] hours

As the car travels at a constant speed, so we get 88 miles driven in 2 hours.

Hence, per hour distance covered is = [tex]\frac{88}{2}=44[/tex] miles per hour.

To find the value of x, we use the quadratic formula on the equation x² + 0.00088x - 0.000484 = 0, resulting in two possible values for x, with the positive value being the valid solution in real-life contexts. In chemical equilibrium problems, the positive value is used to further calculate important quantities like pH.

Explanation:

To find the value of x, we use the quadratic formula. Given the equation x² + 0.00088x - 0.000484 = 0, we can calculate the values for x that satisfy the equation. After applying the quadratic formula, we find two possible values for x, which are x = -0.0024 or x = 0.00139. However, in a real-life context, such as a chemical equilibrium problem, a negative concentration does not make sense. Therefore, we can disregard the negative value and conclude that x actually equals 0.00139.

In problems where x represents a concentration, once we've determined x = 0.0021, we could use this to calculate the concentration of H3O+, which would allow us to find the pH of the solution by plugging this concentration into the pH equation.

When defining what x represents, such as in a statistical context where we might be interested in the number of students who do their homework on time, x would be defined differently. It is essential to understand the context of a problem to accurately determine what x signifies and how to solve for it.

Hello! The equation that would be used to solve this problem is 25.59 = 9.99 + 0.05m. To find out how many minutes Shelly used for the month, let’s subtract 9.99 from both sides. When we do, we get 15.6 = 0.05m. Now, divide each side by 0.05 to isolate the “m”. When we do that, we get 312. Shelly used 312 minutes in a month. m = 312.

A company rents out 15 food booths and 20 game booths at the county fair. The fee for a food booth is $100 plus $5 per day. The fee for a game booth is $50 plus $7 per day. The fair lasts for 'd' days, and all the booths are rented for the entire time. Write and simplify an expression for the amount in dollars the the company is paid.

Answers

105 times 15= 1575
57 times 20= 1140 
1140+1575= 2715 

(2715)(d)= x 

x being the total amount the company paid
- Food booth

From the sentences above, we can see that people need to pay $ 100 as intial payment, and additional $5 for each day they use the booth. Since he company has 15 food booths, the expression would bey

y = 15  (100 + 5d)
in which y = total amount that company received and d is the number of days the booth is rented

- Game Booth

From the sentences above, we can see that people need to pay $ 50 as intial payment, and additional $7 for each day they use the booth. Since he company has 20 game booths, the expression would be

y = 20 (50 + 7d)
in which y = total amount that company received and d is the number of days the booth is rented


- For both game booths and food booths

y    = [15 ( 100 + 5d)  ]      +        [ 20 (50 + 7d)]

y = 1500 + 75d+ 1000 +140d

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.
