what is the equation for the line that passes through the given point and is parallel to the graph of y=2/3x+19; (-9, 4)​

Answers

Answer:

Step-by-step explanation:

We're given the line

[tex]y = \frac{2}{3}(x) + 19[/tex]

The slope of the line is [tex]\frac{2}{3}[/tex]

We have to find another line with the same slope that goes through the point

[tex](-9, 4)[/tex]. We can solve this by using

[tex]y = mx + b\\y = \frac{2}{3}(x) + b\\4 = \frac{2(-9)}{3} + b\\4 = -6+ b\\b = 10\\\\y = \frac{2}{3}(x) + 10[/tex]

Which expression means the same as "subtract 3 from 7 and then multiply
by 4"?

Answers

(7-3)4 or (7-3)x4 :)

Answer:

(7-3)x4

Step-by-step explanation:

Youre subtracting 3 from 7 so that means that 7 is first because your subtracting 3 and seven is the greater number, it says to then multiply by 4 so that means that you have to put parenthesis around 7-3 because you need to do them first. I hope this makes sense and answers your question! :)

Which of the following could be the equation of a line parallel to the line y = 4 ?

A- undefined
B- y=0
C- x=4
D- y=4x

Answers

Answer:

B

Step-by-step explanation:

y = 4 is a horizontal line parallel to the x- axis

A parallel line must also be horizontal with equation

y = c ( c is the value of the y- coordinates the line passes through )

The only equation in this form is

y = 0 ( the equation of the x- axis ) → B

Option B: [tex]y=0[/tex] is the equation of the line parallel to the line [tex]y=4[/tex]

The general equation of a line is [tex]y=mx+b[/tex] where, [tex]'m'[/tex] is the slope of the line and [tex]'b'[/tex] is the constant.

For a line to be parallel with the line [tex]y=4[/tex], the slope must be equals to [tex]0[/tex].

So, [tex]y=0[/tex] is the only option in which the slope is equals to zero and so, it is parallel to the line [tex]y=4[/tex].

Answers

Answer:

It should be $32 - $22.50.

Step-by-step explanation:

This is because we're trying to find out the amount she received. So we will subtract the amount she already has from how much she now has to figure out how much she received. 32 - 22.50 = 9.50.

A rubber ball bounces after it is dropped from a height of 212 feet, and it
continues to bounce one-half the height from which it last fell. How many
bounces does it take
before the ball falls less than one foot?

Answers

Answer:

C. 8 bounces

Step-by-step explanation:

To solve this, you can write an equation before turning it into an inequality:

y = 212*(1/2^x)

(x is bounces, y is height)

Now you can change it into an inequality to fit the height of less than 1:

1 > 212*(1/2^x)

In order for the right side of the equation to be less than 1, 2^x must be greater than 212 (because 212*(1/212) is 1, so if the denominator is greater, it'll be less than 1). 2^8 is 256, which is greater than 212, so that means x is 8.

Because x represents bounces, that means the ball's height will be under 1 foot after 8 bounces.
