(3,1) and (w,9); slope = -8/3
W= ?

Answers

Answer 1

Answer:

w=0

Step-by-step explanation:

We know a point (3,1) and the slope (-8/3), so we can use point-slope form, which is y-y1=m(x-x1)

For reference, y1 is the y in the point, m is the slope, and x1 is the x in the point

So we subsitute it

y-1=-8/3(x-3)

do distributive prop.

y-1=-8/3x+8

add 1 to both sides

y=-8/3x+9

This is the equation of the line.

Now to find w, which is the x value.

The point will pass through line, so we can susbtitute the point into the equation.

9=-8/3x+9

subtract 9 from both sides

0=-8/3x

multiply by -3/8 on both sides (the reciprocal of -8/3), we need to isolate x

0=x

x=w

therefore, w=0

Hope this helps!

I’m not sure how the chart works but here’s how to solve the problem.

First creat two inequalities with the values given using x as the number of student ticked and y as non student.

X + y = 292 tickets

Notice how this measures only the tickets

The next equation is the cost and total earnings.

1x + 3y = $470

Notice these values are in dollars not tickets.

Now pick one equation and solve for one variable. We will use the x variable and the first equation.

X + y = 292

Get x by itself to find the equality by subtracting y from both sides.

X = 292 - y

Now we have a value for x that we can use to solve the second equation. Plug the right side of the equation in for the x value since they are equal

1(292-y) + 3y = 470

Now solve for y

292 - y + 3y = 470

2y + 292 = 470

2y = 178

Y = 89$

Now use this value for y in the second equation again.

X + 3(89) = 470

X + 267 = 470

X = 203$

This means that student ticket sales totals 203$ while non student totals 89$

In this specific case this also means that:

Student tickets sold = 203 tickets
Non student tickets sold = 89 tickets

Answers

Answer:

1. last choice

2. first choice

Step-by-step explanation:

First Image

The reason why it is the last choice because when times keep going as distance also keeps increasing as well. But the last choice says that run at the end of track then turn around and run back. That means there must be a decreasing distance and a maximum value as well.

Therefore the only with max point/vertex is the absolute value which matches the last choice.

Second Image

First choice because the car straight forwards without any change. The car runs with a steady speed but the distance will keep changing without any change of distance.

So the answer is first choice.
