the vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the y-axis to produce the image △ABC, find the coordinates of the vertex C

the coordinates of C are...

Answers

Answer:

(4, 2)

Step-by-step explanation:

Because ABC is reflected across the y-axis, this means that the y coordinate will remain the same, and the x coordinate is the negative of its original (because it is being flipped)

If the vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2). If ABC is reflected across the y-axis to produce the image △ABC, then coordinates of the vertex C is (4,2)

What is coordinate system?

a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other.

Given that,

Vertices of △ABC are A(-5,4),B(-2,4),and C(-4,2).

If ABC is reflected across the y-axis to produce the image △ABC.

We need to find the image of △ABC.

We need to find coordinates of vertex C.

As ABC is reflected across the y-axis, this means that the y coordinate will remain the same,

As the triangle is flipped the sign of x coordinate is the negative of its original.

Hence (4,2) is the coordinates of the vertex C.

Tell whether each number is a solution to the problem modeled by the following equation.

Mystery Number: Five more than −8 times a number is 29. What is the number?

Let the mystery number be represented by n. The equation is 5+(−8)n = 29.

Is 3 a solution to the equation?

Is −4 a solution to the equation?

Answers

Answer:

Neither are a solution.

Step-by-step explanation:

The thing is, -4 * -8= 32+5 =37, and you're looking for 29.

3*-8=-24+5=19. If you meant to put positive 8 and not negative, then 3 would be right, but other than that, neither are correct.

B 550
C 625
D 650

Answers

4. A
I seen the problem bf hope it helps

The calories from the different diets are given below.

1. 2,000 calories diet eat from veggies than from carbs is 200 calories.

2. 1,800 calories diet from fruit is 270 calories.

3. 2500 calorie diet, healthier because they eat more calories is not accurate.

4. 2200 calorie diet eat from protein is 550 calories. Then option B is correct.

What is the percentage?

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

1. The calories should a person on a 2,000 calories diet eat from veggies than from carbs will be

→ 2000 × 0.35 = 700 calories

→ 2000 × 0.25 = 500 calories

→700 – 500 = 200 calories

2. If a person is on a 1,800 calories diet, then the calories will come from fruit will be

→ 1800 × 0.15 = 270 calories

3. A person on a 2500 calorie diet states that they are healthier because they eat more calories from veggies will be

→ 2500 × 0.35 = 875 calories

Because veggies have more calories than others. Thus, inaccurate.

4. The number of calories from protein a person on a 2200 calorie diet should consume will be

→ 2200 × 0.25 = 550 calories

Just need a little help and explanation on this one. I always mess up and get confused, which causes me to feel stressed

Answers

first you will convert -2 1/3 to an improper fraction which will leave you with -7/3 - (-5) then you remove the parentheses which will change -7/3 - -5 to -7/3+5 since two negatives = a positive. Then make the denominators the same by multiplying 5 by 3, then you have -7+15
———
3

then you will subtract -7+15 to get you
8/3 and then simplify the improper fraction to get the difference of 2 2/3

your final answer is 2 2/3

Ben wants to go fishing on the lake

A boat rents for $12 per hour, and a rod and reel rent for $20 per day.

If Ben wants to spend no more than $80, how many hours can he soend fishing on the boat

Answers

Answer: Ben can only rent the boat for 5 hours.

Step-by-step explanation:

You have to set up an equation. It would be 20 + 12h = 80

20+12x=80

12x=80-20

Then divide both sides 12x=60

And you get 5

Ben can spend at most 6 hours (72 dollars) being on the boat.

Now if you wanna include the rod and reel, Ben can spend 29 hours (24 hours from the rod and reel, and 5 hours on the boat) Which all adds up to 80
