Answer: y=4x-3
Step-by-step explanation:
You need to find (change in y)/(change in x) to find slope. 4/1=4. So the slope is 4. Then find the y intercept which is (0,-3). So the equation in slope intercept form is y=4x-3.
y=4x-3

How can you divided a fractions
Answers
Answer:
I have explained below
Brief explanation:
To divide fractions take the fraction you're dividing by and turn it around. Then replace the division sign with a multiplication sign.
This is how it works - I'll illustrate with an example
[tex]\frac{1}{2} :\frac{2}{3}[/tex]
[tex]\frac{1}{2} : \frac{3}{2}[/tex]
[tex]\frac{1}{2} *\frac{3}{2}[/tex]
now just multiply over
[tex]\frac{1*3}{2*2}[/tex]

14) y=5
15) z=-8

18) 1, because [tex]2^{4}/{2^{4} =1[/tex]. Therefore [tex]2^{4}/{2^{4} = 2^{4-4}=2^{0}=1[/tex]
Step-by-step explanation:
12) Exponent Zero rule. Anything raise to 0 power equals 1.
13) Exponent Negative rule: [tex]b^{-n} =\frac{1}{b^n}[/tex]
14) Exponent Quotient rule: [tex](a^n/a^m)=a^{n-m}[/tex]
In this case, [tex](3^3/3^5)=3^{3-5}=3^{-2}=1/3^2=1/9[/tex]
15) Exponent Product rule: [tex](a^n*a^m)=a^{n+m}[/tex]
In this case, [tex](5^8*5^{-8})=5^{8-8}=5^0=1[/tex]
16) Same rule as #15, [tex](7^2*7^{-2})=7^{2-2}=7^0=1[/tex]
17)We can work backwards here, we know [tex]2^{2} = 4[/tex] and [tex]3^{1} =3[/tex], so we need [tex]2^2/3^1=4/3[/tex].
To achieve this, use Exponent Quotient rule, what x-4=1? x=5.
Similar base: [tex](3^5/3^4)=3^{5-4}=3^{1}=1/3[/tex]. Put [tex]2^{2}[/tex] back for [tex]\frac{4}{3}[/tex]
18) 1*1*1*1=1. Anything raise to 0 power equals 1 (Exponent Zero rule). To prove this, any number(except 0) divided by itself equals 1.
Ex: 1/1=1, 4/4=1, [tex]2^4/2^4=1[/tex].
We can prove this with the Exponent Quotient rule. [tex]1=\frac{3}{3} =\frac{3^1}{3^1}=3^{1-1}=3^0=1[/tex]. No matter how I write it, it's equal to 1.
The one exception is [tex]0^{0}[/tex], which is undefined, since dividing by zero is illegal.
Hope this helps. ;)

Solve. -11 2/3 x (-4 1/5)
A. 49
B. -49
C. 44 2/15
D. -44 2/15
Answers
convert -11 2/3 into and improper fraction and do the same things for -4 1/5.
so it will become. -35/3 x (-21/5).
TWO NEGATIVE EQUAL A POSITIVE.
35/3 x 21/5 - cancel out the greatest common factor 5
7/3 x 21 - cancel put the great common factor 3
7x7
= 49
How I solved it-
-11 2/3 x (-4 1/5)
I started with turning the mixed numbers into improper fractions, Which the new equation would be, -35/3 x -21/5
Then multiplied them and got 735/15 and then just divide 735 by 15 and you will get 49. Hope this helps!!
Tyrese wants to buy 15 packs of baseball cards. They cost $5.00 per pack. There is a 25% discount before tax if 10 or more packs are purchased. Sales tax is 7%. Tyrese gives the cashier $100 to pay for his baseball cards.
How much change will he receive in return?
Answers
Answer:
$39.81
Step-by-step explanation:
$5.00 per pack
15 packs
25% discount for 10 or more packs
7% sales tax
paid $100
change?
A 25% discount means that you pay 75% of the price.
75% = 0.75
A 7% sales tax means that you pay 107% of the price.
107% = 1.07
15 × $5 × 0.75 × 1.07 = $60.19
$100 - 60.19 = $39.81
Answer: $39.81
A couple took out a $5,000 loan from the bank. The loan had a simple interest rate of 7.5% per year. By the end of the loan, the couple had paid $2,250 in interest.
What was the length of the couple’s loan?
Answers
Answer: They couple's loan was 6 years.
Step-by-step explanation: 7.5% of 5000 is 375, 2,250 divided by 375 is 6.
#1.) 3% of $400 is what number?
#2.) 30% of 11.5 is what number?
#3.) 2% of $3,350 is what number?
#4.) 534 is what percent of 600?
#5.) 70 is what percent of 700?
show all your work!!!
Answers
Answer:
see below
Step-by-step explanation:
3% * 400 = 3/100 * 400 = 3*4 =12
30% of 11.5 = 30/100 * 11.5 = 3.45
2% of 3350 = 2/100 * 3315 = 67
x = 535/600 =0.891, so 89.1%
x = 70/700 = 0.1 so 10%

