For this, we have to look at ratios between the prices.
so, for A, its $350 for 100 copies
if we take 350/100, you get that one copy is $3.50

using this info, we can solve for 40 papers. 40*3.5 is 140, so it would actually cost 140 dollars for 40 papers

now B.
150/40 is $3.75, so one copy is 3.75
so 100 copies. that would be 3.75*100 which is 375 for 100 copies

What is the y coordinate in the solution for the system of linear equations below
Natali5045456 [20]

Answer:

y=6

Step-by-step explanation:

use elimination by making the ys opposite in value and eliminating them from the equation so there is only variable:

-3x+2y=6

2(4x-y=2)

-3x+2y=6

8x-2y=4

Combine like terms and divide by 5 on both sides.

5x=10

x=2

Plug x in to find y:

4(2)-y=2

8-y=2

y=6

Three people who work full-time are to work together on a project, but their total time on the project is to be equivalent to th
uranmaximum [27]

Answer:

  1/6

Step-by-step explanation:

Let x represent the proportion of time the third person spends on the project. You want ...

  1/2 + 1/3 + x = 1 . . . . full-time equivalents

  5/6 + x = 1 . . . . simplify

  x = 1/6 . . . . . . . subtract 5/6

The third person should budget 1/6 of their time to the project.

FinnZ [79.3K]

Keep your mom, you only have one. But anyway;

Use the Pythagorean Theorem: A^2 + B^2 = C^2

12^2 + 21^2 = C^2

144 + 441 = C^2

585 = C^2

square root of 585 = approximately 24.2

Select the correct answer. What is the range of the function f(x) = -4\x+ 11 - 5? A. (-4,-5) B. [-5,-) OC. (-4,-) OD. (-2,-4] Re
Y_Kistochka [10]

We are given the following function:

f(x)=-4\lvert x+1\rvert-5

This function is equivalent to the function:

g(x)=-4\lvert x+1\rvert

Together with a translation 5 units in the negative direction of the "x" axis. Since the range of g(x) is all the values of "y" that are smaller or equal to zero, if we translate 5 units in the negative direction of the y-axis the range is:

R(f(x))=\mleft\lbrace y\parallel y\mright?\le5\rbrace

or in interval notation:

R(f(x))=(-\infty,-5\rbrack
