Under b. reflected in the origin B(-4, -6) would be B'(4, 6).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Point B(-4, - 6) is given lies on the third quadrant.
Now, If we reflect along y = x it would be (- 6, - 4).
But if we reflect point B(-4, - 6) along the origin it would be B'(4, 6).

Find the length of segment QA when Q(-7,10) and A(3,4).
Answer:
The length of segment QA when Q(-7,10) and A(3,4) is √136 or 11.66 units
Step-by-step explanation:
Given points are:
Q(-7,10) and A(3,4)
Here
[tex](x_1,y_1) = (-7,10)\\(x_2,y_2) =(3,4)[/tex]
The distance between two points is the length of the segment formed by those two points. The distance between 2 points is given by:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Putting the values
[tex]d = \sqrt{(3-(-7))^2+(4-10)^2}\\d = \sqrt{(3+7)^2+(-6)^2}\\d = \sqrt{(10)^2+(-6)^2}\\d = \sqrt{100+36}\\d = \sqrt{136}\\d= 11.66\ units[/tex]
Hence,
The length of segment QA when Q(-7,10) and A(3,4) is √136 or 11.66 units

Step 2:
Total of 100 Students
Step 3:
70/100 Divide
Answer:
70%
Hope This Helps :)
Answer:
70% of the students are enrolled in health class.
Step-by-step explanation:
We are given that there are 70 students enrolled in health and that 30 are not. Therefore, we need to determine the total number of students in Oscar's grade.
[tex]70 + 30 = 100[/tex]
Oscar has 100 students in his grade. If 70 of those students are enrolled in health, we can divide those students by the total number of students and convert our fraction to a decimal and then a percentage.
[tex]\displaystyle\frac{70}{100} = \frac{7}{10} = 0.7\\\\0.7 \times 100 = 70\%[/tex]
Therefore, 70% of the students are enrolled in health class.

[tex]5x + 2y = 19[/tex]
Subtract sides 5x

[tex]2y = - 5x + 19[/tex]
Divide sides by 2
[tex] \frac{2y}{2} = \frac{ - 5x + 19}{2} \\ [/tex]
[tex]y = \frac{ - 5x}{2} + \frac{19}{2} \\ [/tex]

The solution of the equation 5x + 2y = 19 for the value of y is y = (-5 / 2)x + ( 19 / 2).
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 5x + 2y = 19. The value of y will be calculated as:-
5x + 2y = 19
2y = 19 - 5x
y = ( 19 / 2 ) - ( 5x / 2 )
Therefore, the solution of the equation 5x + 2y = 19 for the value of y is y = (-5 / 2)x + ( 19 / 2).

The percent of concentration of a certain drug in the bloodstream x hours after the drug is administered is given by K(x) 5x/x^2 + 9. a. Find the time at which the concentration is a maximum. b. Find the maximum concentration.
Given :
The percent of concentration of a certain drug in the bloodstream x hours after the drug is administered is given by [tex]K(x) = \dfrac{5x}{x^2+9}[/tex].
To Find :
Find the time at which the concentration is a maximum. b. Find the maximum concentration.
Solution :
For maximum value of x, K'(x) = 0.
[tex]K'(x) = \dfrac{5(x^2+9)- 5x(2x)}{(x^2+9)^2}=0\\\\5x^2+45-10x^2=0\\\\5x^2 = 45\\\\x = \pm 3[/tex]
Since, time cannot be negative, so ignoring x = -3 .
Putting value of x = 3, we get, K(3) = 15/( 9 + 9) = 5/6
Therefore, maximum value drug in bloodstream is 5/6 at time x = 3 units.
Hence, this is the required solution.

