Which of these can be the graph of the equation

Answer:

1. W'(-4,2), X'(-1,2), Y' (-1,4), Z' (-4,4).

2. W"(4,-2), X"(1,-2), Y"(1,-4), Z"(4,-4)

RULE:

- If reflected an image over x-axis:

x stay the same, y change.

Ex: A(1,2)>>>x-axis= A'(1,-2)

- If reflected an image over y-axis:

x change, y stay the same.

Ex: B(3,4)>>>y-axis= B'(-3,4)

Answer:

-8 is less than k is less than -2

Step-by-step explanation:

I think we are trying to find k

-50 is less than 7k+6 is less than -8

-6                           -6                     -6

-56 is less than 7k is less than -14

-56/7 is less than 7k/7 is less than -14/7

-8 is less than k is less than -2

Hope this helps!

Answer:

Step-by-step explanation:

-50 - 6 < 7k < -8-6

It took Jed a total of 1 2/3 hours to complete his homework altogether

Answer:

c) 2(x-2)+6=0

2(x-2)+6=0

Distribute

2x - 4 + 6 = 0

Combine like terms -4 + 6

2x + 2 = 0

Subtract both sides

2x = -2

Divide both sides

x = -1

Answer:

5 days 6hours

Step-by-step explanation:

Given data

total amount of flour=42kg

number of kg used per day=8kg

Since we are expected to know when she will need more, we need to divide the total flour by the daily usage, to know when the flour we be exhausted

divide 42 by 8 we have

42/8=5.25------0.25 days to hours is 6hours

So it will take 5 days 6hours

Answer:

Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

Step-by-step explanation:

In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.

Let us consider a random variable, X that follows a normal distribution, N (µ, σ²).

Then Z is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is,

[tex]Z=\frac{x-\mu}{\sigma}\sim N(0, 1)[/tex]

This, z-score is known as the standardized score.

It is provided that the distribution of finishing time for men (say, X) was approximately normal with mean µ = 242 minutes and standard deviation σ = 29 minutes.

The finishing time for Clay was x = 289 minutes.

Compute Clay's z-score as follows:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

   [tex]=\frac{289-242}{29}\\\\=1.67857143\\\\\approx 1.68[/tex]

Thus, Clay's standardized score is 1.68.

That is, Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

Answer:  The first aircraft has 208 seats.

The second aircraft has 119 and the third has 74.

Step-by-step explanation:

The equation is x+89 + x + x-45 = 401

combine terms: 3x + 44 = 401  Subtract 44 from both sides  3x=357  

divide both sides by 3

x= 119

substitute x in each term of the equation to find the number of seats on each aircraft

119 + 89 = 208 for #1    x= 119 for #2    119- 45= 74 for #3

Answer:

35000

Step-by-step explanation:

n 34519, the hundredth digit is 5 and so, rounding off 34519 to the nearest 1000 result in 35000.

Answer:

= 5y + 91

Step-by-step explanation:

because you multiply 13 * 7 which equals to 91

and then leave the 5y by yourself because there is no y to add or multiply

Answer:

BOTH THE QUESTIONS ARE SAME!!

When finding a perpendicular slope, you need to change the signs and flip the reciprocal

The answer to your question is:

m = -2

There are twelve months in a year, and he pays $1000 a month, so we get [tex]\$1000*12 = $12,000[/tex] spent in a year. He originally needed to spend $36,000, so he has [tex]\$36,000-\$12,000 = \$24,000[/tex] left.

Please mark as Brainliest if you found this helpful.

Answer:

He payed 12,000 in one year

John has to pay $24000

Step-by-step explanation:

Car cost = $36,000

He gave Monthly = $1000

How much money did he give in a year?

1 year = 12 months

So

$1000 x 12 = 12,000

How does he have balance?

$36,000 - $12,000 = $24,000

John payed $12000 in one year, and has to pay $24000 more to own the car.

Answer:

AC and AB both can't be perpendicular to line BC because if they were, then AB and AC would be parallel to each other and would never intersect. In this diagram, AB and AC intersect, so it it not possible.

Perpendicular lines meet at a right angle.

AB and AC cannot be perpendicular to BC because AB and AC are not parallel

From the diagram, we can see that line AB and line AC intersects at point A.

This means that both lines are not parallel

For any two lines to be perpendicular to a third line, the two lines must be parallel to each other.

So, we can conclude that:

Lines AB and AC cannot be perpendicular to line BC because both lines are not parallel.

Graph 1

coordinates : (0,-5) (-6,-2)

m = (y2-y1)/(x2-x1)

m = (-2-(-5))/(-6-0)

m = 3/-6 = -1/2

Substitute the values,

y = mx + c

-2 = (-1/2)(-6) + c

-2 = 3 + c

c = -5

Thus, equation is y = -1/2x -5

Graph 2

coordinates : ( 4,-2) (-5,3)

m = (y2-y1)/(x2-x1)

m = (3-(-2))/(-5-4)

m = 5/-9

Substitute the values,

y = mx + c

-2 = (-5/9)(4) + c

-2 = -20/9 + c

c = 2/9

Thus, the equation is y = -5/9 + (2/9)

Answer: $23,896

Step-by-step explanation:

In the year 2030, the number of years since the investment would be;

= 2030 - 2012

= 18 years.

As the question does not mention that the interest paid is compounded, simple interest will be used;

= Amount + (Amount * interest rate * number of years).

= 14,500 + ( 14,500 * 0.036 * 18)

= $23,896

Answer:

B. 18
