Which system has the same situation below?
Likurg_2 [28]

Answer:

2

Step-by-step explanation:

Let's solve the given system of equations.

<u>Given system</u>

x +3y= 10 ----(1)

-2x -2y= 4 ----(2)

From (2):

-2(x +y)= 4

Dividing both sides by -2:

x +y= -2 ----(2)

Thus, options 3 and 4 are incorrect as x +y≠ -2.

(1) -(2):

(x +3y) -(x +y)= 10 -(-2)

Expand:

x +3y -x -y= 10 +2

2y= 12

Divide both sides by 2:

y= 12 ÷2

y= 6

Substitute y= 6 into (2):

x +6= -2

x= -6 -2

x= -8

Options (1) and (2) differs only by the value of the expression of -x +y. Thus, let's find its value in the given system of equations.

-x +y

= -(-8) +6

= 8 +6

= 14

Thus, option 2 is the correct option.

Find the average rate of change of an exponential function f (x) over the interval 1 ≤ x ≤ 3.
Neko [114]

Answer:

Option b. 12

Step-by-step explanation:

we know that

To find the average rate of change, we divide the change in the output value by the change in the input value

The average rate of change is equal to

\frac{f(b)-f(a)}{b-a}

In this problem we have

a=1

b=3

f(a)=f(1)=1  

f(b)=f(3)=25

Substitute

\frac{25-1}{3-1}=12
