If it takes 90 minutes to wait in line to purchase 12 eggs, how many eggs could you purchase if you waited 120 minutes?
AlekseyPX

Answer:

16 eggs

Step-by-step explanation:

we know that

it takes 90 minutes to wait in line to purchase 12 eggs

so

using proportion

Find out how many eggs could you purchase if you waited 120 minutes

\frac{90\ min}{12\ eggs}=\frac{120\ min}{x\ eggs}\\\\x=12(120)/90\\\\x= 16\ eggs

The legs of an isosceles triangle measure ( 2 x^4 + 2 x − 1 ) units each. The perimeter of the triangle is ( 5 x^4 − 2 x^3 + x −
nirvana33 [79]

Answer:

The base is x^4 -2x^3 -3x-1

Step-by-step explanation:

We know the perimeter of a triangle is the sum of the three sides

P = s1+s2+s3

We know the perimeter is  5 x^4 − 2 x^3 + x − 3

and two of the legs are 2 x^4 + 2 x − 1  since it is an isosceles triangle

P = 2s1 + s3

Subtract 2s1 from each side

P-2s1 =2s1 +s3 -2S1

P -2s1 =s3

Substituting what we know

5 x^4 − 2 x^3 + x − 3 - 2(2 x^4 + 2 x − 1) = s3

Distribute the -2

5 x^4 − 2 x^3 + x − 3 - 4 x^4 -4 x + 2 = s3

Combine like terms

5 x^4-4x^4 − 2 x^3 + x  -4 x -3+ 2 = s3

x^4 -2x^3 -3x-1 =s3

The base is x^4 -2x^3 -3x-1

What is the equation of a vertical line passing through the point (-5,-1)
Stels [109]
Learn this :
VUX -- vertical line, undefined slope, represented by x = a number
HOY -- horizontal line, 0 slope, represented by y = a number

ok....so u need the equation for a vertical line passing thru (-5,-1)...
a vertical line is represented by x = a number.....and that number will be the x value of ur points.

Therefore, ur equation is : x = -5 <==

**just so u know, if u were needing a horizontal line going thru the same points, ...and a horizontal line is represented by y = a number...with the number being the y value of ur points....the equation would be y = -1
