Answer:
The slope of the line is 8.
Step-by-step explanation:
To solve this problem, we can use the formula for slope:
slope = m = (y2 - y1)/(x2 - x1)
If we substitute in two points from the table into this formula, we get:
slope = m = (11-3)/(1-0) = 8/1 = 8
Therefore, the slope of the line is 8.
We can also see this by looking at the table itself. Since both x and y are increasing together, we know that the slope should be positive. For every increase in 1 in x, y increases by 8; this confirms that the slope of the line is 8.
Hope this helps!

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets of information is given by b = 1500p where p represents the number of packets and b represents the number of bytes of information.
a. How many packets would be needed to transmit 30,000 bytes of information?
Answer:
20
Step-by-step explanation:
If you have 1,500 per package and you need to find how many you will need to get 30,000 all you have to do is divide 30,000 by 1,500 and you get 20 packages. So the final equation would be 30,000=1500(20)
HOPE THIS HELPS!
Answer:20 Packets
Step-by-step explanation:Each packet is worth 1500b so 30,000b/1500b gives you 20 packets
Lin has a drawing with an area of 20 in²
If she increases all the sides by a scale factor of 4, what will the new area be?
Answer:
320 in²
Step-by-step explanation:
Given that Lin has a drawing that has an area of 20 in², since Lin used a scale factor of 4 to increase all sides, therefore the new area would be increased by the following:
Square of scale factor of the side = scale factor of area
4² = scale factor of area
16 = scale factor of area
Multiply the original area by 16
20 × 16 = 320 in²

Karen used a birthday check her mother gave her to start a savings account. She plans to save $25 per
month as well. After 8 months, Karen has $250. Write and solve a linear equation to find the original check
amount from Karen's mother.
Answer:
Explanation:
Lets just say the amount her mom gave her is c
and the months is a
the equation would be
c + 25a = 250
we can plug in 8 for a, cause we know its been 8 months,
c + 25(8)= 250
then do the parentheses
c + 200 = 250
subtract the 200 to isolate the variable c
c = 50
then you get c = 50,
Karen's mom gave her a check for $50.
(why karen btw. i would never give $50 to a karen)
The linear equation to calculate the amount from Karen's mother is
A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the amount given to Karen by her mother be = A
Let the total number of months be = x
The value of x is = 8 months
The total amount Karen has after 8 months = $ 250
The amount Karen saves per month = $ 25
Now , the equation will be
Total amount Karen has after 8 months = amount given to Karen by her mother + ( amount Karen saves per month x total number of months )
Substituting the values in the equation , we get
250 = A + 25x
On simplifying the equation , we get
A + 25x = 250
when x = 8
A + 25 ( 8 ) = 250
A + 200 = 250
Subtracting 200 on both sides of the equation , we get
A = $ 50
Therefore , the value of A is $ 50
Hence , The linear equation to calculate the amount from Karen's mother is A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50

The length of a rectangle is 11 feet more than the width. If the perimeter is 46 feet, then what is the length of the rectangle, in feet?
Answer:
Hi there!
Your answer is:
The length is 17
Step-by-step explanation:
L= 11+w
P=46
perimeter formula:
W+W+L+L = P
W+W+(11+w)+(11+w) = P
First solve for W
4W+22 = 46
-22
4w=24
/4
w=6
Now plug in W for the L formula
l=11+w
L= 11+ 6
L=17
