Solve the system. Enter the smallest x-coordinate first

pentagon [3]

$y= 3 \,\,,\,\,x= -2 \,\,and\,\, y=3\,\,,\,\, x=2$

Step-by-step explanation:

Solving the following system of equations:

$x^2-y=1\\2x^2+y^2=17$

Let

$x^2-y=1\,\,\,(1)\\2x^2+y^2=17\,\,\,(2)$

Putting value of x^2 in eq(2)

$x^2 = 1+y\\Putting\,\,value\,\,of\,\,x^2\,\,in\,\,eq(2)\\2(1+y)+y^2=17\\2+2y+y^2=17\\y^2+2y+2-17=0\\y^2+2y-15=0\\Factorizing:\\y^2-3y+5y-15=0\\y(y-3)+5(y-3)=0\\(y+5)(y-3)=0\\y+5=0 \,\,and \,\, y-3=0\\y = -5 \,\,and \,\, y=3$

Now, finding value of x

Putting y=-5

$x^2 = 1+y\\x^2=1-5\\x^2=-4\\Taking\,\,square\,\,root\\x= \pm2i$

y=-5, x= 2i and y=-5 , x= -2i

Since we need to find x and y coordinates and its value cannot be in terms of i so we will not consider these as answer

Putting y=3

$x^2 = 1+y\\x^2=1+3\\x^2=4\\Taking\,\,square\,\,root\\x= \pm2$

So, $y= 3 \,\,,\,\,x= -2 \,\,and\,\, y=3\,\,,\,\, x=2$

Answer:

${105cm}^{2}$

Step-by-step explanation:

Im assuming it's asking for the area of the shape.

We need to break the shape into two sections as shown in the picture. First we find the area of the rectangle (9×10)

90cm^2

Now for the triangle section (3×10)÷2

15cm^2

Now add up the two amounts.

A television set manufacturing firm has to decide on the mix of color and black-and-white TVs to be produced. A market research

zhannawk [14.2K]

Answer:

Objective Function, $Max P =60c+30b$

Subject to the Constraints

$0$

$0$

$20c+15b\leq 60000$

Step-by-step explanation:

Let the number of black t.v. produced =b

Let the number of colored t.v. produced =c

at most, 2000 units of color t.v. can be sold i.e. $c\leq 2000$

at most 4000 units of black-and-white TVs can be sold i.e. $b\leq 4000$

Total man hours per product = Number of Units X Man Hour Per Unit

A color TV requires 20 man-hours = 20c

A black-and-white TV requires 15 man-hours =15b

Since Maximum number of man Hours is 60000 hours

$20c+15b\leq 60000$

The unit profits of the color TV is $60, therefore total profit =60c

The unit profits of the black-and-white TVs $30, respectively, therefore total profit =30b

Since we are to maximize profit, the Objective Function, $Max P =60c+30b$
