Find The Equation Of The Linepassing Through The Points (2,11)and (-8,-19).y = [ ? ]x + [ ]

Answers

Answer 1

Given:

A line passes through two points are (2,11) and (-8,-19).

To find:

The equation of the line.

Solution:

The line passes through two points are (2,11) and (-8,-19). So, the equation of line is

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

[tex]y-11=\dfrac{-19-11}{-8-2}(x-2)[/tex]

[tex]y-11=\dfrac{-30}{-10}(x-2)[/tex]

[tex]y-11=3(x-2)[/tex]

Using distributive property, we get

[tex]y-11=3(x)+3(-2)[/tex]

[tex]y-11=3x-6[/tex]

Adding 11 on both sides, we get

[tex]y=3x-6+11[/tex]

[tex]y=3x+5[/tex]

Therefore, the equation of line is [tex]y=3x+5[/tex]. So, the missing values are 3 and 5 respectively.

Answers

Answer:

1

Step-by-step explanation:

Algebraically, both sides of the equation must equal each other.

[tex]4(12x-6)=6(-4+5x)+18[/tex]

Distribute

[tex]4(12x-6)=6(-4+5x)+18\\48x-24=30x-24+18\\[/tex]

Add, subtract, multiply, or divide to isolate x.

[tex]48x-24=30x-24+18\\48x-24=30x-6\\18x=18\\x=1[/tex]

The solution to this equation is 1.

To test, you can plug in x with 1 and you will see that both sides equal each other.

Answer: X=0

Explanation:
- Distribute 4 through the first set of parenthesis. It will be 48x-24=6(-4+5x)+10x
- Now distribute 6 through the second set of parenthesis. Now it will be 48x-24=-24+30x+10x
- Cancel equal terms on both sides of the equation (both of the -24’s) So it will be 48x=30x+10x
- Collect like terms (add 30x and 10x). You will get 48x=40x
- Move the variable to the left-hand side. It will be 48x-40x=0
- Collect like terms (Subtract 40x from 48x). You should get 8x=0
- Divide both sides by 8. X=0

Find the value of x if 9^1/2 • 9^1/2 = x^√81

Answers

Answer:

(√9)^2x-1/2 = 1/81

3^2x-1/2 = 1/(3)⁴. (as √9 = 3)

3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)

as base are equal exponents are equal

so 3 gets cancelled out

2x-1/2 = -4

(4x-1)/2 = -4

4x-1 = -8

x = -7/4

If f(x) = -7x+1 and g(x) = -5x+3, what is (f+g)(x)?

Answers

Answer:

-12x + 4

Step-by-step explanation:

Just write the givens like this f(x) + g(x)  

f(x) + g(x) = -7x + 1  + - 5x + 3

f(x) + g(x) = - 7x + 1 - 5x + 3

f(x) + g(x) = - 12x + 4

Answers

Answer:

-7/4

Step-by-step explanation:

When you find the perpendicular slope, you take the opposite reciprocal of the original slope. For 4/7, the opposite is -4/7, and the reciprocal of that is -7/4.

Answer:

5-( 2.40+1.33 )= $1.27

Step-by-step explanation:

If you add $2.40 to $1.33 you get $3.73, the total amount of money she spent on drinks and snacks. Then you would need to subtract $3.73 from $5.00, which is $1.27.
