What number si in the middle of 2.3 and 9.5

The x-value of the intersection point of the lines is ( d - b)/(a-c)

Intersection of lines

Given the equation of a line expressed as;

y = ax +b and;

y = cx + d.

Equating both lines, we will have:

• ax + b = cx + d

Make x the subject of the formula:

ax - cx = d = b

x (a-c) = d - b

x = ( d - b)/(a-c)

Hence the x-value of the intersection point of the lines is ( d - b)/(a-c)

The answer is given by the second choice: letter B. 14.75 is the answer because to get the mean, you should add all the numbers and then divide it by how many numbers there are. For example, in this case, you add 12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18 to each other. You will get the answer 172. After that, you should divide 172 by 12 because there are 12 numbers in the data set. 

Answer:

1)28

Step-by-step explanation:

The area of square=49m^2

or,L^2=49

i.e. L=7

also perimeter =4L

or, =4×7

or, perimeter=28m

Answer:

C. It has been stretched horizontally.

Step-by-step explanation:

According to the diagram, the parabola has not been reflected in any way, nor has it been translated, since the parabola is pointing up in a smile, and the vertex is still at the origin.

The parabola does appear to be stretched, since the parent function had points at (1, 1), and (2, 4), but this parabola does not contain those points.

Since the parabola appears to be flatter than the parent function, we can say that C. It has been stretched horizontally.

Hope this helps!
