Answer:
c > -¼
Step-by-step explanation:
x² + 3x = 2x + c
x² + x - c = 0
Since they intersect at 2 points,
B²-4AC > 0
(1)²-4(1)(-c) > 0
1 + 4c > 0
C>-1/4
Two have intersection it must be:
2x+c= x^2+3x, i.e,
x^2+x-c=0
Solution of its equation is:
If we we want two solution we must have that:
1+4c>0
So c>-1/4.
C. 62
ADC is 90 degrees. 90 - 28 = 62
1. keep the same
2. y=3/2y-13

A defines the function
f(1) = - 8 ×( = - 8 × 1 = -8
f(2) = - 8 ×( = - = - 20
f(3) = - 8 ×( = - 8 × = - 50
f(4)= - 8 ×( = - 8 × = -125
f(5) = - 8 ×( = - 8 × = -
