<span>Reflexive Property of Equality</span>

Naddika [18.5K]3 years ago

5 0

It's the reflexive property because it's just relating it to itself (def. of reflexive)

As we all know: A=A, B=B, mx=mx, nothing changes.

So the answer is D

Answer:

The correct answer would be $a=\sqrt{c^2-b^2}$

Step-by-step explanation:

given $a^2+b^2=c^2$ we want to solve for a

How?

We can do this by using basic algebra ( isolating the variable (a ))

Step 1 subtract $b^2$ from each side

$a^2+b^2-b^2=a^2\\c^2-b^2=c^2-b^2$

now we have $a^2=c^2-b^2$

step 2 take the square root of each side

$\sqrt{a^2} =a\\\sqrt{c^2-b^2} =\sqrt{c^2-b^2}$

we're left with $a=\sqrt{c^2-b^2}$

Hence your answer is A

Answer:

y-intercept is 30

Step-by-step explanation:

Given the model $y = 10x + 30.$ comparing this model to the equation of a straight lines we can get the y- intercept

$y = 10x + 30\\\y= mx+c$

The y- intercept is 30 which is the constant factor and it describes to us about the one-time registration fee of $30.
