Answer:
1/3 is 20
4 is x
C
Step-by-step explanation:
Answer:
5) y = -8x -4
6) y = 2x + 3
Step-by-step explanation:
Slope is rise over run. For the first problem, you went down 8 and over 1 to your next point. Going down means you have a negative slope. -8/1 is 8. Your y intercept is where the line meets the y axis. The line meets the y axis at -4.
The line meets a new point every time it goes over 1 and up 2. Rise over run means 2/1. The line goes up so the slope is positive. The line meets the y axis at 3
Addition is the inverse of subtraction and multiplication is the inverse of division.
Ex: 1+1 = 2, 2-2 = 0
Answer:
81
Step-by-step explanation: A square has all sides the same so you just multiply 9×9
Have a great day and a awsome thanks giveing brake :)
Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
