Answer:

The correct answer is (-5,-5)

Step-by-step explanation:

1. Both of the equations are in standard form, so first you set them equal to each other.

2. Solve for x as a normal algebraic equation.

3. Back substitute your answer for x into one of the original equations. (back substitution is just putting the x back into the equation and solving for y.)

4. Now you have your x and y coordinates, and the point of intersection of the two lines.

What is the volume of the square pyramid? Round to the nearest tenth.

goldfiish [28.3K]

Answer:

$V=718.7\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

we have

$b=14\ cm$ ----> the length of the base of the square pyramid

$h=11\ cm$ ---> the height of the pyramid

substitute the values in the formula

$V=\frac{1}{3}(14)^{2}(11)$

$V=718.7\ cm^{3}$

Answer:

You must order the operations in the way that it unfolds in the explanation;:

Step-by-step explanation:

(25 x 9) +75 + 50+ 9 x ( 3 + 1)

When performing the operations we have the following results:

(25 x 9) =225 +75= 300+50 = 350+9 = 359 x (3+1 )

Now we must solve the following: 359 x (4) = 386
