A 66-meter garden row is divided into 44 equal-sized sections to plant onions.

Gwar [14]

You may represent this multiple ways.

1. 66/44 = m

2. 44m = 66

In both of these scenarios you have a total and equal parts.

The first one starts with a total and breaks it into equal parts.

The second choice shows 44 groups of a part totaling 66 meters.

a=1
b=6
c=-59
x= $\frac{-6+/- \sqrt{(6)-4(1)(-59)} }{2(1)}$
x= $-3+ 2\sqrt{17}$ and $-3- 2\sqrt{17}$

what’s the slope and y intercept of the loire that is perpendicular to y=-2x-5 and passes through the point (-3,-6)

Doss [256]

Answer:

slope: ½

y-intercept: -4½

Step-by-step explanation:

Slope: negative reciprocal of -2

-1/-2 = 1/2

y = ½x + c

-6 = ½(-3) + c

-6 = -3/2 + c

c = -6 + 3/2

c = -9/2 = -4½

morpeh [17]

Answer:

The final result is 1

Step-by-step explanation:
