x=11
Answer: D
Step-by-step explanation:
this is in y=Mx+ b form. M stands for the slope and b stands for the y intercept, or where the line intersects with the y-axis.
Going left to right, the line slopes downwards, therefore it is a negative Slope. This narrows down your answer to either a or d. the slope is -1 because you can only ever write x by itself if it means 1x. In this case it is negative so it would look like this: -x
for the y-intercept, simply look at where the line passes through the y-axis. In this case, it is positive 2.
your finished equation would be: y=-x+2

Answer: A is 32.5
B is 162.5
Step-by-step explanation:
so what i did was that i divided 65/13 and i got 5 and then i divided 5/2 and got 2.5 and then i multiplied 13 and 2.5 and got 32.5 and then i divided 32.5 and 2.5 and got 65 and then i multiplied 65 and 2.5 and got 162.5
