The answer is AB= 4.62; mA= 22; mB=68
You could quickly find the answer by just using Pythagorean theorem to find AB.
4.3^2 +1.7^2 = AB^2
Answer:
m = -4.33333 or -4 and 1/3
Step-by-step explanation:
gradient = (difference in y)/(difference in X)
m = (-1-12)/(8-5)
m = -13/3
m = -4.3333333
To solve, start with this equation

So, 8 times 3 gives you how long they spent on art and 8 times 4 gives you how long they spent on science. So they spent...

25 is the answer to question 4 traveld by a passenger in one full rotation
Answer:
x = -4, x = 1
Step-by-step explanation:
x^2 + 3x - 4 = 0
4 and -1 add to 3 and multiply to -4.
(x+4)(x-1) = 0
Separate these by the Zero Product Property.
x+4 = 0
x-1 = 0
Solve.
x = -4
x = 1
