Find the solution of the system of equations.

Mathematics
1 answer:
Alexandra [31]2 years ago
5 0

Answer:

x = -3

y = 9

Step-by-step explanation:

Add two equations up

4x + 5y - 9x - 5y = 33 - 18 add or subtract like terms

-5x = 15 divide both sides by -5

x = -3 we can use this information to find the value of y

4x + 5y = 33 replace x with -3

4 * (-3) + 5y = 33

-12 + 5y = 33 add 12 to both sides

5y = 45 divide both sides by 5

y = 9

snow_tiger [21]

Answer:

<h3>The value C(t) of the car after  5  years is $12709.</h3>

Step-by-step explanation:

Given that Landon bought a new car for $16,000 and it depreciates 4.5% every year.

<h3>To find the value C(t) of the car after  5  years:</h3>

Initial value C(0)= $16,000

Depreciation rate is  r=\frac{4.5}{100}

<h3>∴ r=0.045</h3>

Period ,  t=5 years

C(t)=C(0)(1-r)^t

Substitute the values we get

C(5)=16000(1-0.045)^5

=16000(0.955)^5

=16000(0.7943)

∴ C(5)=12708.8

<h3>The value C(t) of the car after  5  years is  $ 12709</h3>

On a quiz, students were awarded a certain number of points for a correct answer and penalized a certain number of points for an
SVETLANKA909090 [29]
Given that the score of the student on the quiz was 25c - 10(15 - c)

It can be seen that the first term of expression for her score (i.e. 25c) shows that 25 marks were awarded to each correct answer.

The second term of the expression (i.e. 10(15 - c)) represent that 10 marks were deducted from each wrong answer.

Thus, the number of wrong answers is 15 - c.

The sum of the correct answers and the wrong answers gives the total number of questions in the quiz.

Thus, the total number of questions in the quiz is given by 15 - c + c = 15.

Therefore, there are 15 questions in the quiz.
