Write the equation of a line perpendicular to y=-2x+1 that passes through the point (2,3)
Answer:
y = 1/2x + 2
Step-by-step explanation:
First you have to determine the slope which is the opposite reciprocal of the slope of the line given.
So we take the slope -2 and reciprocate and by flipping the numerator and denominator which makes it -1/2.
Then we have to make it the opposite, like making a negative into a positive or a positive into a negative. So that would make it positive 1/2.
We now have the slope which is 1/2 and not we have to make sure it goes through point (2,3).
To do that, we must adjust the y-intercept until it goes through that point. We result in getting the y-intercept of 2.
The answer is y = 1/2x + 2
Answer:
y = [tex]\frac{1}{2}[/tex] x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 1 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = [tex]\frac{1}{2}[/tex] x + 2 ← equation of perpendicular line

The formula A=lw gives the
area A of a rectangle with
length 1. What is the area in
square feet of a rug with a
length of 13 feet and width of
6 feet?
Answer:
78 ft^2
Step-by-step explanation:
A = lw
l = 13 ft
w = 6 ft
A = 13ft x 6 ft
A = 78 ft^2
Multiply the length by width to find Area. The unit for Area will be feet squared because both the numbers for length and width had the same unit.

The quotient of 24 and x equals 14 minus 2 times x (into an equation don’t solve)
Answer:
24 / x = 14 - 2x
Step-by-step explanation:
Quotient means division (÷ or /)
Quotient of 24 and x = 24 ÷ x
24 ÷ x is equivalent to 24 / x
14 minus 2 times x = 14 - 2x
So, the equation is
24 / x = 14 - 2x

Carrie makes 27 liters of lemonade. 8 people share the lemonade equally. Which statement is true? a Each person will receive less than 2 liters. b Each person will receive between 2 and 3 liters. c Each person will receive between 3 and 4 liters. d Each person will receive more than 4 liters.
Answer:
The correct option is;
a. Each person will receive between 3 and 4 liters
Step-by-step explanation:
The volume of lemonade Carrie makes = 27 liters
The number of people that share the lemonade = 8
The volume of lemonade each person receives = 27/8 = 3.375liters
Each person will receive more than 3 liters but less than 4 liters of lemonade
Therefore, the correct option is each person will receive between 3 and 4 liters.
Answer:
Each person will receive between 3 and 4 liters.

3n+1=19 so i'm learning to solve 2 step equations in pre algebra but i don't really understand.
Answer:
n = 6
Step-by-step explanation:
Simplifying
3n + 1 = 19
Reorder the terms:
1 + 3n = 19
Solving
1 + 3n = 19
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + 3n = 19 + -1
Combine like terms: 1 + -1 = 0
0 + 3n = 19 + -1
3n = 19 + -1
Combine like terms: 19 + -1 = 18
3n = 18
Divide each side by '3'.
n = 6
Simplifying
n = 6
Answer:
n = 6
Step-by-step explanation:
3n + 1 = 19
Subtracting 1 from both sides:
3n + 1 - 1 = 19 - 1
3n = 18
Dividing both sides by 3:
3n/3 = 18/3
Simplifying:
18/3 = 6
n = 6

1) On a road map, the distance from Louisville to St. Louis is 12 cm. If the map has
a scale of 2 cm = 20 miles, what is the distance to St. Louis?
120 miles.
All you have to do to understand this problem is the relationship between the cm and mi.
In this case:
2cm =20mi.
The relationship is times 10, because 2 x 10=20
So multiply 12 by 10, and you will get 120mi.
Therefore, the answer is 120mi.

What is ratio ?Ratios are required form comparing two or more quantities which are of same type.
a/b can be written in ratio form a:b.
According to the given question
A candy store makes a 12-lb mixture of gummy bears, jelly beans, and gobstoppers.
The mixture calls for three times as many gummy bears as jelly beans.
∴ If the mixture has 1 lb of jelly beans then it will also hence 3 lbs of gummy bears.
By going through options we can observe option B is satisfying this condition as 6 lbs of gummy bears is 3 times 2 lbs of jelly beans and the rest are gobstoppers which is 4 pounds.
For more assurance to our given choice we can check with the price of individual contents too.
Total mixture is 24 dollars and gummy bears, jelly beans and gobstoppers costs 2 dollars, 3 dollars and 1.5 dollars respectively.
∴ 6(2) + 2(3) + 4(1.5)
= 12 + 6 + 6
= 24 dollars.

Thirteen less than twice a number is fifteen. What is the equation? What is the number?
Hi there!
Let the unknown number be c.
Twice a number means we multiply that number by 2:
2c
Now, subtract 13:
2c-13
This expression is equal to 15:
2c-13=15
As soon as I added the equal sign, and the number than the expression is equal to, the expression turned into an equation.
Now, let's solve it for c.
2c=15+13
2c=28
c=14
Hope everything is clear :-)
