180 degrees rotation
Required
Determine the coordinate point S'
For a 180-degree rotation, the transformation rule is: (x, y) to (-x, -y)
So:
[tex]S = (2,1)[/tex] ==> [tex]S' = (-2,-1)[/tex]
Hence, the coordinate point of S' is (-2,-1)
Answer:
1,-2 did it right

Tatăl Mariei i-a oferit acesteia 2 opțiuni pentru banii de buzunar: 1/4 din €5 sau 1/2 din €5. Care opțiune ar însemna mai mulți bani?
Answer:
1/2 din 5 €
Step-by-step explanation:
Opțiunea 1
1/4 din 5 €
= 1/4 × 5 €
= 1,25 €
Opțiunea 2
1/2 din 5 €
= 1/2 × 5 €
= 2,5 €
Prin urmare, opțiunea care ar însemna mai mulți bani este 1/2 din 5 €
HELP!!! A scientist needs 10 litters of 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs
Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%
10l * 20%= x liter * 35% + 10 liter*5%
x liter *35 = 10l * 20 - 10l *5= 10l*15
x liter = 10l *15/35= 4.28 L= 4.3L
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L- 4.3L= 5.7L
Step-by-step explanation:
In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:
3(x-1) - 8 = 4(1+x) +5
Answer:
x=-20
Step-by-step explanation:
3x-11=4x+9
3x=4x+20
x+20=0
x=-20

A company that manufactures calculators has determined that for every 500 calculators they make, 12 of them are defective. If this company makes 3,000 calculators in a week, how many should they expect to be defective? A.2
B.6
C.18
B.72
E.83
Answer: The answer is B
Step-by-step explanation:
You multiply 500, 6 times to get 3,000. Then multiply 12, 6 times. So 12 x 6=72
Find the equation of the line that contains the point (-4, -4) and is perpendicular to the line 4x+5y=5
Answer:
[tex]5x-4y+4=0[/tex]
Step-by-step explanation:
Given: A point which is perpendicular to the line .
To find: The equation of the line which passes through [tex](-4, -4)[/tex] and is perpendicular to the line [tex]4x+5y=5[/tex].
Solution:
We have, [tex]4x+5y=5[/tex].
Slope of the line [tex]4x+5y=5[/tex] is [tex]-\frac{4}{5}[/tex].
The line which passes through [tex](-4, -4)[/tex] is perpendicular to the line [tex]4x+5y=5[/tex].
Now, the product of the slopes of two perpendicular lines is [tex]-1[/tex].
Therefore, [tex]m\times-\frac{4}{5}=-1[/tex]
So, its slope is [tex]\frac{5}{4}[/tex].
Now, the equation of the line which passes through [tex](-4, -4)[/tex] and slope [tex]\frac{5}{4}[/tex] is:
[tex]y-(-4)=\frac{5}{4} [x-(-4)][/tex]
[tex]\Rightarrow y+4=\frac{5}{4} (x+4)[/tex]
[tex]\Rightarrow 4(y+4)=5(x+4)[/tex]
[tex]\Rightarrow 4y+16=5x+20[/tex]
[tex]\Rightarrow 5x-4y+20-16=0[/tex]
[tex]\Rightarrow 5x-4y+4=0[/tex]
Hence, the equation of the line that contains the point [tex](-4, -4)[/tex] and is perpendicular to the line [tex]4x+5y=5[/tex] is [tex]5x-4y+4=0[/tex].

Answer:
$6
Step-by-step explanation:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
there's 10
1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15
1 + 9 = 10
10 + 10 = 20
2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15
2 + 8 = 10
20 + 10 = 30
3, 4, 5, 6, 7, 11, 12, 13, 14, 15
3 + 7 = 10
30 + 10 = 40
4, 5, 6, 11, 12, 13, 14, 15
4 + 6 = 10
40 + 10 = 50
5, 11, 12, 13, 14, 15
5 + 15 = 20
50 + 20 = 70
11, 12, 13, 14
11 + 14 = 25
70 + 25 = 95
12, 13
12 + 13 = 25
95 + 25 = 120
she would 120 nickels which is
120 x 5 = 600 cents or $6
Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x + 6". · Mr. Burrows says "Nope, wrong, those are clearly different expressions" Try substituting x=5 into both expressions. Do you get the same answer for both expressions? Show your work!
Answer:
Yes, the same answer is obtained.
Step-by-step explanation:
According to Mr. Carlevato, [tex]2(2x+3)[/tex] is equal to [tex]4x+6[/tex]. However, [tex]2(2x+3)[/tex] is not equal to [tex]4x+6[/tex] according to Mr. Burrows.
Put [tex]x=5[/tex] in [tex]2(2x+3)[/tex]
[tex]2[2(5)+3]=2(10+3)=2(13)=26[/tex]
Put [tex]x=5[/tex] in [tex]4x+6[/tex]
[tex]4x+6=4(5)+6=20+6=26[/tex]
Therefore,
[tex]2(2x+3)=4x+6[/tex]
Yes, the same answer is obtained.

The length of a rectangle is twice its width. Given the length of the diagonal is $5\sqrt{5}$, find the area of the rectangle.
Answer:
Step-by-step explanation:
Width =x
Length = 2*x = 2x
Diagonal = 5√5
Use Pythagorean theorem
Length² + Width² = diagonal²
(2x)² + x² = (5√5)²
{[tex](5\sqrt{5})^{2}=5\sqrt{5} *5\sqrt{5}=5*5*\sqrt{5*5}=25*5=75[/tex]}
4x² + x² = 75
5x² = 75
x² = 75/5
x² = 15
x = √15
Width = √15
Length = 2√15
Area of rectangle = length *width
= √15 *2√15
[tex]= 2* \sqrt{15*15}\\\\= 2*15\\= 30[/tex]
= 30 square units

hiii please help i’ll give brainliest thanks
Answer:
The answer is 5 beecause coefficients are the number when you multiply a number and a variable. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

find x...............
Answer:
x=2
Step-by-step explanation:
1. AB=AC (The triangle is isosceles. This means that at least two of its sides are equal in length. Looking at the triangle in the picture, sides AB and AC look the same, so we will assume that they are equal. Note that as you get more advanced, assuming isn't the best strategy. You should always try to look for hints if you are ever unsure. For example, if there are two angles that are the same measure in a triangle, the two sides that are only touching one of these angles are equal in length. This is called the base angles theorem converse.)
2. 9x-3=6x+3 (Rewrite sides AB and AC as the values given in the picture. This is called substitution.)
3. 9x=6x+6 (Add 3 to each side)
4. 3x=6 (Subtract 6x from each side)
5. x=2 (Divide each side by 3)
