150mi/3hrs = 50mph
400/50 = 8 hours
Check:
8hours * 50mi = 400 miles traveled
I think the answer is 4/8,btw I'm not too sure about the answer
Answer:
x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3
Step-by-step explanation:
Solve for x over the real numbers:
(9 x - 4)^2 = 18
Take the square root of both sides:
9 x - 4 = 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)
Add 4 to both sides:
9 x = 4 + 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)
Divide both sides by 9:
x = 4/9 + sqrt(2)/3 or 9 x - 4 = -3 sqrt(2)
Add 4 to both sides:
x = 4/9 + sqrt(2)/3 or 9 x = 4 - 3 sqrt(2)
Divide both sides by 9:
Answer: x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3
Answer:
15 + x = 38

a number = put any random letter, or my choice is just using "x" so its just means a varaible
HOPE THIS HELPED!!!!! :D
x-intercept is (2,0)
y-intercept is (0,-5)
Step-by-step explanation:
Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.
Finding x-intercept
X-intercept: Substitute 0 for y and then solve for x. Write your answer in the form (__, 0)
Putting y=0

So, x-intercept is (2,0)
Finding y-intercept
Y-intercept: Substitute 0 for x and then solve for y. Write your answer in the form (0, __)
Putting x=0

So, y-intercept is (0,-5)
