The snow is now 22 inches deep. If this was a 70% decrease, what was the initial depth?

Solve the system by substitution. Y = 6x-2 Y = 5x

rusak2 [61]

Answer:

x = 1/3 x=0

Step-by-step explanation:

y=6x-2

2=6x

2/6 = x

1/3=x

y=5x

5x=0

divide both sides by 5

0/5 = 0

2 (x – 4) = -5 How do I do this

DanielleElmas [232]

Step-by-step explanation:

your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda

An identity is the same on both sides of the equals sign

C: 10p + 6 -p=12p-3(p-2)

9p +6 = 12p -3p +6

9p +6 = 9p +6

What are the intercepts of the line -5x-4y=10

Trava [24]

Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.

So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:

$-4y=5x+10$

Next, divide both sides by -4 and your slope-intercept form is $y=-\frac{5}{4}x-\frac{5}{2}$

Looking at this slope-intercept form, the y-intercept is (0, -5/2).

Now to find the x-intercept, just set the y-variable to zero and solve:

$-5x-4*0=10\\-5x=10\\x=-2$

Our x-intercept is (-2,0).

On a coordinates plane, a line passes through ( - 2 , 3 ) and ( 2 , 6 ). Which of the followings lies on the same line.

By direct comparison and definition of line segment we notice that the point (x, y) = (- 6, 0) lies on the line segment AB as each AP is a multiple of former. (Correct choice: C)

<h3>What point lies on a line segment?</h3>

According to linear algebra, a point lies in a line segment if its vector is a multiple of the vector that generates the line segment itself, that is:

AB = k · AP (1)

The vector that generates the line segment is:

AB = (2, 6) - (- 2, 3)

AB = (4, 3)

And the vectors related to each point are:

Case A

AP = (- 2, 12) - (- 2, 3)

AP = (0, 9)

Case B

AP = (6, 12) - (- 2, 3)

AP = (8, 9)

Case C

AP = (- 6, 0) - (- 2, 3)

AP = (- 4, - 3)

Case D

AP = (- 6, 6) - (- 2, 3)

AP = (- 4, 3)

By direct comparison and definition of line segment we notice that the point (x, y) = (- 6, 0) lies on the line segment AB as each AP is a multiple of former. (Correct choice: C)
