Re-write the quadratic function below in Standard Form y= -9(x+3)2+2
disa [49]

Answer:

18x+y=-52

Step-by-step explanation:

we all know and love(being 100% sarcastic here)the standard form  as

ax+by=c

y=-9(x+3)*2+2----This is weird and not so nice

so lets make it nice by distributing the 9::::

y=(-9x-27)2+2

and now the 2:

y=-18x-54+2

y=-18x-52

oops this is NOT in S.F we got to switch the -52 and y

52=-18x-y

-18 cant be neg. so we have to divide by -1 on both sides

-52=18x+y

18x+y=-52

HOPE THIS HELPS

3(x-2)=18 I need help like asap
Naily [24]

Answer: <u><em>x=8</em></u>

Step-by-step explanation:

Simplifying

3(x + -2) = 18

Reorder the terms:

3(-2 + x) = 18

(-2 * 3 + x * 3) = 18

(-6 + 3x) = 18

Solving

-6 + 3x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6' to each side of the equation.

-6 + 6 + 3x = 18 + 6

Combine like terms: -6 + 6 = 0

0 + 3x = 18 + 6

3x = 18 + 6

Combine like terms: 18 + 6 = 24

3x = 24

Divide each side by '3'.

x = 8

Simplifying

x = 8

Graph f(x)=12x+2.<br><br> Use the line tool and select two points to graph the line.
Alex73 [517]

Answer:

(0,2) and (1,14)

Graph is attached.

Step-by-step explanation:

Let us find  y intercept

When x=0, y  = f(x) =2

Hence one point is (0,2)

Other point is let x = 1,

y =12(1)+2 =14

(1,14) (0,2) are plotted and joined.

Graph is attached.
