Answer:

2 and -3

Step-by-step explanation:

The reason why these are the answers is because if you put it in your graphics calculator then you can see the only points where the diagram intersects with the x-axis would be at points 2 and -3 :)

Answer:

Step-by-step explanation:

Going from (15/8,0) to (17/8,1/2), we see that x (the 'run') increases by 2/8, or 1/4, and that y (the 'rise') increases by 1/2.  Thus, the slope of this line through the given points is m = rise / run = (1/2) / (1/4) = 2.

Using the point-slope formula for the equation of a line, we obtain:

y - 0 = 2(x - 15/8), or

y = 2(x - 15/8) (simplest form), or

8y  = 2x - 15/4, or

2x - 8y = 15/4, or

8x - 32y = 15

All of these are correct; they are 'equivalent.'

Answer:

d) 34x^2 - 15x -25

( (8x + 5) * (8x - 5) ) - 5x(6x +3 )

= 64x^2 - 25 - 30x^2 - 15x

= 34x^2 - 15x - 25

28 is the number of tickets of the second prize

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation

Given that:

The first time wins = 60 tickets

The second time, she won a bonus, which was 4 times the number of tickets of the second prize

Altogether she won 200 tickets

Let N represent the number of tickets of the second prize

This can be written as:

60 + N + (4×N) = 200

60 + N + 4N = 200

60 + 5N = 200

5N = 200 -60

5N = 140

N = 140/5

N = 28

Therefore, the number of tickets of the second prize is 28

Answer:

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

Answer:

1.43

0.06

0.005

0.019

0.0075

Step-by-step explanation:

143% = 143/100 = 1 whole 43/100 = 1.43

6% = 6/100 = 3/50 = 0.06

1/2% = 0.5% = 0.5/100 = 1/200 = 0.005

1.9% = 1.9/100 = 19/1000 = 0.019

3/4% = 0.75/100 = 75/10000 = 3/400 = 0.0075

Answer:

You are now 38 m below base camp.

Step-by-step explanation:

Consider the provided information.

You start hiking at an elevation that is 80 meters below base camp.

Now your initial location is 80 m below base camp, that can be represents as: -80

Now you increase your elevation by 42.

So you go up by 42.

In other words, you get the equation -80+42 = -38.

Since a negative value is below the base camp, this means that you are now 38 m below base camp.

Answer:

$30+m($5 x h)

he will be working for 21 h

Step-by-step explanation:

So, Steve has $30, so you want to add that amount to the amount he earn, which is $105.

$5 times 21 is $105

h = 21

but we still need for m but, we already have m

m = $105

Step-by-step explanation:

I'm pretty sure all your answers are right except the second one. I'm no genus or anything like that tho so I'm not sure. Plus I'm not good at graphs. Well depends how it is.

Answer:

32y² + 192y

Step-by-step explanation:

First, we need to distribute 8y. This gets us 32y²+192y. I do not believe you can simplify that. I hope this helps!

Answer:

1 1/9 miles

Step-by-step explanation:

If john swims 5/12 of a mile in 3/8 of an hour, then;

5/12 miles = 3/8 hours

TO get the number of miles he swims in an hour, we will say;

x miles = 1 hour

Equating both expressions

5/12 miles = 3/8 hours

x miles = 1 hour

Cross multiply

3/8 x = 5/12

3x/8 = 5/12

3x * 12 = 5 * 8

36x = 40

x = 40/36

x = 10/9

x = 1 1/9

The amount he swims in an hour is 1 1/9 miles

Answer:

when x = 0.75, f(x) = 7 * 0.75 = 5.25

Answer:

Slope = -3/2

y-intercept = 3

Step-by-step explanation:

Select any two points.

(x₁ , y₁) = (0, 3)   & (x₂ , y₂) = (2 , 0)

Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

         [tex]\frac{0-3}{2-0}\\\\=\frac{-3}{2}[/tex]

y - y₁ = m(x -x₁)

y - 3 = [tex]\frac{-3}{2}(x - 0)[/tex]

y - 3 = [tex]\frac{-3}{2}x[/tex]

     [tex]y = \frac{-3}{2}x + 3[/tex]

Compare with y = mx + c

Slope = -3/2

y-intercept = 3

Answer:

1.Perpendicular

2. Parallel

3. Parallel

4.

Step-by-step explanation:

If two lines are parallel, slope is equal

If perpendicular, product of slopes is -1

y = mx + c is the general equation of a line form

m represents slope

1. slope is -1 and 1, they are perpendicular

2. Slope is 5 in both cases, they are parallel

3. slope is equal; equation ii is same as i if rewritten

They are parallel

4.

Greetings.

The answer is y = -2.

Explanation:

The equation is defined to solve for y-term. Our y is currently our subject at this point and needs to be solved.

We move -3 to another side and leave y as the subject of equation. Moving to another side will change the sign/operator to opposite.

Plus ---> Minus

Minus ---> Plus

Multiply ---> Divide

Divide ----> Multiply

[tex]y-3=-5\\y=-5+3\\y=-2[/tex]

Hope this helps! :)
