Answer:

$y=\frac{3}{2}x+8$

Step-by-step explanation:

The equation is in standard form already, which is typically mathematically expressed as, $Ax+By=C$ ; however, They want that equation to be expressed in slope-intercept form. This is commonly known as: $y=mx+b$ .

To get it in this form, we have to isolate y, meaning that we have to get it on one side of the equation, just like the slope-intercept form states.

So, let's do that! We know that -2y is 'By' from the standard form equation is needs to be by itself, so all we have to do is subtract 'Ax'; or in this case, 3x on both sides of the equation to get -2y by itself, leaving us one step closer to finishing the problem!

We now have the following equation: $-2y=-3x-16$

Remember, we have to get not just -2y by itself, we have to get y! We can do that by simply dividing both sides by -2 to get y by itself.

We now have the correct linear equation expressed in the slope-intercept form, which is: $y=\frac{3}{2}x+8$

Answer:this i going to took long time

Step-by-step explanation:Simplifying

3x + -2y = -16

Solving

3x + -2y = -16

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

3x + -2y + 2y = -16 + 2y

Combine like terms: -2y + 2y = 0

3x + 0 = -16 + 2y

3x = -16 + 2y

Divide each side by '3'.

x = -5.333333333 + 0.6666666667y

Simplifying

x = -5.333333333 + 0.6666666667y

If A= (10,4) and B= (2,19) what is the length of AB ?

faust18 [17]

we are given

$A= (10,4) \ and \ B= (2,19)$

we have been asked to find the distance AB.

The distance between the two points can be found using the formula

$D=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2} \\ \\ \text{where two points on the Cartesian plane are } (x_1, x_2) \ and \ (y_1,y_2)\\$

$D=\sqrt{(10-2)^2+(4-19)^2}\\ \\ D=\sqrt{(8)^2+(-15)^2}\\ \\ D=\sqrt{64+225}\\ \\ D=\sqrt{289}\\ \\ D=17$

Length of AB=17

A line segment is sometimes/never/always similar to another line segment, because we can sometimes/never/always map one onto the

svetlana [45]

Answer: "always" for both

A line segment is always similar to another line segment, because we can always map one onto the other using only dilations and rigid transformations.

==================================

Explanation:

A dilation is where we grow or shrink an object. In this case, it would be lengthening or shortening a line. We can dilate any line to get it to any desired length we want. Then to make sure it matches up perfectly with the other line, we can perform translations (aka shifting) and rotations.

In other words, if we have four points A,B,C,D then it is possible to use dilations and rigid transformations to map points A,B to points C,D. The first segment AB would map to segment CD.

For each problem, explain or show your reasoning, a. 160 is what percentage of 40? b. 40 is 160% of what number? c. What number

grigory [225]

Answer:

A. 160 Out of 40 is 400%./// B. The answer is 25/// C. The answer is 3905%

Step-by-step explanation:

( A ) One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 160 is 40% of = 160 X 100 = 400

( B ) The same thing as A but the numbers are switched

One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 40 is 160% of = 40 × 100 = 25

160

( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:

1602 - 40 = 1562

Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:

1562 = 39.05

We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?

39.05 x 100 = 3905%
