The answer is neither. (X,Y) Plug them into the equation and neither is a solution to the equation.

Answer:

D, neither.

Step-by-step explanation:

If you substitute 1 in for x and 5 in for y, you will get 7-10=-5 and this is incorrect. If you substitute -1 in for x and 1 in for y, you will get -7-2=-5 and this is also incorrect. So the correct answer is D, neither. I hope this helps!

Given the expression
-2 + 6.45z - 6 + (-3.25z)

First, classify like terms, constant with constant, coefficient-variable with coefficient-variable
-2 + 6.45z - 6 + (-3.25z)
= 6.45z + (-3.25z) - 2 - 6

Second, combining like terms
= 6.45z + (-3.25z) - 2 - 6
= 6.45z - 3.25z - 8
= 3.20z - 8

The simplest form is 3.20 - 8

Wittaler [7]

Answer:

B. 20 years

Step-by-step explanation:

By using the process of trial and error, if Gina is 20 years old, that would mean her sister is 29 years old. This is because 20+9 is equal to 29. 29+20 sums up to 49.

Answer:

area = x(3x +10)

Step-by-step explanation:

The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.

horizontal unmarked = (2x+15) -x = x +15

vertical unmarked = (2x -5) -(x -5) = x

The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.

The whole area is ...

x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)
