Answer:
Step-by-step explanation:
<u>The function in vertex form:</u>
<u>x- intercepts are 15 and 35:</u>
- 0 = a(15 - 25)² + 32 or 0 = a(35 - 25)² + 32
- 0 = a*100 + 32
- 100a = - 32
- a = -32/100
- a = -8/25 or -0.32
For number 1.
Since AB + BC = AC
Then
-12x + 11 - 8x -4 = 127
-20x + 7 = 127
X = -6
Ab would then equal 83
60 Kilometers would be your answer
216. You do 216/3 to get what each fourth is worth you get 54 then add that to 162
The sum of 7 to the 9th power and y is expressed as 7⁹ + y
This statement will result in an exponential equation since we will have a base and an exponent
- 7 raise to the 9th power is expressed as 7⁹
- Taking the sum of the result and y;
- The final expression will be 7⁹ + y
Hence the sum of 7 to the 9th power and y is expressed as 7⁹ + y
