what is the perimeter of PQR with vertices P(-2, 9), Q(7, -3) R(-2, -3) in the coordinate plane?
Answer:
[tex]p (perimeter) = 36[/tex]
Answer:
36.
Step-by-step explanation:
The perimeter = PQ + QR + RP
= √[(-2 -7 )^2 + (9- (-3))^2)] + √[(7 - (-2))^2 + (-3 - (-3)^2)] + √((-2 -(-2)^2+(-3-9)^2)]
= √(81+144) + √81 + √144
= √225 + √81 + √144
= 15 + 9 + 12
= 36
Josef has $300 to spend. Which inequality could help him find the maximum number of gifts, x, he could buy if he needs $215 to fix his car and then wants to spend $15 on each gift?
Answer:
x = (300 - 215)/15
Step-by-step explanation:
x, the amount of gifts, is equal to the amount of money left over after he fixes his car, divided by the amount he's willing to spend on each gift.
josef could buy a maximum of 5 gifts! the answer is 5.6 but he can't buy half a gift, nor can he afford 6, so we round down to get 5 gifts :)

Find all of the points of the form (x, −x) which are 7 units from the origin.
(x, y) =
(smaller x-value)
(x, y) =
(larger x-value)
Answer:
(-7, 0) and (7, 0)Step-by-step explanation:
All the points that are 7 units from the origin are on the circle:
x² + y² = 7²The maximum and minimum values of x obtained when y = 0:
x² = 7² √x² = √7²x = ± 7So
min x = -7 and max x = 7The points are:
(-7, 0) and (7, 0)The equation will be
[tex]\\ \sf\longmapsto \sqrt{x^2+y^2}=7[/tex]
[tex]\\ \sf\longmapsto x^2+y^2=7[/tex]

Step-by-step explanation:
use coordinate notation to write the rule that maps each preimage to its image. Then confirm that the transformation is not a rigid motion.Number 8
In geometry, transformation involves changing the position and/or size of a shape.
The coordinate notations are:
[tex](x,y) \to (\frac{1}{2}x,\frac{1}{2}y)[/tex]. [tex](x,y) \to (2x,y)[/tex].Both transformations are not rigid
[tex]7.\ \triangle ABC \to \triangle A'B'C'[/tex]
Using coordinates A and A', as a reference;
We have:
[tex]A = (6,6)[/tex]
[tex]A' = (3,3)[/tex]
Divide A' by A to get the scale ratio (k)
[tex]k = \frac{A'}{A}[/tex]
[tex]k = \frac{(3,3)}{(6,6)}[/tex]
Factorize
[tex]k = \frac{(3,3)}{2 \times (3,3)}[/tex]
[tex]k = \frac{1}{2}[/tex]
Hence, the coordinate notation is:
[tex](x,y) \to (\frac{1}{2}x,\frac{1}{2}y)[/tex]
Calculate distance AB and A'B' using:
[tex]d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2}[/tex]
So, we have:
[tex]AB = \sqrt{(6 - 4)^2 +(6 - -2)^2} = \sqrt{68}[/tex]
[tex]A'B' = \sqrt{(3 - 2)^2 +(3 - -1)^2} = \sqrt{17}[/tex]
Because
[tex]AB \ne A'B'[/tex]
We've confirmed that the transformation is not rigid
[tex]8.\ \triangle FGH \to \triangle F'G'H'[/tex]
Using coordinates F and F';
We have:
[tex]F = (-1,1)[/tex]
[tex]F' = (-2,1)[/tex]
Divide the x-coordinate of F' by F to get the scale ratio (k) because the y-coordinates of the pre-image and the image are the same
[tex]k = \frac{F'}{F}[/tex]
[tex]k = \frac{-2}{-1}[/tex]
[tex]k = 2[/tex]
Hence, the coordinate notation is:
[tex](x,y) \to (2x,y)[/tex]
Calculate distance FG and F'G' using:
[tex]d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2}[/tex]
So, we have:
[tex]FG = \sqrt{(-1 - 1)^2 +(1 - -1)^2} = \sqrt{8}[/tex]
[tex]F'G' = \sqrt{(-2 - 2)^2 +(1 - -1)^2} = \sqrt{20}[/tex]
Because
[tex]FG \ne F'G'[/tex]
We've confirmed that the transformation is not rigid

Please answer this question with equation will give 20 points and mark brainliest
Hello there!
Given the equation below:
[tex] \displaystyle \large{ \frac{3x + 3}{2} = 9}[/tex]
Our first step is to get rid of the denominator by multiplying the whole equation by 2.
[tex] \displaystyle \large{ \frac{3x + 3}{2} \cdot 2 = 9 \cdot 2} \\ \displaystyle \large{ 3x + 3 = 18}[/tex]
Isolate x-term - first, we subtract 3 both sides.
[tex] \displaystyle \large{3x + 3 - 3 = 18 - 3} \\ \displaystyle \large{3x= 15} \\ [/tex]
Divide both sides by 3 to leave only x-term.
[tex] \displaystyle \large{ \frac{3x}{3} = \frac{15}{3} } \\ \: \displaystyle \large{x = 5}[/tex]
Therefore, the value of x is 5.
Checking Answer
Optional Step:
First, we substitute x-value that we got in the equation.
[tex] \displaystyle \large{ \frac{3x + 3}{2} = 9} \\ \displaystyle \large{ \frac{3(5)+ 3}{2} = 9}[/tex]
Evaluate the expression.
[tex] \displaystyle \large{ \frac{15 + 3}{2} = 9} \\ \displaystyle \large{ \frac{18}{2} = 9} \\ \displaystyle \large{ 9 = 9}[/tex]
Since both sides are equal. The equation is true!
Answer
Hence, x = 5.

Hi there!
Given;
f(x) = 5x-1
Now; Simply keep the value of x in the given function.
f(1) = 5*1-11
= -6
Again;
f(3) = 5*3-11
= 15-11
= 4
Therefore, f(1) = -6 and f(3) = 4.

Find h.
10 in.
h
h = [?] in.
4 in.
Answer:
h = sqrt(96)
Step-by-step explanation:
We can use the pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
2^2 + h^2 = 10^2
4 + h^2 = 100
h^2 = 100-4
h^2 = 96
Taking the square root of each side
h = sqrt(96)
Jacob took a total of 4 quizzes over the course of 3 weeks.
How many weeks of school will Jacob have to attend this quarter before he will have taken 16 quizzes?
Answer:
The answer would be a total of 12 weeks .
Step-by-step explanation:
Because the first four test were in a total of three weeks
so in order to find out how many weeks for 16 quizzes just multiply
4 quizzes -3 weeks
8 quizzes -6 weeks
12 quizzes - 9 weeks
16 quizzes - 12 weeks
SO just multiply 4 by 4 and multiply 4 by 3
