Answer:
The answer to your question is : f(-2) = 2
Step-by-step explanation:
Just look for -2 in the x- axis and look for some line or point, vertical to number two.
In your example you can find a point two units upward the x-axis.
angle 1 + angle 3 = 27 +43 = 70
angle 2 = 180-70 = 110
angle 2 + angle 4 = 180
180 -angle 2 = angle 4 = 180-110 = 70
angle 4 = 70 degrees
4/3 because 3/3 is 1 and 4/3 is 1 1/3
Answer:
Step-by-step explanation:
2x² + 3x + 3 = 20
⇔ 2x² + 3x + 3 - 20 = 0
⇔ 2x² + 3x - 17 = 0
<u>Using the Quadratic Formula to solve a Quadratic Equation</u> :
In the equation 2x² + 3x - 17 = 0
a = 2 , b = 3 and c = -17
Then
b² - 4ac = 3² - 4×2×(-17)
= 9 + 8 × 17
= 9 + 136
= 145
Then
b² - 4ac > 0
Then
Then
Answer:
y = 2x - 4
Step-by-step explanation:
We'll write our equation in y = mx + b form, with m being the slope and b being the y-intercept. We already know our slope, so we can replace m with 2 like this: y = 2x + b. But we don't know what b is. We can use the point (3, 2) to figure out b's value, since it has an x-value (3) and a y-value (2):
2 = 2(3) + b
2 = 6 + b
-4 = b
So we have y = 2x + (-4), or y = 2x - 4.
