what is the sum of (-5a ^2 + a + 2) + ( 2a^2 - a - 9)

Answer:

3 different ways

Step-by-step explanation:

100 - 99.79 = 0.21

.21 = 2 dimes and 1 penny

.21 = 4 nickels and 1 penny

.21 = 1 dimes, 2 nickels and 1 penny

Answer:

without rounding, only the 1st one would be equal to 5

Step-by-step explanation:

31÷6.2=5

27.6÷5.2=5.307...

18.6÷4=4.65

6÷2.1=2.8

20.1÷4.1=4.9

BUT HEY, I HAVE PARANOIA AND THIS TIME I DIDNT CHECK LIKE A DOZEN TIMES SO MAYBE IM WRONG

oh and i forgot to say have a nice day or night or etc and good luck!

Answer:

31 / 6.2 = 5

Step-by-step explanation:

31/6.2 = 5

27.6/5.2 = 5.3

18.6/4 = 4.65

6/2.1 = 2.86

20.1/4.1 = 4.90

Answer:

( 0, 4 )

Step-by-step explanation:

midpoint formula: (x1 + x2/ 2, y1 + y2/ 2)

x1= -1

x2= 1

y1= 6

y2= -2

(-1 +1/ 2, 6 -2/ 2) -> (0,4)

hi <3

multiply the coefficient of x^2 with the last value:

2 x 3 = 6

you need to find a value that multiplies to give 6 and adds to give 5

this would be 3 and 2

now you have:

(x + 3)(x + 2)

we need to incorporate the 2 into it

you can divide the 2 by 2 so that part is fine. however, as 3 cant be divided by 2, you have to carry the 2 up as a coefficient for x

your final answer works out to be:

(2x + 3)(x + 1)

hope this helps :)

Answer:

no its not linear

Step-by-step explanation:

here is one example of a linear equation: y = 5x + 12

[tex]\large \mathfrak{Solution : }[/tex]

let's write the given equation in its slope intercept form :

i.e y = 6x + 8

by comparing to the general equation : y = mx + c

we get, slope (m) = 6

Answer:

x = -14

)Step-by-step explanation:

To find the value of x

Transpose

4(x + 2) = 3 (x - 2)

4x + 8 = 3x - 6

4x - 3x = -6 -8

x = -14

we can even cross check

putting the value of x by -14

4(x + 2) = 3 (x - 2)

4 (-14 +2) = 3 (-14 -2)

-56 +8 = -42 -6

-48 = -48

same = same

so CROSS-CHECKED

Answer:

x = -14

Step-by-step explanation:

4(x + 2) = 3 (x - 2)

4x + 8 = 3x - 6

x + 8 = -6

x = -14

Answer:

Mean- the average of data, meaning you add up all the numbers, and then divide the sum of the numbers by how many numbers there are. For example:

2, 2, 3, 4, 6, 6, 9.

7 numbers total.

2 + 2 + 3 + 4 + 6 + 6 + 9 = 32

32 ÷ 7 = 4.57

The mean would be 4.57.

Median- the middle point of the numbers. You cross off each of the numbers until you have one last number standing. If you have an even number of numbers, you find the middle of the last two numbers you crossed off. For example:

2, 2, 3, 4, 6, 6, 9

2, 3, 4, 6, 6

3, 4, 6

4

4 would be the median.

Mode- the largest number on the data.

Range- subtract the mode (largest number) from the smallest number to get range. For example:

2, 2, 3, 4, 6, 6, 9

9 - 2 = 7

7 would be the range.

Step-by-step explanation:

Answer:

Even numbers are integers that have 2 as a factor; odd numbers are all the other integers. Prime numbers are integers that have only themselves and 1 as factors. Perfect numbers are integers whose factors add up to the number. The smallest perfect number is 6 and its factors, 1, 2 and 3 add up to 6.

Step-by-step explanation:

The future value formula is FV=PV(1+i)^n, where the present value PV increases for each period into the future by a factor of 1 + i.  value PV increases for each period into the future by a factor of 1 + i. 

[tex]fv = pv {(1 + r)}^{n} [/tex]

fv = future value

pv = present value

Answer:

1 divided by 8 = 0.125 let's replace the 0 with a 2 since 2 is the whole number = 2.125 is correct

Step-by-step explanation:

Jeremy has mistaken 2 1/8 as 2.18 probably because he thought 1/8 was 0.18

The correct decimal value is 2.13.

We have Jeremy who incorrectly said that [tex]2\frac{1}{8}[/tex] is the same as 2.18.

We have Convert [tex]2\frac{1}{8}[/tex] to a decimal correctly.

The method to convert the mixed fraction to normal fraction is -

[tex]5\frac{2}{3}\\[/tex] = [tex]\frac{3\times 5 +2}{3} = \frac{17}{3}[/tex]

According to question, we have -

Mixed fraction = [tex]2\frac{1}{8}=\frac{17}{8}[/tex] = 2.125 = 2.13

Hence, the correct decimal value is 2.13.

Standard: 238,900

Expanded: 200,000 + 30,000 + 8,000 + 900

Step-by-step explanation:

The distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the distance from the earth to the moon is two hundred thirty-eight thousand, nine hundred miles.

The number in standard form will be written as below:-

Standard form = 238,900

The number in the expanded form will be written as below:-

Expanded form = 200,000 + 30,000 + 8,000 + 900.

Therefore, the distance in standard form is 238,900 and in expanded form is 200,000 + 30,000 + 8,000 + 900.
