Meredith is playing games at an arcade to earn tickets that she can exchange for a prize. She has 294 tickets from previous visi

t, and she earns 7 tickets for each game she plays in the equation below, x represents the number of games Meredith plays and y represents the number of tickets she needs for the prize.
y= 7x + 294

If Meredith needs 448 tickets to exchange for the prize she wants, how many games does Meredith need to play?


A. 106

B. 19

C. 64

D. 22

First, plug in 448 for y:

448=7x+294

Secondly, subtract 294 from both sides to isolate x:

154=7x

Divide both sides by 7:

22=x

Refine:

x=22

The answer is D)22

An easy way to do this is by plugging in all the answers until you get your answer
y=7(106)+294
y=742+294
y=1036
She doesn't need this many tickets to get the one prize, so this is false
y=7(19)+294
y=133+294
y=427
This cannot be true, because you need to have 448 tickets
y=7(64)+294
y=448+294
y=742
This is still over the amount of tickets that she needs, so this isn't true
y=7(22)+294
y=154+294
y=448
This is exactly the number of tickets that she needs, so this is true
So the answer is D

cora says she doesn't need to know the y-intercept of a line to write its equation, just its slope and some other point on the l
Nadusha1986 [10]

Answer:

The equation of line with given slope that include given points is                 3 y + x - 20 = 0

Step-by-step explanation:

According to Cora , if we know the slope and points on a line then we can write the equation of a line .

Since , The equation of line in slope-intercept form is

y = m x + c

<u>Where m is the slope of line , and if we know the points ( x , y ) which satisfy the line then constant term c can be get and the equation of line can be formed .</u>

So , From the statement said above it is clear that she is correct .

Now , Again

Given as :

Slope of a line is m = - \frac{1}{3}

That include points ( 2 , 6 )

Now from the equation of line as  y = m x + c

∴   6 =  - \frac{1}{3} ( 2 ) + c

Or, 6 =  - \frac{2}{3}  + c

So , c = 6 + \frac{2}{3}

or,  c = \frac{18 + 2}{3}

∴   c = \frac{20}{3}

So, The equation of line can be written as

 y =   - \frac{1}{3} x + \frac{20}{3}

Or, 3 y = - x + 20

I.e  3 y + x - 20 = 0

Hence The equation of line with given slope that include given points is     3 y + x - 20 = 0   Answer

Solving for an Unknown Using the Distributive Property
ArbitrLikvidat [17]

<em><u>Complete Question:</u></em>

The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?

<em><u>Answer:</u></em>

The numerator of fraction is -360

<em><u>Solution:</u></em>

Given that,

<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>

a = \frac{180(n - 2)}{n}

We have to solve the equation for "n"

Rearrange the equation

a \times n = 180(n - 2)\\\\a \times n = 180n - 360\\\\an - 180 n = -360\\\\Take\ n\ as\ common\ factor\\\\n(a-180) = -360\\\\n = \frac{-360}{a - 180}

Thus the numerator of the fraction is -360

Given the graph, find an equation for the parabola.
Sauron [17]

Answer:

\Large \boxed{\sf \bf \ \ y=\dfrac{1}{16}(a-3)^2-2 \ \  }

Step-by-step explanation:

Hello, please consider the following.

When the parabola equation is like

y=a(x-h)^2+k

The vertex is the point (h,k) and the focus is the point (h, k+1/(4a))

As the vertex is (3,-2) we can say that h = 3 and k = -2.

We need to find a.

The focus  is (3,2) so we can say.

2=-2+\dfrac{1}{4a}\\\\\text{*** We add 2. ***}\\\\\dfrac{1}{4a}=2+2=4\\\\\text{*** We multiply by 4a. ***}\\\\16a=1\\\\\text{*** We divide by 16. ***}\\\\a=\dfrac{1}{16}

So an equation for the parabola is.

\large \boxed{\sf y=\dfrac{1}{16}(a-3)^2-2 }

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
