1. Rate of change is 2/5
2. Rate of change is 1.5
3. Rate of change is -1x
4.Rate of change is 1/4
Answer:
Step-by-step explanation:
y = mx + b
slope(m) = 1/4
(-1,-4)...x = -1 and y = -4
now sub and find b, the y intercept
-4 = 1/4(-1) + b
-4 = -1/4 + b
-4 + 1/4 = b
-16/4 + 1/4 = b
-15/4 = b
so the equation in slope intercept form is : y = 1/4x - 15/4
but we need it in general form : Ax + By + C = 0
y = 1/4x - 15/4.....multiply everything by 4 to get rid of fractions
4y = x - 15......subtract x and add 15 ...to both sides
4y - x + 15 = 0 <=== general form
Answer: Use the base times hight to get the hypotenuse
Step-by-step explanation:
Answer:
Square root of 15^2-9^2=12
square root 13^2-12^=5
hence cosθ = 5/13 not 13/5.

Explanation:</h2>
In this case, we have the following equation:
But we can write this equation as:
So this final result is a quadratic equation written in Standard Form (). We need to find the solutions to this equations, so let's use quadratic formula:
