x {– 2y = 8

Answers

Answer:

([tex]\frac{31}{4} , \frac{-1}{8}[/tex])

Step-by-step explanation:

use substitution:

3x+2y=23

x=2y+8

plug in 2y+8 for x

3(2y+8)+2y=23

distribute:

6y+24+2y=23

combine like terms:

8y+24=23

solve the equation:

y=-1/8

substitute -1/8 for y:

x=2(-1/8)+8

solve the equation:

x=31/4

Sam drew a rectangle measuring 9 feet in length by 15 feet in width. If she wants to make a similar rectangle measuring 27 feet in length, what should the width be?

Answers

Answer:

Step-by-step explanation:

If sam made a rectangle 9 feet in length and 15 in width. And we already know the next rectangle is 27 feet we can divide it by 9.

27/9=3

Now that we know its 3x the normal size we can grab the 15 and multiply it by 3.

15x3=45

in short: the answer is 45

Luke Bryan said the following expressions are equivalent because of the
Distributive Property. Is he correct?
2( 2x2+ 6) = 2x2+ 1

Answers

Luke is not correct

You need to do the problem in order of PEMDAS, so start with parentheses

2 x 2 = 4 + 6 = 10
Distribute the 2 on the outside
2 x 10 = 20

On the other side of the equation start with multiplication

2 x 2 = 4 + 1 = 5

5 ≠ 10

Luke is not correct

Sam walked to a nearby shop to purchase a gallon of ice cream. The shop is 400 meters from his house, and it took him 4 minutes to get there. At the shop, it took 2 minutes to choose a flavor and purchase the ice cream. He walked home in 3 minutes, at a faster pace than before so the ice cream wouldn’t melt.

Draw a graph that models Sam’s distance from home (in meters) in terms of time (in minutes). Label the graph with appropriate intervals and units.

Answers

Answer:

see the attached graph

Step-by-step explanation:

The axes and units for the graph are given in the problem statement. The range of the graph is also given, but figuring the domain requires a little arithmetic. We assume the walking pace is constant, so the graph will be piecewise linear.

Axes

The vertical (y) axis is labeled with what the graph is modeling, "distance from home (in meters)." The horizontal (x) axis is labeled with what the model is in terms of "time (in minutes)."

The range of the graph is 0 to 400 meters, the range of distances Sam may be from home.

The domain of the graph is 0 to 9 minutes. The time it takes to complete the trip is 4 minutes to the shop, 2 minutes at the shop, and 3 minutes coming home, for a total of 4+2+3 = 9 minutes.

Graph

We are given that points on the graph will be (0, 0), (4, 400), (6, 400), and (9, 0). That is Sam is ...

at home at 0 minutes400 meters from home (at the shop) after 4 minutesremaining 400 meters from home for 2 more minutes (until 6 minutes)at home after 3 more minutes (at 9 minutes).

Since we assume walking is at a steady pace, we connect these dots with straight lines. The resulting graph is attached.
