Answer:
x^2 - 3x - 30
Step-by-step explanation:
step 1: -9 + -1 = -10
-3 + -3 = -6
-1 + -9 = -10
1 + 9 = 10
3 + 3 = 6
9 + 1 = 10
No two factors can be found
Trinomial can not be factored
step 2: ((3x2 + 5x) - 12) - 2 • (x2 + 4x + 9)
step 3: -30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
so the answer is x^2-3x-30
C. y=-2x+1
You can test this by inputting each value of X into that equation, noticing that the Y value is always correct when you use that equation.
10 more than 23 is 33 because 10 +23 = 33.
Answer:
<u><em>As the penny falls 320 meters, its vertical velocity increases at the rate of 9.8 m/s each second. Use the following equation to determine its speed when it hits the ground. </em></u>
<u><em>
</em></u>
<u><em>vf^2 = vi^2 + 2 * a * d, vi = 0 </em></u>
<u><em>vf^2 = 2 * 9.8 * 320 </em></u>
<u><em>vf = √6272 </em></u>
<u><em>
</em></u>
<u><em>This is approximately 79 m/s. I hope this helps you to understand how to solve this type of problem.</em></u>
