Answer:
y=2x
Step-by-step explanation:
From (0,0) to (3,6), it is 3 units to the left and 6 units left, divide that so you can have 1 unit to the left and 2 units up. Therefore, the answer is y = 2x.
Which expression is equal to 632?
Answer:
2*316
Step-by-step explanation:
Solve the system of linear equations by substitution. Check your solution.
The solution to the system of linear equations is x = -6 and y = 2.
Solving the system of linear equations by substitution:
The system of linear equations is:
2x + 4y = -4
x - 3y = -12
We can solve this system by substitution. First, we can solve the second equation for x:
x = 3y - 12
Substituting this expression for x into the first equation, we get:
2(3y - 12) + 4y = -4
Simplifying the right side of the equation, we get:
6y - 24 + 4y = -4
Combining like terms, we get:
10y - 24 = -4
Adding 24 to both sides of the equation, we get:
10y = 20
Dividing both sides of the equation by 10, we get:
y = 2
Now that we know the value of y, we can substitute it into the second equation to solve for x:
x - 3(2) = -12
Simplifying the right side of the equation, we get:
x - 6 = -12
Adding 6 to both sides of the equation, we get:
x = -6
Therefore, the solution to the system of linear equations is x = -6 and y = 2.

Answer: x=5, y=(5[tex]\sqrt{3}[/tex])/2
Step-by-step explanation:
Using the 30-60-90 triangle rule, we know that the sides follow 1-([tex]\sqrt{3}[/tex]/2)-2. The ratio between the side and the rule is 5/2, meaning that we know that y=(5[tex]\sqrt{3}[/tex])/2 and x=5.
Five cupcakes and two cookies cost $19.75. Two cupcakes and four cookies cost $ 17.50.
How much does a cupcake cost?
How much does a cookie cost?
Cupcake: $
Cookie: $
Answer:
Step-by-step explanation:
Let x and y represent the cost of a cupcake and cookie respectively.
Given that;
Five cupcakes and two cookies cost $19.75.
[tex]5x+2y=19.75 ---------- 1[/tex]
Two cupcakes and four cookies cost $17.50.
[tex]2x+4y=17.50 --------------2[/tex]
Let's solve the simultaneous equation by elimination;
Multiply equation 1 by 2;
[tex]10x+4y=39.50-------3\\[/tex]
Subtract equation 2 from equation 3;
[tex]10x-2x+4y-4y=39.50-8x=22[/tex]
[tex]8x=22[/tex]
divide both sides by 8
[tex]\frac{8x}{8} =\frac{22}{8} \\x=2.75[/tex]
Since we have the value of x, let substitute into equation 1 to get y;
[tex]5x+2y=19.75\\5(2.75)+2y=19.75\\13.75+2y=19.75\\2y=19.75-13.75\\2y=6\\y=\frac{6}{2} \\y=3.00[/tex]
therefore , the cost of cupcakes and cookies are;
[tex]cupcakes= 2.75\\cookies= 3.00[/tex]

Suppose that in a country of 72 million people, about 3600 die from drowning each year. What is the percent chance that a person will drown in a given year?
Answer:
Percent of people die for drowning = 0.005%
Step-by-step explanation:
Given:
Total population = 72,000,000
Number of people die for drowning = 3,600
Find:
Percent of people die for drowning
Computation:
Percent of people die for drowning = [Number of people die for drowning/Total population]100
Percent of people die for drowning = [3,600 / 72,000,000]100
Percent of people die for drowning = 0.005%

Answer:
2. -2/5
Step-by-step explanation:
y = mx + b
m represents the slope and in this case, y = -2/5x + 3, -2/5 is in place instead of m so therefore -2/5 is the slope

a retired statistician was interested in determining the average cost of a 200000 term life insurance policy for a he randomly sampled 65 subjects what value of alpha was used to create this confidence interval
Answer:
The correct option is the second option
Step-by-step explanation:
From the question we are told that
The average cost is [tex]\mu = \$ 200 000.00[/tex]
The sample size is n = 65
The upper limit of the 95% confidence interval is $1050.00
The lower limit of the 95% confidence interval is $850.00
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]

Answer:
49, 96, 400
Step-by-step explanation:
multiplying first and second numbers
The required product that belongs to the last column is given as 49, 69, 400. Option C is correct.
Given that,
A table has shown we have to determine the last column of the table.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
As mentioned in the question the element that lies in the third column is the product of the elements lying in the respective rows.
So,
1 × 49 = 49
2 × 48 = 96
10 × 40 = 400
Thus, the required product that belongs to the last column is given as 49, 69, and 400. Option C is correct.

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Ken ran 2 1/6 miles in 20.8 minutes. The amount of time taken by Ken to cover one mile will be calculated as below:-
2 ( 1/6) miles = 20.8 minute
13 / 6 miles = 20.8 minutes
1 miles = ( 6 / 13 ) x 20.8
1 mile = 9.6 minutes
Therefore, the amount of time taken by Ken to cover 1 mile will be 9.6 minutes.

Could I please get help with this, I’m very confused and don’t know how to do this. Please and thank you
Answer:
(See bolded numbers)
Factoring -1 out of negative numbers:
11) (-6) • (3)= (-1 • 6) • 3= -1 • 6 • 3= -18
-6 is the negative number here and factoring out -1 from -6 will give us -1(6). In the second last step, multiply 6 and 3 together then multiply the product by -1.
-1(6 ×3)= -1(18)= -18
12) (-4) • (-8)= (-1 • 4) • (-1 • 8)= 1 • 4 • 8= 32
Multiplying 2 negative numbers will give us a positive number. The 3rd step is 1 as (-1)(-1)= 1.
13) (-9) • (-5)= (-1 • 9) • (-1 • 5)= 1 • 9 • 5= 45
14) (2) • (-8)= 2 • (-1 • 8)= -1 • 2 • 8= -16
Negative numbers are numbers with a negative sign and are numbers less than zero. Factoring -1 out of negative numbers will leave us with the positive number.
