Triangle Z prime is the image of triangle Z after a series of transformations.

On a coordinate plane, triangle Z has points (0, 2), (2, 6), (4, 2). Triangle Z prime has points (negative 2, 3), (negative 1, 5), (0, 3).

Aliyah and Ivan described the sequence of transformations in different ways.

Aliyah’s Sequence
Ivan’s Sequence

1. a reflection of triangle Z across the y-axis
2. a dilation by a scale factor of One-half with the origin as the center of dilation

3. a translation 2 units up
1. a dilation of triangle Z by a scale factor of One-half with the origin as the center of dilation

2. a translation of 2 units up and 2 units to the left

Which sequence or sequences are correct and why?
Only Aliyah is correct. A dilation and translation alone could not produce triangle Z prime .
Only Ivan is correct because the dilation must be the first step in the sequence.
Both Aliyah and Ivan are correct because both chose the correct scale factor for the dilation and both describe other transformations that would produce triangle Z prime.
Neither Aliyah nor Ivan is correct because the scale factor they chose for the dilation is incorrect.

Answer: $84

Step-by-step explanation:

Price of  smoke detector in Store A = $17

Price of  smoke detector in Store B =  $24

Total detectors bought = 12

Price of 12 detectors in Store A = $17 x 12 = $204

Price of 12 detectors in Store B =  $24 x 12 = $ 288

Difference = $ 288 -$ 204 = $84

Hence, he will spend $84 less than if he purchased all the smoke detectors at Store B.

Step-by-step explanation:

Answer:

∠A = 148°

∠B = 32°

Step-by-step explanation:

We know that  ∠A and ∠B are supplementary angles, this means that:

∠A + ∠B = 180°

And we also know that:

∠A = (7x + 15)°

∠B =  (x + 13)°

Then we have a system of 3 equations.

To solve it, we can replace the second and third equations into the first one, and get:

(7x + 15)° + (x + 13)° = 180°

Now we can solve this for x, but first, let's remove the degree sign so it is easier to work:

7x + 15 + x + 13 = 180

(7 + 1)*x + 28 = 180

8*x = 180 - 28 = 152

x = 152/8 = 19

Now that we know x, we can find the values of ∠A and ∠B

∠A = (7x + 15)° = (7*19 + 15)° = 148°

∠B =  (x + 13)° = (19 + 13)° = 32°

Answer:

the slope is 4

Step-by-step explanation:

You can solve this by using [tex]\frac{y2-y1}{x2-x1}[/tex] So in this case it's

[tex]\frac{7+1}{3-1}[/tex] due to the negative, you add instead of subtract. that becomes

[tex]\frac{8}{2}[/tex] Which is 4

Example of standard notation

45,000,000 ---> 4.5000000

Follow the example using the number 45,000,000. In this case, move the decimal point until it is after the first non-zero number. If moving to the left, go one additional space so that there is a whole number on the left and a mantissa on the right.

107⁷

The number of spaces the decimal point was moved becomes the exponent. If it was moved right, the exponent is negative. If left, the exponent is positive. If the exponent is zero, scientific notation isn't needed.

45,000,000 = 4.5 x 10⁷

Answer:

B is 5 the answer your welcome

Answer:

150 (not sure)

Step-by-step explanation:

Paths that only touch 5 points unrepeatedly:

I used a tree diagram to list all the workable paths, taking cell A as an example:

2*(3x2 - 1) = 10

When you start at A you would have 3 choices, but after that only two, and since DB or BD can't happen and crossing B and D for the second step is the same, I double it.

Paths that touch 5 points and reapeat one of them:

2*(3x2x2 - 1x2) = 20

Paths that touch 5 points and repeat two of them:

2*(3x2x2x2-1x2x2) = 40

Paths that touch 5 points and repeat three of them:

2*(3x2x2x2x2-1x2x2x2) = 80

The sum of the answers in these 4 senarios is the final answer.

150

Step-by-step explanation:

first convert fraction to percentage, then into a decimal.

The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.

Answer:

The slope of the line perpendicular to the line whose equation is 2x + 2y = 28 is -x.

Step-by-step explanation:

You first isolate y, then divide 2 on both sides. This gives you the equation y = x + 14. To find a slope perpendicular to the line, simply use the negative integer of x, which is -x. The slope of the line perpendicular to the line given is -x.

Answer:

C)8

Step-by-step explanation:

x=5 ,y=6

therefore , 2×12/6

= 8

Answer:

When solving inequalities you want to first group all like terms, so you'd first add 8 to both sides, and get rid of the extra number on the left side.

7x ≤ -7

Then you'd isolate the variable, so you should divide both sides by 7.

x ≤ -1

When graphing the equation the solution set includes -1 so you would put a closed circle (filled in). The variable "x" is less than and equal to -1 so you would put the arrow facing left  <----.

Answer:

The total number of servings of chicken the food bank can provide = 70 servings

Step-by-step explanation:

The given information from the table are;

The number of chicken contained in the main course of a serving of food = 2

The mass of each chicken served by the food bank = 12.6 oz

The quantity of chicken the food bank has = 110.9 pounds (1,774.4 ounces of chicken)

Therefore we have;

The mass of chicken per serving = 2 × 12.6 = 25.2 oz/serving

The total number of servings of chicken the food bank can provide = (The quantity of chicken the food bank has)/(The mass of chicken per serving)

∴ The total number of servings of chicken the food bank can provide = (1,774.4 oz)/(25.2 oz/serving) ≈ 70.413

Given that the servings are in whole numbers, we have;

The total number of servings of chicken the food bank can provide = 70 servings, to the nearest whole number.

c. StartFraction 1 Over 15EndFraction

= 1/15

Step-by-step explanation:

If x varies directly as y

This is expressed as:

x ∝ y

Constant of variation = k

Hence,

x = ky

To find k, divide both sides by y

x/y = ky/y

k = x / y

x is 10 when y is 150

Therefore,

k = 10/150

k = 1/15

Constant of variation = 1/15
