Answer: m=1

Step-by-step explanation:

-19-6m= -m-40+16m

Add 40 to both sides then add 6m to both sides you’ll get: 21=21m

Divide my 21 and you’ll get your answer which is 1 :)

Answer:

m=1

Step-by-step explanation:

1st, distribute the -8 on the right side in the paranthesis.

-19-6m=-m-40+16m

Since the 8 is a negative, -2m x -8 = positive 16m

2nd, group the m's on 1 side, and numbers on the other.

-19+40= -m+16m+6m

40 becomes positive and 6m become negative as they switch sides.

3rd, simplify both sides.

21=21m

Finally, divide both sides by 21.

1=m

Good Luck!

Steps:

1. -19-6m=-m-8(5-2m) (Next, multiply 5 and -2m by -8.)

2. -19-6m=-m-40+16m (Next, group the #'s and m's together.)

3. -19+40=-m+16m+6m (Next, simplify both sides.)

4. 21=21m (Next, divide both sides by 21.)

5. 1=m

Your answer is m=1.

Find the remainder for the quotient using either substitution or synthetic division.

zaharov [31]

(x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15 as there is no remaider.

<h3>What is a factor of a polynomial?</h3>

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given a polynomial function f(x) = x³ - x² - 17x -15.

If (x - 5) is it's factor then f(5) = 0.

∴ f(x) = x³ - x² - 17x -15.

f(5) = 5³ - 5² - 17(5) - 15.

f(5) = 125 - 25 - 85 - 15.

f(5) = 0.

So, the remainder is zero hence (x - 5) is a factor of the polynomial function f(x) = x³ - x² - 17x -15.

Find the equation of the line that is perpendicular to y = 1/4x – 2 and passes though the point (5, –2). A) y = –1/4x + 18 B) y

Mashcka [7]

Since our line is perpendicular to this line, the slope of

our line is the negative reciprocal of 1/4, which is -4/1.

Remember, negative reciprocal is just a fancy way

of saying flip the fraction and change the sign.

So the slope of our line is -4/1 and we use this slope along

with our given point to write the equation of our line.

Start with the point-slope formula.

Y - y1 = m(x - x1).

~Substitute

Y - -2 = -4/1(x - 5).

Minus a negative is plus a positive.

Y + 2 = -4/1x + 20.

Subtract 2 from both sides.

Y = -4/1x + 18

So, our answer is C.

PLEASE HELP! (1/4) - 50 POINTS -

Annette [7]

Answer:

D) 0.35

Step-by-step explanation:

The table gives the area between z=0 and the given magnitude of z. That is, the area between z = 0 and z = -0.6 is 0.23, as found in the 0.6 column of the table. Similarly, the area between z = 0 and z = 0.3 is 0.12, as found in the 0.3 column of the table.

The area between z = -0.6 and z = +0.3 is the sum of these areas:

p(-.6<z<.3) = 0.23 +0.12 = 0.35

Mr. Pham wrote the equation below on the board.

Margaret [11]

Answer:

x=5.5

Step-by-step explanation:

We can solve this equation by using the various properties and PEMDAS.

First, we would want to subtract 18 on both sides, to even out the equation.

The result is -7x=-38.5

Now we can isolate the x by dividing both sides by -7.

-38/-7=5.5

Thus, x=5.5

Hope this helps!

What are the values of the variables

White raven [17]

Answer:

Step-by-step explanation:

we know that according to the isosceles triangle theorem, that the angles of the triangle are 90, 2x+3, 2x+3

from the triangle angle sum theorem, we know that 4x+6 = 90

solving, we get 4x=84, x=21
