Directions: You probably see them in the news all the time—predictions about
prices, jobs, stocks, and other aspects of the economy. Now it's your turn to predict
the future! Follow the directions to make and explain an economic prediction for an
article you have been asked to write in the Economic News.
1. Choose one item of interest to you in the Historical Pricing Chart on the next
page.
2. Calculate the percent of change of the item's price each decade, and use
your results to determine the average rate of change from 1960–2000.
3. Comment on the trend in your item’s percent of increases.
4. Go shopping! Find the average current price of your item online, in the
newspaper, or locally by looking at the price when you go to the store in the
next day or two. Does the current price match the trend from 1960–2000
that you identified? Explain your thinking.
5. Create a line graph or other visual model to show the pricing trend. Be sure
to include the current price in your model.
6. Predict the item's price at a future date. Use your calculations and visual
model to justify your prediction.
7. Organize your analysis, prediction, explanations, and visual model in a brief
news article. Your completed article will be submitted as your portfolio
Answer:
. Predict the item's price at a future date. Use your calculations and visual
model to justify your prediction.

Sabrina can spend at most $5, including tax, to buy 3 cards. She finds 2 cards priced at $1.25 each and 1 card priced at $1.99, not including tax. Which inequality could be used to determine the amount of money, in dollars, Sabrina can afford to spend on tax (x) when she buys the 3 cards?
2(1.25+1.99)−x≥5
2(1.25+1.99)−x≤5
2(1.25)+1.99+x≤5
2(1.25)+1.99+x≥5
Answer:
2(1.25)+1.99+x≤5
Step-by-step explanation:
Because it says "at most $5" that means it would be either 2(1.25+1.99)−x≤5
or 2(1.25)+1.99+x≤5, which narrows it down to two. The reason it is the second option is because she is only buying two cards that cost $1.25, hence this part of the equation: 2(1.25) +1.99+x≤5.

7. -17+2(1+3x)=x-5(3-x) ANSWER: __________
no solution
infinitely many solutions
8. -2(x+4)+9x=4+7x ANSWER: __________
no solution
infinitely many solutions
Answer:
7) 4
Step-by-step explanation:
-17+2(1+3x)=x-5(3-x)
-17+2+6x=x-15+5x
-17+6x=x-15+2+5x
-17+6x-5x=x-13
x=x-13+17
x=x+4
x-x =4

Write another ratio that is equivalent to the ratio 4 : 6.
Answer:
8 : 12
Step-by-step explanation:
to get equivalent ratio multiply both numerator and denominator should be multiplied with same number
4 : 6
=> 4*2 : 6*2
=> 8 : 12
Answer:
2 : 3
Step-by-step explanation:
4 = 2 × 2
6 = 2 × 3
4 : 6
= 4 / 6
= ( 2 × 2 / 2 × 3 )
= 2 / 3
= 2 : 3

Answer:
F = 212
Step-by-step explanation:
F = 9/5 C +32
Let C = 100
F = 9/5 (100) +32
F = 180 +32
F = 212
Answer:
212 degrees Fahrenheit
Step-by-step explanation:
100 degrees Celsius times 9/5 is 180. If you add the 32 it comes out as a total of 212 degrees Fahrenheit.
help please and thankssssss.
Answer:
x = 20
Step-by-step explanation:
Hope this helps!
Answer:
X = 20 degrees
Step-by-step explanation:
1.) Form Equation. Since M is parallel to N and both lines are being cut by transversal T, we can say that the alternate exterior angles are congruent, so we know that 7x - 3 = 6x + 17.
2.) Isolate x. Move all the x to one side and all of the numbers to another side by subtracting by 6x on both sides and adding by 3 on both sides. You will get that x = 20 degrees.

1 and 2 reason: Use rise over run to find slope and y-intercept is where it crosses on y-axis.
What is the equation of the line in slope-intercept form for (0,4) and (4,2).
y=
Answer:
y = [tex]\frac{-1}{2}[/tex]x + 4
Step-by-step explanation:
Slope-intercept form: y = mx + b
[] m is the slope
[] b is the y-intercept
Slope
We can find slope by using change in y over change in x:
[tex]\frac{2-4}{4-0}=\frac{-2}{4}=\frac{-1}{2}[/tex]
[] So our slope is [tex]\frac{-1}{2}[/tex]
(since the line is negative, we can tell the line is going downwards from top-left to bottom-right)
Y-intercept
We will plug in one of the points into our equation so far, and solve for b:
y = [tex]\frac{-1}{2}[/tex]x + b
(2) = [tex]\frac{-1}{2}[/tex](4) + b
2 = -2 + b
4 = b
