We need to find the new figure which is obtained by rotating the given figure by 90-degree counterclockwise.
Explanation:
Recall that when we rotate the point (x,y) 90 degrees counterclockwise then the image of the point (x,y) can be written as follows.
[tex](x,y)^{\prime}\rightarrow(-y,x)[/tex]The image of point A(-1, -2).
[tex]A(-1,-2)\rightarrow A^{\prime}(-(-2),-1)[/tex][tex]A(-2,-2)\rightarrow A^{\prime}(2,-1)[/tex]The image of point K(-2,2)

Answers
we are asked to determine the slope of the line that passes through the points (0, 3) and (2, -1). To do that we need to use the formula for the slope of a line:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where:
[tex]\begin{gathered} (x_1,y_1)=(0,3) \\ (x_2,y_2)=(2,-1) \end{gathered}[/tex]Replacing in the formula:
[tex]m=\frac{-1-3}{2-0}[/tex]Solving the operations:
[tex]m=-\frac{4}{2}=-2[/tex]therefore, the slope is -2.
To determine the y-intercept we can use the point (0,3), since this means that when x = 0, y = 3. Since the y-intercept is the value of "y" when x = 0, this means that the y-intercept is 3.
To determine the equation of the line we need to use the general form of a line equation:
[tex]y=mx+b[/tex]Where "m" is the slope and "b" the y-intercept. Replacing the value of the slope and "b"

Plot (−134,412) on the coordinate plane.
Answers
Consider the coordinate (-1 3/4, 4 1/2).
Therefore, the x coordinate and y coordinate are - 1 3/4 and 4 1/2 respectively.
First, we must move back and forth between -1 and -2 by one and three.
In order to acquire 4 1/2, we must first get 4 above the y-axis, followed by half between 4 and 5.
The location at which the horizontal line at 4 1/2 and the vertical line at -1 3/4 would connect would be marked with a coordinate.
Or,
x = - 1 ( 3/4 ) = - 7/4 = - 1.75 and;
y = 4 1/2 = 9/2 = 4.5
Hence, ( -1 3/4, 4 1/2 ) = ( - 1.75, 4.5 ).
The shown red point on the graph is the coordinate (-1 3/4, 4 1/2).

Answers
Using the data from the question, we draw the following triangles:
The dimensions are in feet.
Now, the two triangles are proportional, so if we compute the ratio between the height and the basis of the first triangle, and then we do the same with the second, we must obtain the same number:
[tex]r=\frac{h_1}{b_1}=\frac{h_2}{b_2}[/tex]Replacing the dimensions of the triangles in the last equation, we get:
[tex]\begin{gathered} \frac{h_1}{b_1}=\frac{h_2}{b_2} \\ \frac{15}{8}=\frac{375}{b_2} \end{gathered}[/tex]From the last equation we can compute b2, the basis of the second triangle, doing that we find that:
[tex]\begin{gathered} \frac{15}{8}=\frac{375}{b_2} \\ 15\cdot b_2=375\cdot8 \\ b_2=\frac{375\cdot8}{15} \\ b_2=200 \end{gathered}[/tex]So the second triangle's base is:

Answers
Height = 1/2t + 6
To find after how many days the plant is 21 inches tall, replace height by 21:
21 = 1/2t + 6
Solve for t (days)
21-6 = 1/2t
15 = 1/2t
Multiply both sides of the equation by 2:
15(2) = 1/2t (2)

Please help me. Thank you. I’m supposed to move the coordinates on the plane.
Answers
The rectangle has upper-left coordinates (3,-3), upper-right coordinates (7,-3) and area 16 square units.
By these coordinates, we know that it's base length is 7 - 3 = 4 units.
And, since the area of a rectangle is given by it's base length times its height h, which is: 4*h = 16, which implies h = 4 units.
Therefore, the botton coordinates will be (3,-3-4) = (3,-7) and (7,-3-4) = (7,-7)

