How do I solve this

Answer:

x=-6

Step-by-step explanation:

-8(x+3)=24 first, divide both sides to get x+3=-3

then move the constant to the right and change its sign to get x=-3-3 and calculate to get your answer.

Answer:

$20.57

Step-by-step explanation:

36.57 x 125% (or 1.25) = $45.7125

and

$45.7125 x 45% (or .45) = $20.570625 which rounded up is $20.57

Step-by-step explanation:

Let $x be the price of an apple and $y be the price of an orange.

5x + 4y = 10

5x + 5y = 11

15([tex]\frac{458}{15}[/tex]+b) or

15(b+[tex]\frac{458}{15}[/tex])

Step-by-step explanation:

First we can subtract the 4.

458 + 15b

Now we need to find the GCF, but they do not share any kinds of factors together. This might look ugly, but it is what it is. We factor out 15 to get b by itself.

15([tex]\frac{458}{15}[/tex]+b) or

15(b+[tex]\frac{458}{15}[/tex])

Answer:

The quantities are not proportional.

Step-by-step explanation:

The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.

The graph represents two quantities are not proportional to each other.

A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.

Given:

As, A relationship is proportionate if its graph is a line or ray that passes through the origin.

and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.

Here the graph also does not pass through the origin.

Hence, the graph is not proportional.

Answer:

The correct answer is,

[tex]x = \frac{65}{37} [/tex]

Answer:

a₁₈ = 113

Step-by-step explanation:

There is a common difference d between consecutive terms

d = 49 - 45 = 53 - 49 = 57 - 53 = 4

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 45 and d = 4, then

a₁₈ = 45 + (17 × 4) = 45 + 68 = 113

Answer:

A solution to a linear equation means that the ordered pair is a point that lies on that line.

If someone were to say (2,5) is a solution to the equation y= 2x+3, you could check them by plugging in 2 where the variable "x" and seeing if y =5.

In this case,

y= 2(2)+3

y=7

(2,5) is not a solution.

Answer:

x<2/3b+-8/3

Step-by-step explanation:

Let's solve for x.

−3x+2b>8

Step 1: Add -2b to both sides.

2b−3x+−2b>8+−2b

−3x>−2b+8

Step 2: Divide both sides by -3.

-3x/-3>-2b+8/-3

x<2/3b+-8/3

Answer is : x<2/3b+-8/3

Answer:

3.5 miles

Step-by-step explanation:

Step one:

given data

Samuel runs around a 1-mile track in 10 minutes

Samuel's speed is

speed= distance/time

speed= 1/10= 0.1 miles per minute

Sophia runs around the same track in 10 minutes

Hence Sophia's speed is also = 0.1 miles per minute

Step two:

Given that the time is 35 minutes, and their speeds are 0.1 miles per minute, we can find the distance from

speed= distance/time

distance= speed*time

distance= 0.1*35

distance= 3.5 miles

Step-by-step explanation:

Answer:

a)  ( r+ s) (x)  = 3 x + 9

b)   ( r . s ) (x) =  2 x² + 13 x +20

c) ( r- s) (x)  = -1 -x

Step-by-step explanation:

Step(i):-

Given that r(x) = x +4 and s(x) =  2x + 5

a)   ( r+ s) (x)  = r(x) + s(x)

                    = x +4 + 2x +5

                   = 3 x + 9

    ( r+ s) (x)  = 3 x + 9

b)

    ( r . s ) (x)  = r(x) . s(x)

                    = (x+4) . ( 2x +5)

                   = x ( 2x +5) + 4( 2x +5)

                  = 2 x² + 5 x + 8 x +20

                 = 2 x² + 13 x +20

( r . s ) (x) =  2 x² + 13 x +20

c)

 ( r- s) (x)  = r(x) - s(x)

               =  (x+4 - ( 2x +5)

              = x +4 - 2x -5

            = -x -1

( r- s) (x)  = -1 -x

Step-by-step explanation:

Answer:

taking the square root of both sides of the equation

Step-by-step explanation:

The operation which is performed in the derivation of the quadratic formula moving from Step 6 to Step 7 is taking the square root of both sides of the equation.

Quadratic equations are polynomial equations of second degree.

The general form of a quadratic equation is ax² + b x + c = 0.

Given two steps in deriving the quadratic formula which is used to find the roots of a quadratic equation.

The first step is,

step 6 : (b² - 4ac) / (4a)² = (x + b / 2a)²

step 7 : ± √(b² - 4ac) / 2a = x + b / 2a

We have to find which step is done in between to transform from step 6 to step 7.

It is clear that square root is taken.

When the square root is taken in step 6,

±√[(b² - 4ac) / (4a)²] = √[(x + b / 2a)²]

√(b² - 4ac) / √(4a)² = √(x + b / 2a)²

± √(b² - 4ac) / 2a = x + b / 2a

Hence the step performed is taking the square root on both sides.
