Help Please :( I Am Stuck

Answers

Answer 1

Answer: We all hate it when we are stuck! The slope is -1/2.

Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.

Answer 2
It is -2/1 or just -2 because you must do the rise first which is counting downwards or upward then the run counting to the left or right

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)

Answers

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

Answer:

y  = (2/5)*x + 18

Step-by-step explanation:

Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .

Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y  = (2/5)*x + 18.

I need help with geometry

Answers

Answer:

It 12

Step-by-step explanation:

This is because the scale factor between the triangles is 1.75, so I divide 21 by 1.75 and got 12

Hope this helped

We first have to find 2 pairs of sides that proportional.

35/20=42/24=7/4

and 21/b should be 7/4 as well because if we want the triangles to be similar the sides should be in proportion.

21/b=7/4

84=7b

b=12

Done!

f(x)=-2(x+1)^2-12 in the form f(x) =ax^2+bx+c

Answers

Answer:

[tex] \boxed{ f(x) = -2x^2 - 4x - 14 } [/tex]

Step-by-step explanation:

f(x) = -2(x+1)²-12

f(x) = -2(x²+2x+1) - 12

f(x) = -2x² - 4x - 2 - 12

f(x) = -2x² - 4x - 14

In the first quadrant, you start at (5,7) And move 2 units right and 2 units down What point will you end up on

Answers

Answer: (7,5)
Explanation:
5+2= 7
7-2= 5
(X,Y)
Left to right- the X axis, moving up 2 units so you add 2 to your x value which is 5.

Up and Down- the y axis, moving down 2 units so you subtract 2 from the y value, being 7.

20y-10x=5 in slope intercept form can you explain the steps

Answers

Given:

The equation is

[tex]20y-10x+5[/tex]

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

[tex]y=mx+b[/tex]

Where, m is slope and b is the y-intercept.

We have,

[tex]20y-10x=5[/tex]

We need to isolate y. Add 10x on both sides.

[tex]20y-10x+10x=5+10x[/tex]

[tex]20y=5+10x[/tex]

Divide both sides by 20.

[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]

[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]

[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]

[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]

Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].
