2.) David has a fish tank shaped like a rectangular prism that is 10 inches by 20 inches by 10 inches. If
David only fills the tank of the way, what will be
the volume of the water in the tank?
a.) 500 inches
c.) 1,000 Inches
b.) 2.000 inches
d.) 40 Inches

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

they will manufacture 8496 cars

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
