Which of the following is a solution of y - x > -3 (6, 2) (2, 6) (2, -1)

1 answer:

4 0

The correct point will make the inequality y-x>-3 "true." Look at each of the 3 given points separately. Subst. its coordinates into y-x>-3 and determine whether the resulting inequality is true or not. Is 2-6>-3? Is -4>-3? No. So, (6,2) is NOT a solution. Continue by checking out the other two points in the same manner.

What is the equation of the circle with center (-6,7) that passes through the point (4,-2). A. (x+6)^2+(y-7)^2=181 B. (x-6)^2+(y

pychu [463]

The equation of a cricle passing through (h,h) and with radius r is
$(x-h)^2+(y-k)^2=r^2$
so

cente ris (-6,7) and passing through (4,-2)
$(x-(-6))^2+(y-7)^2=r^2$
$(x+6)^2+(y-7)^2=r^2$
subsitute (4,-2) to find r^2

$(4+6)^2+(-2-7)^2=r^2$
$(10)^2+(-9)^2=r^2$
$100+81=r^2$
$181=r^2$

so it is

$(x+6)^2+(y-7)^2=181$
A is the answer

I am thinking of a number. i will add four and then multiply it by five. the answer will be thirty five. whats the number?

kodGreya [7K]

Answer:

B. 3

Step-by-step explanation:

Let's make an equation for this. Our unknown number is x.

We are adding 4.

x + 4

Then multiplying by 5.

(x + 4) • 5

It will equal 35.

(x + 4) • 5 = 35

To solve this, divide both sides by 5.

(x + 4) = 7

Now subtract 4 from both sides.

x = 3

This is your answer.

Check this by plugging it back into our original equation.

(x + 4) • 5 = 35

(3 + 4) • 5 = 35

7 • 5 = 35

35 = 35

Your answer is correct.

Hope this helps!

Find the vertex I’d this parabola y=-2x^2-4x+4

mamaluj [8]

Answer:

(-1, 6)

Step-by-step explanation:

A graphing calculator shows the vertex to be (x, y) = (-1, 6).

You can also find it by putting the equation into vertex form.

y = -2(x^2 +2x) +4

y = -2(x^2 +2x +1) +4 +2(1) . . . . . add 1 inside parens; the opposite outside

y = -2(x +1)^2 +6

Compare to ...

y = a(x -h)^2 +k

and you see a=-2, h=-1, k=6

The vertex is (h, k) = (-1, 6).
