Find x value for the point that splits segment CD in half if point C is located at (−2, 4) and point D is located at (3, 7).

Answers

The x value is 1/2, or 0.5

Just use the midpoint formula
(x2+x1)/2 , (y2+y1)/2

to find the midpoint. The x value would be (x2+x1)/2, so plug in the numbers.
(-2+3)/2 = 1/2

Answer:

[tex]\text{The x value for the point that splits segment CD in half is }\frac{1}{2}[/tex]

Step-by-step explanation:

Given two points C(-2,4) and D(3, 7)

we have to find the value of x-coordinate for the point that splits segment CD in half.

By mid-point formula,

The coordinate of mid-point of line segment joining the points (a,b) and (c,d) are [tex](\frac{a+c}{2}, \frac{b+d}{2})[/tex]

Coordinates of mid-point joining the points C(-2,4) and D(3, 7)

I WILL GIVE BRAINLIEST TO WHOEVER IS CORRECT.

Answers

In a function, each x-coordinate can be used only once.
If you have two points, one above the other on the same vertical line, it is not a function.
You are correct.

The upper, right-hand graph represents a function. Why? Because there is never more than one value of y for any given x.

If you use the vertical line test on the other 3 problems, you'll see that for some x, the line goes thru more than just one black dot.

The distance between bills house and his aunts house is 485 miles about how many miles would bill drive if he made 4 round trips from his house to his aunts house

Answers

He would have made 1,940 miles in total

Answer:

3880 miles

Step-by-step explanation:

Distance between Bill's house and his Aunt house = 485 miles

Distance traveled in one round trip = two times the distance between the Bill's house and his Aunt house

Distance traveled in one round trip = 2 x 485 = 970 miles

So, the distance traveled in 4 round trip = 4 x 970 = 3880 miles.

Thus, the distance traveled by teh bill in 4 round trips is 3880 miles.

kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 36. How old is each sister?
A model to help you start your equation as: Kim’s age + Sister’s age = 36
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence

Answers

   A. 2x+x=36
        x=12

B. 2(12)+12=36
      24+12=36

C. Brainliest if satisfied :D

a)
Let x = sister's age
Kim's age is twice that of her sister
so Kim's age = 2x
Kim’s age + Sister’s age = 36
equation:
x + 2x = 36

b) solve the equation x + 2x = 36

x + 2x = 36
3x = 36
x = 36 / 3
x = 12
Kim's age = 2x = 2(12) = 24

answer
Sister's age is 12 and Kim's age is 24.

How to turn Standard Form ( -x + 2y = 10) to Point slope form?

Answers

Point slope form (slope intercept form) is y = mx + b

so first move the -x over to the other side

2y = x + 10

Divide 2 to both sides

2y/2 = y
(x + 10)/2 = x/2 + 5

slope intercept form
y = x/2 + 5

Describe the solutions of 4 + n > −2 in words.

The value of n is a number less than −6.
The value of n is a number greater than or equal to −7.
The value of n is a number equal to −7.
The value of n is a number greater than −6.

Answers

Final answer:

The solution to the inequality 4 + n > -2 is n > -6. This means the value of n can be any number that is greater than -6.

Explanation:

The inequality 4 + n > -2 can be solved to find the solution for 'n.' Start by subtracting 4 from each side of the inequality to isolate 'n.'

Here's the step-by-step calculation: 4 + n > -2 becomes n > -6 when we subtract 4 from both sides.

So, the value of n is any number that is greater than -6. In other words, n can be just a little bit more than -6, -6.01 for example, or it can be a much larger number, like 1, 100, or 1000, etc.

Reggie lost 4 spaceships in level 3 of a video game. He lost 30 points for each spaceship. When he completed level 3, he earned a bonus of 350 points. By how much did his score change?

Answers

his score changed by 320. to get the answer, just subtract 30 from 350 and you get 320.

He lost 4 spaceships, each subtracting 30 points

4(-30) = -120

On completing, he earned a bonus of 350 points
0 + 350 = 350

Subtract the amount of points he lost from the bonus

350 - 120 = 230

His score has a positive 230, or x (total points he gotten) plus the bonus

x + 230

A local grocery store sells oranges $1.15 per pound, tax included. A shopper buys 1.3 pounds of oranges from the store. Rounded to the nearest cent, how much does the shopper pay for the oranges?

Answers

the price for one pound is $1.15

to find the total cost you need to multiply the cost of one pound by the total weight of how much was bought

they bought 1.3 pounds, so multiply 1.3 by 1.15 for the total cost

1.15 * 1.3 = 1.495 which rounds up to $1.50

the shopper paid $1.50

what is to 20 ≥ 4/5w

Answers

20 ≥ 4/5w
w<= 20 (5/4)
w <= 25

hope it helps

Final answer:

The inequality 20 ≥ (4/5)w represents a comparison between a number and a variable multiplied by a fraction. To solve it, you isolate the variable. The solution is w <=25.

Explanation:

The inequality 20 ≥ (4/5)w represents a mathematical statement comparing a number, 20, with a variable, w, multiplied by a fraction, 4/5. The inequality sign, ≥, indicates that 20 is greater than or equal to the result of the multiplication. To solve this inequality, you need to isolate the variable on one side of the inequality sign.

To get rid of the fraction, multiply both sides of the inequality by the reciprocal of 4/5 which is 5/4. This gives you (5/4) * 20 ≥ (5/4) * (4/5)w which simplifies to 25 ≥ w.

Therefore, the solution to the inequality is w <=25.

The best way to start would be to see if you can make the hundred's values the same for both numbers. The only two repeating values are 9, therefore your number should start with 9. the next thing is to find the closest tens values. this is 6 and 7. so one number with be 96x and the other 97x. Next you will then find and insert either 4 or 1 into the numbers and find which difference between the two combinations is the smallest, either (964 - 971 or 961 - 974)

Prepare you response to this question when you are ready you may submit your response

Requirements: include various key words you learned within this unit.
list your steps in order so that anyone can follow

Answers

Use the order of operations in order to simplify (solve) the expression

-12 ÷ 3 x (-8 + (-8) - 6) + 2 Original expression
-12 ÷ 3 x (-16- 6) + 2 Inside the parenthesis do the addition of the first negatives. -8 +-8 = -16
-12 ÷ 3 x (-22) + 2 Inside the parenthesis subtract -16-6 = -22
-4 x (-22) + 2 Multiplication and division is worked from left to right. -12 divided by 3 is -4
88 +2 Multiply -4 x -22 = 88. Two negatives make a positive with multiplication.
90 Addition 88 + 2 = 90

The expression must be simplified using the order of operations. In this case, the terms inside the parenthesis should be simplified first. Within the parenthesis, there is a nested parenthetical term, which is simplified before the rest of the term inside the parenthesis. The +(-8) term simplifies to -8. The terms inside the parenthesis then become (-8-8-6), which is equal to -22. Then, multiplication and division are performed next, in order as they appear. So -12/3 is equal to -4. Then, -4 is multiplied by the -22 from the parenthetical expression to equal 88. Then, addition and subtraction are the final steps in the order of operations, so the 2 is added to the 88, for a total of 90.

help! 65-32/8 (/=divided by)

Answers

Final answer:

The calculation 65 - 32/8 follows the order of operations, starting with division and then subtraction. Dividing 32 by 8 gives 4, and subtracting this from 65 gives a final answer of 61.

Explanation:

To solve the equation 65 - 32/8, you need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Firstly, you handle the division. You divide 32 by 8 to get 4.

Then, you subtract the result from 65. So, 65 minus 4 equals 61.

The answer to the calculation 65-32/8 (/=divided by) is 61.
