You know 1 is not a root because the sum of the coeffcients of the equation is 14, not zero.
It is fairly easy to try 3 by synthetic division (see attachment), which tells you that 3 is a root and the remaining quadratic factor is x²-3x-5. The quadratic formula tells you the roots of that factor are
... x = (-b±√(b²-4ac))/(2a) = (3±√29)/2
The appropriate choices are
... C. (3-√29)/2
... D. (3+√29)/2
... F. 3
_____
The quadratic formula tells you the solution to
... ax²+bx+c=0
is x = (-b±√(b²-4ac))/(2a)
We have a=1, b=-3, c=-5.
I don’t know what u need to look for but I think for y
4y+7>-x-3
4y>-x-10
y>-1/4x-5/2
1. To solve this problem, you must apply the formula for calculate the area of the trapezoid, which is:
A=(B+b)h/2
A is the area of the trapezoid (A=69.6 in²).
(B+b) is the sum of the bases of the trapezoid.
h is the height of the trapezoid (h=8.7 in).
2. When you clear the sum of the bases (B+b), you have:
A=(B+b)h/2
2A=<span>(B+b)h
</span><span> (B+b)=2A/h
</span> (B+b)=2(69.6 in²)/(8.7 in)
(B+b)=16 in
3. The problem says that <span>the sum of its legs is equal to the sum of its bases, therefore, the perimeter is:
</span>
Sum of the legs=Sum of the bases (B+b)=16 in
Perimeter=16 in+16 in
Perimeter=32 in
This is so hard im so sry i dont get it
Answer:
Inverse of F does not exist
Step-by-step explanation:
2 different x values lead to 1 y value therefore it cannot be reversed
