solve for A
R=x(A+B)
To solve the equation R=x(A+B) for A, divide both sides by x to get R/x = A+B. Then, subtract B from both sides to isolate A. The final equation is A = R/x - B.
Explanation:The goal is to solve for A in the equation R=x(A+B). It's a simple problem of algebraic manipulation. Here's how to do it step by step:
First, divide both sides of the equation by x to isolate the term (A+B). This gives R/x = A+B.Next, subtract B from both sides of the newly formed equation to isolate A on one side. This gives us A = R/x - B.And there you have it! The value of A in terms of R, x, and B is A = R/x - B.

Question options:
$108.60
$77.01

The total amount of his order is $157.03.
The total amount of the order is the sum of the items bought, the tax paid an the cost of shipping and handling .
Total cost of the order = cost of the items bought + tax paid + shipping and handling
Total cost of the items bought = cost of jacket + slacks + shirt
$70 + $30 + $38 = $138
Tax paid = 6% x $138 = $8.28
Shipping and handling = $10.75
Total cost = $138 + $8.28 + $10.75 = $157.03

Given y = 4x + 3, what effect does changing the equation to y = 2x + 3 have on the slope?
Changing the slope of the equation from 4 to 2 reduces the steepness of the line in the graph, with the y-intercept remaining constant at 3.
Explanation:The student asked about the effect on the slope of the linear equation when changing from y = 4x + 3 to y = 2x + 3. The slope of the first equation is 4, which can be seen from the coefficient of x, indicating a rise of 4 on the vertical axis for every increase of 1 on the horizontal axis. When the equation changes to y = 2x + 3, the slope is reduced to 2, which means there is a rise of 2 on the vertical axis for every increase of 1 on the horizontal axis. This change in the slope would cause the line to rotate clockwise when graphed on a coordinate plane. The y-intercept remains the same at 3 since it is unchanged in both equations. Therefore, changing the equation has the effect of decreasing the steepness of the line, but the location where the line crosses the y-axis does not change.

What is the axis of symmetry for f(x)=2x2+8x+8
Answer: The axis of symmetry for the function f(x) is x = -2.
Step-by-step explanation: We are given to find the axis of symmetry for the following function :
[tex]f(x)=2x^2+8x+8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
for a function g(x) with the form [tex]g(x)=a(x-h)^2+k,[/tex] the axis of symmetry is given by the following equation :
[tex]x-h=0~~~~\Rightarrow x=h.[/tex]
Now, from equation (i), we have
[tex]f(x)=2x^2+8x+8\\\\\Rightarrow f(x)=2(x^2+4x+4)\\\\\Rightarrow f(x)=2(x+2)^2+0.[/tex]
Therefore, the required axis of symmetry is given by
[tex]x+2=0\\\\\Rightarrow x=-2.[/tex]
Thus, the axis of symmetry for the function f(x) is x = -2.
A pet store has 12 puppies, including 3 poodles, 5 terriers, and 4 retrievers. if rebecka and aaron, in that order, each select one puppy at random without replacement, find the probability that aaron selects a retriever, given that rebecka selects a poodle.
The probability that Aaron will select a retriever given that Rebecka has selected a poodle is 4/11.
To calculate the probability that Aaron selects a retriever given that Rebecka selects a poodle, we will use the concept of conditional probability. The total number of puppies is 12, and the number of poodle puppies is 3.
When Rebecka selects a poodle, one puppy is removed from the total, leaving 11 puppies, including the same 4 retrievers (since she did not pick a retriever).
The probability that Aaron picks a retriever given Rebecka has picked a poodle is:
P(Aaron picks a retriever | Rebecka picks a poodle) = P(Rebecka picks a poodle and Aaron picks a retriever) / P(Rebecka picks a poodle)
Since Rebecka has already picked a poodle, we focus only on the event where Aaron picks a retriever. So the probability becomes:
P(Aaron picks a retriever | Rebecka picks a poodle) = Number of retrievers left / Total number of puppies left
= 4 retrievers / 11 total puppies
= 4/11

A) reflect triangle 1 across the y-axis
B) reflect triangle 2 across the y-axis
C) rotate triangle 2 counter-clockwise 90° about the origin
D) reflect triangle 2 across the y axis and rotate 90° about the origin at
Answer:
The correct option is C.
Step-by-step explanation:
From the given graph it is noticed that the vertices of triangle 1 are P'(-2,2), Q'(-4,4) and R'(-2,4). The vertices of triangle 2 are P(2,2), Q(4,4) and R(4,2).
If a figure rotated counter-clockwise 90° about the origin, then
[tex](x,y)\rightarrow (-y,x)[/tex]
If we rotate triangle 2 counter-clockwise 90° about the origin, then[
[tex]P(2,2)\rightarrow P'(-2,2)[/tex]
[tex]Q(4,4)\rightarrow Q'(-4,4)[/tex]
[tex]R(4,2)\rightarrow R'(-2,4)[/tex]
If we rotate triangle 2 counterclockwise, then we get the triangle 1.
Therefore the correct option is C.
Which correctly describes a cross section of the right rectangular prism if the base is a rectangle measuring 15 inches by 8 inches? Check all that apply.
-
A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.
A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.
Answer:
A cross-section parallel to the base is a rectangle measuring 15 inches by 8 inches.
A cross-section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross-section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.
the cross sections that are parallel and perpendicular will have the same measurements as the non-intersected sides. the last one will be a diagonal so the intersected edge is 6 and it creates a right triangle so it must be larger than 15 inches.

C. all real numbers except n(pi)/2, where n is any integer
D. all real numbers except n(pi), where n is any integer
Answer:
all real numbers
Step-by-step explanation:
Given : y = cot(x)
To Find: Range.
Solution:
Refer the attached graph.
The domain of the function [tex]y=cot(x)=\frac{cos(x)}{sin(x)}[/tex] is all real numbers except the values where sin(x) is equal to 0 , that is, the values πn for all integers n .
The range of the function is all real numbers.
Referring the graph we can say that the range of the given function y = cot(x) is all real numbers .
Hence Option A is correct.

The product of a number (n) and 12 is 64. Which equation shows this relationship
12+n=64
64n=12
12n=64
64-n=12
The equation that shows the relationship between the number (n) and 12 being multiplied to equal 64 is 12n = 64, the correct option is C.
In this equation, the variable n represents the number we are trying to find. The equation states that when we multiply 12 and n together, the result is 64.
To solve this equation and find the value of n, we divide both sides of the equation by 12:
(12n)/12 = 64/12
n = 64/12
Which can be further simplified to:
n = 16/3
Therefore, the equation that represents the relationship between the number (n) and 12 being multiplied to equal 64 is 12n = 64.
