<u>Part 1</u>
The gradient of the line is
, so the equation is
.
This means the system is
![y=-2x+5\\\\y=ax^2 +b](https://tex.z-dn.net/?f=y%3D-2x%2B5%5C%5C%5C%5Cy%3Dax%5E2%20%2Bb)
<u>Part 2</u>
Substituting in the coordinates (-3,11) and (2,1) into the equation of the parabola,
![11=9a+b\\\\1=4a+b](https://tex.z-dn.net/?f=11%3D9a%2Bb%5C%5C%5C%5C1%3D4a%2Bb)
Subtracting the equations, we get 10=5a, and thus a = 2
Substituting a = 2 back into the system, we get b = -7
<u>Part 3</u>
The equation of the parabola is
, and the turning point is at
. Therefore, the value of y is -7
Answer A. 15 glad to help
Answer:
theb correct answer is d VHow does your body’s flexibility naturally change as you age?
Step-by-step explanation:
What is the smallest number divisible by 3, 4, 32 and 9?
You might want to try factoring these denominators and writing them in their factored form:
3, 2^2, 2^5, 3^2
Your LCD must include the following factors: 3^2 and 2^5, or 9 and 32. Multiplying these together results in the correct LCD 9*32=288.
Check: Is 288 divisible by 3? Yes. The quotient is 96.
Is 288 divisible by 4? Yes. Is 288 divisible by 32? Yes. Is 288 divisible by 9? Yes.
