Choose the constant term that completes the perfect square trinomial.<br><br> y2 + y
Oduvanchick [21]

Hello!

First off, please write y2 + y as y^2 + y. The " ^ " symbol denotes exponentiation, whereas y2 is meaningless.

To find the constant term in question, take half of the coefficient of y (that is, take 1/2) and square it. Then we have y2 + y + 1/4.

The constant term in question is 1/4.

Which inequality is equivalent to -m ≥ 15?
Vera_Pavlovna [14]

Answer:

m ≤ -15

Step-by-step explanation:

You can convert m into positive by multiplying -1 on both sides of the equation. This would also result to a -15.

Note that when an unknown variable changes its sign, the symbol becomes the opposite version of itself.

So,

-m ≥ 15

-m(-1) ≥ 15(-1)

m ≤ -15

Complete the square for a circle. For #42.
makkiz [27]

we are given

2x^2+2y^2-28x+20y+20=0

we can see that

each terms are multiple of 2

so, we can factor out 2

2(x^2+y^2-14x+10y+10)=0

we can divide both sides by 2

x^2+y^2-14x+10y+10=0

we can rearrange it

x^2+-14x+y^2+10y+10=0

now, we can move 10 on right side

x^2+-14x+y^2+10y=-10

x^2+-2*7*x+y^2+2*5*y=-10

now, we can add both sides 7^2 and 5^2

x^2+-2*7*x+7^2+y^2+2*5*y+5^2=-10+7^2+5^2

(x-7)^2+(y+5)^2=-10+7^2+5^2

we can simplify it

(x-7)^2+(y+5)^2=64

we can also write as

(x-7)^2+(y+5)^2=8^2..............Answer
