HELPPPP PLSSS You start at (3, -5). You move left 4 units and right 4 units. Where do you end? 4 3 IC 1 Х F -5 -4 -3 -2 -1 0 1 3 5 N -2 ܚ ܛ -5​

Answers

Answer:

here you go :)

Step-by-step explanation:

You can approach this problem by thinking about going in the opposite of the directions indicated starting at the point (3, 4).

If you ended at an x-coordinate of 3 after having moved 4 to the left, then you can start at 3 and move 4 to the right to see what x -coordinate you started at:  3 + 4 = 7

The x coordinate of the STARTING point would have been 7.

You can do the same with the y-coordinate: start at 4 and travel down 1 unit.  The y-coordinate of the STARTING point would be 3.

Therefore, the coordinates of the starting point would have been  (7,3)

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(- 2x² + 2x + 2) - 4x(- 2x² + 2x + 2) - 5(- 2x² + 2x + 2) ← distribute parenthesis

The slope is the “change in y over the change in x,” also referred to as “rise over run.”

Pick any two points and calculate the difference in their y-values and divide that by the difference in their x-values.

Notice that all y-values are the same, so your “change in y” or your “rise” is always 0.

0/anything = 0 (as long as the denominator isn’t 0)

So, your slope here is 0.

[tex]\frac{1}{3} (21y + 39) = -36[/tex]

Answers

1/3(21y+39)=-26 can be simplified into

7y +13 = -26

Next, subtract 13 from both sides

7y= -39

Now divide both sides by 7

Your answer is y=-39/7

Answer:

y = -7

Step-by-step explanation:

1/3 (21y+39) = -36

Distribute

7y +13 = -36

Subtract 13 from each side

7y+13-13 = -36-13

7y = -49

Divide each side by 7

7y/7 = -49/7

y = -7

Find the area of the following quadrilateral.

Answers

Answer: 480

Step-by-step explanation:

The quadrilateral ABCD is a trapezium

The formula for area of trapezium is

Area of trapezium = 1/2 × (parallel side 1 + parallel side 2) × h

So we can place the given values into the formula.

We get

Area = 1/2 × (9+15) × 40

Area = 1/2 × 24 × 40

By multiplying all of them we get

Area = 480cm

Answer: 124 degrees

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

Explanation:

If we assume these two things:

JC parallel to KDJA parallel to HB

Then this would allow us to say that angle EJF = angle FHG because they are corresponding angles.

So that means angle FHG = 56

This then leads to:

angle FHK = 180 - (angle FHG) = 180 - 56 = 124 degrees
