A- 2b = 2 one of the 2 "A" most be negative so they can cancer each other
-a- b = 6 after the "A" cancel each other add the -2b with -b = -3b, then add 2
-------------- and 6
-3b=8 then you have to divide 8 by -3 = -2.6 -2.6 its b... now you have to solve for b step 1. a -2b = 2 step 2. a -2(-2.6)=2 step 3 a -5.3 = 2 then subtract -5.3 with 2 so that going to be 2 + 5.3 =7.3 then divide by a
final answer (-2.5,-7.3)
sorry its kinda hard to explained here, i hope you get the point :)
Answer: I think it is -x/8+2y/3+10
Step-by-step explanation:
Answer:
Rectangle is a 2dimensional shape so, let me explain using it
The diagonal of a rectangle divides the rectangle into two triangles that are congruent and they are the same size and shape.
Another example is parallelogram
The diagonal of a parallelogram also divides the figure into two triangles that are congruent.
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
You use the distributive property.
Distribute the 2 to whatever is inside the parentheses. (You will multiply)
4×2=8
2×6=12
Substitute the answers above into the parentheses.
(8+12)=20
Answer:
2.25
Step-by-step explanation:
to find slope it is (y2-y1)/(x2-x1)
(15.25-8.50)/(5-2)
6.75/3
2.25 is the slope
