The football team has a total of 50 jerseys. There are 30 medium sized jerseys. What percent of the jerseys are medium sized jer
german

60% are medium because you would have 30/50 which when you are doing percents,  percents are always out of 100 so you would multiply 50 and 30 by 2, therefore getting 60/100 and getting 60%

Fabiano and Sonali's teacher gave them a system of linear equations to solve. They each took a few steps that led to the systems
marin [14]
Question: Which system has the same solution as the teacher's system?

Systems of equations that have the same solution are called equivalent systems.We are given with a system of two equations, we can make an equivalent system by substituting one equation by the sum of the two equations.

Given System:
<span>
                                 8x-16y=14</span>→eq.1
                                 −x+5y=−3→eq.2<span>
Teacher's Solution:
From eq.2
x = 5y + 3
Substituting the value of x in eq.1
We get,
</span> 8(5y + 3) - 16y = 14
40y + 24 - 16y = 14
24y + 24 = 14
24y = 14-24
24y = -10
y = -10/24
y = -5/12

Substituting y-value in eq.2,
 −x+5(-5/12) = −3
-x -25/12 = -3
-x = -3 + 21/12
-x = 15/12
x = -5/4

<span>Fabiano:
</span>                                 3x−15y=<span>9
</span>                                 8x−16y=−<span>7

</span>Rearranging both equations:
y = 1/5x - 3/5
y = 1/2x+7/16

Placing both equations equal to each other,
1/5x - 3/5= 1/2x+7/16
1/5x -1/2x = 7/16 +3/5
-3/5x = 83/80
x = -83×5/80×3
x = -415/240
x = -83/48
This doesnt matches the teachers solution so we will move to sonali.

<span>Sonali
</span>                                 −x+5y=−<span>3
</span>                                 −4x+8y=−7
Rearranging both equations:
y = 1/5x - 3/5
y = 1/2x -7/8

Placing both equations equal to each other,
1/5x - 3/5 = 1/2x -7/8
1/5x -1/2x = -7/8 +3/5
-3/10x = -11/40
x = 110/120
x = 11/12

This doesn't match the teacher's solution either, so we will conclude that none of the solutions to the system of equation has the same answer as the teacher.

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
mr_godi [17]

Answer:

To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^-1(x)= ln(x+4)/2

Step-by-step explanation:

f(x) = e^2x - 4

to find the inverse let

y = e^2x - 4

Replace x and y

x = e^2y - 4

and now, solve to find value of y

x + 4 = e^2y

taking ln on both sides:

ln(x+4) = ln(e^2y)

ln(x+4) = 2y

=> y = ln(x+4)/2

=> f^-1(x)= ln(x+4)/2

So, To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^-1(x)= ln(x+4)/2
