Is y= x2-1 a linear equation

1 answer:

3 0

Answer: With the way you wrote it, I don't know. I'm assuming that it's $y=x^2+1$ . If that's the case, then no it's not linear.

Step-by-step explanation:

It's not a straight line. Graph it.

It's frustrating seeing questions like yours where the person asking literally does not even think through about their question. Next time, at least try the problem on your own instead of just deciding that you can't do it. This is an extremely easy problem, and I'm guessing you're just copying answers on here. The naivety here is palpable.

Given p ≠ q ≠ 0, what is the equation of the line that passes through the points (–p, –q) and (p, q)?

Hey :))

(-p,-q)(p,q)slope = (q - (-q) / (p - (-p) = (q + q) / (p + p) = 2q / 2p = q/p
y = mx + b.....slope(m) = q/p(p,q)...x = p and y = qnow we sub and find b, the y intq = (q/p)(p) + bq = q + bq - q = b0 = b
so ur equation is : y = (q/p)x + 0...or just y = (q/p)x....its answer B
HOPE THIS HELPED!!! :))

Correct Question: Find the simplified product: $\sqrt{2x^3}*\sqrt{18x^5}$

Answer:

$6x^4$

Step-by-step explanation:

Based on the rules of radicals, since $\sqrt{2x^3}$ and $\sqrt{18x^5}$ has the same index (square root), therefore:

$\sqrt{2x^3}*\sqrt{18x^5} = \sqrt{2x^3 * 18x^5}$

To simplify this, multiply their bases together, and add their exponents.

$= \sqrt{2*18x^{3+5}$

$= \sqrt{36x^{8}$

Simplify further

$= \sqrt{36}*\sqrt{x^8}$

$= \sqrt{6*6}*\sqrt{x^4*x^4}$

$= 6x^4$

If p q r is prime numbers such that pq+r=73, what is the least possible value of p+q+r

Jobisdone [24]

The answer to this question would be: p+q+r = 2 + 17 + 39= 58

In this question, p q r is a prime number. Most of the prime number is an odd number. If p q r all odd number, it wouldn't be possible to get 73 since
odd x odd + odd= odd + odd = even
Since 73 is an odd number, it is clear that one of the p q r needs to be an even number.

There is only one odd prime number which is 2. If you put 2 in the r the result would be:
pq+2= 73
pq= 71
There will be no solution for pq since 71 is prime number. That mean 2 must be either p or q. Let say that 2 is p, then the equation would be: 2q + r= 73

The least possible value of p+q+r would be achieved by founding the highest q since its coefficient is 2 times r. Maximum q would be 73/2= 36.5 so you can try backward from that. Since q= 31, q=29, q=23 and q=19 wouldn't result in a prime number r, the least result would be q=17
r= 73-2q
r= 73- 2(17)
r= 73-34=39

p+q+r = 2 + 17 + 39= 58
