What is the vertex form of 4x^2+4x-12

Mathematics

Olin [163]3 years ago

Answer:

(-1/2, -13/4)

Step-by-step explanation:

Start with y = 4x^2+4x-12.  Put this into the form y = a(x-h)^2 + k, where (h, k) represents the vertex.

Factor 4 out of this expression, obtaining:  y = 4(x^2 + x - 3).

Next, complete the square of the quantity inside parentheses:

y = 4[ x^2 + x + 1/4 - 1/4 - 3 ], or

y  = 4[ (x + 1/2)^2 - 13/4 ]

We can now conclude that the vertex is (-1/2, -13/4).

Write an equation for a circle with<br> a center at (9 -2) and has a<br> radius of 7.
fenix001 [56]
The equation of a circle is given as:

(x-a)^2 + (y- b)^2 = r^2  where (a, b) is the center.

(x-9)^2  = x^2 -18x + 81 - ----(i)
(y+2)^2 =y^2 + 4y +4      ------ (ii)
r^2 = 49                          ------ (iii)

Adding equation (i) and (iii) 
x^2 + y^2 - 18x + 4y + 85 -----(iv)

Equating equation (iv) and (iii)

 <span>x^2 + y^2 - 18x + 4y + 85 = 49

Arrange the equation:

</span> <span>x^2 + y^2 - 18x + 4y + 36 = 0
</span><span>
I hope this helps

Help me with all these​
frosja888 [35]
Number 4 is C because when you do 28 times 5 your get 140 then you do 140 divided by 20 to get 7 when you do proportions to find the missing number you cross multiply with the numbers there and divide with the number that is across from the missing
Number 5 is $6 because to find the missing number you have to see which way makes sense you could do 4 divided by 3 but you get a really long number so if you do 3 divided by 4 you get .75 and you get .75 for all cost is usually the y-axis so you do y divided x so then do .75 times 8 to get the answer
Number 6 to plot them you just go in the middle of the line for the first because it is not directly 2
Number 7 to change a fraction to decimal do the numerator divided by denominator even if the denominator is bigger so 6 divided by 25 is .24 for decimal form to get the percent move the decimal point two places to the right so it will be 24%
