Answer:
y=3x-2
Step-by-step explanation:
y = 3x+ 2 ; y= 3x - 2 is a system of equations with no solution.
Answer:
I think it's m=8, c=0.
Step-by-step explanation:
If c is not 0 then c=-1
Answer:
6 solutions.
Step-by-step explanation:
1 + 2 + 3 = 6,
1*2*3 = 6.
So a = 1, b = 2 and c = 3 will fit this identity, as would any other combination of the 3 values. That is a total of 6 possible solutions. It is 6 because there are 6 possible different arrangements of 1,2 and 3.
As a matter of interest, 6 is one of the set of 'perfect numbers' where the sum of all the factors equals their product. The next one is 28 but that has 5 factors so that would not fit.
Answer:
24
Step-by-step explanation:
The answer needs the volume of the original pyramid minus the small pyramid cut off.
Volume of pyramid = (area of base x height)/3
(12 x 6 x 14)/3 - (4 x 10 x 6)/3 = 256 m^3
The diagram is completely wrong so this problem is actually impossible to solve!
If you slice horizontally across a rectangular pyramid the ratios of the edges will remain constant.
The two rectangles are not the same shape! 12:6 is not the same ratio as 10:4
If the original pyramid in this question was sliced in half the top rectangle of the frustum would be 6 x 3.
In this diagram the height was reduced from 14m to 8m so the top 6m was removed.
If the base was 12 x 6 the top rectangle should be 6/14 smaller = 5.14m by 2.57m (not 10 x 4)
