Answer:

The linear inequality would be y ≥ 1/2x - 1

Step-by-step explanation:

In order to find the inequality, first find the equation of the line. To do this, we start by identifying two points on the line. For the purpose of this, we'll use (0, -1) and (2, 0). Now we can use the slope formula to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (0 - -1)/(2 - 0)

m = 1/2

Now that you have the slope, you can use either point and point-slope formula.

y - y1 = m(x - x1)

y - 0 = 1/2(x - 2)

y = 1/2x - 1

Now that we have this, we look to the shading. If the shading is above, then we make y ≥. If it is under the line, then we make y ≤. In this case, the shading is above. Leaving us with:

y ≥ 1/2x - 1

Answer:

y\geq\dfrac{1}{3}x-1

Step-by-step explanation:

Given: The graph of inequality.

First choose two points on graph and find the equation of line.

From graph two passing points are (3,0) and (0,-1)

using two point formula of line to find the equation.

y-(-1)=\dfrac{0+1}{3-0}(x-0)

y+1=\dfrac{1}{3}x

y=\dfrac{1}{3}x-1

Now we find inequality.

Line is solid on graph. Equality would be there.

point (0,0) is part of shaded region.

(0,0) must be true for above equation.

Check the points

0 \text{___} \dfrac{1}{3}(0)-1

0 \text{___} -1

As we know 0 is greater than -1.

Hence, The equation of inequality y\geq\dfrac{1}{3}x-1

Sophie [7]

Answer:

The length of DE is 14 cm.

Step-by-step explanation:

Given in triangle ABC segment DE is parallel to the side AC . (The endpoints of segment DE lie on the sides AB and BC respectively). we have to find the length of DE.

Given lengths are AC=20cm, AB=17cm, and BD=11.9cm

In ΔBDE and ΔBAC

∠BDE=∠BAC       (∵Corresponding angles)

∠BED=∠BCA       (∵Corresponding angles)

By AA similarity rule, ΔBDE~ΔBAC

∴their corresponding sides are in proportion

⇒ \frac{BE}{BC}=\frac{BD}{BA}=\frac{DE}{AC}

⇒ \frac{BD}{BA}=\frac{DE}{AC}

⇒ \frac{11.9}{17}=\frac{DE}{20}

⇒ DE=\frac{20\times 11.9}{17}=14cm

Solve x2+12x=-11 by completing the square . Which is the the solution set of the equation?
Dmitriy789 [7]

Answer:

{- 11, - 1 }

Step-by-step explanation:

Since the coefficient of the x² term is 1 , to complete the square

add (half the coefficient of the x-term )² to both sides

x² + 2(6)x + 36 = - 11 + 36 ← complete the square on the left side

(x + 6)² = 25 ( take the square root of both sides

\sqrt{(x+6)^2} = ± \sqrt{25}

x + 6 = ± 5 ( subtract 6 from both sides )

x = - 6 ± 5

x = - 6 + 5 = - 1 or x = - 6 - 5 = - 11
