Answer: 6
Solution: 2(4-3) + 2(5-3) = 8-6+10-6=6
The point-slope form:

m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).

Answer:
Step-by-step explanation:
First let's re-write the equation:
f(x) = 3x² - 5x + 4
If f(-2). then we can re-write the equation as:
f(-2) = 3(-2)² - 5(-2) + 4
We must solve for exponent first: (-2)² = 4
f(-2) = 3(4) - 5(-2) + 4
Then solve for multiplication:
f(-2) = 12 + 10 + 4
Finally addition:
f(-2) = 26
that means that in a function, if X = -2, then F is equal to 26
Answer:
a)45º
b)22º
c)22º
Step-by-step explanation:
Add Angle b and angle a (45+113) then subtract from 180º (because that is the total of all triangle angles) and you get 22º
