Kevin and his children went into a restaurant and he bought $31.50 worth of hotdogs and drinks. Each hotdog costs $4.50 and each drink costs $2.25. He bought 3 times as many hotdogs as drinks. Graphically solve a system of equations in order to determine the number of hotdogs, x,x, and the number of drinks, y,y, that Kevin bought.

Answers

Answer 1

Answer:

6 hot dogs, 2 drinks

Step-by-step explanation:

let y = number of hot dogs

let x = number of drinks

system:

y = 3x

4.5y + 2.25x = 31.50   (standard form:  y = -1/2x + 7)

if you graph the system, lines intersect at (2, 6)

Answer 2

Answer:

y=1/3 x

y=-2x+14

(6,2)

6 hotdogs  and 2 drinks

The minute hand of a clock is 4 inches long. How far does the tip of the minute hand move in 35 minutes? If necessary, round the answer to two decimal places.

Answers

Answer:

14.66 inches

Step-by-step explanation:

Calculation for How far does the tip of the minute hand move in 35 minutes

The tip of a minute hand will always travels at 360 degrees in an hour ( 60 minutes)

Hence, the tip of the minute hand

distance will be calculated using this formula

Circumference of a circle=2*π*Radius* Clock Tip hand movement/Number of minutes per hour

Let plug in the formula

Circumference of a circle==2*π*4 inches*35 minutes/60 minutes

Circumference of a circle= =2*π*4 inches*0.58333

Circumference of a circle==14.659 inches

Circumference of a circle==14.66 inches (Approximately)

Therefore How far does the tip of the minute hand move in 35 minutes will be 14.58 inches

Solve the following system of equations using the elimination method. 6x – 5y = –1 –6x – 4y = 10

Answers

Answer:

x= -1 y= -1

Step-by-step explanation:

A polygon is graphed on a coordinate plane, with a vertex located at
a point represented by (x,y).
The polygon is dilated with a scale factor, a , with the origin as the
center of dilation. The dilated image of the polygon is larger than
the polygon.
Which statement is true?

Answers

Answer:

a is greater than 1

Step-by-step explanation:

Let the two polygons be represented as  A and B.

Where A is the original polygon and B is the image of A

Such that

Polygon A has vertex (x,y) and scale factor = a

From the question, we understand that polygon B is bigger than A

When the dilated image (polygon B) is bigger than the original image (polygon A), then the scale factor is greater than 1.

Take for instance.

One of the coordinate point of polygon A is (2,4)

The corresponding coordinate point of polygon B will be greater than (2,4) because a is greater than 1.

Take a as 2:

The corresponding point on Polygon B would be 2 * (2,4) = (4,8)

b) x^(2) + 1

c) 16

d) 1

Step-by-step explanation:

f(x) = x^(2)

g(x) = x + 1

a)

f(g(x))

input g(x) into f(x)

f(x+1) = (x+1)^(2)

= x^(2) + 2x + 1

b)

g(f(x))

input f(x) into g(x)

g(x^(2))

x^(2) + 1

c)

f(g(3))

Use the equation found in part a, substitute in 3 for x

(3)^(2) + 2(3) + 1

= 9 + 6 + 1

= 16

d)

Use the equation found in part a, substitute in 0 for x

(0)^(2) + 2(0) + 1

= 0 + 0 + 1
