Answer:

1.) a = r / x - b

2.) x = - 14

Step-by-step explanation:

1.) r = x ( a + b )

r / x = x / x ( a + b) ...( Divide each side by x )

r / x = a + b

r / x - b = a + b - b ... ( Subtracting each side by b) r / x - b = a

2.) x / 2 = -7

x / 2 × 2 = -7 × 2 .. ( multiplying each side by 2 )

x = - 14

Answer:

a = (r/x) -b

x = -14

Step-by-step explanation:

r=x(a+b)

Divide each side by x

r/x = a+b

Subtract b

r/x  -b = a

x/2=-7

Multiply each side by 2

x/2*2 = -7*2

x = -14

An electrician charges a set fee for every house call and then charges an hourly ratedepending on how long the job takes. The to
Luda [366]

We have the equation:

C(t)=65+60t

Given the slope-intercept formula for the equation of the line, we have the following:

\begin{gathered} y=mx+b \\ m\colon\text{ slope} \\ If\text{ C=65+60t} \\ \Rightarrow slope\text{ = 60} \end{gathered}

Now, since we have that t is the number of hours the electrician spends working, the slope of the function represents the hourly rate charged.

When you look at the two cylinders with these values of r and h, what do you notice about the proportions of the cylinders?
Elden [556K]

Answer and Explanation:

Volume of a cylinder is given by

V= Pi*r²*h

where v= volume of the cylinder

Pi is constant = 22/7 or 3.14159

r= radius of the circle of the cylinder

h= height of the cylinder

If two cylinders are measured proportionally to the other based on radius and height of each cylinder, we look at the proportional equality of the ratio of the radius and height of one cylinder to the other. If one cylinder for example has ratio of radius and height =2/4 then it is proportional to the other cylinder with ratio 1/2

A manager finds a moderate negative correlation between the number of computer sales and the number of microwave sales in his st
BabaBlast [244]

Answer:

C) The correlation is most likely a coincidence.

Step-by-step explanation:

By general comprehension of the population and their buying habits, I don't think we can really establish a relation between the sales of computers and the microwaves in a general manner.  If the store is located near a university residence and it's September, there might be a link to be done, but in general, no.

It's not like some enters a store and says "Ok, will I buy a microwave or a computer today?".  Those are two totally different products, with different clienteles and different needs.
