The perimeter is just the sum of all of the side lengths.

p=3x+4+x-10+5x-2

p=9x-8

Add up the lengths of the 3 sides.  Starting with x terms, we get 3x + 4 + x - 10 + 5x - 2.  The x terms combined result in 9x and the constants combined result in -8.  The perimeter is thus 9x - 8 units.

I need help but I need the correct answer everyone is giving me the wrong answer !!
Jlenok [28]

Answer:

y - 2 = 6 (x - 1)

Step-by-step explanation:

Slope intercept form equations look like this:

y - y1 = m (x - x1)

***m = \frac{y2-y1}{x2-x1}

Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:

y - 2 = m (x - 1)

To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.

\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6

Now that we know m = 6, let's plug that back into the original equation to get our final answer:

<u>y - 2 = 6 (x - 1)  </u>          

I hope this helps!

Maya needs $58 to go on a field trip. She has saved $18.50. She earns $6.50 per hour cleaning her neighbor's garden, and she ear
insens350 [35]

She has $18.50 so she needs $39.50.

6.50×3= 19.50

18.50+19.50= 38

5.25×4=21

38+21=59

Maya would have enough money to go on the trip.
