Sandy: 10x + 5
Kimmi: 25x
If we want to know when the fees will be the same, we set the equations equal to each other and solve for x:
10x + 5 = 25x
5 = 15x
x = 3
So the number of children has to be 3.
Answer:
The correct option is A.
Step-by-step explanation:
The correct option is A.
If u notice the second transformation it would shift triangle ABC 3 units to the left and reflect it across x = 4 so this will not map ABC into DEF.
If u notice first transformation it will shift triangle ABC 7 units down and reflect it across x=4 so this will map ABC into DEF.
Thus option A is correct....
Answer:
(x + 2)² = 7
Step-by-step explanation:
We have to complete the square in the given equation
3x² + 12x = 9
3x² + 12x - 9 = 0
3[x² + 4x -3] = 0
3[x² + 2(2x) + 4 - 4 - 3] = 0
3[x² + 2(2x) + 4] - 3 × 7 = 0
3[x² + 2]² - 21 = 0
(x + 2)² = = 7
Therefore, the square form of the equation is (x + 2)² = 7
Hope this helps (:
Answer:
32
Step-by-step explanation:
f(x) = 3x²+5
f(-3) = 3(-3)^2+5 = 27 + 5 = 32
