Determine the coordinates of A(2,3) after a reflection in the line y=2

Answer:

(0, -5/2), (-2, 0)

Step-by-step explanation:

To find the y-intercept, set x = to 0 and find y:  -4y = 10.  Thus, y = -5/2.  The y-intercept is (0, -5/2).

To find the x-intercept, set y = to 0 and fid x:   -5x = 10.    Therefore the x-intercept is -2:  (-2, 0)

Answer:

252 grams

Step-by-step explanation:

To get from 6 to 42, we need to multiply 6 by 7. This means the amount of grams of insects eaten should multiplied by 7.

36 × 7 = 252 grams

Answer:

-23

Step-by-step explanation:

We are given the functions;

h(x) = 5x - 3 and j(x) = -2x

Now, we want to find h[j(2)]

j(2) = -2(2)

j(2) = -4

Thus;

h(-4) = 5(-4) - 3

h(-4) = -20 - 3

h(-4) = - 23

Answer:

$11.33

Step-by-step explanation:

First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33

The total cost of the rake is $11.33.

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, a rake was marked up 25% from an original cost of $8.80.

25% of the original cost of $8.80 is

0.25×8.80 =$2.2

So the marked up price was 8.80+2.20

= $11

He then paid an additional 3% in sales tax, that is

11 + 0.03×11 = $11.33

Therefore, the total cost of the rake is $11.33.

Answer:

D. 2^7

Step-by-step explanation:

Answer:

2^7

Step-by-step explanation:

When we multiply the same bases with exponents like 2^3*2^4 we can add the exponents and keep the base the same

2^7 would be the answer or you can simplify further to get 128

but they said simplify so 2^7 is the answer

If they said evaluate then our answer is 128

Answer:

B: 6 units

Step-by-step explanation:

just took the test

The area of triangle GHJ is 6 square units.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

To find the area of triangle GHJ, we can use the formula:

Area = (1/2) x base x height

where the base is any one of the sides of the triangle, and the height is the perpendicular distance from that side to the opposite vertex.

We can choose any side of the triangle as the base, but it is convenient to choose the side that is horizontal or vertical to simplify the calculations.

In this case,

We can choose the base to be the side GH, which has a length of 3 units (since the x-coordinates of G and H are different).

To find the height of the triangle,

We need to draw a perpendicular line from the vertex J to the base GH, and then calculate its length.

Since the x-coordinate of J is 4 and the x-coordinates of G and H are both 1, the base GH is 3 units long.

Also,

The y-coordinate of J is 5, and the y-coordinates of G and H are both 1, so the height of the triangle is 4 units.

The area of triangle GHJ is:

Area = (1/2) x base x height

Area = (1/2) x 3 x 4

Area = 6 square units

Thus,

The area of triangle GHJ is 6 square units.

Answer:

Equation B and Equation C

Step-by-step explanation:

We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

Answer:

Answer is in attachment. I am really sorry if I'm wrong.

Step-by-step explanation:

Greatest common factor (GCF) is the highest number that is a factor of 2 numbers. Not sure if that makes sense.

For example, GCF of 8 and 4 is 4, because 4 is the highest factor that fits into both numbers. 4x2=8 and 4x1=4.

In this case, the height is 7, because that's the GCF of 21 and 70. There's no bigger common factor than that. 7x3=21 and 7x10=70

Now that we know the "height", even though there's no such thing as height when calculating the area, we know the length.

The area of something is length x width. Your assignment calls it height for some reason so we'll use height x length.

Area of the 2 shapes is already given, which is 21n for the first shape. Length of the first shape is 3n because 3nx7=21n. Recall that 7 is what we found earlier.

As we can see, the "height" of the 2nd shape is the same as the first, therefore it should also be 7.

Since we are given the area of the 2nd shape, we now know its length. Length of 2nd shape is 10, because 7x10=70.

Answer:

45/7 rounds

6 3/7 rounds

Step-by-step explanation:

Here is the full question

Nicole is playing a video game where each round lasts 7/12 ​ fraction of an hour. She has scheduled 3 3/4 fraction hours to play the game. How many rounds can Nicole play? rounds

Number of rounds she can play = total time she has scheduled / length of each round

length of each round = 7/12

total time she has scheduled = 3 3/4

3 3/4  ÷ 7/12

3 3/4 x 12/7

convert to the total time scheduled to an improper fraction

to convert to improper fraction, take the following steps :

[tex]\frac{15}{4}[/tex] × [tex]\frac{12}{7}[/tex] = [tex]\frac{45}{7}[/tex] rounds or [tex]6\frac{3}{7}[/tex] rounds

Answer:

That would be -2n - 1.

Answer:

-2n - 1

Step-by-step explanation:

You have to combine like term which would be 4n,n,and 7n.

Since n doesn't have a variable just add a one in front. So now the equation would be

1n+4n-7n That equation equals -2n

Now just add the remaining number

So that makes the answer -2n -1
