Add 7 to both sides. 4x=36. 36/4 is 9. So x=9.
Answer: the slope is 2!
Step-by-step explanation:
Hello!
You can use the Pythagorean Theorem to solve this
c is the hypotenuse
a and b are the legs
Put in the values you know
Square the numbers
Subtract 2.25 from both sides
Take the square root of both sides
b = 0.8
The answer is 0.8km
Hope this helps!
If x is less than 81, then we get a solution, but x should also be larger than or equal to zero since radicands must be nonnegative, therefore, <span>x<81.
