Which of the following shows of the slope of the line and one point on the line?
uysha [10]
Answer is choice D

This is the only answer choice with a negative slope, so we don't even need to look at the point really. Though if you wanted, you can confirm that the point (1,-3) is on the diagonal line. This point is shown in red in the attached image.

To find that the slope is -6/5, you pick two points on the diagonal line and use the slope formula. Two points you can use are (1,-3) and (-4,3).
The slope formula is m = (y2-y1)/(x2-x1)

Note: The negative slope is because we move downhill as we move from left to right along the diagonal line.

If the zeros are 1 and -4, what are the factors?
Natali5045456 [20]

Answer:

(x - 1) and (x + 4)

Step-by-step explanation:

Given the zeros of a polynomial, say x = a, x = b then the factors are

(x - a), (x - b) and the polynomial is the product of the factors, that is

f(x) = (x - a)(x - b)

Here the zeros are x = 1 and x = - 4, thus the factors are

(x - 1) and (x - (- 4)), that is (x - 1) and (x + 4)

How can you find the area of a polygon that is not for which you know an area formula
kipiarov [429]

Answer:

See below.

Step-by-step explanation:

If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula.

If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:

Example:

Find the area of the composite figure by splitting the figure into two shapes - two rectangles.

One rectangle is 2 x 9 = 18.

The other rectangle is 2 x 4 = 8.

Together the area is 18 + 8 = 26.

If 3 is added to twice a number, the result is 17. Find the number
Crank

Answer:

7

Step-by-step explanation:

The text of this expression is:

"If 3 is added to twice a number, the result is 17. Find the number"

Let's call x the number we want to find.

Twice the number is equal to

2x

So, if we add 3 to 2x, we get

3+2x

And we know that this is equal to 17:

3+2x=17

Now we can solve the equation to find x: first, we subtract 3 from both sides

3+2x-3=17-3\\2x=14

Now we divide both sides by 2:

\frac{2x}{2}=\frac{14}{2}\\x=7
