Answer:
iii) a=3b/2
Step-by-step explanation:
7a-2b= 5a+b
7a-5a=2b+b
2a=3b
a=3b/2
The answer would be 1
Slope formula is y2-y1/x2-x1
8-2/8-2
6/6
1
Answer:
Step-by-step explanation:
The side of the square = 3^2/7
Use the law of exponents . If the power is a fraction, that means it is
3^2/7 = 3^2 x 1/7 = 7√9
To find the area you multiply this by itself.
This gives you 1.87...
Hope this helps
These are 3 questions and 3 answers.1) Find
Answer: 4.Explanation:The expression means the
limit as the function f(x) approaches 2 from the right.Then, you have to use the function (the line) that comes from the right of 2 and gets as close as you want to x = 2.
That is the line that has the open circle around
y = 4, and that is the limit searched.
2) Use the graph to determine the limit if it exists.Answer: 

To determine each limit you
use the function from the side the value of x is being approached.Note, that since the two limits are different it is said that the limit of the function as it approaches 2 does not exist.
3)
Answer: - 1
To find the limit when the function is approached to 3 from the left you
follow the line that ends with the open circle at (3, -1).Therefore, the limit is - 1.
You have to get y by itself. Divide by 7 on both sides to get 1.43x-11=y. Hope this helps! ;)
