Answer:
The correct option is;
(-2, 213) and (2, -213)
Step-by-step explanation:
The reflection of a point across the x-axis is given as follows;
The coordinates of the point of the pre-image = (x, y)
The coordinates of the point of the image after reflection = (x, -y)
The reflection of a point across the y-axis is given as follows;
The coordinates of the point of the pre-image = (x, y)
The coordinates of the point of the image after reflection = (-x, y)
Therefore, from the given points, The reflection across the y-axis of the point (-2, 213) is (2, 213) and the reflection across the x-axis of the point (2, 213) is (2, -213)

What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units? (5 points)
Square root of 8 units
4 units
Square root of 32 units
8 units
Answer:
sq rt of 32 units
Step-by-step explanation:
use the pythagorean theorem:
4^2 + 4^2 = c^2
16 + 16 = c^2
32 = c^2
sq rt of 32 = c
The length of the hypotenuse of a right triangle is 4√2.
What is Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given:
P= 4 units, B= 4 units
Now, using Pythagoras theorem
H² = P² + B²
H² = 4² + 4²
H²= 16+ 16
H² =32
H= √32
H= 4√2
Hence, the Hypotenuse is 4√2.

A cellphone store has 120 cell phones in stock. Of these, 45 have keyboards. The manager of the store wants to add more cell phones with keyboards so that 40% of the stock has keyboards.
Answer:
5
Step-by-step explanation:
Let x be the number of cell phones with keyboards needed.
40% = [tex]\frac{40}{100}[/tex]
[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]
x+45 = 40 -----1
x+120 = 100 -----2
You would want to make the total of 1 the same as 2.
1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3
Now 2 and 3 are equal.
x+120 = 2.5x+112.5
Isolate the x and numbers.
120-112.5 = 2.5x-x
Simplify.
1.5x = 7.5
x = [tex]\frac{1}{1.5}[/tex] × 7.5
x = 5
The manager of the store needs to add 5 more cell phones with keyboards.

Larry says 5 × 900 is less than 5 × 9,000. Doni says 5 × 900 is greater than 5 × 9,000. Which statements about the two products are correct? Choose all that apply.
Answer:
Larry's statement is correct
Step-by-step explanation:
Larry says 5 × 900 is less than 5 × 9,000.
Doni says 5 × 900 is greater than 5 × 9,000.
5 × 900 = 4500
5 × 9000 = 45,000
45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.
Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)

Answer:
j=3+25, here's the equation
Step-by-step explanation:
J=28
Answer:
j = 28
Step-by-step explanation:
Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

Gabriel invested $77,000 in an account paying an interest rate of 3 1/2% compounded monthly. Isabella invested $77,000 in an account paying an interest rate of 4 1/8% compounded quarterly. After 6 years, how much more money would Isabella have in her account than Gabriel, to the nearest dollar?
WE know, compound interest is given by :
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Here, P is principle amount.
r is annual interest rate.
n, number of times that interest is compounded per unit t .
t, time the money is invested or borrowed for.
To Find :
How much more money would Isabella have in her account than Gabriel, to the nearest dollar.
Solution :
[tex]D = P(1 + \frac{r_1}{n})^{nt}- P(1 + \frac{r_2}{n})^{nt}\\\\D = 77000\times ( 1 + \dfrac{33}{8\times 12})^{12\times 6}-77000\times ( 1 + \dfrac{7}{2\times 12})^{12\times 6}\\\\D = \$(1.257\times 10^{14})[/tex]
Hence, this is the required solution.

express 20cm as a percentage of 3m.
give your answer as a mixed number
Answer:
[tex]6\frac{2}{3}[/tex] %
Step-by-step explanation:
First, convert 3 meters into centimeters.
1m = 100cm
3m = 100 × 3 = 300cm
Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.
[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex] ⇒ Simplify your fraction to its simplest terms.
Next, multiply your simplified fraction by 100 to get your percentage.
[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] % ⇒ Simplify your percentage to its simplest terms.

What is the image of the point (-7, -3) after a rotation of 90° counterclockwise
about the origin?
The new point after rotation of point (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).
What are coordinates?
A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given,
Point A = (-7, -3)
Let's say after rotation this point moves to a new coordinate (x, y) which is point B
Let's say the origin is O
Slope of line segment AO = (-3-0)/(-7-0) = 3/7
Slope of line segment BO = (y - 0)/(x - 0) = y/x
Now,
Since both lines are perpendicular to each other so
Slope AO × Slope BO = -1
3/7 × y/x = -1 ⇒ 3y = -7x
Now if we observe the result then it will be clear that if we put x = 3 than y = -7 will be the new coordinate.
Hence, The new point after rotation of point (-7, -3) counterclockwise by 90 degrees will be ( 3, -7).

The store sells gasoline for .25 per gallon below it's regular cost per gallon .Suppose the store sells 5,750 gallons that day .What is the stores profit or loss in comparison to the amount the store would had made without the special
Given :
The store sells gasoline for .25 per gallon below it's regular cost per gallon.
Suppose the store sells 5,750 gallons that day.
To Find :
the stores profit or loss in comparison to the amount the store would had made without the special offer.
Solution :
Since, store is selling gasoline for lower amount than regular so they will be in loss.
Loss =$ 0.25 × 5750
Loss = $1437.5
Therefore, loss of store in comparison to the amount the store would had made without the special offer is $1437.5 .
Hence, this is the required solution.
4(2x - 1) = 3x + 6 Solve for x. Show steps with sentences supporting each step.
Answer:
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
Simplify
8x - 4 = 3x + 6
Subtract 3x from both sides
8x - 3x - 4 = 3x - 3x + 6
5x - 4 = 6
Add 4 to both sides
5x - 4 + 4 = 6 + 4
5x = 10
Divide both sides by 5
5x/5 = 10/5
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
8x-4=3x+6
8x-3x=6+4
5x=10
x=10/5=2
