If a line goes through the point (8,9) and has a slope of negative 3/4 what is the starting value?
scZoUnD [109]

I assume by starting value, you mean y-intercept. The y-intercept is 15

To find this, we need to use slope intercept form and the given information to find it.

y = mx + b ----> plug in the known values

9 = -3/4(8) + b

9 = -6 + b

15 = b

Therefore, the starting value is 15.

MA_775_DIABLO [31]

Answer:

3,813.33 \:  {cm}^{3}

Step-by-step explanation:

Volume of the space that is not occupied = Volume of cube shaped box - volume of soccer ball

=  {20}^{3}  -  \frac{4}{3}  \times 3.14 \times  {10}^{3}  \\  \\  = 8000 -  \frac{4}{3}  \times 3.14 \times  1000 \\  \\   = 8000 -  \frac{4}{3}  \times 3140 \\  \\  = 8000 -  \frac{12560}{3}  \\  \\  = 8000 - 4,186.66667 \\  \\  = 3,813.33333 \\  \\  = 3,813.33 \:  {cm}^{3}

4. Solve for j.<br> 8j-5+j=67<br><br><br> *Plz, plz, plz, show your work.*
ICE Princess25 [194]
To solve for j, the first step is to get rid of the -5 by adding it to both sides to get:
8j+j=72
Then, add like things, which would be 8j and j (aka 1j) to get:
9j=72
Finally, divide both sides by 9 to get the answer, which is:
j=8

A box turtle marcos found is 0.115 of a meter long.what is this length in expanded form
castortr0y [4]

We are given length of turtle marcos = 0.115 of a meter.

We need to write this length in expanded form.

We know we have, first digit on left side of decimal is the value of ones in place value chart.

On the right side of decmal we read numbers as Tenths, Hundredths, Thousandths, Ten Thousandths.

We have

0 at Ones place, then decimal, then 1 at tenths place, again 1 at hundredths place and then 5 at thousandths place.

0.115 = 0 + 1 tenth + 1 hundredth + 5 thousandths.

Or 0.115 = 0 + 0.1 + 0.01 + 0.005.

Therefore, final expanded form is 0 + 0.1 + 0.01 + 0.005.

What are the advantages and disadvantages of each representation for finding patterns and making predictions?
Taya2010 [7]

Answer:

The advantages & disadvantages of tables,graphs and words have been explained below.

Step-by-step explanation:

The 3 major representation for finding patterns and making predictions are;

1.Tables

2. Graphs

3. Words

This means we want to find the advantages and disadvantages of using tables, graphs and words for finding patterns and making predictions.

1) Tables: Advantage is that we will be able to directly see the exact effect of the input variable on the output. While the disadvantage is that it's very difficult to see patterns.

2) Graphs: Advantage is that we can easily see the pattern of the representation. However the disadvantage is that we can't see the exact values arising from the effect of the input variable on the output.

3) Words: The advantage is that we can describe the data values in clear terms. However, the disadvantage is that we can't get exact values from just the words.
