Is y=1/2x-1 proportional

Mathematics

1 answer:

Ber [7]2 years ago

Answer: No

Step-by-step explanation: Since y=2x+1 does not pass through the origin (i.e. there exists the constant term of 1 ), the variables y and x are not directly proportional - though, they do have a linear relationship.

Simplify 81^5=3^w and find w

Allisa [31]

Answer:

$w = 20$

Step-by-step explanation:

<u>Step 1: Find common bases</u>

$81^5 = 3^w$

$81$ → $3 * 3 * 3 * 3$ → $3^4$

Therefore, $81 = 3^4$

$81^5$ → $3^(^4^)^*^5$ → $3^2^0$

So... $3^2^0 = 3^w$

Since same base now, we can evaluate the exponents by themselves.

$20 = w$

Answer: $w = 20$

On the graph of the equation X-4Y= -16 what is the value of the Y-intercept?

Nonamiya [84]

we can always find the x-intercept by simply settting y = 0, and solving for "x".

and we can always find the y-intercept by simply setting x = 0 and solving for "y".

$\bf x-4y=-16\implies \stackrel{x=0}{0-4y=-16}\implies y=\cfrac{-16}{-4}\implies y=4

2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

2/1x2/5=4/5

now

2/1x-1/5=-2/5

now we do division

4/5/-2/5 we get -2

-2
