On Thursday the high temperature was 0°C. If it was three degrees colder on Friday what was the temperature

Answer:

1.08 x 10³

Step-by-step explanation:

Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.

Follow the steps below to see how 1,080 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 1,080

New Number: 1.080

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 0 8 0

Decimal Count: 1 2 3

There are 3 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.08 (Please notice any zeroes on the end have been removed)

b = 3

Now the whole thing:

1.08 x 10³

Step 4

Check your work:

10³ = 1,000 x 1.08 = 1,080

Answer:

Step-by-step explanation:

x   - first number

2x   - twice the first number

twice the first number exceeds the second number by 4 so:

2x-4   -the second number

y - the third number

the second number is equal to the sum of the first and third numbers:

2x-4 = x + y

x + y = 2x - 4

  -x        -x

y = x - 4       - the third number

the sum of three numbers:

x + 2x-4 + x-4 = 4x - 8

The sum of three numbers is 12 so:

4x - 8 = 12

   +8       +8

  4x = 20

  ÷4    ÷4

   x = 5

2x-4 = 2•5 - 4 = 6

x-4 = 5 - 4 = 1

Check:

5+1 = 6

2•5 = 10,  10-4 = 6

Answer: 4

Step-by-step explanation: First convert the equation to y = mx + b form.

Start by subtract 4x from both sides to get -y = -4x + 3.

From here, divide both sides by -1 to get y = 4x - 3.

Now in y = mx + b form, the slope is the multiplier, or the m.

So here, 4 is the slope.

Answer:

(D) 4

Step-by-step explanation:

In order to find the slope you need to rearrange the equation so that y is alone on one side, so:

4x - y = 3

-y = -4x + 3

y = 4x - 3

The slope is the coefficient in front of x, so the slope is 4

Answer:

m = 6

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply choose 2 points and plug them into the formula to find slope m:

(1, 20)

(2, 26)

[tex]m=\frac{26-20}{2-1}[/tex]

[tex]m=\frac{6}{1}[/tex]

m = 6

Answer:

x>−3/7

Step-by-step explanation:

I hope this helps you

Hey there! I'm happy to help!

To find the x value of the midpoint, you add the x values and divide by 2.

-5+4=-1

-1/2=-1/2

For the y value, you add the y values and divide by 2.

5+6=11

11/2=5 1/2

So, the midpoint is (-1/2, 5 1/2).

Have a wonderful day! :D

Answer:

y= -6+2/3x

Step-by-step explanation:

2x-3y=18

Minus the 2x from both sides

-3y=18-2x

Then divide both sides by -1

-3y÷-1=18÷-1 -2x÷-1

Lastly divide both sides by 3

3y÷3= -18÷3+2x÷3

The equation 2x - 3y = 18 can be written as y = (2/3)x - 6 after arranging the terms and making subject y.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation is:

2x – 3y = 18

2x - 3y = 18

-3y = 18 - 2x

y = (2/3)x - 6

Thus, the equation 2x - 3y = 18 can be written as y = (2/3)x - 6 after arranging the terms and making the subject y.

Answer:

the mode is 78 out of all the numbers

Answer: Choice A) He wrote it incorrectly. He should have gotten 6.

This is because exponents of 1/2 are the same as square roots.

[tex](36)^{1/2} = \sqrt{36} = 6[/tex]

Matt probably thought it was 36 times 1/2, which may explain how he got 18.

Matt rewrote the expression incorrectly. The expression is equivalent to 6. Option A is correct.

Given that,
Matt rewrote the given expression, he got 18. [tex](36)^{1/2}[/tex] Which statement is correct is to be determined.

In mathematics, it deals with numbers of operations according to the statements.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Since matt made a mistake in his calculation, let correct the calculation and determined what should be the matt mistake.

Simplification
[tex]= (36)^{1/2}\\= (6^2)^{1/2}\\=(6)^{2 * 1/2}\\= 6[/tex]

Thus, Matt rewrote the expression incorrectly. The expression is equivalent to 6. Option A is correct.

Answer:

I believe the answer would be 64w2.

Step-by-step explanation:

8 squared is 8 x 8, which equals 64, and then w squared is just w2, since we don't know what it is. Put them together, and the answer is 64w2.
