Line g is shown on the graph.

alisha [4.7K]

The linear equation that defines the line G can be written as:

y = -(1/3)*x + 5

<h3>How to get the equation of the line G?</h3>

A general linear equation written in the slope-intercept form is:

y = a*x + b

Where a and b are real numbers, a is the slope and b is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

In this case we know that the line passes through (-3, 6) and (0, 5), then the slope is:

a = (5 - 6)/(0 - (-3)) = -1/3

The linear equation is something like:

y = (-1/3)*x + b

We know that it passes through (0, 5), then:

5 = (-1/3)*0 + b

5 = b

We conclude that the linear equation can be written as:

y = -(1/3)*x + 5

14m+m+17m−9m if m=30

NikAS [45]

Answer:

690

Step-by-step explanation:

Put 30 where m is in the expression and do the arithmetic. Or, simpify the expression first, then do the same.

14·30 +30 +17·30 -9·30 = 420 +30 +510 -270 = 690

Simplifying first, you have ...

14m +m +17m -9m = m(14 +1 +17 -9) = 23m

23·30 = 690

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What co

Talja [164]

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle ( $p$ ) is:

$p = 2\cdot b + 2\cdot h$ (1)

Where:

$b$ - Base of the rectangle.

$h$ - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

$b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}$

$b = 5$

If we know that $p = 18$ and $b = 5$ , then the height of the rectangle is:

$2\cdot h = p-2\cdot b$

$h = \frac{p-2\cdot b}{2}$

$h = \frac{p}{2}-b$

$h = 4$

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)
