Answer:
m = 1 and b = 5/7
Step-by-step explanation:
Take two of the points. The first two. (7, 5) and (8, 6).
We can find the slope using:
y2-y1/x2-x1
We can sub in the values:
6-5/8-7 = 1/1 = 1
So the slope is 1
now, putting this into y=mx+b, and using one of the coordinates from earlier, we can solve for b:
5 = (1)(7) + b
b = 5/7
Therefore, m = 1 and b = 5/7
Hope this helps!
Answer:
y = 1
Step-by-step explanation:
Answer:
c = 1
Step-by-step explanation:
we have -1/6 + 7/6
since 6 is a common denominator we can do
The expanded form of 9,540,000 is:
9,540,000 = 9000,000 + 500000 + 40000 + 000 +00 + 0
we can also write it as :
9,540,000 = 9 x 1000000 + 5 x 100000 + 4 x 10000
and using exponents as power of 10 is:
9,540,000 = 9 x 10⁶ + 5 x 10⁵ + 4 x 10⁴
Answer:
x = 5/2 + sqrt(41)/2 or x = 5/2 - sqrt(41)/2 thus 2 is the Answer
Step-by-step explanation:
Solve for x:
x^2 - 5 x - 4 = 0
Add 4 to both sides:
x^2 - 5 x = 4
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 41/4
Write the left hand side as a square:
(x - 5/2)^2 = 41/4
Take the square root of both sides:
x - 5/2 = sqrt(41)/2 or x - 5/2 = -sqrt(41)/2
Add 5/2 to both sides:
x = 5/2 + sqrt(41)/2 or x - 5/2 = -sqrt(41)/2
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(41)/2 or x = 5/2 - sqrt(41)/2
