Expanding using the distributive property, we get (x-5)*(x-5)=x^2-5x-5x+25=x^2-10x+25. Multiplying that by -6, we get -6x^2+60x-150 . We then add 12 at the end to get -6x^2+60x-138. Using the quadratic formula (since we want the function to equal 0 to find the zeros), we get x=(-60+-sqrt(3600-3312))/(-6*2)=(-60+-sqrt(288))/-12. For sqrt(288), since 12^2=144 and 144*2=288, we can rewrite it as 12*sqrt(2). Putting that back in, we get
(-60+-(12*sqrt(2))/-12. Factoring it out, we get -5+-sqrt(2)=-5+sqrt(2) or -5-sqrt(2) which is C

Which equation is y = –3x2 – 12x – 2 rewritten in vertex form?
Andrej [43]
<span>The general equation of a quadratic is expressed as y = ax^2+bx+c. To convert the general equation to vertex form, we need to obtain this form:

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

This could be done by using completing the square method.

</span><span>y = –3x^2 – 12x – 2
</span><span>y + 2 = –3(x^2 + 4x) 
</span>y + 2 -12 <span>= –3(x^2 + 4x + 4) 
</span>y - 10 = -3(x+2)^2

Therefore, the answer is the first option.

What is the value of the negative zero of the function, f, defined by<br> f(x) = x^2 - 16
Lelu [443]

Answer:

x = -4

Step-by-step explanation:

f(x) = x² - 16

This is the difference of squares

which factors as

f(x) = (x - 4)(x + 4)

Therefor the negative zero is

Answer:

  P(0, 4), Q(-3, 0)

Step-by-step explanation:

To find the y-coordinate of P, replace x with 0 and solve for y:

  3y = 12

  y = 4 . . . . . divide by 3

__

To find the x-coordinate of Q, replace y with 0 and solve for x:

  -4x = 12

  x = -3 . . . . . divide by -4

Then the intercepts are P(0, 4) and Q(-3, 0). The line is drawn through those points for the indicated values of x.

Please help!!!!!!!!!!​
Troyanec [42]

Answer:

Step-by-step explanation:

p + n + d + q = 25

Put everything into quarters.

p and q are equally likely to be drawn

q + n + d + q = 25

There are 3 times as many nickels as quarters

n = 3q

q + 3q + d + q = 25

There is 25% more dimes than quarters.

d = 1.25 q

q + 3q + 1.25q + q = 25

6.25 q = 25

q = 25/6,25

=====================

q = 4

p = 4

d = 1.25 * 4 = 5

n = 12
