What is the equation of the line that passes through the points (2, -4) and (0, 8)?

Answer:

C

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (0, 8)

m = \frac{8+4}{0-2} = \frac{12}{-2} = - 6

note the line passes through the point (0, 8) ⇒ c = 8

y = - 6x + 8 → C

Triangle ABC and triangle DEF are similar. AC = 10, BC = 6, AB = Y in triangle ABC. In triangle DEF DF = X, EF = 5, DE = 7. What
sesenic [268]

Answer:

X=9 and Y=8

Step-by-step explanation:

In relation BC is only 1 unit more than EF. So following that take AC=10, then subtract 1. Get X=9. Then take DE=7 and add 1. Get Y=8

Tell whether the ordered pair is a solution of the system of linear equations.
Lana71 [14]

To figure out if the ordered pairs are a solution to the equations, you would need to plug in the points. Your points are ordered as (x,y)

You would plug in the number that's in the x spot in x, and the number in the y spot in y.

Let's start of with the first problem:

First thing you would do is plug in (-1) to x, and 6 to y.

Your equations would look like this:

6(-1) + 3(6) = 18

2(-1) + 6 = 7

What you would now do is solve the equations. When you solve them, you would get these answers

12 = 18

4 = 7

For #1, it would be no solution because the numbers do not equal each other. (Fun fact) If one of them ends up as a solution, but the other is no solution, the answer would be no solutions because BOTH of them have to be a solution to the equations given in order to be a solution.

If you do the same strategy, (plugging in the numbers to x and y), you would get the rest of the answers for the problems.

I hope this helps, if you need any more assistance, I would be glad to help!

Evaluate the expression when c=6 and d=5.<br> d+ 8c
Elza [17]

Answer:

53

Step-by-step explanation:

when c=6 and d=5 we want to substitute the variables with the numbers in the equation so we'll have

(5) + 8(6)

after evaluating we come up with the answer 53

Geometry// question #8
MAVERICK [17]

Answer:

see explanation

Step-by-step explanation:

The translation rule

(x, y ) → (x + 3, y - 2 )

Means add 3 to the original x- coordinate and subtract 2 from the original y- coordinate, thus

A(- 4, 1 ) → A'(- 4 + 3, 1 - 2 ) → A'(- 1, - 1 )

B(1, 1 ) → B'(1 + 3, 1 - 2 ) → B'(4, - 1 )

C(1, - 2 ) → C'(1 + 3, - 2 - 2 ) → C'(4, - 4 )

D(- 4, - 2 ) → D'(- 4 + 3, - 2 - 2 ) → D'(- 1, - 4 )
