Answer:
X= -5
Y=-2.7
Step-by-step explanation:
YOU DO THIS BY SUBTRACTING 25 ON THE RIGHT SIDE TO THE LEFT ONLY LEAVING YOU WITH VARIABLES.
THEN YOU SUBSTITUTE ZERO INTO Y TO FIND X THEN SUBTITUTE ZERO INTO X TO FIND Y
BTW SUBSTITUTE ONE INTO THE VARIABLE YOU ARE FINDING
Answer:
y=2x+1
Step-by-step explanation:
Parallel = gradients are the same
Example: y=2/4x+5
Perpendicular = gradients are the inverse of each other
Example: y= -4/2x+1
Any equation would be correct unless the gradient is 2/4 or -4/2
Answer:
Sorry i don't get this at all. what grade is this ?!!?!?!?
Step-by-step explanation:
Answer:
slope is -3
it is the only one that makes sense because the line goes through -3
Answer:
314 in²
Step-by-step explanation:
The formula for the area of a circle is pi*r² or pi (3.14...)* radius²(squared).
If you plug in the radius given into the equation, you get 3.14*10² you can then solve this using systems of equations.
3.14*10²
10² = 10*10
3.14*(10*10)
10*10= 100
3.14*100
3.14*100= 314
