Using 1st equation:
15 = 16/3 + b
(45-16)/3 = b
29/3 = b

Using last equation:
47 = 16*7/3 + b
(141-112)/3 = b
29/3 = b

For each of the equations below, solve for y in terms of x. !<br> a. 2x – 3y = 12

ira [324]

Answer:

$\large\boxed{y=\dfrac{2}{3}x-4}$

Step-by-step explanation:

$2x-3y=12\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\2x-2x-3y=12-2x\\\\-3y=12-2x\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3y}{-3}=\dfrac{12}{-3}+\dfrac{-2x}{-3}\\\\y=-4+\dfrac{2}{3}x$

Why should you not choose a point on the line to find the direction of shading in an inequality?

PIT_PIT [208]

Answer:

Because we know for a fact that the line has a correct answer. Plus, if you choose a point on the line then it will not give you the visual side of which is correct and which is wrong.

Follow the process of completing the square to solve x2 = -4x + 3.

Vilka [71]

Answer:

(2x+4)^2 = 28

Step-by-step explanation:

$x^2 = -4x + 3$

to apply completing the square method we need x terms on one side

add 4x on both sides

$x^2+4x = 3$

Now we take the coefficient of x term and divide by 2

4 divide by 2 is 2

Now we square it (2)^2 = 4

In completing the square method, we add that number on both sides

$x^2+4x+4 = 3+ 4$

Now we factor x^2 + 4x + 4

(x+2)(x+2) = 7

(x+2)^2 = 7

(x+2)(x+2) = 7

Multiply both sides by 4

2(x+2) * 2(x+2) = 7* 4

(2x+4)(2x+4) = 28

(2x+4)^2 = 28

On a coordinate plane, a line is drawn from point a to point b. point a is at (negative 8, negative 13) and point b is at (4, 11

vladimir2022 [97]

The coordinate for point P which is one-third the length of the line segment from a to b is (-4, -5)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Point a is at (-8, -13) and point b is at (4, 11). Hence the coordinates for point p(x, y) which is one-third the length of the line segment from a to b is:

$x=\frac{1}{3}(4-(-8))+(-8)=-4\\ \\y=\frac{1}{3}(11-(-13))+(-13)=-5$

The coordinate for point P which is one-third the length of the line segment from a to b is (-4, -5)
