how to round 768 to the nearest hundred.

Calculate f(3) by replacing X with 3:

f(x) = x^2 -1

f(3) = 3^2 -1

F(3) = 9-1

f(3) = 8

Now calculate f(-4) by replacing x with -4:

f(x) = x^2 -1

f(-4) = (-4)^2 - 1

f(-4) = 16 -1

f(-4) = 15

Now add f(3) to f(-4)

8 + 15 = 23

The answer is a) 23

Ask your teacher for help and if he/she is the type of teacher who's lazy get a tutor it's better to have someone explain it to you to understand better then only knowing half of it. ((:

We can find the maximum number of CDs she can buy by dividing 153 by 18. The answer ends up being 8.5. Since she can't buy 0.5 of a CD, she can buy a maximum of 8 CDs. Written as an inequality, I think it should be x is less than or equal to 8. I hope this helps!

The formula of a midpoint:

[tex]M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)[/tex]

We have:

[tex]M(-6,\ 8)\to x_M=-6,\ y_M=8\\A(-2,\ 10)\to x_A=-2,\ y_A=10[/tex]

Substitute:

[tex]\dfrac{-2+x_B}{2}=-6\qquad|\cdot2\\\\-2+x_B=-12\qquad|+2\\\\x_B=-10\\\\\dfrac{10+y_B}{2}=8\qquad|\cdot2\\\\10+y_B=16\qquad|-10\\\\y_B=6[/tex]

Step-by-step explanation:

Answer: 1/2.

Explanation:

First, note that since the previous drops have already happened, their result do not modify the occurrence of future results when the toast is dropped again.

In oder to have a total of three time landing butter side up, exactly, there are two possibilities:

Since there are two ways of totaling side up 3 times, you have to sum both chances.

1) Next drop butter side up and second drop butter side down:

     1/2 × 1/2  = 1/4

2) Next drop butter side down and second one butter side up:

     1/2 × 1/2 = 1/4

3) Add both probabilities: 1/4 + 1/4 = 1/2

And that is the answer: 1/2

Hey there! Welcome to Brainly

We see that Damian earns $8 for every hour he works. This means that when x=1, Damian will earn 8 dollars, 2 he will earn $16, etc.

Since he constantly adds 8 every hour, it would look like this.

8+8+8+8+8+8+8.....

This is an example of multiplication.

The thing is, we are not sure how many 8's we are adding.

We can use the variable "x" to represent ANY number of 8's, or hours he worked.

We would multiply this x by 8 to show that he will earn $8 for EACH number of hours he works.

8 x x

The problem is, we cannot write our multiplication sign like this, because it looks just like our x we are using.

We can rewrite our multiplication symbol using · or we can just put our x right next to the eight. When a variable is right next to a constant, or number without a variable, it turns it into a mini multiplication equation, but in a simplified form.

8x

Now, we need to write this as an equation. We need to say that something else is equal to 8x. We could say, his money, which we can represent with as d.

Therefore, we could write our equation as d= 8x.

I hope this helps! Have a day as sweet and fresh as lemonade! :)

Answer:

-1 1/4

Step-by-step explanation:

Do it in pieces. Everything is divisible by 3, so you can do it in your head.

... (-3 3/4)/3 = (-3/3) -(3/4)*(1/3) . . . . . an integer part divisible by 3, and a fraction divisible by 3

... = -1 -(3*1)/(3*4) . . . . factors of 3 cancel

... = -1 -1/4

... = -1 1/4

_____

Hopefully, it's no mystery that 3 quarters divided by 3 is 1 quarter, just as (3 whatever) divided by 3 is (1 whatever).

_____

It really does help to play with blocks, Legos, chips, coins, rocks, or counters of any kind. Arrange them, deal them into piles, put them is rectangles or triangles (and be aware of how many you use). It also helps to cook from recipes that require use of fractional measures. The cups and spoons give you a sense of what size fractions are larger/smaller, and how they are related. Appropriate play with counting and arranging and measuring can help you develop your number sense, and help you learn to do problems like this in your head.

Hey there!!

The basic slope-intercept formula :

y = mx+ b where ' m ' is the slope and ' b ' is the slope-intercept.

Given equation : 7x - 2y = 8

We will have to isolate the ' y '

... 7x - 2y = 8

Subtract 7x on both sides

... -2y = -7x + 8

Divide by - 2 on both sides

... y = ( 7x / 2 ) - 4

Hence,

slope = 7/2 = 3.5

y-intercept = ( 0 , -4 )

Hope it helps!!

Answer:

s can take any real value.

Step-by-step explanation:

Given that

-2(6+s)_>-15-2s

Distribute -2 over 6+s

-12-2s >= -15-2s

Simplify both the sides

Add 2s to both the sides.

We get 2s cancel out and -12>=-15 which is true.

