Answer:

y=2x+7

Step-by-step explanation:

When an equation is parallel to another, it shares the same slope.

Our original line is y=2x-8, and it is in slope-intercept form (y=mx+b)

This means that our slope is 2 because m represents the slope.

The slope of our parallel line will then also be 2.

<u>We can begin to plug that into point-slope form which is:</u>

y - y1 = m(x - x1)

This is where (x1, y1) is a point the line intersects, and m is the slope.

<u>Plugging in the slope, we'll have:</u>

y - y1 = 2(x - x1)

We also know it intersects the point (-4, -1)

We can plug this into our equation as well.

y - (-1) = m(x - (-4))

y+1=2(x+4)

<u>Now, we can simplify it into slope-intercept form:</u>

y+1=2(x+4)

Distribute

y+1=2x+8

Subtract 1 from both sides

y=2x+8-1

y=2x+7

Answer:

y = 2x + 7

Step-by-step explanation:

y - y1 = m(x - x1)

First, put y and x into the equation and enter the slope, which is 2.

y + 1 = 2(x + 4)

(The negative 1 and 4 are changed to a positive 1 and 4 since the two negative signs cancel each other out)

Next, distribute.

y + 1 = 2x + 8

Then, you move the 1 to the other side of the equation to isolate the y. This will change the 1's sign into a negative and you will result with this after adding like terms:

y = 2x + 7

The equation of the line parallel to y = 2x - 8, and that goes through the point (-4, -1) is y = 2x + 7

If 3 people go to lunch and the bill was $30 and they all give $10 and the waitress comes back with the waitress comes back and
Kryger [21]

Answer

No missing money

Step-by-step explanation:

Original money given to the waiter = $30

Each person paid $10

The waitress comes back with the waitress comes back and said the bill is $25

They gave her $2 for the tip

if each got $1.00 back

Balance = $1.00 × 3

= $3.00

That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)

Each of them got $1.00 back

Total money spent = (cost of meal + tip) + balance of $3.00 given to them

= $27 + $3

= $30

Therefore, there is no missing $1.00

A triangle has the following side lengths: x - 2, x, and 3x + 1. Another triangle has the following side lengths: 2x - 5, x + 4,
notka56 [123]

we know that

Perimeter of a triangle is equal to

P=a+b+c

where

a,b and c are the length sides of the triangle

<u>Find the perimeter of the triangles</u>

<u>Triangle N 1</u>

P=(x-2)+(x)+(3x+1)-------> P=5x-1

<u>Triangle N 2</u>

P=(2x-5)+(x+4)+(6x-7)------> P=9x-8

equate the perimeters

5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7

x=7/4------> x=1.75

therefore

the answer is

x=1.75
