Answer:

3x + 21 or 21 + 3x

Step-by-step explanation:

Remark

This is an example of the distributive property. Of all the fundamental rules used in solving equations, this is likely the most important, at least at beginning levels.

Solution

What this is saying is two things.

1. you must multiply both terms on either side of the + sign by the factor outside the brackets.

2. You must not destroy a plus (or minus) sign unless the two terms inside the brackets are exactly the same.

3(7 + x)           The terms are not the same, so your answer must have a plus sign

Left side of the plus: 3*7

Right side of the plus: 3 * x

The answer then is 21 + 3x

It is more commonly written as 3x + 21

Answer:

m<C = 34.4 °

Step-by-step explanation:

From the question given above, the following data were obtained:

Opposite = AB = 35

Hypothenus = AC = 62

Angle C =?

The value of m<C can be obtained by using sine ratio as illustrated below:

Sine C = Opposite /Hypothenus

Sine C = 35 / 62

Sine C = 0.5645

Take the inverse of sine

C = Sine¯¹ 0.5645

C = 34.4 °

Thus,

m<C = 34.4 °

Answer:

£9095

Step-by-step explanation:

Given data

P=£8500

T= 3 years

R= 2.3%

The compound interest formula is

A= P(1+r)^t

substitute

A=8500(1+0.023)^3

A=8500(1.023)^3

A=8500*1.07

A=£9095

Hence the savings after 3 years is £9095

Answer:

120.

Step-by-step explanation:

Using the Pythagoras theorem:

(30√2)^2 = x^2 + x^2         where x =length of each side of the square

1800 = 2x^2

x^2 = 900

x = 30.

So the perimeter = 4*30 = 120.

Answer:

Slope=1

Step-by-step explanation:

The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Combine 13 1 3 and x x . Rewrite in slope-intercept form. Using the slope-intercept form, the slope is 13

Step-by-step explanation:

The number of birds in the park in 1997 is given by the equation A = 88.2 birds

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the number of birds in 1997 be represented as A

Now , the equation will be

The number of birds in 1995 x₀ = 80 birds

The time n = 1997 - 1995 = 2 years

The percentage of increase r = 5 %

The number of birds A is calculated by exponential growth factor ,

Substituting the values in the equation , we get

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( 2 ) = 80 ( 1 + ( 5/100 ) )²

On simplifying the equation , we get

x ( 2 ) = 80 ( 1 + 0.05 )²

x ( 2 ) = 80 ( 1.05 )²

x ( 2 ) = 80 x 1.1025

x ( 2 ) = 88.2 birds

Therefore , the value of A is 88 birds

Hence , the number of birds is 88 birds

Step-by-step explanation:

1. Pick two points on the line and use them to find the slope.

2. Then, find the coordinates of the y-intercept.

3. The y- coordinate is the value of b in the equation.

Answer:

Step-by-step explanation:

First find the slope of the line.

If the 2 points are (x1, y1) and (x2, y2) then the slope is (y2-y1)/(x2-x1).

Then we can use the point-slope form of the equation of the line:

y - y1 = m(x - x1)  where m = the slope and by substituting the point (x1, y1) we can  convert the equation to slope intercept form ( which is y = mx + b).

Example:

Find slope-intercept equation for the line joining  the points (1, 0) and (3, 4):

The slope = (4 - 0)/(3 - 1) = 4/2 = 2.

Now we plug in the slope m and the point (3, 4) into  y - y1 = m(x - x1):

y - 4 = 2(x - 3)       (Note we can use (1, 0) OR (3, 4) as they are both on line).

y - 4 = 2x - 6

y = 2x - 6 + 4

y = 2x - 2 which is slope-intercept form.

Answer:

24

Step-by-step explanation:

Answer:

You would use the distributive property.

Step-by-step explanation:

2(x+4) = 2x+8

2x+8x = 2x+8

10x = 2x+8

10x - 2x = 2x-2x+8

8x = 8

8x/8 = 8/8

x = 1

Answer:

y = 4x-13

Step-by-step explanation:

The standard equation of the line is y = mx+c

m is the slope

c is the intercept

Given the equation y = 4x+2

The slope m = 4

Substitute m = 4  and the given point into the formula y = mx+c

1 = 4(4)+c

1 = 14+c

c = -13

Get the equation

Recall that y = mx+c

y = 4x + (-13)

y = 4x-13

Hence the required equation is y = 4x-13

  - Now that we did that, you have to make it into a rule that makes sense, if we did [tex](y)[/tex] ÷ [tex](x)[/tex], the table would change. So to make it work you do the opposite of what we did to find the 10 value. This makes it multiplying [tex](x)[/tex] by 10.

So your answer is [tex]\bold{y=10x}[/tex].
