The inverse function of 3x - 4 is (x+4)/3. so a
Step-by-step explanation:
f(x) = 3x - 4
y = 3x - 4 replace f(x) with y
x = 3y - 4 replace x with y and y with x.
3y = x + 4 solve for y
y = (x+4)/3 replace y with f-1(x)
f-1(x) = (x+4)/3

Step-by-step explanation:
Dear friend,
I hope you are well. The rest of this letter will explain your math problem.
As you can see from the diagram below, there are 3 individual shapes that make up the figure. Let us find the area of each shape individually.
The formula to find the area of a circle is π[tex]r^{2}[/tex]. However, we are finding a semicircle so we must solve for half of a circle. The formula becomes [tex]\frac{1}{2} \\[/tex]π[tex]r^{2}[/tex]. The [tex]r[/tex] in the formula is the radius. It is given the diameter (which is double the radius) is six. Therefore, the radius is 3 in. If plug in the values we get [tex]\frac{1}{2}(3^{2})[/tex]π which is 4.5π I am not sure if you want the answer in terms of π or just the estimated value. The estimated value (using 3.14 instead of π) would be 14.13.
Now we shall find the area of the rectangle. This is a 6x10 inch rectangle. The answer is 60. You probably know how to solve multiplication. 6 can be seen as 6.0. Multiplying by 10 moves the decimal point one number to the right so it becomes 60.0: 60.
The length of the base of the triangle can be found even though the diagram does not directly give us the base length. the length of the base of the rectangle and triangle combined is 14 inches. We know that the rectangle has a base length of 10 because it is given. Therefore we must find the remaining length which is 4 because 14-10=4. The formula for finding the area of a triangle is [tex]\frac{(base)(height)}{2}[/tex] we know that the base is 4 and the height is 6 so we plug in the numbers and simplify to get 12.
We must add each of the areas to find the area of the whole figure. The Semi-circle is 4.5π(14.13) and the rectangle is 60 and the triangle is 4. The answer is 64 + 4.5π or 78.13

^The formula for the circumference of a circle is C=2∏r, in which r=radius. To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.

Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answers
Answer: [tex]13x+26 \ge 65[/tex]
If you solve for x, you get [tex]x \ge 3[/tex] which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as [tex]13x+26 \ge 65[/tex] which sets up the inequality.
----------------------------
Let's solve for x
[tex]13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\[/tex]
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).

65= 26+13x

hope it helps.
sorry if wrong.
The first one is he started with 10 5/8 cups
9•9/8 cups = 81/8 cups into the bowls + 4/8 cup left over
For number 2, convert to common denominator fractions. (The first is 40 for the denominator, the second is 24)
So -10/40(128/40+5/40)
-10/40(133/40)
-1330/40
-33 1/4
The second part of #2
-8/24(12/24 + 3/24)
-8/24(15/24)
-120/24
