Step-by-step explanation:
Start with the parentheses
Answer:
i am sorry i cant see the picture
Step-by-step explanation:
So, if the legs are a and b and the hypothuse is c then
a²+b²=c²
the distance bewteen the points is the hyptohuse
the legs are the distances between th x and y values
so
(7,11) and (-1,5)
distances between the x values are 1 leg
that is from 7 and -1, a distance of 8 units
distances betweeen the y values are the other leg
that is from 11 to 5
that is 6 units
a²+b²=c²
8²+6²=c²
64+36=c²
100=c²
sqrt both sides
10=c
the distance between them is 10 units
The sum of x and 9 divided by 2 is equal to 3x
(x + 9)/2 = 3x
Note the equal sign, what you do to one side, you do to the other. First, multiply 2 to both sides
(x + 9)/2(2) = 3x(2)
x + 9 = 6x
Subtract x from both sides
x (-x) + 9 = 6x(-x)
9 = 5x
Isolate the x. Divide 5 from both sides
9/5 = 5x/5
x = 9/5
9/5 is your answer for x
hope this helps
