Answer:

x- 5

y- 6

Step-by-step explanation:

A proportional relationship is a relationship for which a proportional constant y/x exists and for which it passes through (0,0) or the origin.

The proportional constant is 6.

18/3=6

42/7=7

54/9=6

Thus the filled in blanks should be x 1, 3, 5, 7, 9 and y 6, 18, 30, 42, 54.

Answer:

<h2>The missing numbers are 5 and 6.</h2>

Step-by-step explanation:

From the given table, if we divide each pair as y/x, we find the ratio is 6.

$\frac{18}{3}=6\\\frac{42}{7}=6\\\frac{54}{9}=6$

Therefore, the missing numbers have to be in the same ratio.

$\frac{x}{1}=6\\x=6$

$\frac{30}{x}=6\\ x=5$

So, the missing numbers are 5 and 6, because they are also in the same ratio of 6.

Answers please! I’m finding the volume and i don’t really get it

MrRa [10]

Answer:

V = 13/2

Step-by-step explanation:

When finding volume you must know the formula on doing so.

<em>Volume = length × width × height</em>

length = $2\frac{1}{2}$ --> $\frac{5}{2}$

width = $2\frac{1}{2}$ --> $\frac{5}{2}$

height = $3\frac{1}{4}$ --> $\frac{13}{4}$

<u>mixed number --> fraction</u>

$V = \frac{5}{2} x \frac{5}{2} x \frac{13}{4}$

$V = \frac{25}{4} x \frac{13}{4}$

$V = \frac{325}{8}$ or $\frac{13}{2}$

Find the equation of the line parallel to 7y+2x-10=0 that passes through the point (2,2)

KiRa [710]

Parallel lines have the same slope.

We have the general form of line. Transform to the slope-intercept form:

$y=mx+b$

m - slope, b - y-intercept

$7y+2x-10=0$ <em>subtract 2x from both sides</em>

$7y-10=-2x$ <em>add 10 to both sides</em>

$7y=-2x+10$ <em>divide both sides by 7</em>

$y=-\dfrac{2}{7}x+\dfrac{10}{7}\to m=-\dfrac{2}{7}$

Therefore we have: $y=-\dfrac{2}{7}x+b$ .

The line passes through the point (2, 2). Substitute the coordinates of the point to the equation of a line:

$2=-\dfrac{2}{7}(2)+b$

$2=-\dfrac{4}{7}+b$ <em>add $\dfrac{4}{7}$ to both sides</em>

$2\dfrac{4}{7}=b$

$y=-\dfrac{2}{7}x+2\dfrac{4}{7}$

$y=-\dfrac{2}{7}x+\dfrac{18}{7}$ <em>multiply both sides by 7</em>

$7y=-2x+18$ <em>subtract 7y from both sides</em>

$0=-2x-7y+18$ <em>change the signs</em>

$2x+7y-18=0$

<h3>Answer:</h3>

$y=-\dfrac{2}{7}x+\dfrac{18}{7}$ slope-intercept form

$2x+7y-18=0$ general form
