The answer to your question is: x=10. y=2
IrinaVladis [17]3 years ago

Answer:

(5,-1)

(10,2)

Step-by-step explanation:

we have

The ordered pairs that are solutions to the equation 3x-5y=20 are

(5,y),(x,2)

Step 1

Substitute the value of x of the first ordered pair and solve for y in the equation

3(5)-5y=20

5y=15-20

y=-1

The first ordered pair is (5,-1)

Step 2

Substitute the value of y of the second ordered pair and solve for x in the equation

3x-5(2)=20

3x=20+10

x=10

The second ordered pair is (10,2)

Which function grows the fastest for large values of x? f(x)=8x f(x)=3x f(x)=4x2+3 f(x)=1.5x 20 points
Aleonysh [2.5K]
The 4 functions are:
f_1 (x) = 8x
f_2(x)=3x
f_3(x)=4x^2+3
f_4(x)=1.5 x

Let's keep in mind that for large values of x, a quadratic function grows faster than a linear function:
ax^2 \ \textgreater \  kx for large values of x

In this problem, we can see that the only quadratic function is f_3(x), while all the others are linear functions, so the function that grows faster for large values of x is
f_3(x) = 4x^2 +3

Ilia_Sergeevich [38]

Hello,

First, you must understand that

(f-g)(x) means f(x)-g(x) it is the difference of two functions :

f(x)=2x+4 and g(x)=3x-7

f(5)=2*5+4=10+4=14

g(5)=3*5-7=15-7=8

So, (f-g)(5)= f(5)-g(5)=14-8<u>=6</u>

Answer A: none of the choices are correct.

An other way to do it:

(f-g)(x)=f(x)-g(x)=2x+4-(3x-7)= 2x-3x+4+7=-x+11

if x= 5 then (f-g)(5)=-5+11<u>=6</u>
