Answer:
4x+20
Step-by-step explanation:
Answer:
7
Step-by-step explanation:They all can be divided by 7
Part A: make slope-intercept form of equation
We will have variable y for the depth of the submarine after x hours. The start 1,500 will be written -1,500 because it's below surface of water.
The equation after x hours will be
y = -1,500 + 52x
y = 52x - 1,500
Part B: Find the depth after two hours
Change variable x with 2
y = 52x - 1,500
y = 52(2) - 1,500
y = 104 - 1,500
y = -1,396
Negative means it's below surface
Answer:
2
Step-by-step explanation:
xy/z where x = 3 y = -4 and z = -6
Step 1. Substitute x for 3 y for -4 and z for -6
(3)(-4)/(-6)
Step 2. Multiply
-12/-6
Step 3. Remove the negative signs (only when the numerator and the denominator are both negative numbers)
12/6
Step 4. Simplify
2
