Answer:
x= - 9/28 ± √60/7
Step-by-step explanation:
Answer:
x = 18
Step-by-step explanation:
the inequality is 9
1/2x.
if x = 18, the inequality is true.
9
1/2(18)
4:1.
56,000÷2 = 28,000
14,000÷2 = 7,000
28,000/7,000 = 28/7
28 ÷ 7 = 4
---- -----
7 ÷7 = 1
4:1
Hope this helps!
Answer:
![f(x)=x^2+8x+15](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B8x%2B15)
Step-by-step explanation:
If the function f(x) has x-intercepts of -3 and -5 then the roots are
and
.
The factors of this function are
and
.
We can write the function in factored form as:
![f(x)=(x+3)(x+5)](https://tex.z-dn.net/?f=f%28x%29%3D%28x%2B3%29%28x%2B5%29)
We expand using the distributive property to get:
![f(x)=x^2+5x+3x+15](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B5x%2B3x%2B15)
![f(x)=x^2+8x+15](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B8x%2B15)
