Answer:
u = 7
Step-by-step explanation:
Using the slope intercept formula:
Substitute our values from the points and the known slope:
Now we multiply both sides by (8 - u) to isolate the x:
(8-u) x 
= -7 (8 - u)
Next we add 56 to both sides:
-7 = -56 + 7u
Finish off by dividing both sides by 7:
7u = 49
u = 7
If John has $0.75 and he needs $2.50, then you will subtract $0.75 from $2.50 to find out how much he needs which is $1.75. Hope I helped! Don't forget to help me with the Brainliest Answer! :D
Answer:
Option A
Step-by-step explanation:
Domain should be greater than/equal to 1 for the function to be one-one.
f has vertex at (1,0)
f inverse has (0,1)
f(x) = 4
(x - 1)⁴ = 4
x = 2.414
On f: (2.414, 4)
On f inverse: (4, 2.414)
Answer:
x=69.41860973
Step-by-step explanation:
We can use the law of sines
sin x sin 55
------------- = -----------
4 3.5
Using cross products
3.5 sin x = 4 sin 55
Divide each side by 3.5
sin x = 4/3.5 sin 55
Take the inverse sin of each side
x = sin ^-1 ( 4/3.5 sin 55)
x=69.41860973
