Answer:

Step-by-step explanation:

Equation is y= 200x+30000

Table in order goes 30000, 30200, 30400, 30600, 30800

To graph your y intercept would be 30000 and slope is 200

Choose the equation that represents a line that passes through points (−3, 2) and (2, 1).

guapka [62]

Answer:

$y=-\frac{1}{5}x+\frac{7}{5}$

Step-by-step explanation:

The given line passes through points (−3, 2) and (2, 1).

We use the formula $m=\frac{y_2-y_1}{x_2-x_1}$ to find the slope of this line.

$\implies \frac{1-2}{2--3}=\frac{-1}{5}$

We use the point slope formula:

$y-y_1=m(x-x_1)$

$y-2=-\frac{1}{5}(x--3)$

$y-2=-\frac{1}{5}(x+3)$

We expand to get:

$y-2=-\frac{1}{5}x-\frac{3}{5}$

$y=-\frac{1}{5}x-\frac{3}{5}+2$

The slope intercept form of the line is:

$y=-\frac{1}{5}x+\frac{7}{5}$

Variable y varies directly with variable x, and y=16 when x= 12<br><br> y= ___ x

laiz [17]

When y is directly proportional to x,
y=kx (k is a constant)
when x=12, y=16
12k=16
k=4/3
hence, y=4/3x

Find the value of y.

Phoenix [80]

$\boxed{y=6\sqrt{3}}$

<h2>Explanation:</h2>

For a better understanding of the problem I've built up two triangles from the given triangular shape. So these two triangles are similar. Therefore, we can solve this problem by using ratios and corresponding sides in this way:

$\frac{x}{3}=\frac{12}{x} \\ \\ x^2=36 \\ \\ x=\sqrt{36} \\ \\ x=6$

But our goal is to find y. Let's call w the height of the small triangle, then:

$w=\sqrt{6^2-3^2}=3\sqrt{3}$

Applying the concept of ratios again:

$\frac{y}{w}=\frac{x}{3} \\ \\ y=w \left(\frac{x}{3}\right) \\ \\ y=3\sqrt{3}\left(\frac{6}{3}\right) \\ \\ \boxed{y=6\sqrt{3}}$

Determine if the linear system

zubka84 [21]

Answer:

b. The system is not in echelon form because the system is not organized in descending "stair step" pattern so that the index of the leading variables increases from the top to bottom.

Step-by-step explanation:

The given linear system has a equation which is not in echelon form. The echelon is a system which divides the data into rigid hierarchal groups. The given linear equation in not in echelon form as the leading variables are increased from top to bottom indicating descending stair step pattern.
