WILL MARK BRAINLIEST in detail, what would you do in order to graph y = 3x -5

Hunter-Best [27]

So first, you need to identify the parts of this equation.

3x is the slope of the line, which is $\frac{3}{1}$ .

-5 is the y-intercept. or the part of the line that touches the y-axis.

The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.

Now, use the slope $\frac{3}{1}$ to find your next plot. Since slope is $\frac{rise}{run}$ , you go up three, and over to the right one.

Now, draw a line connecting the dots. Your slope should be positive and look like > /

What are the coordinates of the points (2,-3) after a counter clockwise rotation of 90 about the Origin?

Ber [7]

Step-by-step explanation:

(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.

Any point in the 1st quadrant has both positive x and y coordinates.

So the answer is (3, 2).

I need help with geometry. Find x.

I am Lyosha [343]

Answer:

Part 9) $x=5$

Part 10) $x=-9$

Step-by-step explanation:

we know that

The Midpoint Theorem states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

Part 9) we know that

Point Q is the midpoint segment XY (QY=QX)

Point R is the midpoint segment XW (RW=RX)

Applying the Midpoint Theorem

RQ is parallel to WY

and

$RQ=\frac{1}{2}WY$

we have

$RQ=2x-3\\WY=x+9$

substitute

$2x-3=\frac{1}{2}(x+9)$

solve for x

$4x-6=(x+9)$

$4x-x=9+6$

$3x=15$

$x=5$

Part 10) we know that

Point B is the midpoint segment TS (BS=BT)

Point C is the midpoint segment RS (CS=CR)

Applying the Midpoint Theorem

BC is parallel to TR

and

$BC=\frac{1}{2}TR$

we have

$BC=x+19\\TR=x+29$

substitute

$x+19=\frac{1}{2}(x+29)$

solve for x

$2x+38=(x+29)$

$2x-x=29-38$

$x=-9$

Nancy is single, with an Adjusted Gross Income of $25,985. She has one exemption of $8200. What is the amount of tax due? $2301

Fudgin [204]

Take her gross income and subtract her exemption of 8200. The number you get is what she needs to pay tax on. I can't really go any further, I need a table of information to go off of to further the answer. Although assuming you would have a tax bracket, you would simply just read to the right and a value in the single column will be your answer. Sorry, not much to go off here :/.