Answer:
answer 28ab³ I think maybe
The area of the right-angled triangle is represented as the monomial [tex]12a^3b^4[/tex].
Here,
The formula to calculate the area of a right-angled triangle is:
Area = (1/2) * base * height
In this case, the right-angled triangle has a height of [tex]6ab^3[/tex] and a base of [tex]4a^2b[/tex].
Now, let's substitute these values into the formula:
Area = [tex](1/2) * 4a^2b * 6ab^3[/tex]
Now, simplify the expression:
Area = [tex]2 * a^2b * 6ab^3[/tex]
To find the monomial representation, multiply the coefficients and add the exponents of like terms:
Area = [tex]12a^{(2+1)}b^{(1+3)[/tex]
Finally, simplify the exponents:
Area = [tex]12a^3b^4[/tex]
So, the area of the right-angled triangle is represented as the monomial [tex]12a^3b^4[/tex].

Carmen returned a bicycle to Earl's Bike Shop. The sales receipt showed a total paid price of $\$211.86$, including the $7\%$ sales tax. What was the cost of the bicycle without the sales tax?
Answer:
$198
Step-by-step explanation:
Given that:
Sales price on the sales receipt (including the sales tax) = $211.86
Sales tax = 7%
To find:
The cost of the bicycle without the sales tax = ?
Solution:
First of all, we will have to let the cost of bicycle without the sales tax.
Let the cost of bicycle without the sales tax = $[tex]x[/tex]
Cost of bicycle without the sales tax and with sales tax is given as equal to $211.86.
Writing the equation as per question statement:
[tex]x+x\times 7\%=\$211.86\\\Rightarrow \dfrac{107}{100}x=\$211.86\\\Rightarrow x=\dfrac{21186}{107}\\\Rightarrow \bold{x = \$198}[/tex]
Therefore, the cost of bicycle without the sales tax = $198

If the length of a rectangular playground is represented by the expression 2x - 3, and the width is represented by 5x + 9, what expression represents the area of the playground. Leave your answer in standard form. Show all work.
Answer:
The expression for area of rectangle in standard form is: [tex]10x^2+3x-27[/tex]
Step-by-step explanation:
The area of rectangle is given by:
[tex]Area = Length * Width[/tex]
Here, in the question, we are given length and width of the rectangle
Length = 2x-3
Width = 5x+9
The area of the rectangle will be:
[tex]Area = (2x-3)(5x+9)\\= 2x(5x+9)-3(5x+9)\\= 10x^2+18x-15x-27\\= 10x^2+3x-27[/tex]
Hence,
The expression for area of rectangle in standard form is: [tex]10x^2+3x-27[/tex]
Angle measures and segment lengths. Algebra Find the value of each variable.
Answer:
The value of x is 50
Step-by-step explanation:
A secant is a line that intersects a circle in exactly two points. When two secants intersect outside a circle then the measure of the angle formed between them is one-half the positive difference of the measures of the intercepted arcsIn the given figure
∵ Two secants intersected outside the circle
∵ The measures of the intercepted arcs are 30° and 130°
∵ x is the measure of the angle formed between them
→ By using the fact above
∴ x = [tex]\frac{1}{2}[/tex] (130 - 30)
∴ x = [tex]\frac{1}{2}[/tex] (100)
∴ x = 50
∴ The value of x is 50

Answer:
Put an open circle over the 1 to the right of 0. The arrow should point all the way to -5 or the 5 to the left of 0.
Step-by-step explanation:
In order to solve this, we know that x is less than one. That means that we need to circle to be over the 1, since it is the only known number in this inequality.
Since the phrase "less than" means that x cannot be more than 1, we know that in order to find the value of "x", then we need an amount lower than one, therefore, we move to the left.

HOW WILL YOU DEAL WITH YOUR NEGATIVE ATTITUDES? ???
Answer:
I usually try and practice changing my mindset. Just try to look at things from another perspective, and if you can't, try thinking the OPPOSITE of what you thought.
Think homework is hard? Say to yourself, "Homework is easy." and trudge on through. After some time, your mindset *will* improve, and your attitudes will change from negative to positive.
Also, try to go out more often. Doing exercise, socializing, all of which will produce serotonin and will improve your outlook on life and attitude.
