Whats the vertex form of y=x^2-20x+15

1 answer:

6 0

This looks like a parabola so:
y=x^2 - 20x + 15 --> x^2 - 20x +15=y
(x^2 -20x)=y - 15 --> (x - 10)^2=y - 15 +100 ( used complete the square)
(x - 10)^2=y + 85

Answer:

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\\text{Substitute}\ f(x)=3x+1,\ g(x)=x^2-6:\\\\(f+g)(x)=(3x+1)+(x^2-6)\qquad\text{combine like terms}\\\\(f+g)(x)=x^2+3x+(1-6)\\\\(f+g)(x)=x^2+3x-5$

Expanding triple brackets, i will give brainliest

rewona [7]

Answer:

${x}^{3} + {x}^{2} −24x+36$

Step-by-step explanation:

$(x + 6)(x - 2)(x - 3)$

$[x(x−2)+6(x−2)](x−3)$

$( {x}^{2} −2x+6x−12)(x−3)$

$( {x}^{2} +4x−12)(x−3)$

${x}^{3} + {x}^{2} −24x+36$

What is the value of y in the equation 4(5y –8 –2) = 185 –15?

Rina8888 [55]

In an equation the Left hand side must equal the right hand side 4(5y-8-2)=185-15 20y-32-8=170 20y=170+32+8 20y=210 Therefore y=10,5 When you substitute the 10,5 and solve it on the left and side it's equal to 170 which is the answer on the right hand side
