Answer:

Step-by-step explanation:

Like terms are terms that have the same variable part.

The variable part of all three terms is u, so all terms are like terms.

5u + u - 6u =

= 5u + 1u 6u

= 6u - 6u

= 0

vfiekz [6]

Answer:

He sold 240 rolls.

Step-by-step explanation:

To find the amount of rolls he sold, we can multiply the amount of rolls in each box by the amount of boxes sold. If there are 6 rolls in each box, and he sold 40 boxes, then we would multiply 6 by 40.

6*40=240.

He sold 240 rolls.

Hope this helps!

Write an equation of a line that has a slope of 5 and goes through the point (-8, 35)?

MrRa [10]

Y = 5x + b
Plug in the point
35 = 5(-8) + b
35 = -40 + b, b = 75

A curve passes through the point (0, 5) and has the property that the slope of the curve at every point P is twice the y-coordin

Anit [1.1K]

Answer:

$y=5e^{2x}$

Step-by-step explanation:

Let (x,y) represents a point P on the curve,

So, the slope of the curve at point P = $\frac{dy}{dx}$

According to the question,

$\frac{dy}{dx}=2y$

$\frac{1}{y}dy=2dx$

Integrating both sides,

$\int \frac{dy}{y}=2dx$

$ln y=2x+ln C$

$ln y-ln C = 2x$

$ln(\frac{y}{C})=2x$

$\frac{y}{C}=e^{2x}$

$\implies y=Ce^{2x}$

Since, the curve is passing through the point (0, 5),

$5=Ce^{0}\implies C=5$

Hence, the required equation of the curve is,

$y=5e^{2x}$

According to the University of Nevada Center for Logistics Management, 6% of all merchandise sold in the United States gets retu

KatRina [158]

Answer: 0.1

Step-by-step explanation:

Given : A Houston department store sampled 80 items sold in January and found that 8 of the items were returned.

In other words, sample size : n=1040

Number of items returned : x= 8

Let p be the proportion of items returned for the population of sales transactions at the Houston store.

As per sample , the sample proportion of items returned for the population of sales transactions at the Houston store is :

$\hat{p}=\dfrac{x}{n}=\dfrac{8}{80}=0.1$

As we know that , the sample proportion is the best estimate of the population proportion.

Therefore,a point estimate of the proportion of items returned for the population of sales transactions at the Houston store is 0.1.
