resenting the balance, C, in the piggy bank, where w is the number of weeks.
A) C = 1.25w – 12.50
B) C = 1.25w + 12.50
C) C = –1.25w + 12.50

Amount now-bus=ballance
bus=number of weeks times how much taken out each time
12.5=amount now
bus=1.25w


C=12.50-1.25w
or
C=-1.25w+12.5

answer is C

For this case we have a function of the form:

c (w) = mw + b

Where,

  • <em>b: initial amount </em>
  • <em>m: weekly rate of change </em>
  • <em>w: number of weeks </em>
  • <em>c: total balance </em>

We have then that Avery has a total of $ 12.50 in her piggy bank at home:

b = 12.50

Each week she takes out $ 1.25 to ride the city bus:

m = -1.25

Substituting values we have:

c (w) = - 1.25w + 12.50

Answer:

an equation representing the balance, C, in the piggy bank, where w is the number of weeks is:

c (w) = - 1.25w + 12.50

Option C

Answer:  The answer would be letter A

slope (m)=-9/2

intercept on x-axis=56/9

intercept on y-axis=28

Explanation:

18x+4y=112

(18x)/112+(4y)/112=1

(x/1)/(56/9)+y/28=1

intercept on x-axis=56/9

intercept on y-axis=28

now, 4y=-18x+112

y=-9/2x+28

so, slope (m)=-9/2

Step-by-step explanation:

Move all terms that don't contain  y  to the right side and solve.

y =  28  −  (9 x) /(2)

-3/10 bigger or -0.3?
ExtremeBDS [4]

-3/10= -0.3

They are both the same amount. 3 tenths and 3 tenths!

Example:

2/100= 0.02 so 2/100 and 0.02 are equal! It is all about the denominator and where the decimal point will go: 10= 0.1 100= 0.01 and 1000= 0.001

An oblique square prism is shown. Which expression represents the volume of the prism? x(x – 2) cubic units x(x +1) cubic units
Sauron [17]

Answer:

x²(x-2)  or x²(x+1)

Step-by-step explanation:

Even though the figure showing the prism is missing, we can already make a few assumptions about how to answer the question.

It tells us that it is an oblique square prism. Using this information, we can assume that of the dimensions (length, width and height), length and width are assumed to be equal.

If the unknown dimensions needed to calculate volume are written as:

Volume = X x Y x Z  (and length and width are the same, we can simplify)

Volume = X² x Z

Hence we need a x² in our answer.

In order to narrow it down between the two remaining options, the diagram is needed. If the height is shorter than the length, then the answer would be x²(x-2), however if the height is longer than the length, then the answer would be x²(x+1).
