Answer:

Step-by-step explanation:
Given that,

We need to find the value of cos x.
We know that,

Using the above relation,

So, the value of cos x is equal to
.
X=6 because 2*6=12 and 12+4=16
the point where the two lines intersect will be your answer.
from the photo, your x-coordinate will be 4, and your y-coordinate will be 1. that's where the two lines meet, so that's the solution.
the answer will be (4,1).
i hope i helped! good luck.
Y=X/5
Step-by-step explanation:
Step 1:
Let X be the input and Y be the output variable
Given: the output is one-fifth of the input
Step 2:
Y=X/5 be the require function
Eq:
for X=1, Y = 1/5
X=2, Y=2/5, etc
Answer:
Equation: x + 16 + 13 + x = 21 ; x = -4
Step-by-step explanation:
x + 16 + 13 + x = 21 (Given)
2x + 29 = 21 (Added like terms)
2x = -8 (Subtracted 29 on both sides)
x = -4 (Divided 2 on both sides)
