Answer:
Choice B and Choise C.
Step-by-step explanation:
Equivalent expressions are those expressions that have the same value but they look different.
Given the following expression provided in the exercise:
You need to remember the multiplication of signs in order to find the equivalent expressions:
Then:
- Eliminating the parentheses, you get this equivalent expression:
- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:
This is an equivalent expression to
5t=45
45/5=9
The answer is C

No you type the numbers press = and poof
Answer:
x = 2/5 and y =1 (2/5, 1)
Step-by-step explanation:
I will assume that you meant y = -5x + 3. If that's the case, then we equate
y = -5x + 3 to y = 1, obtaining:
-5x = -2, so that x = 2/5 and y =1.
Answer:
is used to prove the given equation.
Step-by-step explanation:
We have given an equation:
We will consider right hand side first
tan x can be written as:
So, on substituting tan x in the left hand side of the given equation we get:
Cancel common term from denominator and numerator which is cosx we get
And we have an identity:
Hence, right hand side is equal to .
