Which of these expressions equal 15 when x=1/2 and y=3? Circle all that apply. Please help with this my teacher need me to work out xy+3 1/2+20x Btw guys 3 1/2 are mixed numbers if your wondering

Answers

Answer 1

Answer:

15

Step-by-step explanation:

First you would replace the x and y's with 1/2 and 3.

So it would look like: (1/2) (3) + 3 1/2 + 20 (1/2)

Next, you go by PEMDAS (parenthesis, exponents, multiplications, division, addition, subtraction)

So you would first multiply and the parenthesis that I added mean multiplication.

1.5 + 3.5 + 10

So then all that is left to do is add because I multiplied everything out.

So it is 5 + 10 which is 15

What is an equation of the line that passes through the points (7, 4) and (-5, 4)

Answers

Answer:

Equation of the line that passes through the points (7, 4) and (-5, 4) is

[tex]y=4[/tex]

Step-by-step explanation:

Equation of line in two point form is given as

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]  ----------(1)

Here

[tex](x_1, y_1) = (7, 4) \ \ \ and \ \ \ (x_2, y_2)=(-5, 4)[/tex]

Substituting values in equation (1)

[tex]y-4 =\frac{4-4}{-5-7} (x-7)[/tex]

[tex]y-4 =0[/tex]

[tex]y=4[/tex]

Hi there! :)

[tex]\large\boxed{\text{ x = 9}}[/tex]

The two angles pictured are vertical angles, therefore:

8x - 6 = 6x + 12

Solve for x by subtracting 6x from both sides:

2x - 6 = 12

Add 6 to both sides:

2x = 18

Divide both sides by 2:

x = 9.

Answer:

9 is ur answer

Step-by-step explanation:

8x-6=6x+12

8x-6x=12+6

2x=18

x=9
