Given:
The sum of two angles 5x and 50 degrees equals 90 degrees.
To find: The value of x
Explanation:
Since the sum of two given angles equals 90 degrees.
So, we can write it as,
Solving for x we get,
Thus, the value of x is 8.
Final answer: The value of x is 8.
Answer:
89
Step-by-step explanation:
To find the area of the rectangle, you do 13 times 8. That gives you 104. Now, for the triangle, you do 1/2 base times height. That is 1/2 of (13 - (4 + 4)) times 6. That equals 1/2 of 5 times 6. So 5 times 3 is 15. 104 - 15 is 89. I hope this helped and please mark me brainliest! Thanks.
Answer:
f(x) = (x +1)/(x -1)
Step-by-step explanation:
Let f(x) = y. We want to find y such that ...
g(y) = x
(y +1)/(y -1) = x
y +1 = xy -x . . . . . . multiply by y-1
y -xy = -x -1 . . . . . . add -1 -xy
y(x -1) = x +1 . . . . . . multiply by -1 and factor out y
y = (x +1)/(x -1) . . . . divide by the coefficient of y
Then ...
f(x) = (x +1)/(x -1)
_____
<em>Check</em>
g(f(x)) = ((x +1)/(x -1) +1)/((x +1)/(x -1) -1)
= ((x +1 +x -1)/(x -1)) / ((x +1 -x +1)/(x -1))
= 2x/2
= x
Answer:
The gradient of the graph below is 
Step-by-step explanation:
We need to calculate the gradient of the graph
The gradient of graph is actually slope of the graph.
The slope of graph can be calculated using formula: 
Taking any 2 points on graph i.e
(1,0) and (-1,-3)
We have 
Putting values and finding gradient:
So, The gradient of the graph below is
You are probably expected to choose ...
• All integers are rational numbers.
• Terminating decimals are rational numbers.
However, the premise of ...
• 0.278254….. is a terminating decimal, therefore it is a rational number.
is False, so the rules of logic allow any conclusion—meaning the implication is True. (As it happens, a repeating decimal is, in fact, a rational number.) So, this, too, is a true statement.
