Answer:

8x + 4y

Step-by-step explanation:

3(x + y) + 5x + y

3x + 3y + 5x + y....... distribute 3 to both variables in the parenthesis

8x + 4y....................... combine like terms

Answer

8x+4y

Step-by-step explanation:

First you expand the 3(x+y) by multiplying 3 with x+y

So it becomes 3x+3y

Now your new expression will be 3x+3y+5x+y

After that, you combine the like terms, 3x and 5x are like terms, 3y and y are like terms.

So it will become 3x+5x+3y+y

You can add the like terms up, so 3x+5x=8x and 3y+y =4y

The simplified expression will be 8x+4y

Answer:

2x - y = - 8

Step-by-step explanation:

y - 4 = 2(x + 2) ← distribute

y - 4 = 2x + 4 ( subtract y from both sides )

- 4 = 2x - y + 4 ( subtract 4 from both sides )

- 8 = 2x - y , that is

2x - y = - 8 ← in standard form

with A = 2, B = - 1 and C = - 8

Step-by-step explanation: Depositing is the act of putting money inside the bank account usually to gain interest.

If John started with $75, you add his deposit ($7) which comes out to 82. Then add 82+7 which equals 89 and so on.

75+7= 82

82+7= 89

89+7= 96

Equivalent Expression:  [tex]\displaytext\mathsf{\frac{a^7}{b^8}}[/tex]

Step-by-step explanation:

Given the exponential expression,  [tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}}[/tex]:

We could use the Quotient Rule of Exponents where it states that:

[tex]\displaystyle\mathsf{\frac{a^m}{a^n}\:=\:a^{(m\:-\:n)}}[/tex]

Since we have the variables, a and b as the base, we could simply apply the Quotient Rule and subtract their exponents.

[tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}\:=\:a^{(12\:-\:5)}\:b^{(-3\:-\:5)}}[/tex]

[tex]\displaytext\mathsf{=\:a^{7}\:b^{-8}}[/tex]

Next, we must transform the negative exponent of base, b, into positive by applying the Negative Exponent Rule, where it states that:

[tex]\large\text{$ a^{-n}\:=\:\frac{1}{a^{n}} $}[/tex]

Applying the Negative Exponent Rule will result in the following exponential expression:

[tex]\LARGE\text{$ a^{7}\:b^{-8}\:=\:[a^{7}\:\times\:\frac{1}{b^8}]\:=\:\frac{a^7}{b^8} $}[/tex]

Therefore, the equivalent expression is:  [tex]\LARGE\text{$ \frac{a^7}{b^8} $}[/tex].

Answer:

63°

Step-by-step explanation:

Angle sum property = 180°

=> 19 + 98 + x = 180

=> x = 180 - 117 = 63°

Answer:

Step-by-step explanation:

Given,

Measurement of one angle of a triangle = 19°

Measurement of 2nd angle of the triangle = 98°

Let,

The third angle be = x

As we know,

Sum of all the angles of a triangle is 180°

Therefore,

By the problem,

=> 19° + 98° + x = 180°

=> x = 180 - 98 - 19

=> x = 63

Hence,

The measurement of 5he third angle of the triangle is 63° (Ans)

Answer:

Step-by-step explanation:

Old weight = 60 pound

New weight = 80 pound

Finding:

Percent of increase in weight

Therefore:

Percent of expansion in weight = [(New weight - old weight)/Old weight]100

Percent of expansion in weight = [(80 - 60)/60]100

Percent of expansion in weight = [(20)/60]100

Percent of expansion in weight = 33.33% Approx.

Answer:

Answer:

Z and X is incorrect

The given quadratic function for the restaurant sales indicates that the sale first reduces then increases.

Reasons:

The function for the sales in the restaurant is y = 3·x² + 3.2·x + 514

Where;

y = Sales in billions of dollars

x = Number of years since 2008

Required:

The year in which the restaurant industry food and drink sales will be $1212 billion.

Solution:

When the food and drink sale is $1212 billion, we have;

1212 = 3·x² + 3.2·x + 514

Which gives;

3·x² + 3.2·x + 514 - 1212 = 0

3·x² + 3.2·x - 698 = 0

Factorizing with a graphing calculator gives;

(x + 15.796)·(x - 14.729) = 0

x = -15.796, or x = 14.729

The time will have a natural number value, therefore the positive value of x

= 14.729 is used.

Therefore, the number years since 2008 at which the restaurant sales will

be $1212 billion is approximately 15 years.

The year at which the sales will be $1212 billion = 2008 + 15 = 2023

Answer:

after 13 hours

Step-by-step explanation:

Since the monthly fee is $4.25

so

● $4.25 + ( 2.75 × Number of hours) = 40

● ( 2.75 × Number of hours) = $40 - $4.25

● 35.75/ 2.75 = 13

Answer:

Linear

Step-by-step explanation:

This is linear because using the data you have provided we can work out that the equation is y= -5x+27

y= mx+ c (c is the gradient)

This equation shows that the line is straight (also shown in the picture) and therefore must make it a linear graph.

For the graph to be non linear, the graph would be curved but this would mean the equation would have to be a quadratic - which it isn't.
