Answer:
4
Step-by-step explanation:
We can start by seeing the difference between -4 and -8. They have a difference of 4, so the middle number is 2 because 4/2 = 2. So now we can start skip counting, there are 4 lines between -4 and the blue dot. So 4*2 = 8. -4+8=4. So our answer is 4.
Answer:
only at x= 0 and x= 1. They are not equal at x= 3.
Step-by-step explanation:
The functions are given by, and .
We will substitute the values of x. It gives the following table,
x= 0 f(0)= 2×0+1= 1 g(0)= 2×(0^2)+1= 1
x= 1 f(1)= 2×1+1= 3 g(1)= 2×(1^2)+1= 2+1 = 3
x= 3 f(3)= 2×3+1= 7 g(3)= 2×(3^2)+1= 18+1 = 19
So, from the graphs below and the calculations above, we have,
Hence, the function have equal values only at x= 0 and x= 1.
Answer:
x1=-3
x2=5
Step-by-step explanation:
25(x+3)(4x-20)=0
(x+3) x (4x-20)=0
x+3=0
4x-20=0
x=-3
x=5
