Simplify -2(x - 5) + 4(9 + x).

Answer:

Green line

Step-by-step explanation:

This is the only line that has coordinates (1,2) and the slope is positive.

Answer: You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Answer:

$3.00

Step-by-step explanation:

$3.00 x .2 = 0.60. added to original

The original price of the yo-yo in a shop is $3.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

It is given that the price of a yo-yo in a shop increased by 20% and is now $3.60.

The original price will be calculated as let the original price is x dollars. Then from the question, the expression will be formed as below:-

1.20x = 3.60

x = 3.60 / 1.20

Divide 3.60 by 1.20 to get the value of x.

x = $3

It means that the 20 percent is equal to the amount of $0.6.

Therefore, the original price of the yo-yo in a shop is $3.

Answer:

slope = 35/2

y intercept is 0

Step-by-step explanation:

the y-intercept is 0 because you can see from the graph that it intersect with y-axis at (0,0)

Slope = rise /run

pick a point (8, 140)

rise = 140

run = 8

slope = 140/8 = 70/4 = 35/2

Answer:

y = 2x + 16

Step-by-step explanation:

4x - 2y = 4

-2y = -4x + 4

y = -4/-2x + 4/-2

y = 2x - 2

Slope: 2

Point: (3,22)

y-intercept: 22 - (2)(3) = 22 - 6 = 16

Answer:

y=2x+16 or 2x-y=-16

Step-by-step explanation:

Hi there!

We are given the equation 4x-2y=4, and we want to write an equation for the line parallel to it, that also passes through (3, 22)

First, let's find the slope of the line, as parallel lines have the same slope.

In order to find the slope, we can convert the equation from standard form (ax+by=c) into slope-intercept form (y=mx+b).

Start by subtracting 4x from both sides:

-2y=-4x+4

Divide both sides by -2

y=2x-2

2 is in the place where x is, so the slope of the line is 2

It's also the slope of the line parallel to it.

Writing the equation in slope-intercept form, this is the equation so far:

y=2x+b

Now let's find b

Since the equation passes through the point (3,22), we can use it to help solve for b

Substitute 22 as y and 3 as x:

22=2(3)+b

Multiply

22=6+b

Subtract 6 from both sides

16=b

Substitute 16 as b in the equation.

y=2x+16

We can stop right here, but we can also re-convert it into standard form

To do that, subtract 2x from both sides:

-2x+y=16

There's a rule that the coefficient in front of x CANNOT be negative; in order to change the sign, multiply both sides of the equation by -1

2x-y=-16

Hope this helps!
