What is 7= -y+3x? Please explain too

1 answer:

6 0

So, you can't solve for two variables.

Solving for y variable:
7 = -y + 3x
y = 3x + 7

Solving for x variable:
7 = -y + 3x
-3x = -y - 7
x = (-y-7)/-3

What is the answer to (t+8)(-2)=12

Lunna [17]

(t + 8) (-2) = 12

Distributive property >>> -2t + -16 = 12

Inverse operation >>>> -2t + -16+16 = 12+16

Simplify >>>> -2t = 28

Divide >>>> -2t/-2 = 28/-2

Final answer >>>> t = -14

A line passes through the points (2,4) and (5,6) .

Alenkinab [10]

Answer:

Option B and D are correct.

Step-by-step explanation:

Given: A line passes through the points (2,4) and (5,6).

* Case 1:

If a line passes through the points (2, 4) and (5, 6)

Point slope intercept form:

for any two points $(x_1,y_1)$ and $(x_2, y_2)$

then the general form $y -y_1=m(x-x_1)$ for linear equations where m is the slope given by:

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

First calculate slope for the points (2, 4) and (5, 6);

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{6-4}{5-2} = \frac{2}{3}$

then, by point slope intercept form;

$y-4=\frac{2}{3}(x-2)$

* Case 2:

If a line passes through the points (5, 6) and (2, 4)

First calculate slope for the points (5, 6) and (2, 4);

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-6}{2-5} = \frac{-2}{-3}= \frac{2}{3}$

then, by point slope intercept form;

$y-6=\frac{2}{3}(x-5)$

Yes, the only equation of line from the given options which describes the given line are;

$y-4=\frac{2}{3}(x-2)$ and $y-6=\frac{2}{3}(x-5)$
