Find an expression which represents the difference when (2x − 6) is subtracted

Mathematics
1 answer:
Sloan [31]1 year ago
4 0

Answer:

-2x + 8

Step-by-step explanation:

(2x - 6) is subtracted from (7 - 5).

First term that into an equation.

Because our first term is being subtracted from our second one, our equation is written as:

(7 - 5) - (2x - 6).

Simplify the first term by subtracting:

7 - 5 = 2

Now simplify the second term by multiplying 2x - 6 by -1 to get them out of the parenthesis. We do this because there is a negative sign in front of it.

-1 (2x - 6)

-2x + 6

Now our equation is:

2 - 2x + 6

Combine like terms:

2 + 6 = 8

So -2x + 8

(2x - 6) subtracted from (7 - 5) is -2x+8

Write an equation in point slope form for the line that passes through the given point and is perpendicular to the graph of the
USPshnik [31]

Answer:

y=-3x-8

Step-by-step explanation:

y=1/3x+9

slope is 1/3

perpendicular slope = m

(m)(1/3) = -1

m = -3

Point slope form

(y+2)/(x+2)=-3

y+2=-3x-6

y=-3x-8

If G is a 3 x 4 matrix and His a 4x 3 matrix, what is the dimension of GH?
Neko [114]

Answer:

3x3

Step-by-step explanation:

G is a 3 x 4 matrix and His a 4x 3 matrix

In multiplication of matrix a particular formula is used

If G = MN and H = NM then GH = MM

So G= 3x4 and H = 4x3

Then GH = 3x3

The above rule is a rule that binds matrix multiplication and allows for an easier calculations and also helps check the possibility of the multiplication.

As for the above, the multiplication is possible an the result of the multiplication will give us a 3x3 matrix

BRAINLIEST ANSWER!! ASAP<br><br> 3(x+1)+6=-9<br> PLEASE EXPLAIN HOW YOU GOT THE ANSWER
Kryger [21]

Answer:

x=-6

Step-by-step explanation:

use distributive property on the () and times x and 1 by three

then you subtract 6 from both sides

then subtract three from both sides

then divide both sides by 3

your work would look like this:

3(x+1)+6=-9

3x+3+6=-9

3x+3=-15

3x=-18

x=-6

Hope this helps!

Draw a number line to<br><br> represent the inequality.<br><br> y s 23
Mkey [24]

Answer:

The number lines are shown below.

Step-by-step explanation:

In the given problem the sign of inequality is missing.

We know, that there are 4 signs of inequality ">", "<", "≥" and "≤".

The possible inequalityes are

y>23

y

y\geq 23

y\leq 23

In y>23, all points on the right side of 23 are included in the solution set.

In y, all points on the left side of 23 are included in the solution set.

In y\geq 23, 23 and all points on the right side of 23 are included in the solution set.

In y\leq 23, 23 all points on the left side of 23 are included in the solution set.
