Answer:
(-2,0) and (2,0)
Step-by-step explanation:
The x-intercepts are where the parabola touches the x-axis (aka when y is 0).
i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
Answer:
x = 4√2
Step-by-step explanation:
<u><em>Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem</em></u>
To solve, we will follow the steps below:
using Pythagoras theorem
opposite² + adjacent² = hypotenuse²
14² + y² = 18²
196 + y² = 324
subtract 196 from both-side of the equation
196 -196 + y² = 324-196
y² =128
Take the square root of both-side
√y² = √128
y =√128
y = √64×2
y =√64×√2
y = 8√2
x = half of y
x = y/2
x = 8√2 ÷ 2
x = 4√2
