Answer:

Hence, Graph B and C has ( 2 , 12 ) as its solution.

Step-by-step explanation:

Given:

Graph Plot for A {Black line in graph}

Graph Plot for B {Green line in graph}

Graph Plot for C {Red line in graph}

Graph Plot for D {Blue line in graph}

To Find:

Which pair of equations has (2, 12) as its solution?

Solution:

A solution of pair of line is the point which satisfies both the equation. Hence it is also the intersecting point of two lines.

Therefore,

Graph Plot for B {Green line in graph}

and

Graph Plot for C {Red line in graph}

has the point of intersecting on ( 2 , 12 )

Hence, Graph B and C has ( 2 , 12 ) as its solution.

Hello from MrBillDoesMath!

Answer:

Discussion:

-8 (17 - 12) / ( -2 (8 - (-2)) ) -

= -8 ( 5) / ( -2 ( 8+2)) as 17 -12 = 5 and -(-2) = +2

= -40/ ( -2 (10))

= -40/(-20) =

= +2

which is the third choice.

Thank you,

Can someone help me with this question ? Show steps please

Answer:

B) $\boxed{A_T=108\;in^2}$

Step-by-step explanation:

That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.

The first step is to find the area of both bases like this:

$A_B=2\left(\dfrac{b\cdot h}{2}\right)=b\cdot h=4\cdot 3\\\\ \boxed{A_B=12\;in^2}$

The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:

$A_L=b_1\cdot h_1+b_2\cdot h_2+b_3\cdot h_3\\A_L=8\cdot3+8\cdot4+8\cdot5\\A_L=24+32+40\\\boxed{A_L=96\;in^2}$

Finally, we sum both of the areas found to calculate the total area.

$A_T=A_B+A_L\\A_T=12+96\\\boxed{A_T=108\;in^2}$

So, the answer is option B).

3. The manager of a store marks up all the items by 10%. If x is the original price, which expression represents the new price w

goldenfox [79]

Answer:
1.1x
x + 0.1x

Step-by-step explanation:

The manager of a store marks up all items by 10%.

So, if the original price of any item is x, then increase for markup is 10% of x i.e. .
Hence, the expression that represents the new price with the markup is (x + 0.1x) = 1.1x.
