ANSWER: x=7, y=19
Steps
1. Substitute y=2x+5
3x+2x+5=40
2. For y=2x+5 , Substitute x=7
y=2 * 7+5
3. 2 * 7+5=19
y=19
You know if something is a function or not because of the X will not be repeated. If it is, then it's not a function.
A. 0 and 2 are repeated in X
B. Nothing is repeated for X
C. 2 and 3 are repeated for X
D. 2 and 3 are repeated for X
B is your answer
Answer:
−2x^2+6x
Explanation:
You just have to distribute meaning you have to multiply -2x to the equation.
Answer:
800m
Step-by-step explanation:
this would be solved using Pythagoras theorem
we are to find the base
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
600² + b² = 100²
b² = 10000 - 3600
b² = 6400
take the square root of both sides
b = 800m
