-4y = 72

Horozontal or vertical??

Answers

Vertical is the answer

Answer:

horizontal

Step-by-step explanation:

You want to know if the equation -4y = 72 describes a horizontal or vertical line.

Constant equation

The equation reduces to ...

-4y = 72

y = -18 . . . . . . . . divide both sides by -4

The points on a graph that have y-coordinate -18 will form a horizontal line. They are all 18 units below the x-axis. The line is parallel to the x-axis.

Additional comment

The equation x = constant describes a vertical line.

If you are in doubt, you can always graph the equation with your graphing calculator.

I dont need an answer I just need help.. The picture below, is it just 9x9 and like 6x6 or is it 9x2 and 6x2? And then the answer would be c x 2 or c x c?

Answers

Answer: 45

Step-by-step explanation:

Pythagorean Theorem is a^2+b^2=c^2
In this case it would be 9^2-6^2 which is 45

Answer:

In this case, it would be 9x9 and 6x6

Step-by-step explanation:

The ² in the problem means to multiply the number by itself, like 9x9. It's called the square.

a² + b² = c²

eg.

(a x a) + (b x b) must be = (c x c)

c = hypotenuse which means it is the longest part, which is why it is a² + b² = c²

s = 7

Concept Used:

Linear pair axiom

Step-by-step explanation:

(6s-8) + 90 + 8s = 180 (Linear pair axiom)

14s = 98

s = 7

Answer:

Step-by-step explanation:

The 3 angles are on a straight line, meaning the angle is 180°.

We know that one angle is 6s-8°, another is 8s°, and the middle angle is 90° because of the small box.

We can set up an equation to find s:

6s-8+8s+90=180

simplify

14s+82=180

subtract 82 from both sides

14s=98

divide both sides by 14

s=7

Firstly, you have to find the area of the whole shape. After that, you subtract that from the area of the individual triangle to get your answer.

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2

The area of the entire shape is 42yd^2

Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.

The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.

Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2

The area of the dotted triangle is 6yd^2

Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.

42-6= 36yd^2

Area of shaded region: 36yd^2 (i think)

Joseph has a fair dice with 4 faces numbered 1 to 4.
He also has a fair dice with 6 faces numbered 1 to 6.
He rolls both dice.
Find the probability of rolling a different number on each dice.

Answers

Answer:

To find the probability of rolling a different number on each dice, we can determine the total number of possible outcomes and the favorable outcomes.

The total number of possible outcomes when rolling a 4-sided die and a 6-sided die is the product of the number of sides on each die: 4 × 6 = 24.

The favorable outcomes occur when we roll a different number on each die. We can calculate this by considering all the possible combinations.

For the first die (4-sided), there are 4 possible outcomes.

For the second die (6-sided), there are 6 possible outcomes.

Since we want different numbers on each die, the total number of favorable outcomes is 4 × 6 = 24.

Therefore, the probability of rolling a different number on each die is:

Probability = (Number of favorable outcomes) / (Number of total outcomes)

Probability = 24 / 24

Probability = 1

Hence, the probability is 1 or 100%.

Suppose instead that one friend bought all 4 bags of pretzels and another friend bought all 4 drinks write an expression that shows the total cost

Answers

Could you provide all the information

Answer:

4x+4y=total cost

Step-by-step explanation:

We are given that there was a total of 4 bags of pretzels and 4 drinks bought. We are also given to write an expression using x dollars for the pretzels and y dollars for the drinks.

To do this, we need to multiply the cost of each pretzel bag, x, by the total amount of bags of pretzels purchased.

4·x

=4x

Next, we need to multiply the cost of each drink, y, by the total number of drinks purchased:

4·y

=4y

The question is asking us to write an expression, so put 2 and 2 together:

4x+4y=total cost

Given the actual question, "Suppose instead..." the expression would be the same.

Hope this helps! :)

What is 2x+21? Please it's due in about 15 minutes!!!

