Determine if the following equation is an identity equation, a conditional equation, or an inconsistent equation. −4x−6x−23=−10−
1 answer:
The given equation is inconsistent equation.
Step-by-step explanation:
Lets define all three types of equations first
<u>Identity Equation:</u>
An equation is called identity equation when it is true for all values of variable involved.
<u>Conditional equation:</u>
Conditional equation is an equation which only true for some values.
<u>Inconsistent Equation:</u>
When the variable is unknown, the equation is called inconsistent equation.
The given equation is:
Solving the equation
In the given equation, the variable has become unknown so the given equation is an inconsistent equation

Answer:
is the same as
by co-function identities
Step-by-step explanation:
Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
- sin (90° – x) = cos x
- cos (90° – x) = sin x
This means that .
Answer:
Step-by-step explanation:
<u><em>The complete options are</em></u>
a) x - 2y = 30
b) 4x - 3y = 30
c) 3x - 4y = 30
d) 6x - 6y = 30
The given equation is
<u>Verify option d</u>
we have
Divide by 6 both sides
therefore
and
are equivalent
