Answer:
x = 14.25
Step-by-step explanation:
Start with a^2 + b^2 = c^2
a = 11
b = x
c = 18
plug in and solve
11^2 + x^2 = 18^2
121 + x^2 = 324 - Simplify
x^2 = 203 - subtract 121 from both sides
x = 14.247 rounds to 14.25 - square root on both sides
QUESTION 1
The point C(3.6, -0.4) divides AB in the ratio 3 : 2.
The coordinates of A are (-6, 5).
Let the coordinates of B be 
We use the formula:
to determine the x-coordinate of B.
We substitute the known values to obtain:
This implies that:
We also use the formula:
to find the y-coordinate.
The coordinates of B are (10,-4)
QUESTION 2.
If point D divides CD in the ratio 4 : 5.
Then the coordinates of D are:
The coordinates of D are 
Answer: They are equivalent, and x = -4/7
Step-by-step explanation:
Fist we need to see what the answers to each of these equations are
7 + 5x = 3 - 2x
Subtract 7 on each side
5x = -4 - 2x
Add 2x
7x = -4
X = -4/7
Now the second one
7 + 7x = 3
Subtract 7
7x = -4
X = - 4/7
They are equal and x = -4/7
Answer:
y = 14
Step-by-step explanation:
Given x plug in 3 for x
y = (2times3) + 8
y = 6 + 8
to cheak ur awsner plug in y as 18 and solve for x