Hence the given inequality is valid for all values of s.

This is a special case of inequality which has infinite number of solutions.

s can take any real number and this inequality is valid.

Answer:

Solution of inequality: -12 ≥ -15 Which is true.

Step-by-step explanation:

Given data:

Equation:-2(6+s)_>-15-2s

-2(6+s)_>-15-2s

=-12 - 2s ≥ - 15 -2s

By dividing -2s on both sides:

= -12 - 2s/-2s ≥ - 15 -2s/-2s

= -12 ≥ -15

                                                  -2(6+s)_>-15-2s =  -12 ≥ -15

Hello  Beathegggirlboss101

The answer would be the 126th person

We have to find what would be divisible to 7 and 18.

Trying to divide 126 by 7 and 18 (different problems) would get the answer

:)

The 126th person will be the first to get both coupons.

Explanation: The lowest common factor of 7 and 18 is 126 (which means the number that 7 and 18 multiply into.)

Hopefully this makes sense and was helpful. (:

6396÷15=426.4

15 will go into 63 4 times with 3 left

bring down the 9 now you have 39 and 15 will go into it 2 times with 9 left

bring down the 6 you have 96 and 15 will go into that 6 times with 6 left

put you decimal after the 6 and bring down a 0

60 ÷ 15 =4

0 remainder

For m it’s 1,1/3and -5/3 you will get different values when plug the different values of n

n = -4/9 hope this helps

n-2=10n+4/2

We move all terms to the left:

n-2-(10n+4/2)=0

We add all the numbers together, and all the variables

n-(10n+2)-2=0

We get rid of parentheses

n-10n-2-2=0

We add all the numbers together, and all the variables

-9n-4=0

We move all terms containing n to the left, all other terms to the right

-9n=4

n=4/-9

n=-4/9

For this case we have:

m represents the total cost of each meal. If people do not pay a tip, the total cost to pay would be:

[tex]m + m + m = 3m\\[/tex]

Person 1:

Without tip the cost of your meal is m.

You want to pay 10% tip

m -------------------> 100%

x --------------------> 10%

[tex]x =\frac{(10)(m)}{100} = 0.1m\\[/tex]

Thus, its cost will be:

[tex]C1 = m + 0.1m = 1.1m\\[/tex]

Person 2:

Without tip the cost of your meal is m.

m -------------------> 100%

x --------------------> 15%

[tex]x =\frac{(15)(m)}{100} = 0.15m\\[/tex]

Thus, its cost will be:

[tex]C2 = m + 0.15m = 1.15m\\[/tex]

Person 3:

Without tip the cost of your meal is m.

m -------------------> 100%

x --------------------> 20%

[tex]x =\frac{(20)(m)}{100} = 0.20m\\[/tex]

Thus, its cost will be:

[tex]C3 = m + 0.20m = 1.20m\\[/tex]

Thus, the total cost to pay will be:

[tex]C = 1.1m + 1.15m + 1.20m\\[/tex]

Answer:

[tex]C = 1.1m + 1.15m + 1.20m[/tex]

204

71:35=2

2 goes on the top

2x35=70

71-70=1

then carry them down 14

14:35=0

Carry it up it should be 20 up there now

Carry the 0 from the 7140 down to make it 140

140:35=4

Then carry that 4 up and your answer is 204

76x+608-2=13

76x+606=13

76x= -593

x= -7.8

How to get answer:

Step 1: Simplify both sides of the equation.

38(2x+16)−2=13

(38)(2x)+(38)(16)+−2=13(Distribute)

76x+608+−2=13

(76x)+(608+−2)=13(Combine Like Terms)

76x+606=13

76x+606=13

Step 2: Subtract 606 from both sides.

76x+606−606=13−606

76x=−593

Step 3: Divide both sides by 76.

[tex]\frac{76x}{76} = \frac{-593}{76}[/tex]

Answer:

Decimal Form: −7.80263157…

Fraction Form: [tex]\frac{-593}{76}[/tex]

Mixed Number Form: [tex]-7\frac{61}{76}[/tex]

5 1/2 + 12 (1 1/4)

= 5 1/2 + 12 (5/4)

= 5 1/2 + 53/4

= 11/2 + 53/4

= 22/4 + 53/4

= 75/4

= 18 3/4

Answer:  18 3/4 inches

This problem can be solved using proprtions.  Once you set up the proportion, the calculations are easy.

Let x = number of pens made in 1 second.

[tex]\frac{9pen}{3sec} = \frac{xpen}{1 second}[/tex]

Now, you just cross multiply and solve.

9 = 3x

x = 3

The rate is 3 pens per second.

63 seconds is 90% of Niki's time for one lap. So, Niki's time for one lap is 63/0.9, which equals 70 seconds or 1 min. 10 seconds.
