Answer:
-36x^2+1
Step-by-step explanation:
(1+6x)(1-6x)
= 1^2(6x)^2
= -36x^2+1
Answer:
vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)
Step-by-step explanation:
The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.
So you can plot (6,0) and (2,0).
The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4
We just have to find the y-coordinate for when x=4.
Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.
So the vertex is at (4,-4).
Answer+Step-by-step explanation:
m = man's age
s = son's age
m=s+36
(m+8)=3*(s+8)
Resolves to: s=10, m=46
So the man is 46 (=10+36).
In 8 years, son is 18 (=10+8), man is 54 (=3*18 and 46+8), thank you.
Answer:
By multiplying each ratio by the second number of the other ratio, you can determine if they are equivalent. Multiply both numbers in the first ratio by the second number of the second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by 15 and 5 by 15 to get 45:75.
