(-3,5),(-2,-6)
slope = (-6 - 5) / (-2 - (-3) = -11 / (-2 + 3) = -11/1 = -11

y = mx + b
slope(m) = -11
use either of ur points...(-3,5)...x = -3 and y = 5
now sub and find b, the y int
5 = -11(-3) + b
5 = 33 + b
5 - 33 = b
- 28 = b
so ur equation is : y = -11x - 28...but we need it in standard form Ax + By = C

y = -11x - 28.....add 11x to both sides
11x + y = -28 <== standard form

Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width
kondor19780726 [428]

Answer:

(40+2b)cm

Step-by-step explanation:

Complete question

Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.

To get the amount of fencing material needed, we will find the perimeter of the fence

perimeter of the fence = 2(L+W)

L is the length

W is the width

Given

Length = 20feet

Width = b feet

perimeter of the fence = 2(20+b)

perimeter of the fence = 2(20) + 2b

perimeter of the fence = 40+2b cm

Hence the amount of material needed will be (40+2b)cm

Write the expression that appears under the radical symbol in the quadratic formula. what is the quality called? what can it be
ira [324]
This expression is called the Discriminant, also shown as Δ.
It is equal to b² - 4ac. This is a very important part of the quadratic formula as it determines whether x will have two values, one repeated value or no real values. Here are a few examples.

a) x² - 2x - 1. a is equal to 1 since 1x² = x². b = -2, c = -1
The discriminant will be (-2)² - 4×1×-1 = 4 + 4 = 8.
Since Δ > 0, there are two x values. Graphed, the parabola sinks below the x axis.

b) x². a = 1, b = 0 (0x = 0), c = 0
The discriminant will be 0² - 4×1×0 = 0 - 0 = 0.
Since Δ = 0, there is only one x value. Graphed, the parabola touches the x axis at only one point.

c) x² + 1. a = 1, c = 1.
The discriminant will be 0² - 4×1×1 = 0 - 4 = -4
Since Δ < 0, there are no real x values. Graphed, the parabola floats above the x axis.

Hope this helps!
