Question 11 of 25

Mathematics
1 answer:
malfutka [58]3 years ago
4 0

Answer:

D

Step-by-step explanation:

simple : when we have a point defined as (1, 4), it means x = 1, y = 4.

and since the point is on the graph of a function/equation it means that when we use x = 1 and calculate the equation, we get 4 as result (= y). so yes, that means that both sides of the "=" sign are indeed equal for this pair of values, which makes the equation true.

but there will be usually many other pairs that do that too.

Answer:

original price $75

discount $18.75

sale price $56.25

Step-by-step explanation:

I found a pair of dress pants for $75.

Since the discount is 25%, then the discount is

25% of $75 = 0.25 × $75 = $18.75

The sale price is the original price, $75, minus the discount, $18.75.

$75 - $18.75 = $56.25

PLEASE HELP ME!!! 20 POINTS!!!
sukhopar [10]

Hello.

The answer is <em>D. It is reviewed and amended.  </em>The reason why is because the State Constitution(s) are usually longer than the regular Constitution, which has roughly 4,000 words. State Constitutions are normally 8,500 words or longer. So it takes a long time to amend because they are longer.

Please help me with this math question. Thank you.
Natasha2012 [34]

Answer:

D

Step-by-step explanation:

We want to find the values of <em>x</em> such that:

\displaystyle -x^2 + 7x + 5 = 0

We can use the quadratic formula. Recall that:
\displaystyle x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}

In this case, <em>a</em> = -1, <em>b</em> = 7, and <em>c</em> = 5. Substitute and evaluate:
\displaystyle \begin{aligned} x & = \frac{-(7)\pm\sqrt{(7)^2-4(-1)(5)}}{2(-1)}\\ \\  & = \frac{-7\pm\sqrt{49+20}}{-2} \\ \\  & = \frac{-7\pm\sqrt{69}}{-2}\end{aligned}

In conclusion, the answer is D.
