Answer:
(4, 5 )
Step-by-step explanation:
x + y = 9 → (1)
x - y = - 1 → (2)
adding the 2 equations term by term will eliminate y
2x + 0 = 8
2x = 8 ( divide both sides by 2 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
substituting into (1)
4 + y = 9 ( subtract 4 from both sides )
y = 5
solution is (4, 5 )
Answer:
x=19
Step-by-step explanation:
24-5=19
Answer:
the inverse of the quadratic function
is 
Step-by-step explanation:
We need to find inverse of the quadratic function
Let

Replace x and y

Now, we will solve for y
Adding 3 on both sides


Taking square root on both sides

Now replace y with 

So, the inverse of the quadratic function
is 
Answer:
dont know sorry dude
Step-by-step explanation:
<u>Answer:</u>
The correct answer option is 21.
<u>Step-by-step explanation:</u>
We know that the given lines PW and AD intersect at the point C.
Therefore, the two given angles are equal to each other and we can write them in the form of an equation as:
(4x - 4)° = (3x + 17)°
Solving for x to get:
4x - 4 = 3x + 17
4x - 3x = 4 + 17
x = 21
Therefore, the value of x is equal to 21.
