Help please! I need to write 4y =-3x + 12 in standard form, find the y-intercept of the previous equation, as an ordered pair, a
damaskus [11]

Answer:

-3x+4y=12\\y-intercept: (0,3)\\x-intercept: (-4,0)

Step-by-step explanation:

The standard form of a linear equation is ax+by=c, where a , b, and c are constants in the equation.

Based on the equation you have provided, the standard form would be -3x+4y=12, where a=-3, b=4, c=12.

To find the y-intercept, set x=0.

-3(0)+4y=12\\0+4y=12\\4y=12\\y=\frac{12}{4} =3

Therefore, the y-intercept is (0,3).

Do the same thing for the x-intercept, but this time with y=0.

-3x+4(0)=12\\-3x+0=12\\-3x=12\\x=\frac{12}{-3} =-4

Therefore, the x-intercept is (-4,0).

Answer:

A=266CM

Step-by-step explanation:

p=2l + 2w                                   l=2x+1             w=x+5

66=2[2x+1] + 2{x+5]                  l=2x9 + 1           w=9+5

66=4x+2 + 2x+10                      l=18+1                 w=14

66=6x+12                                   l=19

66-12=6x

54=6x                                      A=L x W

x=9                                         A=19 x 14

                                             A=266CM
