Nineteeen less than 6 times a number;

6x - 19

equals; 16 more than the number; this is 16 + x

Thus;

6x - 19 = 16 + x

6x-x = 16 + 19

5x = 35

x = 35/5

x = 7

2. Find the midpoint of PQ.

Answers

Answer:

c) (-2, -1)

Step-by-step explanation:

to find the midpoint of a line, u have to average its coordinates.

Coordinates of P = (2,6)

Coordinates of Q = (-6, -8)

The formula for finding the midpoint is this:

[tex](\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2 } )[/tex]

this basically means u average the points. So for the midpoint's x coordinate, it'll be (2-6)/2 = (-4)/2 = -2

midpoint's y coordinate = (6-8)/2 = (-2)/2 = -1

Therefore, the coordinates of the midpoint are (-2, -1), option c

hope this helps!

Answer:

C

Step-by-step explanation:

Remark

Just eye balling the answer it looks to me like the midpoint is (-2,-1). Of course Eyeballing it is not the way to do math, but it tells you where it is approximately.

Given Points

P: (2,6)

Q: (-6,-8)

Solution

midpoint = (x1 + x2)/2, (y1 + y2)/2

midpoint = (2 + - 6)/2, (6 - 8)/2

midpoint = (-4/2, -2/2)

midpoint = (-2,-1)

4 units x 4 is

16

Answer:

Step-by-step explanation:

First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem

A^2+B^2=C^2.

We know A^2 and B^2, so we need to substitute that into the equation

2^2+4^2=C^2

so now, simplify.

4+16=C^2

20=C^2

Square root of 20 is about 4.5

so 4.5 is the length of the sides of the square.

4.5x4.5=20.25

Urgent help on math plz

Answers

Answer:

x = 14

Step-by-step explanation:

First, organize your work by showing that lines are similar

Line KV is similar to line RV

Line UV is similar to line LV

etc, etc.

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

Now notice that line KV and line RV have the numbers 9 and 18 accordingly

and notice that it's an x2 difference.

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

Now apply the same thing to line UV and LV and divide 26 by 2

That gets us 13

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

Now plug 13 into the equation (2x - 15)

2x - 15 = 13

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

Now solve for X

2x - 15 = 13

Add 15 to each side

2x − 15 + 15 =13 + 15

2x = 28

Divide both sides by 2

2x / 2 = 28 / 2

x = 14

Answers

Answer:

A.

Step-by-step explanation:

Hi there!

By factoring the trinomial, we end with (x-9)(x-4)

However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.

0 = x - 9

0 = x - 4

Using orders of operations, x = 9 and x = 4

Therefore,  A is your answer.
