Y ≥ 12x – 1<br> y &lt; 43x – 2
kondaur [170]

Answer:

Step-by-step explanation:

The solution to this problem is a graph.

Graph y ≥ 12x - 1:  this is a straight solid line with slope 12 and y-intercept -1.  Due to the presence of the  ≥  operator, we must shade (darken) the entire area above this line.  

Next, graph y < 43x – 2 using a dashed line (due to the < operator):  The slope is 43 and the y-intercept is -2.

Determine where the two lines intersect, either from the graph or algebraically.  If algebraically:

equate the two givens:

y = 12x - 1 = y = 43x – 2, which simplifies first to:

12x - 1 = 43x - 2, and second to

1 = 43x - 12x = 31x, which results in x = 1/31.

Substituting 1/31 for x in the first equation, we get:

y = 12(1/31) - 1, or y = 12/31 - 1, or y = 12/31 - 31/31, or y = 19/31

The two graphs intersect at (1/31, 19/31)

Shade (darken) the area beneath (under) the dashed line y < 43x – 2.

The solution is the area that you have darkened twice.

According to the graph, what is the value of the constant in the equation below?
kow [346]

Option B: 50 is the value of the constant.

Explanation:

From the graph, the coordinates are (4,12.5) , (5,10) , (10,5) and (20,2.5)

Where the x coordinates denotes the width and the y - coordinates denotes the height.

Also, given that Height =\frac{ { Constant }}{{ Width }}$

We need to determine the value of the constant

<u>Value of the constant:</u>

The value of the constant can be determined using the formula,

Height \times weight=Constant

Since, all the coordinates lie on the same line, then all the coordinates have the constant.

Substituting the coordinate (4,12.5) in the above formula, we get,

4\times 12.5=Constant

       50=Constant

Therefore, the value of constant is 50.

Hence, Option B is the correct answer.

Please help!! I will give brainliest thank you!!

\bold{\huge{\red{\underline{Solution}}}}

\bold{\underline{ Given :- }}

  • We have given two figures that rectangle and parallelogram
  • The base and height of parallelogram is 7ft and 5ft
  • The length and breath of rectangle is 3ft and 1ft .

\bold{\underline{ To \: Find :- }}

  • We have to find the area of shaded part?

\bold{\underline{ Let's \: Begin :- }}

Firstly, we will calculate the area of parallelogram then area of rectangle after that we will subtract the area of rectangle from the area of parallelogram then we got the area of shaded part.

\sf{\pink{Area \:of\: parallelogram = Base * height }}

\sf { = 7 × 5 }

\sf { = 35ft }

\sf{ Thus,  \:The \:area\: of \:parallelogram\: is \:35ft}

\sf{\underline{ Now}}

\sf{\blue{Area\: of\: rectangle = L × B }}

\sf{ = 3 × 1 }

\sf{ = 3ft}

\sf{Thus, \:The\: Area\: of \:rectangle\: is\: 3ft}

\sf{\underline{ Now}}

\sf{ Total\: area \:of \:shaded\: part }

\sf{ Area\: of\: parallelogram - Area\: of\: rectangle }

\sf{ = 35 - 3}

\sf{ = 32 ft}

\bold{\pink{Hence, \: Area\: of \:shaded\: part \:is\: 32ft}}
