Answer:

slope= 3/5  y int=-2 equation y = 3/5 -2

Step-by-step explanation:

slope= rise over run

y int = where the y axis and the line meet

equation= y =mx+b

m=slope

b = y int

A rectangle with an area of 5/8 ft² is dilated by a factor of 8. What is the area of the dilated rectangle?
galben [10]
A dilation is basically a factor of enlargement or reduction, where you multiply the factor for the dilation. 

So,

Multiply the numerator 5 by the factor of 8. 

5*8= 40 

40/8 ft^2= 5 ft^2

The new area if 5 ft^2. 

I hope this helps!

Evaluate the limit 9n^3 + 5n - 2/2n^3
VikaD [51]

Answer:

9/2    if  n goes to infinity  and that the 2n^3 is under the whole expression

Step-by-step explanation:

Let me clear this .

find  limit  (9n^3  + 5*n  - 2)/ (2n^3)

as n --> infinity

Did I put the parentheses in the right spot?

because if you leave it the way you did, then the whole expression goes to positive infinity as n goes to infinity  But I will do this with parentheses

so

find  limit  (9n^3  + 5*n  - 2)/ (2n^3)

simplify expression

limit   (9/2)  +   5/(2n^2)   -   1/(n^3)

=  (9/2)  + 0  - 0

=  (9/2)

Right the slope intercept form for the line that travels through (4,-1) and is parallel to y=1/4x
ololo11 [35]

Answer:

Step-by-step explanation:

The slope is given to you by the line y = 1/4 x

The slope is just read as the number in front of x providing that the coefficient of y is 1. If that is not so, then you must divide by the coefficient in front of y. So far what you have is y = 1/4 x + b.

The second part of the question is to use the given point to find b.

x = 4

y = -1

b = ?                       substitute x and y to find b

y = 1/4 * 4 + b

- 1 = 1/4 * 4 + b

-1 = 1 + b

-2 = b

The equation of the line is y = 1/4 x - 2 Just to confirm this, I'm going to include the graph with the point 4,-1 on it.

Forty five men can construct a road 210m long in 60 days. What length would be constructed by 72 men in 50 days assuming that al
blagie [28]

Answer:

280m

Step-by-step explanation:

Work rate would be (210m)/(45people)(60days)=7/90 m/(people)(day)

7/90 m/(people)(day) * 72people * 50days =280m
