Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
Answer:
2826 inches^2
Step-by-step explanation:
The general formula for the total surface area of a regular pyramid is
T.S.A.=12pl+B
Where p represents the perimeter of the base, l the slant height and B the area of the base.
The perimeter of the base is.
p=2L+2W
P=2*10+2*9
P=20+18
P= 38 inches
The area of the base is.
B=10*9
B=90in^2
T.S.A.=12(38)(6)+90
T.S.A=2736+90
T.S.A=2826 inches^2
Hence the paper needed is 2826 inches^2
The answer for the question shown above, is: False.
The explanation is shown below:
You cannot <span> use the surface area formula for a right cone to find the surface area of an oblique cone, because the slant height of oblique cones is on undefined and the vertex is not over the center. </span>
Answer:
its a 13units
Step-by-step explanation:
Answer:
300
Step-by-step explanation:
To find the number of pamphlets we use the following:
we divide the total budget by the cost per pamphlet and then we will know how many of them he can make.
the total budget is:
and the cost per pamphlet:
so we make the division:
The senator can make 300 pamphlets with the budget that he has.
