Answer:

Final answer is x^2-x-12.

Step-by-step explanation:

Given expression is \left(x-4\right)\left(x+3\right).

Now we need to find the product of the given expression \left(x-4\right)\left(x+3\right).

\left(x-4\right)\left(x+3\right)

=x\left(x-4\right)+3\left(x-4\right)

=x^2-4x+3x-12

combine like terms

=x^2-1x-12

=x^2-x-12

Hence final answer is x^2-x-12.

ANSWER

(x-4)(x+3) =  {x}^{2}   - x - 12

EXPLANATION

The given product is (x-4)(x+3)

We expand using the distributive property to obtain:

(x-4)(x+3) = x(x + 3) - 4(x + 3)

Expand the parenthesis to obtain:

(x-4)(x+3) =  {x}^{2}  + 3x- 4x  - 12

Combine the similar terms to get:

(x-4)(x+3) =  {x}^{2}   - x - 12

Two collinear points on a line are given in the table below:
katrin [286]

Answer:

(4,3) and (7,2) do not lie on the line

Step-by-step explanation:

Given

(0,0)\ and\ (2,1)

Required

Determine which points that are not on the line

First, we need to determine the slope (m) of the line:

m = \frac{y_2 - y_1}{x_2- x_1}

Where

(x_1,y_1) = (0,0)

(x_2,y_2) = (2,1)

So;

m = \frac{y_2 - y_1}{x_2- x_1}

m = \frac{1 - 0}{2-0}

m = \frac{1}{2}

Next, we determine the line equation using:

y - y_1 = m(x -x_1)

Where

m = \frac{1}{2}

(x_1,y_1) = (0,0)

y - y_1 = m(x -x_1) becomes

y - 0 = \frac{1}{2}(x - 0)

y = \frac{1}{2}x

To determine which point is on the line, we simply plug in the  values of x to in the equation check.

For (4,2)

x = 4 and y =2

Substitute 4 for x and 2 for y in y = \frac{1}{2}x

2 = \frac{1}{2} * 4

2 = \frac{4}{2}

2=2

<em>This point is on the graph</em>

<em></em>

For (4,3)

x = 4 and y = 3

Substitute 4 for x and 3 for y in y = \frac{1}{2}x

3 = \frac{1}{2} * 4

3 = \frac{4}{2}

3 \neq 2

<em>This point is not on the graph</em>

<em></em>

For (7,2)

x = 7 and y = 2

Substitute 7 for x and 2 for y in y = \frac{1}{2}x

2 = \frac{1}{2} * 7

2 = \frac{7}{2}

2 \neq 3.5

<em></em>

<em>This point is not on the graph</em>

<em></em>

<em></em>(\frac{4}{8},\frac{2}{8})<em></em>

<em></em>x = \frac{4}{8} and<em> </em>y = \frac{2}{8}<em></em>

<em>Substitute </em>\frac{4}{8}<em> for x and </em>\frac{2}{8}<em> for y in </em>y = \frac{1}{2}x<em></em>

<em></em>\frac{2}{8} = \frac{1}{2} * \frac{4}{8}<em></em>

<em></em>\frac{2}{8} = \frac{1 * 4}{8 * 2}<em></em>

<em></em>\frac{2}{8} = \frac{4}{16}<em></em>

<em></em>\frac{1}{4} = \frac{1}{4}<em></em>

<em></em>

<em>This point is on the graph</em>

5. Find the value of x.
goldfiish [28.3K]

Answer:

x = 70

Step-by-step explanation:

Interior angles of a 4 sided shape = 360

80+70 = 150

360-150 = 210

210/3 = 70
