Answer:
160
Step-by-step explanation:
Using Exterior angle theorem
30+130=160
Answer:
x = - 6
Step-by-step explanation:
The x-intercept is when y =0, you are looking for a point (x, 0)
So you replace y = 0 in the equation
4x - 3y = - 24
4x - 3(0) = - 24
4x = - 24
x = - 6

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x² - 7x
f(-2) is x = -2
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-2) = 3(-2)² - 7(-2)
- Exponents: f(-2) = 3(4) - 7(-2)
- Multiply: f(-2) = 12 + 14
- Add: f(-2) = 26
The the parabola opens upward it has a minimum and if it opens downward then it has a maximum :)
