Answer:
A is false
Step-by-step explanation:
notice how in both diagrams, there are 4 triangles with lengths a, b, c, but in each diagram the triangles are just rotated and positioned differently. if there are the same amount of triangles in both diagrams, and the have equal lengths then the area of the remaining figure, should both match up.
basically the area of the big square in Step 2, is equal to both of the shaded squares, combined area, in Step 1.
Answer:
A
Step-by-step explanation:
I think it’s a based on what you given
Answer:
y-6 = -2(x+1)
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-2-6)/(3--1)
= (-2-6)/(3+1)
= -8/4
= -2
Then we can point slope form where
y -y1 = m(x-x1)
where m is the slope and x1,y1 is a point
y-6 = -2(x--1)
y-6 = -2(x+1)
Answer:
x = -2
Step-by-step explanation:
7x + 3 = -11
-3 -3 subtract both sides by 3
7x = - 14
7x/7 = - 14/7 divide both sides by 7
-14/7 = -2
Remark
This is an excellent question. Estimation is a powerful skill to have. People should always shop using estimates. Try it to see what happens.
x = 11.7 which rounds up to which we will call x1 and that is 12
y = 6.03 which round down to 6 which we will call y1 and that is 6
Now x - y = 5.67
If you do the rounded subtraction x1 - y1 = 12 - 6 = 6
The estimate is not zero. D is not correct.
There is enough information E is not the answer.
B is wrong, her estimate is larger than x - y
C is wrong the two subtractions are not equal.
A is correct and always will be no matter what numbers are chosen
