Answer:

No

Step-by-step explanation:

The correct answer is -406,726

A negative minus a negative is the same as a negative plus a positive

-621,044 + 214,318 = -406,726

The statement [tex]log_{2} 4 + log_{2} 8 = 5[/tex] is true.

We have been given two logarithm terms that is the first term is [tex]log_{2} 4[/tex] and second term is [tex]log_{2} 8[/tex].

The properties of logarithm that we are going to use are

          [tex]log a^{m} = m *log a[/tex]  and [tex]log_{a} a = 1[/tex]

First we will find the value of the two terms by operating the above mentioned properties of logarithm to obtained the values of the logarithm.

Thus,

                          [tex]log_{2} 4 = log_{2} 2^{2} \\ = 2* log_{2} 2\\ = 2*1\\ = 2[/tex]

Similarly,    

                            [tex]log_{2} 8 = log_{2} 2^{3} \\ = 3* log_{2} 2\\ = 3*1\\ = 3[/tex]        

Now adding both the terms by substituting its respective values which we have calculated above, we get

                   [tex]log_{2} 4 + log_{2} 8 = 2+3 = 5[/tex]  

Thus,  we have proved that    R.H.S = L.H.S  

Hence the statement is  [tex]log_{2} 4 + log_{2} 8 = 5[/tex] is true.

Answer:

option 4 and option 3

Step-by-step explanation:

(3)

using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

[tex](x^{\frac{3}{2}) } ^{6}[/tex]

= [tex]x^{\frac{3}{2}(6) }[/tex]

= [tex]x^{9}[/tex]

(4)

using the rule of exponents/ radicals

[tex]x^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{x^m}[/tex] , then

7[tex]x^{\frac{2}{3} }[/tex]

= 7 × [tex]\sqrt[3]{x^2}[/tex]

= 7 [tex]\sqrt[3]{x^2}[/tex]

Answer: ab = 3a + 2b + c subtract 3a from both sides. ab - 3a = 2b + c factor the left side. a (b - 3) = 2b + c divide both sides by ( b - 3).

============================================================

Explanation:

[tex]g_3 = 6.25[/tex] tells us that the third term is 6.25

The common ratio r = 5/4 = 1.25 tells us how to get the next term. We multiply the third term by 1.25 to get the next term

4th term = (3rd term)*(r) = (6.25)*(1.25) = 7.8125

--------------

To go backwards and find the second term, we will divide by r, which is the inverse operation of multiplication.

2nd term = (3rd term)/r = (6.25)/(1.25) = 5

Use the same idea to find the 1st term

1st term = (2nd term)/r = 5/(1.25) = 4 is the final answer

The equation that best fits all the points on the graph is y = -2x + 3.

The line of best fit is a line that can be drawn to connect most of the points on the graph. In other words, it best fits the points.

Using a linear regression tool, input the coordinates that are on the graph including:

(-4, 10) (-2, 8) (-1, 5) (1, 3) (2, 0) (2, -3)

The formula you get for line of best fit would be:

y = -2.08564x + 3.01259

she needs to make 12 visits to the movie theatre to earn the rest of the 145 points and get a free movie ticket.

We are given that:

Jocelyn received 25 reward points just for signing up.

She earns 12.5 points for each visit that she makes to the movie theatre.

The free movie ticket is available when she has 170 points with her.

Points to be collected more for a free movie ticket will be:

Points = 170 points - 25 points = 145 points.

So, the number of visits she has to make to the movie theatre will be calculated with the help of division.

Number of visits = 145 points / 12.5 points

Number of visits = 11.6 visits that is 12 visits.

Therefore, she needs to make 12 visits to the movie theatre to earn the rest of the 145 points and get a free movie ticket.

The slope and y-intercept of the line are  -3 and -6 respectively.

The graph is a linear function.

The graph can be represented in a slope intercept form as follows;

y = mx + b

where

Therefore, using (1, -9)(-4, 6)

m = 6 - (-9) / -4  - 1

m = 6 + 9 / -5

m = 15 / -5

m = -3

Therefore,

slope = -3

Let's find the y-intercept as follows;

(1, -9)

y = -3x + b

-9 = -3(1) + b

b = -9 + 3

b = -6

Step-by-step explanation:

parallel means it has the same slope.

the slope is always the factor of x : -3/2

I guess the needed equation is in slope-intercept form :

y = ax + b

"a" being the slope, "b" being the y intercept (the y value when x = 0).

but since we have a point on the line and its slope, we can start with the point-slope form

y - y1 = a(x - x1)

"a"is again the slope, (x1, y1) is the given point.

and then we transform this into the slope-intercept form.

in our case we have

y - -1 = -3/2 × (x - 6)

y + 1 = -3x/2 + 18/2 = -3x/2 + 9

y = -3x/2 + 8

or

y = -3/2 x + 8

y = -1/2 × (3x - 16)

The subtraction of the expression 10√27 - 4√12 is 22√3.

Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.

In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.

Consider the expression,

y = 10√27 - 4√12

Now, the number in the root can also be written as:

27 = 3 × 3 × 3

12 = 2 × 2 × 3

Therefore,

y = 10√27 - 4√12

y = 10[ √(3 × 3 × 3) ] - 4[ √( 2 × 2 × 3 ) ]

y = 10 × 3√3 - 4 × 2√3

Answer:

10 x^3 - x^2 - 29 x - 30 = (10 x + 9)(x^2 - x - 2) + -12

Step-by-step explanation:

Compute (10 x^3 - x^2 - 29 x - 30) ÷ (x^2 - x - 2) using polynomial long division:

x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30

To eliminate the leading term of the numerator, 10 x^3, multiply x^2 - x - 2 by 10 x to get 10 x^3 - 10 x^2 - 20 x. Write 10 x on top of the division bracket and subtract 10 x^3 - 10 x^2 - 20 x from 10 x^3 - x^2 - 29 x - 30 to get 9 x^2 - 9 x - 30:

| | | | | 10 x | |

x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30

| -(10 x^3 | - | 10 x^2 | - | 20 x) | |

| | | 9 x^2 | - | 9 x | - | 30

To eliminate the leading term of the remainder of the previous step, 9 x^2, multiply x^2 - x - 2 by 9 to get 9 x^2 - 9 x - 18. Write 9 on top of the division bracket and subtract 9 x^2 - 9 x - 18 from 9 x^2 - 9 x - 30 to get -12:

| | | | | 10 x | + | 9

x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30

| -(10 x^3 | - | 10 x^2 | - | 20 x) | |

| | | 9 x^2 | - | 9 x | - | 30

| | | -(9 x^2 | - | 9 x | - | 18)

| | | | | | | -12

The quotient of (10 x^3 - x^2 - 29 x - 30)/(x^2 - x - 2) is the sum of the terms on top of the division bracket. The remainder is the expression that remains after the final subtraction step.

| | | | | 10 x | + | 9 | (quotient)

x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30 |
