Answer: The answer is 7-b=-y
Step-by-step explanation: You subtract b from one side to the other, and then do the same with y
Answer:
area of arrow=610cm²
Step-by-step
First find the area of the square then the are of the triangle then add together to get the area of the arrow.
1.
Area=length x width
=20cm x 15cm
=300cm²
2.
Area= 1/2 base x height
=1/2 x 20 x 31
=1 x 10 x 31
=310cm²
(NOTE: TO FIND THE BASE YOU ADD THE 15CM FROM THE SQUARE AND THE 2 EIGHT'S FROM THE BOTTOM OF THE TRIANGLE)
3.
Total area or area of arrow
=300cm²+310cm²
=610cm²
Answer:
See attached picture.
Step-by-step explanation:
To graph the equation, use the slope intercept form of the line to identify the slope and y-intercept.
y = -x + 1 y = mx+b
m=-1 and b=1
This means start at 1 on the y-axis and plot a point. From this point (0,1), move down 1 unit and to the right 1 unit. Plot this point (0,1). Connect the two points.
True because you divide h with A which results A/h. Then you multiply 2 with A so you can cancel 1/2 to make it 1. There you get b= 2A/h
54 can be factored as follows:
54
2*27
2*3*9
2*3^2*3
2*3^3
Therefore, 54 is equal to 2*3^3, or 2*3*3*3.
