Alja [10]

Answer:

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

$s = 10|x - 4| + 50$

Required

Solve for x when s = 80

Substitute 80 for x

$80 = 10|x - 4| + 50$

Subtract 50 from both sides

$80 - 50= 10|x - 4| + 50 - 50$

$30= 10|x - 4|$

Divide through by 10

$\frac{30}{10}= \frac{10|x - 4| }{10}$

$3= |x - 4|$

Reorder

$|x - 4| = 3$

This can be split into

$x - 4 = 3$ or $x - 4 = -3$

Solve for x

$x = 4 + 3$ or $x = 4 - 3$

$x = 7$ or $x = 1$

Hence:

<h2>For x=2</h2>

$- 10(2) + y = 4$

$- 20 + y = 4$

$y = 24$

<h2>For x=1</h2>

$- 10( 1) + y = 4$

$- 10 + y = 4$

$y = 14$

<h2>For x=0</h2>

$- 10(0) + y = 4$

$0 + y = 4$

$y = 4$

<h2>For x=-1</h2>

$- 10( - 1) + y = 4$

$10 + y = 4$

$y = - 6$

<h2>For x=2</h2>

$- 10( - 2) + y = 4$

$20 + y = 4$

$y = - 16$

Please help i will give you brainliest and every yhing

Lina20 [59]

first subtract the last equation from the first. this gives:-

-x + y = -8 .....................(1)

Then multiply the first equation by 2 and add it to the 2nd equations This gives

9x = 18

so x = 2

and from equation (1) y = -8 + 2 = -6

Substituting for x and y in the second equation

z = (24 -5(2) -12) / 2 = 1

Answer is choice b.
