Answer:
y=3/2x+-1
Step-by-step explanation:
the formula is y=mx+b
y is the total
m is the slope
x is what you're multiplying the slope by
b is the y intercept
Answer:
x = 10
y = 70
Step-by-step explanation:
By using the vertical angles theorem we know that x+ y +10 = 90, also simplified to x + y = 80
and 2x + y = 90
By using the substitution method on x + y = 80, it will be y = -x + 80
When you put into the equation 2x + y = 90 you will get 2x -x +80 = 90
Then it will simplify to x = 10
After that plug 10 into x + y = 80 to 10 + y = 80 and get y = 70
Answer:
3.2
Step-by-step explanation:
0.8(4) = 3.2
Answer: option B. 4 feet above water.
Explanation:
This is an example of the use of the integer numbers.
Integer numbers are positive, zero and negative numbers.
In this case, zero is used to represent the surface of the water. So, any positive number will be the position above water and any netative number will be the position below water. That is why, while - 4 represents the position of the dolphin below water, 4 represents the position 4 feet above water.
