Rate of change is also another name for the slope so in this case, the question is asking you for the slope.

How can we find the slope?
The formula for slope is y2-y1/x2-x1

Now let's plug in for the year 1980 and 1990.

239-120/1990-1980
= 119/10

Slope is 119/10.

A number is increased by 11 is multiplied by 2 the answer is 26 ​
nordsb [41]

Answer:

Number = 2

Step-by-step explanation:

Let the number be <em>x</em>.

According to the question,

  • Number increased by 11 = x+11
  • Multiplied by 2 is 26 : (x+11)*2 = 26

Equation will be,

  • 2(x+11) = 26

Solving for x,

  • 2x+22 = 26
  • 2x = 26-22
  • 2x = 4
  • x = 4/2
  • x = 2

Thus,the number is 2.
