Answer:

Amir is wrong

Step-by-step explanation:

The function y = x² + 16 is positive for any value of x, hence the graph has no intersection with the x-axis and therefore has no real zero's.

If no zero's, -4 also can't be its zero.

Answer:

Step-by-step explanation:

It's law of equations .The number of zeros is also equal to the highest degree of the polynomial/equation.

y=x^2+16 has 3 zeros
2 is for x and 1 is for y .

Hence 4 can't be a zero because it won't intercept the x axis.

Let's check

$\\ \sf\longmapsto (-4)^2+16=16+16=32\neq 0$

Answer:

$\frac{A}{1 + rt}$

Step-by-step explanation:

$a = p + prt$

Distributive property:

$A = P(1 + rt)$

The divide both sides by $( 1 + rt)$ :

$\frac{A}{1 + rt}$

Which point lies on the line defined by 2x – y = 7?

Eduardwww [97]

So lets just assume that y = 1 since 2x is most likely an even number.
Then we can say that 2x = 8
8 divided by 2 is 4
so a point on this line could be (4,1)
Hope this helped

PLEASE ANSWER FAST WILL DO BRAINLIESTThe coordinate grid shows points A through K. What point is a solution to the system of ine

Alja [10]

Answer: points B (4,7) and I (9,3)

If the inequalities are

y > −2x + 10 and y> (½)x -2

Step-by-step explanation: If I interpreted the inequalities correctly, the attached graph shows them. It is possible that you meant y > 1/(2x-2) for the second inequality. If so, we start over!

You can test the values for all the points, but it appears that (4,7) and (9,3) both work.

The other coordinates appear to be outside the solution -- the dark-shaded area.

I hope this is your Brainliest answer. It was a lot of work!
