You should do the FOIL method! let’s walk through it!

(w+2)(w-3)

step 1. F means to multiply the front letter or number whichever it might be inside the parentheses, in this cause it’s w. so it would be (w)(w)= w^2

step 2. O means to multiply the outer letter or number whichever it might be inside the parentheses, in this cause it’s w and -3. so it would be (w)(-3)= -3w

step 3. I means to multiply the inner letter or number whichever it might be inside the parentheses, in this cause it’s w and 2. so it would be (w)(2)= 2w

step 4. L means to multiply the last letter or number whichever it might be inside the parentheses, in this cause it’s 2 and -3. so it would be (2)(-3)= -6
*REMEMBER a positive (+) * a negative (-) is a negative (-)

now you have the equation: W^2 -3w + 2w -6 = w^2 -w -6

A first number plus twice a second number is 11. Twice the first number plus the second totals 16. Find the numbers.
satela [25.4K]
<h3><u>The first number, x, is equal to 7.</u></h3><h3><u>The second number, y, is equal to 2.</u></h3>

x + 2y = 11

2x + y = 16

We can subtract 2y from both sides of the first equation to get a value for x.

x = 11 - 2y

Because we have a value for x, we can plug it into the second equation.

2(11 - 2y) + y = 16

Distributive property.

22 - 4y + y = 16

Combine like terms.

22 - 3y = 16

Subtract 22 from both sides.

-3y = -6

Divide both sides by -3.

y = 2

Now that we have a value for y, we can plug it into either equation to solve for x.

x + 2(2) = 11

x + 4 = 11

Subtract 4 from both sides.

x = 7

Answer:

14

Step-by-step explanation:

To get the answer, add the whole numbers together and then add the fractions together:

9 + 4 = 13

(You can even stop here because 14 is the closest to 13)

Now, add the fractions:

\frac{2}{3}+\frac{1}{5}

To add fractions you have to have a common denominator. To find the common denominator multiply 3 by 5, and 5 by 3. Like this:

(\frac{5}{5})\frac{2}{3}  + \frac{1}{5} (\frac{3}{3} )

Simplify:

\frac{10}{15} +\frac{3}{15}              Distribute everything from above

\frac{13}{15}                      Add

So, the whole fraction will look like this 13\frac{13}{15}. This is closest to 14.

Hope this helps!! Ask questions if you need!

Find the slope of the line between the ordered pair (−1,4)and(4,−1) what is the answer??? please answer correctly
luda_lava [24]

9514 1404 393

Answer:

  -1

Step-by-step explanation:

The slope formula works nicely for this.

  m = (y2 -y1)/(x2 -x1)

  m = (-1 -4)/(4 -(-1)) = -5/5 = -1

The slope of the line between the given points is -1.
