Is (5,50) a solution to the linear system y = 5x + 25 and y = 3x + 35? Explain your reasoning.
IRINA_888 [86]

Answer:  Yes (5, 50) is a solution

========================================================

Explanation:

The point (5, 50) means x = 5 and y = 50 pair up together.

Plug those values into the first equation and simplify both sides as much as possible. This is so we have one number on each side.

y = 5x+25

50 = 5*5+25

50 = 25+25

50 = 50

Because we ended up with a true statement at the end, this makes the original equation y = 5x+25 to be true when (x,y) = (5,50).

In other words, the first equation has been confirmed.

---------

Repeat those steps for the second equation

y = 3x+35

50 = 3*5+35

50 = 15+35

50 = 50

We get another true statement, and we've confirmed the second equation.

Both equations are true when (x,y) = (5, 50)

---------

This fully confirms that (5, 50) is indeed a solution to this system.

It turns out it's the only solution. Visually we can verify this by looking at the graph. The two lines intersect at one location and it is (5, 50).

See below.

A car is purchased for $21,000. After each year, the resale value decreases by 35%. What will the
anyanavicka [17]

Answer:

8859.5

Step-by-step explanation:

if it decreases with 35% then after each year it is worth only 75% of its previous value. so after one year it is worth 75%*21000=15750. the next year it is 75%*15750=11812.2. and after the 3rd year itnis worth 75%*11812.2=8859.5

URGENT PLEASE HELP ME<br> what side is the adjacent and opposite
trapecia [35]

Answer: Line DE is the adjacent while line EF is the opposite.

Step-by-step explanation: This is a right angled triangle and the reference angle has been marked at point D. If you drew a line from that angle it would touch the triangle at line line EF. It’s facing the reference angle and that’s why it’s called the “opposite.”

The line that lies between the reference angle and the right angle is called the adjacent and that’s line DE in this triangle. The hypotenuse has already been identified for you, and that’s the line that’s opposite the right angle (it’s always the longest side).

**Please note that the opposite and adjacent ALWAYS depends on where the reference angle is positioned.
