Answer:

See attached worksheet.

Step-by-step explanation:

See attached worksheet for the table and graph.

I assume that "functation notation: simply means using x and y:

y = 2x + 3

The relationship between the number of T-shirts and cost is defined by y = 2t + 3, where:

y is the total cost,

x is the number of t-shirts,

the 2 is the cost for 1 t-shirt ($/t-shirt), and

3 is a one=time charge of $3 for each order.

The graph (attached) shows a straight line with a y-intercept of 3, the initial order fee. It is linear since the cost of a t-shirt remains the same egardless of order size.

Answer:

n =7

Step-by-step explanation:

(n+1) +1 + (n-1) = value first row

3+ (2n-9) +n = value second row

The value has to be the same

Set the equations equal

(n+1) +1 + (n-1) =3+ (2n-9) +n

Combine like terms

2n+1 = 3n-6

Subtract 2n from each side

2n+1-1 -2n = 3n-6-2n

1 = n-6

Add 6 to each side

1+6 = n-6+6

7 = n

The point P= (x,-1/7) lies on the unit circle shown below. What is the value of x in simplest form?

ipn [44]

Answer:

$x^2 + \frac{1}{49} =1$

And solving for x we got:

$x^2 = 1- \frac{1}{49}$

$x^2 = \frac{48}{49}$

And taking square root we got:

$x = \sqrt{\frac{48}{49}}= \frac{\sqrt{48}}{7} = \frac{4\sqrt{3}}{7}$

Step-by-step explanation:

For this case we have the following point given $P(x , -1/7)$

And we want to find the value of x, since P lies on the unitray circle if we find the distance from P to the center of the unitary circle (0,0) we need to get 1. Using the definition of Euclidean distance that means:

$d = \sqrt{(x -0)^2 +(-1/7 -0)^2}=1$

And if we square both sides of the last equation we got:

$x^2 + \frac{1}{49} =1$

And solving for x we got:

$x^2 = 1- \frac{1}{49}$

$x^2 = \frac{48}{49}$

And taking square root we got:

$x = \sqrt{\frac{48}{49}}= \frac{\sqrt{48}}{7} = \frac{4\sqrt{3}}{7}$

Answer any of the following:

Volgvan

1. Solve the system by substitution -2x+y=-11, 3x-4y=11.
-2x+y=-11
y = 2x-11

3x-4y=11
3x-4(2x-11)=11
3x -8x + 44 = 11
-5x = -33
x =33/5
y = 11/5

2. Solve the system using elimination- 2x+6y=-12, 5x-5y=10.
(-2x+6y=-12)5
-10x + 30y = -60

(5x-5y=10)2
10x - 10y = 20

Adding the two equations,
-10x + 30y = -60
10x - 10y = 20

20y = -40
y = -2
x = 0

3. What is the solution of the following system?-3x-2y=-12, 9x+6y=-9.
-3x-2y=-12
y = -3/2 x + 6

9x+6y=-9
y = -3/2 x - 3/2

Since the slopes are equal then they are parallel lines so they never meet at one point.
