3(x + 7)2 + 8 = 440 using square roots

1 answer:

7 0

X= 65
Explanation:
Simplify both sides of equations
3(x)+7)(2)+8=440
6x+42+8=440 (Distribute)
(6x)+(42+8)=440
(Combine Like Terms)

Step 2: subtract 50 from each side
6x+50−50=440-50 6x=390

Step 3: Divide both sides by 6
6x/6 = 390/6

Which equation represents a line which is parallel to the line x-3y=15?

LekaFEV [45]

Step-by-step explanation:

Two lines that are parallel have the same slope. If we make $x - 3y = 15$ in to slope-intercept form it'll be like this:

$x - 3y = 15 \\ -3y = 15 - x \\ y = \frac{15 - x}{-3} \\ y = \frac{1}{3}x - 5$

Now we know $y = \frac{1}{3}x - 5\\$ as its slope-intercept form we can see the slope is $\frac{1} {3}\\$ .

$y = \frac{1}{3}x + 4\\$ has the same slope as $y = \frac{1}{3}x - 5\\$ so they are both parallel.

<h3>Answer:</h3>

$y = \frac{1}{3}x + 4\\$
