Answer:

B.

Step-by-step explanation:

One way you could figure out if a graph is a function is by doing the vertical line test:

Put a vertical line across every x value, if there is more than one point within one of the lines, it is not a function.

4% of ___ days is 56days
Kay [80]
We calculate this like this:

\frac{4}{100} *x=56


where x is the desired number. 4 percent of x is 56
\frac{4} *x=56*100


here i multiplied both sides by 100

x= \frac{56*100}{4}


I divided both sides by 4, then on the left hand side only x is left!

x= \frac{56*25}{4}


x= 1400




The answer is 1400

10) Solve the problem below using any method. Define your variables and write out the two
irga5000 [103]

Answer:

Variables: r, s

Number of Regular Tickets: 215

Equations: 8r + 6s = 3580; r + s = 525

Number of Senior Tickets: 310

Step-by-step explanation:

10) Solve the problem below using any method. Define your variables and write out the two equations. Then solve the problem.

A movie theater sells regular tickets for $8.00 and senior tickets for $6.00. One evening the theater

sold 525 tickets and took in $3580 in revenue. How many of each type of ticket were sold?

let r = number of regular tickets

let s = number of senior tickets

Equations:

The first equation deals with money.

8r + 6s = 3580

The second equation deals with numbers of tickets.

r + s = 525

Use the substitution method.

Solve the second equation for r.

r + s = 525

r = 525 - s

Substitute 525 - s for r in the first equation.

8r + 6s = 3580

8(525 - s) + 6s = 3580

4200 - 8s + 6s = 3580

4200 - 2s = 3580

-2s = -620

s = 310

Now substitute 310 for s in the equation r = 525 - s

r = 525 - 310

r = 215

Variables: r, s

Number of Regular Tickets: 215

Equations: 8r + 6s = 3580; r + s = 525

Number of Senior Tickets: 310

Answer:

The following are the missing numerators to make the LHS = RHS

  46) 36 x³y²

  47) 24 (xy)³

  48) 5 (3x + 6)

  49) 6(3x - 2)

  50) 8m (m + n)

Step-by-step explanation:

I have attached how to derive the answer below.

Essentially, each case found what the denominator on the LHS was multiplied by to get to the denominator on the RHS. Then I multiplied the numerator by that same factor.
