Greeting!
15x² = x + 2
15x² - x -2= 0
Factor left side
(5x-2)(3x+1)=0
Set factors equal to 0
5x - 2 = 0 or 3x + 1 -0
x = 2/5 or x= -1/3
I hope that helps!

Answer:
There are the only triangles with right angles
Step-by-step explanation:
Answer:
The slope is -3.
Step-by-step explanation:
The slope is equal to the change in y over the change in x.
First, we take the two y values, -2 and -8, and subtract the SECOND from the FIRST: -2 - (-8) = -2 + 8 = 6 (= change in y)
Second, we take the two x values, 5 and 7, and subtract the SECOND from the FIRST: 5 - 7 = -2 (= change in x)
Finally, we make a fraction, the change in y over the change in x:
6/-2 = -3
The slope is -3.

someone needs to answer this like rly
Hey there! Hope I can help!
<span><span>P is the principal amount, $550.00.
</span><span>R is the interest rate, 3% per year, or in decimal form, 3/100 = 0.03.
</span><span>T is the time involved, 10 year(s) time period.
</span><span>So, t is the 10 year time period.
</span></span><span>To find the simple interest, we multiply 550 × 0.03 × 10 to get $165.00
</span>
<span>Then the interest is added onto the principal to figure the new amount after 10 years. </span>
<span>550.00 + 165.00 = 715.00 > $715.00 after 10 years.</span><span>
Hope this helps!
