Step-by-step explanation:
<u>Step 1: Define</u>
x/5 - 1 = 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1 to both sides: x/5 = 11
- Multiply 5 on both sides: x = 55
There are infinite solutions because the x's cancel. When they do, 25 = 25. Thus, infinite.
This question is ambiguous because we don’t know if the two numbers are -4x^4 and -8x^3 or (-4x)^4 and (-8x)^3. In the first case 4x^3 is present in both and nothing else is. In the second case (4x)^3 is the largest common factor.

The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
