Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $

775 from a combination of $5.00 quick washes and $8.00 premium washes.
Let x represent the number of quick washes and let y represent the number of premium washes. Which system of linear equations represents the situation?

The system of linear equations represents the situation is;

x + y = 125

x + y = 1255x + 8y = 775

<h3>Simultaneous equation</h3>

Simultaneous equation is an equation in two unknown values are being solved for at the same time.

let

  • number of quick washes = x
  • number of premium washes = y

x + y = 125

5x + 8y = 775

From equation (1)

x = 125 - y

5x + 8y = 775

5(125 - y) + 8y = 775

625 - 5y + 8y = 775

- 5y + 8y = 775 - 625

3y = 150

y = 150/3

y = 50

  • Substitute y = 50 into

x + y = 125

x + 50 = 125

x = 125 - 50

x = 75

Therefore, the number of quick washes and premium washes Monica’s school band had is 75 and 50 respectively.

Which function forms a geometric sequence when x = 1, 2, 3, ...?
jeka94
The geometric sequence is found in the relationship between consecutive terms that is constant.
 In this problem, as I understand it, none of the functions forms a geometric sequence.
 The functions that form a geometric sequence have the form
 f (x) = h (a) ^ n where "a" is the constant relation between the successive terms.
 If you wrote the function "f (x) = - 2 (3/4) x", you wanted to write instead:
 f (x) = - 2 (3/4) ^ x
 So that would be the function that forms a geometric sequence, where the relation between the consecutive terms is 3/4.
 You can test it by dividing f (x) / f (x-1)
 Then you will see that the result of that division will be 3/4.

Is this a right triangle? Hypotenuse is 15 adjacent is 9 and the opp is 12
scoray [572]

Answer:

Yes

Step-by-step explanation:

A right triangle's formula, according to Pythagorean's Theorem, is a² + b² = c². a and b are the two legs, and c is the hypotenuse. To solve, we must substitute the variables with the given measurements.

9² + 12² = 15²

Let's now solve:

81 + 144 = 225

225 = 225

The formula works out in the end, so it is a right triangle!
