The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y > −2x + 10 y > 1 o
jarptica [38.1K]

Point B is a solution to the system of inequalities  

<h3>Further explanation  </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates  

General formula  

\large{\boxed{\bold{y-y_1=m(x-x_1)}}

or  

y = mx + c  

Where  

m = straight-line gradient which is the slope of the line  

x1, y1 = the Cartesian coordinate that is crossed by the line  

c = constant  

The formula for a gradient (m) between 2 points    

\large{\boxed{\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}}

If the intersection of the x-axis (b, 0) and the y-axis (0, a) then the equation of the line:  

ax + by = c

It says inequality if there are symbol forms like <, >, ≤ or ≥  

Whereas linear inequality can have forms:  

ax + by> c, ax + by ≥ c , ax + by <c , ax + by ≤ c  

In graphical form, line inequality can be  

• dashed line because y does not include equals to  

• a solid line because y includes equal to  

For line inequality (positive coefficient y)  

ax + by ≥ c then the solution is shaded upwards  

ax + by ≤ c then the solution is shaded down  

(Picture attached)

The line :

\displaystyle y>-2x+10

intersect x-axis at point : 5,0

Intersect y-axis at point : 0,10

And the solution  is shaded upwards  

\displaystyle y=\frac{1}{2}x-2

intersect x-axis at point : 4,0

Intersect y-axis at point : 0,-2

And the solution  is shaded upwards  

And the point located in the shaded plane of the two inequality is point B and I

(Tough day dividing polynomials and I'm still lost!) Please help me my hands are legit numb:)
N76 [4]

Answer:

Option D. 9

Step-by-step explanation:

There are two ways to obtain the answer to the question.

Method 1:

Let 2x + 1 = 0

Making x the subject, we have

2x + 1 = 0

Collect like terms

2x = –1

Divide both side by 2

x = –1/2

Now, put the value of x into the expression 4x³ – 6x² – 8x + 7, we have:

4x³ – 6x² – 8x + 7

x = –1/2

4(–1/2)³ – 6(–1/2)² – 8(–1/2) + 7

4(–1/8) – 6(1/4) – 8(–1/2) + 7

–1/2 – 3/2 + 4 +7

– 4/2 + 4 + 7

– 2 + 4 + 7

= 9

Method 2:

Divide 4x³ – 6x² – 8x + 7 by 2x + 1

Please see attached photo for explanation.

Dmitry [639]

Answer:

slope of AB=2

AB(distance)=4√5

Step-by-step explanation:

slope of AB=6-(-2)/-4-(-8)

=2

AB=√(-8-(-4))^(2+(-2-6)^(2

=4√5 or 8.94427

next time pls type clearly ur question, because actually I don't know what kind of answer that u want to know. sorry

Simon has a certain length of fencing to enclose a rectangular area. The function AAA models the rectangle's area (in square met
pav-90 [236]

Answer:

When there is no width, the area is 0m²

Step-by-step explanation:

Expressing the area of a rectangle as a function of its width:

Area of a rectangle = Length * width

Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0

When x :

Area = Length * width

Area = Length * 0

Area = 0

Area = Length * 0

Aea = 0