Answers

Answer:

The value of x is 21

Step-by-step explanation:

2x+21 is a linear equation with one unknown, x. To solve for x, we can use the following steps:

1. Subtract 21 from both sides of the equation. This will isolate x on the left-hand side of the equation.

```

2x+21 - 21 = x

```

2. Divide both sides of the equation by 2. This will divide both sides of the equation by 2, which will cancel out the 2 on the left-hand side of the equation, leaving x by itself.

```

x = (2x+21)/2

```

3. Simplify the right-hand side of the equation.

```

x = x/2 + 21/2

```

4. Combine like terms on the right-hand side of the equation.

```

x = (1/2)x + 21/2

```

5. Subtract (1/2)x from both sides of the equation. This will isolate x on the left-hand side of the equation.

```

x - (1/2)x = (1/2)x + 21/2 - (1/2)x

```

6. Simplify the right-hand side of the equation.

```

(1/2)x = 21/2

```

7. Multiply both sides of the equation by 2. This will multiply both sides of the equation by 2, which will cancel out the (1/2) on the left-hand side of the equation, leaving x by itself.

```

2*(1/2)x = 21/2 * 2

```

8. Simplify the right-hand side of the equation.

```

x = 21

```

Therefore, the value of x is 21.

2x+21
2x+21=0
-21/2
X = -21/2 or -10.5

2)there are heads and tails so the P of getting ont of them is half=1/2

4)there are 4 suits in a deck so 52/4=13; therefore, there are 13 hearts in the deck so 13/52=1/4

Answers

The total area of the figure is 52 square feet by adding the areas of the parallelogram and trapezoid

Calculating the total area

from the question, we have the following parameters that can be used in our computation:

parallelogram and trapezoid

Wher we have

Area of parallelogram = 7 * (6 - 2)

Area of parallelogram = 28

Also, we have

Area of trapezoid = 1/2 * (7 + 5) * 4

Area of trapezoid = 24

So, we have

total area = 28 + 24

total area = 52

Hence, the total area is 52 square feet

y is gonna increase by 5 every time so it’s 5(2), 5(3), 5(4) and so on

A 25-foot magazine rack begins 20 feet south of the checkout desk and continues south. What are the coordinates of the beginning and end of the magazine rack? Explain or show how you got your answer. ANSWER CORRECTLY WITH AN EXPLANATION

Answers

Answer: The coordinates of the beginning of the magazine rack are (0,-20), and the coordinates of the end of the magazine rack are (0,-45).

Explanation:

The magazine rack begins 20 feet south of the checkout desk, so its starting point is 20 feet below the x-axis. This gives us the coordinates (0,-20) for the beginning of the rack. Since the rack is 25 feet long, it extends 25 feet to the south of its starting point. Therefore, the endpoint of the rack is 20 feet (the starting point) minus 25 feet (the length of the rack), or -5 feet south of the checkout desk. This gives us the coordinates (0,-45) for the end of the rack.

Brainliest?

The given information tells us that the magazine rack begins 20 feet south of the checkout desk and continues south for a length of 25 feet. Since the magazine rack is only moving in the south direction, we can say that the x-coordinate (horizontal distance) of both points will be the same.

Let's assign the x-coordinate of the checkout desk as 0. Then, the x-coordinate of the beginning and end of the magazine rack will also be 0.

The y-coordinate of the beginning of the magazine rack is 20 feet south of the checkout desk, which means it is 20 feet less than the y-coordinate of the checkout desk. If we assume that the y-coordinate of the checkout desk is y = 0, then the y-coordinate of the beginning of the magazine rack is y = -20.

To find the y-coordinate of the end of the magazine rack, we add the length of the rack (25 feet) to the y-coordinate of the beginning of the rack (-20 feet). This gives us y = 5.

Therefore, the coordinates of the beginning of the magazine rack are (0,-20) and the coordinates of the end of the magazine rack are (0,5).
