Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
Answer:
Observation : No two such factors can be found !! Conclusion : Trinomial can not be factored. Equation at the end of step 1 : x2 - 7x - 14 = 0. Step 2 : Parabola, Finding the Vertex: 2.1 Find the Vertex of y = x2-7x-14
Answer:
The third one from left to right
Step-by-step explanation:
Just check that when x = 11
y= ![-\sqrt[3]{11-3}+4=-2+4=2](https://tex.z-dn.net/?f=-%5Csqrt%5B3%5D%7B11-3%7D%2B4%3D-2%2B4%3D2)
So the graph passes through the point (11,2)
