Answer:
g^-1(x)= 1/4x-9
1 is above 4x-9
Step-by-step explanation:
g(x)= 4x-9
and g^-1 = 1/g(x)
so:
1/gx=1/4x-9
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.

Answer:
3-(-2)=3+2 {The negative signs will become +)
and 3+2=5
so option 4 is correct
Answer:5
Step-by-step explanation:
whenever a negative is multiplied by a negative, it becomes a positive.
so: 3-(-2)—>3+2=5
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
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

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 :-)
A candy store makes a 12-lb mixture of gummy bears, jelly beans, and gobstoppers. The cost of gummy bears
is $2.00 per pound, jelly beans cost $3.00 per pound, and gobstoppers cost $1.50 per pound. The mixture calls
for three times as many gummy bears as jelly beans. The total cost of the mixture is $24.00. How much of

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.

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.

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

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.
