I think maybe the answer is probably 7. Hope this helps !!
Answer:
- x=8, x=2
- no solution
- no solution
Step-by-step explanation:
For the equation ...
y = a(x -h)² +k
you can find the x-intercepts by setting y=0 and solving for x.
0 = a(x -h)² +k
-k = a(x -h)² . . . . . . subtract k
-k/a = (x -h)² . . . . . divide by a
±√(-k/a) = x -h . . . . take the square root
h ± √(-k/a) = x . . . . add h . . . . this is the general solution
__
So, for each of your problems, fill in the corresponding numbers and do the arithmetic. If (-k/a) is a negative number, the square root gives imaginary values, so there is "no solution".
1. x = 5 ± √9 = {5 -3, 5 +3} = {2, 8} . . . . the x-intercepts are 2 and 8
2. x = -3 ± √(-2) . . . . . . no solution; the roots are complex
3. x = 5 ± √(-8/4) . . . . . no solution; the roots are complex
Answer:0,1
Step-by-step explanation:
1 is the number in the x column that is in the same area as 0 they r vertical to each other
Given:
pi is equal to 3.14
3.14 ÷ 2/3
Rules in dividing fractions.
3.14 is the 1st fraction. It has a denominator of 1. 3.14/1
2/3 is the 2nd fraction
1) get the reciprocal of the 2nd fraction.
2/3 ⇒ 3/2
2) multiply the 1st fraction to the reciprocal of the 2nd fraction
3.14 * 3/2 = (3.14*3) / 2 = 9.42 / 2 = 4.71
Pi divided by 2/3 is 4.71
