Answer:

-10xsquared-x+38

Step-by-step explanation:

so,

general eqn of quadratic equation is,

axsquared+bx+c=y

where,

x and y are exchanged by coordinates given in qn

1,64a-8b+c=0

2,4a-2b+c=0

or c=2b-4a

60a-6b=0

3,36a-6b+c=8

32a-4b=8

Given that f(x) = x^2 + 4x, evaluate f(-2)

atroni [7]

Hi there!

To find f(-2), we need to plug in the value x = -2 into the equation.

$f( - 2) = ( - 2) {}^{2} + 4 \times - 2 = 4 - 8 = - 4$
Remember that multiplying a negative by a positive ends up with a positive.

SOMEONE PLEASE HELP ME

notka56 [123]

Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)

456=40w+4w^2+100w

456=4w^2+140w

114=w^2+35w

0=w^2+35w-114

find what 2 numbers multiply to get 114 and add to get 35 and factor

-3 and 38

0=(w-3)(w+38)

set each to zero

w-3=0

w=3

A line passes through point (8, -8) and has a slope of -3/2 . Write an equation in Ax+By=C form for this line. Use integers for

olchik [2.2K]

y = -3/2(x) + b

-8 = -3/2(8) + b

-8 = -12 + b

b = 4

y = -3/2(x) + 4

3/2x + y = 4

Hope this helps!! :)
