Answer:

Step-by-step explanation:

\frac{\sqrt{x}+1 }{x-\sqrt{x}+1 }=\frac{\sqrt{x}+1}{(x+1)-\sqrt{x}}\\\\=\frac{(\sqrt{x}+1)([x+1]+\sqrt{x})}{([x+1]-\sqrt{x})+([x+1)+\sqrt{x}])}\\\\=\frac{\sqrt{x}*x+\sqrt{x}*1+\sqrt{x}*\sqrt{x}+1*x+1*1+1*\sqrt{x}}{(x+1)^{2}-(\sqrt{x})^{2}}\\\\\\=\frac{x\sqrt{x}+\sqrt{x}+x+1+x+\sqrt{x}}{x^{2}+2x+1-x}\\\\=\frac{x\sqrt{x}+2\sqrt{x}+2x+1}{x^{2}+x+1}\\\\

Can someone help me please
Sunny_sXe [5.5K]

Answer:

y = 2/3x +4

Step-by-step explanation:

The y intercept is where the line crosses the y axis

y intercept =4

We can find the slope using two points on the line

(0,4) and (3,6)

m = (y2-y1)/(x2-x1)

   = (6-4)/(3-0)

   = 2/3

The equation of a line in slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2/3x +4

Your weekly base salary is $150. You earn $20 for each phone you taht you sell. The company policy is that as a part-time employ
Eduardwww [97]

Answer:

You can sell at least 40 phones each week.

Step-by-step explanation:

Given that:

Weekly base salary = $150

Earning on each phone = $20

Maximum amount that can be earned each week = $950

Let,

m be the number of phones.

20m + 150 ≤ 950

20m ≤ 950 - 150

20m ≤ 800

Dividing both sides by 20

\frac{20m}{20}\leq \frac{800}{20}

m ≤ 40

Hence,

You can sell at least 40 phones each week.
