Does (–3, 9) make the equation y = –3x true?

Answer: A reflection over the x axis followed by a rotation of 180 about the orgin

Step-by-step explanation:

A reflection over the x-axis followed by a rotation of 180 about the origin.

We have given that,

A reflection over the r-axis followed by a rotation of

180° about the origin.

a reflection over the r-axis followed by a translation

4 units to the left.

B a reflection over the y-axis followed by a translation

10 units down 10.

a reflection over the y-axis followed by a reflection over the axis

We have to determine the set of transformation

The straight line through all fixed points of a rotating rigid body around which all other points of the body move in circles.

Therefore A reflection over the x-axis is followed by a rotation of 180 about the origin.

Answer: All real numbers :)

Answer:

Where are the answer choice?

To have only one solution the two lines must have different slopes, then the correct option is:

y = x + 4.

We want our system to have exactly one solution, so the two lines must have different slopes.

The already graphed line s:

y = 2x + 4

Notice that the slope is 2, then we need to select the option with an slope different than 2, which is the last option:

y = x + 4

If we graph that line, the system will have only one solution.

Answer:

The bridge is 80 feet long

Step-by-step explanation:

We will use the ratio method to solve the question

∵ The engineer used the scale 3 inch = 40 feet

∴ The scale drawing is ⇒ 3 inche :  40 feet

∵ The drawing length of the bridge is 6 inches

→ By using the ratio method

→  inch :  feet

→  3      :  40

→  6      :  x

→ By using cross multiplication

∵ 3 × x = 6 × 40

∴ 3x = 240

→ Divide both sides by 3

∴ x = 80

∵ x represents the actual length of the bridge

∴ The bridge is 80 feet long

Answer:

Point A at Quadrant 2

Step-by-step explanation:

For point (-2, 4) the -2 is the x-axis and the 4 is the y-axis. All points at -2 on the x-axis are A, J, and K. All points at 4 on the y-axis are A, B, and C. Since point A is satisfies both of the places on the x-axis and the y-axis, your answer is point A.

Answer:

132 whole 1 pound packages.

Step-by-step explanation:

6 ounces times 350* equals 2100 ounces, so the summer cap needs 2100 ounces of sausage to feed all 350 children. We already know there are 16 ounces per pound. 16 x 131 equals 2096. Remember, it takes 2100 ounces to feed all 350 children. The summer camp will have to buy 132 packages to exceed 2100 without having additional whole packages.

*this number represents the amount of children

The camp needs to buy 132 packets of sausage to serve 350 students.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, A summer camp is providing breakfast for 350 children that include a 6-ounce serving of sausage per student.

So, The total amount of sausages is,

= 6×350 ounces.

= 2100 ounces.

Also given, sausages come in 1 pound pack.

Therefore, The number of packets required is,

= (2100/16).

= 131.25 but they have to buy 132 packets.

Answer:

The sum of the interior angle measures of the polygon is 540°

Step-by-step explanation:

The formula of the sum of the measures of the interior angles of a polygon is

∑m = (n - 2) × 180°, where n is the number of the sides of the polygon

In the given figure

∵ The polygon has 5 sides

∴ n = 5

→ Use the formula above to find the sum of the interior angle measures of it

∵ ∑m = (5 - 2) × 180°

∴ ∑m = 3 × 180°

∴ ∑m = 540°

∴ The sum of the interior angle measures of the polygon is 540°

B: 45+63= 9*(5+7)

Step-by-step explanation:

Answer:

b is 45+63=9(5+7)

Step-by-step explanation:

Once you know the GCF, you just need to find what the GCF (9 in this case), times what will get you 45 and 63. So we already know that 9 will be on the outside of the parentheses since it's what we're multiplying by. 9 times 5 is 45, so for the first number in the parentheses you'll put 5, and for the second, 9 times 7 is 63, so the second number in the parentheses is 7. You can check by solving it. 9(5+7). Use the distributive property and first you will do 9 times 5, which is 45, then 9 times 7 which is 63, so you'll get 45+63, which is correct.

The image coordinates are:

A'(0, 0)

B'(-8, -8)

C'(4, -8)

The graph of the image coordinates attached below.

The image triangle A'B'C' is illustrated in green color.

Step-by-step explanation:

Let the points of a triangle be

We need to determine the graph of the image of this triangle after a dilation with a scale factor of 2 centered at the origin.

A dilation by a scale factor of 2 centered at the origin means the coordinates of the image can be obtained by multiplying the original coordinates with 2.

Next, the rule of dilation by a scale factor of 2 is given by

Dilation: (x, y)  →  (2x, 2y), centered at (0, 0)

P(x, y)  → P' (2x, 2y)

A(0, 0) → A' (2(0), 2(0)) → A'(0, 0)

B(-4, -4) → B' (2(-4), 2(-4)) → B'(-8, -8)

C(2,-4) → C' (2(2), 2(-4)) → C'(4, -8)

Therefore, the image coordinates are:
