If P=(2,-1),find the image of P under the following rotation. 180 degrees counterclockwise about the origin
Answers
9514 1404 393
Answer:
(-2, 1)
Step-by-step explanation:
Rotating a point 180° about the origin in either direction is equivalent to reflecting it across the origin. The effect is to negate both coordinates.
(x, y) ⇒ (-x, -y) . . . . . rotation 180°
(2, -1) ⇒ (-2, 1) . . . . . P' rotated 180° from P
The coordinates of the rotated point are (-2, 1).

Which expression is equivalent to 2 (a + 2 b) minus a minus 2 b? 3 a + 2 b 3 a minus 2 b a minus 2 b a + 2 b
Answers
Answer:
a + 2b
Step-by-step explanation:
Given the expression
2(a+2b) - a-2b
Open the bracket
2a+(2)2b- a-2b
2a+4b - a-2b
Collect the like terms
2a-a+4b-2b
a + 2b
Hence the equivalent expression is a + 2b

Lin’s father is paying for a $20 meal.
He has a 15%-off coupon for the meal.
After the discount, a 7% sales tax is applied.
What is the total amount Lin’s father pay for the meal?
Explain or show your reasoning.
Answers
15% of $20 is $3 so subtract that from $20 and u get $17.
Then 7% of $17 is $1.19 so subtract that from $17 and you get $15.81, which is the amount Lin’s father would pay for the meal in the end.

After 32 years from now a boy will be 5 times as old as he was 8 years back.How old is the boy now?
Answers
Answer:
18 years
Step-by-step explanation:
Transforming the question in form of equation:
Let x be the current age.
x + 32 = 5(x-8)
x + 32 = 5x - 40
5x - x = 40 + 32
4x = 72
x = 18
Answer: look at this! He’s 18
Step-by-step explanation:
equation = x+32=5(x-8)
X+32=5x-40
5x-x=32+40
4x=72
X=72/4
=18
John drove his car due east for 8 miles. He then turned south and drove 15 miles. How far was he from where he started?
Answers
Answer:
John was 17 miles away from where he started.
Step-by-step explanation:
The easiest approach to this problem is to draw it out (check the attached image). Going East and turning South is the same as drawing a line towards the right, and then down on the paper.
Using the Pythagorean Theorem, we know that the sum of the square of the legs (2 smallest sides of a right triangle) is equal to the square of the hypotenuse of that triangle. In other words, [tex]a^2 + b^2 = c^2[/tex].
So to solve this, work backwards:
[tex]8^{2}+15^{2} =c^{2}\\64 + 225 = c^{2}\\289 = c^{2}\\c = \sqrt{289}\\ c = 17[/tex]
The distance between the initial and final point will be 17 miles.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
This can be expressed as
H² = P² + B²
John drove his car due east for 8 miles.
He then turned south and drove 15 miles.
Then the distance between the initial and final point will be
H² = 8² + 15²
H² = 64 + 225
H² = 289
H = 17 miles

Monica has this recipe for fruit salad. 2 1/2 cups of pers, 2/3 cups of grapes, 1 1/4 cups of apples, and 1/2 of orange slices. How many cups for fruit is it in total?
Answers
Answer:
[tex]3\frac{11}{12}[/tex] cups
Step-by-step explanation:
[tex]2\frac{1}{2} = \frac{5}{2}[/tex] of pears
[tex]\frac{2}{3}[/tex] of grapes
[tex]\frac{1}{4}[/tex] of apples
[tex]\frac{1}{2}[/tex] of orange
when adding fractions, make sure all denominators are the same:
[tex]\frac{5}{2} = \frac{30}{12}[/tex] of pears
[tex]\frac{2}{3} = \frac{8}{12}[/tex] of grapes
[tex]\frac{1}{4} = \frac{3}{12}[/tex] of apples
[tex]\frac{1}{2} = \frac{6}{12}[/tex] of orange
add all of the fractions:
[tex]\frac{30}{12} + \frac{8}{12} + \frac{3}{12} + \frac{6}{12} = \frac{47}{12}[/tex]
convert to mixed fraction:
[tex]\frac{47}{12} = 3\frac{11}{12}[/tex]

The length of Rectangle A is 20 inches and the width is 4 inches. The length of Rectangle B is
40 inches. Find the width of Rectangle B if the rectangles are similar.
Answers
Answer:
8 inches
Step-by-step explanation:
Let w be the width of rectangle B.
Since, both rectangles are similar.
Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.
[tex] \therefore \frac{20}{40} = \frac{4}{w} \\ \\ \frac{1}{2} = \frac{4}{w} \\ \\ w = 2 \times 4 \\ \\ w = 8 \: inches[/tex]
Answer:
8"
Step-by-step explanation:
Lᵃ/Wᵃ = Lᵇ/Wᵇ
20"/4" = 40"/Wᵇ
Wᵇ = (4"×40")/20"
Wᵇ = 160" ÷ 20"
Wᵇ = 8"
