Answer:

Adult: 50 tickets

Child: 34 tickets

Step-by-step explanation:

Let a be the amount of adult tickets

Let c be the amount of child tickets

Equation:

a + c = 84

14a + 9c = 1,006

Step 1: Multiply a + c = 84 with -9, to canceled c.

-9 (a + c = 84) → -9a - 9c = -756

14a + 9c = 1006 → 14a + 9c = 1006

Step 2: Combined the 2 equation together, and solved it.

-9a - 9c = -756

14a + 9c = 1006

5a = 250

5 5

a = 50

Step 3: Plug 50 into the one of the equation, and solved it.

a + c = 84 → 50 + c = 84

-50 -50

c = 34

Answer: Adult tickets (a) = 50 and Child tickets (c) = 34

To check the answer plug the two number into the equation ( Make sure to add 50 for a and 34 for c).

Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no

aliina [53]

9514 1404 393

Answer:

2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the unshaded area the solution space. Here, the vertices of the triangular solution space are ...

(2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

Three solutions are shown:

(x, y) = (2, 9), (3, 10), (4, 11)

Match each as either linear or non-linear. HELP

Virty [35]

Answer:

Linear

y=-x

$y = \frac{x}{9}$

$- \frac{2}{3}x + 3y = 1$

Non linear

$y = \frac{4}{x}$

$\frac{2}{y} = x$

${x}^{2} + {y}^{2} = 1$

Step-by-step explanation:

Linear equations have the highest degree to be 1.

Therefore y=-x is linear.

$y = \frac{x}{9} \: is \: also \: linear.$

$y = \frac{4}{x} \implies \: xy = 4$

The degree of this equation is 2.

It is non-linear

$- \frac{2}{3}x + 3y = 1$

is also linear.

$\frac{2}{y} = x \implies \: xy = 2....non - linear$

${x}^{2} + {y}^{2} = 1.....non - linear$