Over the last three evenings, Carmen received a total of 74 phone calls at the call center. The first evening, she received 6 fewer calls than the third evening. The second evening, she received 3 times as many calls as the third evening. How many phone calls did she receive each evening?
Answers
Let x be the amount of calls that Carmen received at the third evening.
The first evening she received 6 calls fewer than the third, so that is x-6. The second evening, she received 3 times the number of calls of the third evening. So that is 3*x. The sum of this three quantities should be 74,sinche she received 74 calls in total. So, we have the equation
[tex]x\text{ - 6 +3x+x = 74}[/tex]If we add all x values we get
[tex]5x\text{ - 6 = 74}[/tex]If we add 6 on both sides, we get
[tex]5x\text{ = 74+6 = 80}[/tex]Now, if we divide by 5 on both sides, we get
[tex]x\text{ = }\frac{80}{5}=16[/tex]So in the third evening she received 16 calls. The first evening she received 16-6 = 10 calls and the second evening she received 16*3 = 48 calls.

Answers
Step-by-step explanation:
so, we need to get the slope-intercept form
f(x) = y = ax + b
"a" is as always the slope, "b" is the y-intercept (the y-value when x = 0).
as we have the slope and a point, we can start with the point-slope form and transform it :
y - y1 = a(x - x1)
with (x1, y1) being a point on the line.
y - 7 = -9(x - 2) = -9x + 18
y = -9x + 25
therefore, the functional equation is
f(x) = -9x + 25
The length of a rectangle is three more than twice the width. Determine the dimensions that give a total area of 27ft squareda. create an equation in terms of w to model this situationb. what are the solutions to this equation c. What are the length and width of the rectangle
Answers
ok
Area = 27ft^2
length = l
width = w
Equation
l = 2w + 3
Section A
Area
A = l*w
A = (2w + 3)* w or A = 2w^2 + 3w
27 = 2w^2 + 3w
2w^2 + 3w - 27 = 0 This is the equation
Section B
2w^2 - 6w + 9w - 27 = 0
2w(w - 3) + 9(w - 3) = 0
(w - 3)(2w + 9) = 0

How to find the coefficients associated with a linear coefficient
In this problem we must determine the values of two coefficients associated with a linear combination, which is equivalent to the following system of linear equations:
a + 4 · b = 12
a - b = 2
- 3 · a + 5 · b = - 2
Since the number of equations is greater than the number of variables, there are two posibilities: (i) No solution, (ii) A solution. Now we find the solution to the system formed by the first and second equations:
a + 4 · b = 12
a - b = 2
(a, b) = (4, 2)
Now we check in the third equation:
- 3 · 4 + 5 · 2 = - 2
- 12 + 10 = - 2
- 2 = - 2 (TRUE)
The coefficients (a, b) = (4, 2) are the solutions to the system.

1. Green Forest Day Camp has 43 fewer girl campers than boy campers. There are 278 boy campers. Use rounding to estimate the total number of campers. 2. Green Forest Day Camp has 43 fewer girl campers than boy campers. There are 278 boy Campers. How many actual total campers does Green Forest Day Camp have?
Answers
Answer: 513 campers
Explanation
The total number of boys in the camp is 278
There are 43 fewer girl campers than boy
Let the total number of campers be x
Let the total number of girl campers be y
Since, there are 43 fewer girl campers than boy
Hence, the total number of girl campers is
y = Boy campers - 43
Boy campers = 278
y = 278 - 43
y = 235
Since, y is the total number of girl campers, hence, the total number of girl campers is 235
The total number of campers = number of boy campers + number of girl campers
The total number of campers = 278 + 235
The total number of campers = 513 campers
The answer is 513 camperst
At a restaurant, the bill comes to $40. You decide to leave a 15% tip. How much did you leave for the tip?
Answers
The tip of 15% is 15% of the total value of the bill, which is $40. So, we need to take 15% of 40.
Taking 15% of 40 is the same as multiplying 15% by 40. 15% can also be written as:
[tex]15\%=\frac{15\%}{100\%}=0.15[/tex]So, we can take 15% of 40 by multiplying 0.15 by 40:
[tex]0.15\cdot40=6[/tex]So, the amount left for the tip is $6.
