Solve as y=mx+b
Write an equation of the line below.

Solve As Y=mx+b Write An Equation Of The Line Below.

Answers

Answer 1

Answer:

y = 2x

Step-by-step explanation:

Since the line passes through the origin or (0,0), adding + 0 is irrelevant so we are just looking for slope.

Since there is a rise of 2 units every one unit, the slope or m = 2.

Since we know two points by observing the graph (0,0) and (3,6). m = y2-y1/x2-x1 = 6-0/3-0 = 6/3 = 2/1 = 2

Emily attends a Film Festival. The admission fee is $10. Each movie ticket cost $5 each. Emily wants to determine how many movie tickets she can buy if she has a total of $40 before she pays the admission fee.

Answers

Answer:

Emily can buy 6 movie tickets after paying the admission fee

Step-by-step explanation:

Let x be the number of movie tickets

If each movie ticket costs 5 dollars then the cost of x movies will be 5x

And the admission fee will be a constant.

She has $40 in total

So the equation can be written as

[tex]10+5x = 40\\5x = 40-10\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6[/tex]

Hence,

Emily can buy 6 movie tickets after paying the admission fee

What is the equation of a line that passes
through (0.5, 4.25) and (2, 18.5) and has a
y-intercept of -0.5

Answers

Answer:y=9.5x-0.5

Step-by-step explanation:

Ok, so you need to use the equation y2-y1/x2-x1 to find the slope. So (18.5-4.25)/(2-0.5) so 14.25/1.5 , calculate that and you get 9.5 which is your slope, apply that to the slope formula which is y=mx+b where (m) is slope and (b) is y intercept and you get y=9.5x-0.5

75% of the normal price of headphones is 45$. What's the normal price?

Answers

Answer:

60$ is the normal price.

Why:

Because if 45$ is 75%, then 30$ is 50%, 15 is 25%, and 0 is 0%. 50% + 50% = 100%. (That's how I did this one, anyway. This works on any 25%, 50%, or 75% problem.)

A card is randomly draw from a shuffled deck of cards and NOT REPLACED. A second card is drawn from the remaining shuffled cards. What is the approximate probability that both cards are RED?

Answers

The probability to draw a red card is 26 out of 52 cards, after the first card is drawn the probability of a new red card is 25 out of 51.

You have to multiply both probabilities because you want both events to happen.

P = (26x52)*(25x51)*100 = 24.5%

Solve 0 = 2y - 8x + 10 for y.

Answers

Answer:

y = 4x - 5

Step-by-step explanation:

move the 2y to the left side of the equation and move the 0 to the right side of the equation in which it becomes -2y = -8x+ 10 then divide the whole equation by -2 since y cannot be negative and have a coefficient. so then the equation becomes y = 4x - 5.

fisrt second and the third terms of proportion are respectively 7 , 14 and 25 . Find its fourth term​

Answers

Answer:

Check whether the two ratios form a proportion or not: (i) 6 : 8 and 12 : 16; (ii) 24 : 28 ... 3. The first, third and fourth terms of a proportion are 12, 8 and 14 respectively. ... 5. If a : b = 4 : 5 and b : c = 6 : 7; find a : c. Solution: a : b = 4 : 5. ⇒ a/b = 4/5.

Answer:

Let the fourth term be x

7/14=25/x

7x=14*25

x=350/7

x=50

Therefore the fourth term is 50

Provide an example of how a sales associate might communicate an idea for a new promotion to the company's marketing department. Read the excerpt from "An Image of Africa: Racism in Conrads Heart of Darkness.It might be contended, of course, that the attitude to the African in Heart of Darkness is not Conrad's but that of his fictional narrator, Marlow, and that far from endorsing it Conrad might indeed be holding it up to irony and criticism. Certainly, Conrad appears to go to considerable pains to set up layers of insulation between himself and the moral universe of his history. He has, for example, a narrator behind a narrator. The primary narrator is Marlow, but his account is given to us through the filter of a second, shadowy person. But if Conrad's intention is to draw a cordon sanitaire between himself and the moral and psychological malaise of his narrator, his care seems to me totally wasted because he neglects to hint, clearly and adequately, at an alternative frame of reference by which we may judge the actions and opinions of his characters. It would not have been beyond Conrad's power to make that provision if he had thought it necessary. Conrad seems to me to approve of Marlow, with only minor reservationsa fact reinforced by the similarities between their two careers.What is Achebes purpose in this passage? division property of equality 3n-5=-8(6+5n) The splitting apart of one cell to form two new cells is called ____meiosisfusionmitosis Gatsby asks the groundskeeper not to drain the pool.
