Help please solve by factoring

Help Please Solve By Factoring

Answers

Answer 1

We know that 6x(-7) is -42 and we also know that 6+(-7) is -1.

So we can write

[tex]x^2+6x-7x-42[/tex]

[tex]x(x+6)-7(x+6)[/tex]

[tex](x-7)(x+6)[/tex]

So our solutions are [tex]x=7,-6[/tex]

Answers

Answer

I think first 3

Step-by-step explanation:

A slope is also known as the gradient of a line. The points that would be on lines that represent a unit rate greater than the one represented in the table are the first three points.

What is Slope?

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The slope of the function that the table represents is 2.2.

Also, the slope of the different points and the origin will be shown on the points that would be on lines that represent a unit rate greater than the one represented in the table are the first three points.

Hence, the points that would be on lines that represent a unit rate greater than the one represented in the table are the first three points.

What are the solutions of the equation x4 – 5x2 – 36 = 0? Use factoring to solve. x = ±2 and x = ±3 x = ±2i and x = ±3 x = ±2 and x = ±3i x = ±2i and x = ±3i

Answers

Answer:

[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]

Step-by-step explanation:

So we have the equation:

[tex]x^4-5x^2-36=0[/tex]

Let's let u equal x² so:

[tex]u^2-5u-36=0[/tex]

Factor. We can use -9 and 4. So:

[tex]u^2+4u-9u-36=0[/tex]

From the first two terms, factor out a u.

From the last two terms, factor out a -9. So:

[tex]u(u+4)-9(u+4)=0[/tex]

Grouping:

[tex](u-9)(u+4)=0[/tex]

Zero Product Property:

[tex]u-9=0 \text{ or } u+4=0[/tex]

On the left, add 9. On the right, subtract 4:

[tex]u=9\text{ or } u=-4[/tex]

Substitute back u:

[tex]x^2=9\text{ or } x^2=-4[/tex]

Take the square root:

[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]

Answers

Solution :

7658 - 7000 = 658 - blank

658 = 658

So here, blank is 0.

547 - 7000 = 658 - blank

-7111 = 658 - blank

Blank = 7769

14 - 7000 = 658 - blank

Blank = 7644

-9x + 12x + 10 simplifies to

Answers

Answer:

[tex] \boxed{\sf 3x + 10} [/tex]

Step-by-step explanation:

Simplify the following:

⇒-9 x + 12 x + 10

Grouping like terms:

⇒(12 x - 9 x) + 10

12 x - 9 x = 3 x:

⇒3 x + 10

3x+10 because you have to combine -9x and 12x which will give you 3x. Then the 10 can’t go to 3x because they aren’t like terms. So your answer is 3x+10.

Which rules define the function graphed below?
y = x; y = 5
y = x + 2; y = 5
y = x; x = 5
y = x + 2; x = 5

Answers

Answer:

B) y=x+2; y=5

Step-by-step explanation:

The rules that define the graphed function are y = x + 2; y = 5

How to determine the rule of the function?

The function is a piecewise function

There are two lines on the graph.

The first line has the following points

(0,2) and (3,5)

Express 2 and 5 as a sum of 2

(0,0 + 2) and (3, 3 + 2)

This means that the y value is the sum of 2 and the x value.

So, we have:

y = x + 2

The other line has a constant value of 5 for all x values

So, we have:

y = 5

Hence, the rules that define the graphed function are y = x + 2; y = 5
