The value of x in 6x+7=3x+16

kozerog [31]

Answer:

x=3

Step-by-step explanation:

6x+7=3x+16

Subtract 3x from each side

6x-3x+7=3x-3x+16

3x+7 = 16

Subtract 7 from each side

3x+7-7 = 16-7

3x =9

Divide each side by 3

3x/3 = 9/3

x =3

Let's derive the equations for the two graphs;

For the graph towards the right,

The slope = y2-y1/x2-x1; so we choose two corresponding points (x1,y1); (x2,y2)

Let's choose points;

(2,1) and (3,2)

The slope = 2-1/ 3-2 = 1/1 = 1

From the general equation of a line

y = mx + c = 1× x + (-1) = x-1

y = x-1

Similarly for that towards the left we have;

The slope = y2-y1/x2-x1; so we choose two corresponding points (x1,y1); (x2,y2)

Let's choose points;

(2,1) and (3,2)

The slope = 2-1/ 3-2 = 1/1 = 1

From the general equation of a line

y = mx + c = 1× x + (-1) = x-1

y = x-1

Similarly for that towards the left we have;

The slope = y2-y1/x2-x1; so we choose two corresponding points (x1,y1); (x2,y2)

Let's choose points;

(-7,0) and (-4,-3)

Slope = -3-0/ -4-(-7) = -3/ 3 = -1

From the general equation of a line

y = mx + c = -1× x + c = -x + c

Since c is not obvious we can find the equation by picking just a point along the graph along side an arbitrary (x,y) point hence we have for slope;

If we pick (-7,0)

y-0 / x-(-7) = -1

y / x+7 = -1

y = -x -7

The equations of the graphed lines are;

y=x-1

y=-x-7

Look at option D you we see it's the same as the equation of the graph towards the right y=x-1

For the records

y=[x+3]-4 = x+3-4 = x-1

Alan has an annual base salary of $18,000. In addition to his salary, he earns 9% of his total sales (S). If he wants to earn at

aivan3 [116]

The right answer is Option D: S>$300,000.

Step-by-step explanation:

Given,

Base salary of Alan = $18000

Commission = 9% = $\frac{9}{100} = 0.09$

Amount Alan wants to earn = $45000 or more

Let,

s be the worth he needs to sell.

Therefore,

Base salary + Commission*Total sales>Amount Alan wants to earn

18000+0.09s>45000

$0.09s>45000-18000\\0.09s>27000$

Dividing both sides by 0.09

$\frac{0.09s}{0.09}>\frac{27000}{0.09}\\s>300000$

Alan must sold items that worth at least $300,000.

The right answer is Option D: S>$300,000.
