Answer:
6
Step-by-step explanation:
f(x)=x^2-5x+6
To find the y intercept, set x=0
f(0) = 0^2 -5(0) +6
f(0) = 6
The y intercept =6
Answer:
Step-by-step explanation:


Let me help you with this :)
John = x
Mike = y
x = 4 + 3y (4 more than 3 times)
x + y = 20 (we put the x above into this equation)
4 + 3y + y = 20
4y = 16 (we transfers the 4 on the left side to the right side and subtract it from the 20)
y = 4 (the answer is 4)
we use this for the equation:
x = 4 +3*4
x = 16
John is 16 years old and Mike is 4 years old :)
Answer: 4x² + 4x - 2 - 
<u>Step-by-step explanation:</u>
You can use either synthetic or long division. I am using synthetic division:
2x + 3 = 0 ⇒ x = 
| 4 10 4 -6
<u>| ↓ -6 -6 3 </u>
4 4 -2 -3 ← <em>-3 is the remainder</em>
↓ ↓ ↓
4x² +4x -2 ← <em>factored polynomial</em>
