Which of the following represents an equation of a line parallel to one whose equation is 2x + 8x = 18

Answers

Answer:

y=-4x+3

Step-by-step explanation:

it does not show the equations that are following

but the main thing you need to know is that when two lines are parallel they have the same slope

and do you mean 2x+8y=18 not x?

edit:

answer choices: y=-4x+3, y=8x-2, y=4x+7, y=-8x+9

2y+8x=18

first change that equation to slope intercept form to find the slope

2y = -8x+18 -> y = -4x+9

slope is -4

so the answer is y=-4x+3 because it also has a slope of -4

What additional information would allow the triangles to be proven similar by AA?
Question options:

A)



B)



C)

∠M ≅ ∠P

D)

∠Q ≅ ∠P

Answers

The additional information would allow the triangles to be proven similar by AA is: C. ∠M ≅ ∠P.

What is the AA Similarity Theorem?

The acronym, "AA" stands for "angle-angle". Thus, the AA similarity theorem is a triangle theorem that is used to prove that two triangles that have two pairs of corresponding congruent angles are similar to each other.

The figure given shows two triangles, triangle MNO and triangle PQR, which have a pair of corresponding congruent angles, angle MNO and angle PQR [both are congruent because they are right angles that are equal to angle 90 degrees.]

Thus, this is not enough to prove that both triangles are similar to each other by the AA similarity theorem.

In other to prove that both triangles are similar by AA, we need to be given or shown that both triangles also have another pair of corresponding congruent angles.

Thus, the additional information needed can be: C. ∠M ≅ ∠P.

Find the distance travelled by a vehicle in 10 seconds when it travels at the uniform speed of 72kmh​

Answers

Answer:

If the initial velocity being is a straight line, and the final velocity being 0 km/hr, or o m/s, then:

v(final) = v(initial) + at

0 = 72 Km/h + (-=a * 10 s)

- a * 10 s = 72 km/hr * hr/3600s * 1000m/km = 20m/s

a = - (20 m/s) / (10 s)

a = - 2 m/s^2

A system of linear equations can be used to determine on which day the cost to park is the same for both lots. One of the equations in the
system is y=6x. What is the other equation in the system?

Answers

Answer:

y = 4x + 12

Step-by-step explanation:

Hey there,

For Lot A I found the slope to be 4/1. You can do this by picking two points and finding the change in y over the change in x, or you can just look at the graph and realize that to get from one y variable to the other you're adding 4 and to get from one x variable to the other you're adding one. That means it's equal to 4/1 which is the same thing as 4. We know that at 1 the cost is $16. The y-intercept has to be equal to 12, meaning that they started off with $12 and are gaining $4 every day.

I hope this helps :)

The last table is the answer

Step-by-step explanation:

The last table has a constant slope of -3, hence it represents a linear function.

Table of functions

From the given table, we need to determine which of the table is a linear table.

To determine that, we must check which of the table has a constant rate of change

Looking at the last table;

Slope = -4-(-2)/2-1
Slope = -4+1/1

Slope = -3

Since the last table has a constant slope of -3, hence it represents a linear function.

The PTA is holding a raffle. The prize is a camera worth $55000. Each raffle ticket costs $2. 29 tickets are sold and a winner is drawn at random. Find the expected value of the purchase of a ticket.

Answers

Answer: $1,894.55

Step-by-step explanation:

The expected value is the sum of the different outcomes multiplied by the probability that that particular outcome comes true.

Probability of winning = 1/29 tickets

Probability of losing = 28/29 tickets

Gain if you win

= Price - cost of tickets

= 55,000 - 2

= $54,998

Loss if lose:

= -$2

Expected value = (Probability of winning * gain if you win) + (Prob. of losing * loss)

= (1/29 * 54,998) + (28/29 * -2)

= $1,894.55
