L (0,-4)
g (2,-4)
Identify the range of the data set 24, 36, 18, 42, 30 *
24
Arrange the data set into numerical order...
18, 24, 30, 36, 42
Subtract the lowest number from the top
42 - 18 = 24
I need help with this problem, if you could describe how to do it thats fine aswell, but im a little confused with this
Answer:
That it's confusing to you is understandable, these problems are confusing, They take a bunch of real world things and put it into abstract concepts. The graph of the line is just that, an idea of how math represents the cost of the milk.
Step-by-step explanation:
the graph you are given is a straight line, not all graphs are straight lines, but b/c it's a straight line we get to "categorize" it as linear. linear graphs are nice to work with, as compared to curvey ones. aka non-linear. There are a few famous formulas that go along with linear graphs. Remember graphs are just representations of info in a way that we can use math to understand that real thing in abstract ways.
the problem asks what is the slope of the line. Think of the idea of a mountain slope here, when we look at the graph.. and move over it like we would read, from left to right, the graph moves up hill.. or positive, so this graph is a positive slope graph. now we just need to figure out a way to say that with numbers.
often times slope is represented with the variable 'm' . why 'm' you ask? it's just a convention, it's not important which letter you use to represent slope but by convention we use 'm' There is a formula for slope that goes like this,
m = (y2-y1) / (x2-x1)
we can use that to find the slope of this line, but we already know it's positive just by quickly looking at the graph.
the x's and y's in the formula are the x and y points of some exact point on the graph that we can find just by looking at the graph. :) yes we get to make our own points. P1 and P2 ( point 1 and point 2)
somebody has already made two nice black dots, on your graph for you, let's use those two black dots, you don't have to, but those do look convenient. :)
using those two black dots and going from left to right.. I see the 1st point as P1 = (x1,y1) =( 2,10) and the second point as P2 = (x2,y2) = (4,20)
then plug those into the above fomula
m = (20-10) / (4-2)
m = 10 / 2
m = 5
yep, it's positive and steep up , that the answer to (a)
for (b)
we just need the formula called the point slope
y = mx + b
since we know m
y = 5x + b
for use b = 0
so just
y = 5x
now plug in x= 1/2, for the 1/2 gallon of milk
y = 5(1/2)
y = 2/5
that's (b) :)

B. y = [tex]\frac{1}{2}[/tex]x – 1
C. y = [tex]\frac{1}{2}[/tex]x + 1

it rises 2
and moves right once

You deposit $5000 in an account earning 7.5% simple interest per year. How long will it take for the balance of the account to be $6500?
Answer:
4 years
Step-by-step explanation:
Given data
Principal P=$5000
Rate r= 7.5%
Final amount A=$6500
The expression for the simple interest is
A=P(1+rt)
Substitute
6500=5000(1+0.075*t)
6500=5000+375t
6500-5000=375t
1500=375t
t= 1500/375
t= 4 years
Hence, the time is 4 years

Answer: (x−3)(x+7)
Step-by-step explanation:

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)
=x^2+7x−3x−21
=x^2+4x−21
Answer:
A. X^2+4x-21
Step-by-step explanation:
(x−3)(x+7)

Convert the circle to standard form.
[tex] {9x}^{2} + {9y}^{2} + 18x + 9y - 36 = 0[/tex]
Answer:
(x + 1)² + (y + 1)² = (√6)²
Step-by-step explanation:
Group the x- and y- terms together:
9x^2 + 18x + 9y^2 + 9y = 36
Factor out the coefficient 9:
x^2 + 2x + y^2 + y = 4
Complete the square of x^2 + 2x and then do the same for y^2 + 2y:
x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4
Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:
(x + 1)^2 + (y + 1)^2 - 2 = 4
Collect the constant terms on the right side:
(x + 1)^2 + (y + 1)^2 = 6
Rewrite 6 as (√6)^2:
(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²
Completing the square is done as follows: x^2 + 2x
Start with x^2 + 2x
1. Take half of the coefficient of x, which results in 2/2, or 1
2. Square this result and add it to, and subtract it from x^2 + 2x
x^2 + 2x + 1 - 1
3. Rewrite the first three terms as the square of a binomial:
x^2 + 2x + 1 - 1 = (x + 1)² - 1.
Do the same for y² + 2y.
How do i know this answer to this question ?? Joe has a total of 94 stamps in his stamp collection. He collected 27 in April and 34 in May. How many did he collect in June?
Answer:
Stamp collected in June = 33
Step-by-step explanation:
Total stamp = 94
Stamp collected in April = 27
Stamp collected in May = 34
Stamp collected in June = x
Total stamp = April stamp + May stamp + June stamp
94 = 27 + 34 + x
94 = 61 + x
x = 94 - 61
x = 33
Stamp collected in June = 33

The graph of linear function g passes through the point (-3,-10) and has a slope of 2.
What is the zero of g.
Answer:
2
Step-by-step explanation:
when x is 2 y = 0.
lets start with writing the function's equation;
it has a slope of 2 so 2x + k = y
given in the question when x = -3, y = -10
so k = -4
y = 2x - 4, 0 = 2x-4 then x = 2
