The slope - intercept form of the equations of each of the given lines is:
y = x + 3y = - 2x - 6 y = - 4x - 7How to find the slope - intercept form?The slope - intercept form is:
y = mx + b
Where
m = slope
b = y - intercept
Basically, given the equations of each line, you are to move y such that it goes to the left of the equation and remains there alone, while the other figures stay on the right side.
Equation 1:
x − y = −3
x + 3 = y
y = x + 3
Equation 2:
2x + y = −6
y = - 6 - 2 x
y = - 2x - 6
Equation 3 :
4x + y = −7
y = - 4x - 7

The difference between double a number and 4 is 16
Answer:
2x - 4 = 16
Step-by-step explanation:
'the difference' shows that its subtraction so u have to put a - in the equation
'double' means 2 and since you dont know the value of 'a number' you replace it with a variable like x. combine them and you get 2x
so far it should look like 2x -
4 is equal to 4 so just put a 4 in front of the subtraction sign
it'll look like 2x - 4 now
'is 16' basically means is equal to 16 so now ur equation should look like:
2x - 4 = 16
if you wanted to solve that u could add 4 to both sides then divide both sides by 2 and get x = 10
Answer:
x = 10
Step-by-step explanation:
2x - 4 = 16
2x = 20
x = 10

5:3
Hope that helps! (If you're up for it, can you give me a brainliest? Thanks)
The ratio is 5:3
What is ratio?A ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six.
Given:
Total participants= 224
nonresidents =84
So, residents= 224-84 = 140
Now, ratio of residents to nonresidents
=140/84
=70/42

For each statement, write what would be assumed and what would be proven in a proof by contrapositive of the statement. Then write what would be assumed and what would be proven in a proof by contradiction of the statement.
a. If x and y are a pair of consecutive integers, then x and y have opposite parity.
b. For all integers n, if n² is odd, then n is also odd.
Answer:
a.)
Statement - If x and y are a pair of consecutive integers, then x and y have opposite parity.
Contra-positive statement - If x and y have same parity, then x and y can not be a pair of consecutive integers.
Assumed - x and y have same parity
To prove - x and y can not be a pair of consecutive integers.
Contradiction statement - If x and y are a pair of consecutive integers and they have same parity then then it is not possible.
Assumed - x and y are a pair of consecutive integers and they have same parity
To prove - It is not possible
Proof - Let x and y are even numbers
⇒x = 2a , y = 2b
then , y - x = 2b - 2a = 2(b - a) is alteast 0 if x ≠y
Contradiction.
b.)
Statement - For all integers n, if n² is odd, then n is also odd.
Contrapositive statement - If n is even , then n² is even
assumed - n is even
To prove - n² is even
Contradiction - If n² is odd and n is even then it is not possible
Assumed - n² is odd and n is even
To prove - Our assumption is not true
Proof - As n is even
⇒n = 2a
⇒n² = (2a)² = 4a²
⇒n² is even
Contradiction.

What is Comparison factor?Factor comparison is a systematic and scientific way of job appraisal that assesses jobs based on a number of characteristics rather than the job as a whole. The goal of factor comparison is to assign monetary worth to the various components of each employment role.
First, Tess and Alice swam laps for the same amount of time, but Tess finished more laps.
Second, they are swimming the same number of laps at a swim meet.
As, Tess finished more laps then Alice so he is always ahead of Alice.
In second time again Tess will finish more laps comparison to Alice.

Element X is a radioactive isotope such that every 66 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 240 grams, how much of the element would remain after 29 years, to the nearest whole number?
Answer:
177 grams
Step-by-step explanation:
Answer:
53grams... Approximated
Step-by-step explanation:
In 66 years = 240/2 = 120 grams
In 1 year = 120/66 gram
In 29 years = 120/66 × 29 = 52.73grams
Are 2.r = 4 and 4x + 5 = 13 equivalent?
Answer:
Yes, they are equivalent.
Step-by-step explanation:
2r = 4, r = 2. We get this because 4/2 = 2.
4x+5 = 13. Subtract 5 from both sides and we'll get 4x=8. Now divide 8/4 = 2.
So we get 2 = 2, which means that the expressions are equivalent.

Complete question :
When testing gas pumps for accuracy, fuel-quality enforcement specialists tested pumps and found that 1294 of them were not pumping accurately (within 3.3 oz when 5 gal is pumped), and 5705 pumps were accurate. Use a 0.01 significance level to test the claim of an industry representative that less than 20% of the pumps are inaccurate. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.
Answer:
H0: p=0.2
H1: p<0.2 ;
- 3.16 ;
0.0008 ;
p value is < α ; We reject the Null.
Therefore we conclude that there is sufficient evidence to support the claim that less than 20% of the pumps are inaccurate
Step-by-step explanation:
The null hypothesis ; H0 : p = 20%
Alternative ; H1 : p < 20%
Sample size, n = 1294 + 5705 = 6999
p = inaccurate / total
p = 1294 / 6999 = 0.1849
The test statistic (Z) :
(P - P0) ÷ sqrt((P0(1 - P0)) /n)
P0 = 0.2
(0.1849 - 0.2) ÷ sqrt((0.2 * 0.8)/6999))
−0.0151 ÷ 0.0047812
= - 3.1582029
= - 3.16
Pvalue : using the Pvalue from Zstatistic calculator at α = 0.01
P value = 0.000789
P value = 0.0008 (4 decimal places).
Since p value is < α ; We reject the Null.
Therefore we conclude that there is sufficient evidence to support the claim that less than 20% of the pumps are inaccurate

Mrs. Wilson bought 2 boxes of candy for the party. After filling the pinata and the candy dish, she had ⅚ of a box left. If she split the remaining candy into 10 goodie bags, how much of a box of candy did she put in each bag?
Answer:
Mrs Wilson put 1/12 of the box of candy in each goodie bag
Step-by-step explanation:
5/6 is kinda hard to divide into 10 pieces left like it is, so we turn 5/6 into 10/12 (they're both the same)
Then from here, it's easy
10/12 and 10 goodie bags
So 1/12 goes into each one

A, B, C and D and ADC = 120
Find the value of x.
Answer:
30 degrees
Step-by-step explanation:
The computation of the value of x is given below:
Given that
ADC = 120 degrees
So ABC = 60 degrees
As the sum of the opposite angles are 180 degrees
And ACB = 90 degrees
Now in Triangle ADC
Angle ACB + Angle ABC + x = 180 degrees
90 + 60 + x = 180
x = 30 degrees