-What is the y-intercept of the line of best fit?
-What is the slope of the line of best fit for this scatter plot?
-What is the equation of the line of best fit?
Answers
Answer:
y-intercept : 8
slope: -1/2
equation: [tex]y = -\dfrac{1}{2}x + 8[/tex]
Step-by-step explanation:
The y-intercept is where the line crosses the y axis and you can see it crosses at y = 8 (when x =0)
Slope of the line can be found by the formula (y2-y1) / (x2-x1) where 9x1, y1) and (x2, y2) are two points on the line
Let's take the points (0, 8) and (10, 3) the two extreme points on the line
Slope = (3 - 8) / (10 - 0) = -5 / 10 = - 1/2
Equation of a line in slope intercept form is
y = mx + c
where m is the slope
b is the y intercept
The equation of the line is therefore
[tex]y = -\dfrac{1}{2}x + 8[/tex]
Answer:
Y-intercept = 8
Slope = -1/2t
Equation = y =-1/2x+8
Step-by-step explanation:
When x = 0, y = y-intercept.
Therefore, the y-intercept is 8.
We can find the slope using the formula y2-y1 / x2-x1 = m.
Let's use the points (0,8) and (4,6)
6-8 / 4-0 = m;
m = - 1/2.
Given that the generic formula is y=mx+b, and m-slop and b=y-intercept, we have:
y = -1/2x+8.

1. 11 + (20 - 13)
Always start with the parentheses, so first, you will subtract 20 - 13 which will give you 7, with the 7 you will add it to the 11 because that's a leftover number, so you would have to add 11 + 7 which would equal 18.
I usually remember this:
Please Excuse My Dear Aunt Sally,
It stands for
P =Parentheses
E= Exponents
M =Multiplication
D = Division
A = Addition
S = Subtraction
------
Always go in order, that's why I said "Always start with the parentheses" because it's in the first place.
-Hope this helps, good luck !
It stands for,
B-Brackets,
O-Orders (powers/indices or roots),
D-Division,
M-Multiplication,
A-Addition,
S-Subtraction.
This is the order.
But the order depends on which operation comes first. If the division part comes before multiplication, then we first divide before multiplying. If the multiplication comes in before division, then we multiply before dividing. This is same for addition and subtraction too.Here are some examples for multiplication and division.
1) 2 x 8 ÷ 4
=16 ÷ 4
= 4
2) 4 ÷ 2 x 8
= 2 x 8
= 16
Any how you should do multiplication and division before addition and subtraction according to BODMAS.
I will make 6th sum in your paper.
6) ( 2 + 3) x ( 11 - 5 )
= 5 x 6
=30
Study this example,Try to solve
[18 - 2(5 + 1)] ÷ 3 + 7
We begin with solving the innermost bracket first. Starting with 5 + 1 = 6. Thus, [18 - 2(6)] ÷ 3 + 7
Next, we work with the order, thereby multiplying 2 (6) or 2 × 6 = 12. Thus, [18 - 12] ÷ 3 + 7
There is one bracket left, [18 - 12] = 6. So, 6 ÷ 3 + 7
After B and O comes D, hence, 6 ÷ 3 = 2. So, 2 + 7

A: if 1200 are in the district, how many students will be expected to oppose
B: Based on the survey a student is more likely to be either undecided or opposed than in favor (agree or disagree) (why or why not)
Answers
Answer: The number of students expected to oppose cannot be determined from the given information. More details about the context of the survey, such as the survey questions, sample size, and response rate, may be needed to make any predictions about student attitudes.
If a survey is designed in a way that encourages students to have a neutral or negative response, or if the survey is biased in some way, it could explain why students are more likely to be undecided or opposed than in favor.
It is important to analyze survey data carefully and consider factors that may influence student responses, such as demographic characteristics, prior knowledge or experiences, and social or cultural factors.
Furthermore, it may be helpful to conduct follow-up research, such as interviews or focus groups, to gain a deeper understanding of student perspectives and attitudes.
Ultimately, any conclusions drawn from survey data should be based on sound statistical methods and rigorous analysis to ensure accuracy and reliability.

Answer:

Step-by-step explanation:
First, we have to find the area of the rectange which is 221ft² because the formula for finding the area of a rectangle is length x width. Now since we know that each square ft is equal to $11, we have to multiply 11 x 221 which gives us our answer 2431. Now we just add the dollar sign in front and it become $2431!

Answers
The number of digits is an illustration of combination, and there are 40,000 possible codes that start with a prime number that Genevieve could create
How to determine the number of digits?
The given parameters are:
Length = 5
First digit = Prime number (2, 3, 5, and 7)
This means that the first digit can be any of the 4 prime numbers, while the other four digits can be any of the 10 digits 0 - 9
So, the number of codes is
Code = 4 * 10 * 10 * 10 * 10
