what is the slope of the line ?
Answer:
The slope is 3/4 or 0.75.
Step-by-step explanation:
Let's take two points on a line. (-3,2) and (1,-1).
Now, determine the rise and run.
Rise: 3 Run: 4Slope = Rise/Run
=> 3/4Conclusion:
Therefore, the slope is 3/4 or 0.75.

study well:)
Answer: Deopends. See below.
Step-by-step explanation:
-5/12 from 2
The question is poorly worded. Is it asking us to subtract -5/12 from 2? Or are we being asked to subtract 5/12 from 2?
Assuming the first:
2 - (-5/12)
2 + 5/12
2 5/12 or 24/12 + 5/12 = 29/12
Assuming the second:
2 -5/12
24/12 - 5/12
19/12
Marta bought c CDs for $ 12 each, b books for $ 7 each, and a bag for $ 24 to.
Write an expression to show the total money Marta spent.
If Marta bought 4 CDs and 3 books, how much did she spend?
Answer:
A, 12c + 7b + 24
B, $69
Step-by-step explanation:
Please, read my picture Thanks! Also tell me if its right in the comment
4 * 12 + 3 * 7 + 24 = m
m represents how much money Marta spent
48 + 21 + 24 = m
69 + 24 = m
$93 = m

Answer:
f(x) is linear
g(x) is exponential
Step-by-step explanation:
A linear function will always have the same rate of change between equally distant points, while an exponential function will have an increasingly large rate of change between equally distant points.
First, look at f(x). All these points are equally distant at 2 units apart on the x-axis, so they can be directly compared:
[tex](-38)-(-18)=-20\\(-58)-(-38)=-20\\(-78)-(-58)=-20[/tex]
All of these points are the same distance apart on the y, so f(x) must be a linear function.
Now look at g(x). These are also all equally distant at only 1 unit apart.
[tex]30-10=20\\90-30=60\\270-90=180[/tex]
These are very clearly not the same distance apart on the y, so g(x) must be the exponential function.

explain how 984/616=123/77
Answer:
984/616 is equal to 123/77 because it is simplified, also meaning reduced by finding the GCF (greatest common factor), which in this case is 8. So therefore, when you divide the numerator of 984 by 8, you get 123, and when you divide the denominator of 616 by 8 as well, you will get 77.

Answer:
12
Step-by-step explanation:
So Josh is 6 years older than kims age and the sum of the ages is less than 31, the greatest number that is less than 31 is 30 so we can use that.
We can make an equation out of this and solve it.
n+(n+6)=30
2n+6=30
2n=24
n=12
12 is the oldest Kim could be.
12+(12+6)=12+18=30.

A number is at least 65
On < 65
On > 65
On > 65
On < 65
Answer:
n ≥ 65Step-by-step explanation:
A number is at least 65. It means the number n can be 65 or greater.
Its translation is:
n ≥ 65The answer options don't have this included.
Let the number be n
At least 65 means the number is equal to 65 or greater than 65.Hence here we use greater than equal to sign.Inequality:-

the data set represents the total number of tickets each person purchased for a play. 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 what is the median of the data? 1 1.5 2 2.5
The median of the data 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 is 1.5
There are three measures of central dispersion:
Mean: This is the average of the given data in the distribution.Median: It is the middle value of the set when the set is either arranged in ascending or descending order.Mode: This is the value that has the largest occurrence in the distribution.Given:
0, 0, 1, 1, 1, 2, 2, 2, 4, 4
The are 10 values in the data
So, we have two middle values: 1 and 2
Median = (1 + 2) / 2
= 3/2
= 1.5
Therefore, the median of the data 0, 0, 1, 1, 1, 2, 2, 2, 4, 4 is 1.5

Find e and d
3e+d=8
2e+d=8
Answer:
Step-by-step explanation:
Find the first three term if the general nth term is T = 2-n
Tn = 2n - 6
to find first term ,n= 1
substitute n for 1 in the equation
T1 = 2(1) - 6
T1 = 2 - 6 =-4
to find second term , n =2
substitute n for 2 in the equation
T2 = 2(2) - 6
T2 = 4 - 6 = -2
to find third term, n = 3
substitute n for 3 in the equation
T3 = 2(3) - 6
T3 = 6–6 = 0
FIRST TERM = -4
SECOND TERM = -2
THIRD TERM = 0

What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
Scale of the drawing : Length in meters is in the ration 3 cm : 4 m
Length of the soccer field is 108 m
Now , length of 108 m soccer field in scale of drawing = x
From proportion formula , we can deduce that
3 : 4 : : x : 108
So ,
3/4 = x/108
Multiply by 108 on both sides , we get
( 3 x 108 ) / 4 = x
x = 3 x 27 cm
x = 81 cm
Hence , length of the field in the drawing is 81 cm
