Answer:
Step-by-step explanation:
The picture of the question in the attached figure
step 1
In the right triangle ABD
Applying the Pythagorean Theorem
----> equation A
step 2
In the right triangle BDC
Applying the Pythagorean Theorem
----> equation B
step 3
In the right triangle ABC
Applying the Pythagorean Theorem
----> equation C
step 4
Equate equation A and equation B
-----> equation D
step 5
substitute equation D in equation C
solve for z
simplify
Find the value of x
Find the value of y
You can use substitution or elimination method to solve. <em>I used substitution.</em>
2(1/2y + 5) + 3y = -14
y + 10 + 3y = -14
4y + 10 = -14
4y = -24
y = -6
x = 1/2y + 5 = 1/2(-6) + 5 = -3 + 5 = 2
x = 2, y = -6
Answer: A
Answer:
65.8%
Step-by-step explanation:
94.3x100/143.3=65.8
We can see this is a line, so it is a linear function.
Linear function always have constant slope, or constant rate of change.
So the answer is A.
It means you multiply 6.2 x 0.48
which equals = 2.976
( ) mean multiply
