What factors multiply to -80 and add to 6

Mathematics
1 answer:
forsale [732]3 years ago
7 0

80 = -1(80), -2(40), -4(20), -5(4),

Total answers include: -81, 79, -42, 16, -9, and 1.

None of them add up to 6!

Are you doing polynomial equations?

If so, you can solve it the hard way.

x^2 + 6x -80 = 0

(x^2 + 6x + 9) - 80 = 9

(x+3)^2 = 89

(x+3) = 9.43

x = 6.43

If you're not doing those then I'm afraid your question has no answer.

Hope that helps!

Write in slope intercept form an equation of the line that passes through (-2,5),(-1,1)
Juliette [100K]

Answer:

y=-4x-3

Step-by-step explanation:

Hi there!

We are given the following two points: (-2,5) and (-1,1)

We want to write the equation of the line that passes through these two lines in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

First, let's find the slope

The formula for the slope (m) calculated from 2 points is \frac{y_2-y_1}{x_2-x_1}, where (x_1, y_1) and (x_2, y_2) are points

We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion

x_1=-2\\y_1=5\\x_2=-1\\y_2=1

Now substitute into the formula

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{1-5}{-1--2}
Simplify

m=\frac{1-5}{-1+2}

Subtract

m=\frac{-4}{1}

Divide

m=-4

Now substitute -4 as m into the equation:

y=-4x+b

Now we need to find b

As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b.

Taking (-2,5) for example:

Substitute -2 as x and 5 as y:

5=-4(-2)+b

Multiply

5=8+b

Subtract 8 from both sides

-3=b

Substitute -3 as b.

y=-4x-3

Hope this helps!

Solve the equation <br> (If possible please show work)
deff fn [24]

Answer:

x=-3

Step-by-step explanation:

So we have the equation:

-2(-x-4)+3=-7-4x

First, distribute the left side:

-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x

Add values on the left side:

2x+11=-7-4x

Add 7 to both sides. The right side cancels:

(2x+11)+7=(-7-4x)+7\\2x+18=-4x

Subtract 2x from both sides. The left side cancels:

(2x+18)-2x=(-4x)-2x\\18=-6x

Divide both sides by -6:

(-6x)/-6=18/-6\\x=-3

Therefore, x equals -3.
