Answers

Answer:

Option (a) is correct.

For given values a = 1 , b = -3 , c = -5 the quadratic equation is  0=-3x-5 + x^2

Step-by-step explanation:

Given : a = 1 , b = -3 , c = -5

We have to write the quadratic equation having a = 1 , b = -3 , c = -5 and choose the correct option.

The standard form of quadratic equation is ax^2+bx+c=0 , where a, b, c are constant integers.

Given : a = 1 , b = -3 , c = -5

Then Substitute, we get,

x^2-3x-5=0  

Thus, the obtained quadratic equation is same as option (a) 0=-3x-5 + x^2

Thus, For given values a = 1 , b = -3 , c = -5 the quadratic equation is0=-3x-5 + x^2 

Answer:

a

Step-by-step explanation:

Find the values of a, b, and c. a = 41, b = 144, 36
a = 77, b = 118, c = 62
a = 36, b = 103, c = 77
a = 36, b = 118, c = 62

Answers

Answer:

The correct option is 4.

Step-by-step explanation:

If a transversal line intersect two parallel line, then the alternate interior angles are equal.

a^(\circ)=36^(\circ)

The value of a is 36.

The sum of two interior angle is equal to the exterior angle of third vertex.

77+c=139

c=139-77

c=62

The value of c is 62.

If two angles lie on a straight line, then they are supplementary angles and their sum is 180 degree.

b+c=180^(\circ)

b+62^(\circ)=180^(\circ)

b=180^(\circ)-62^(\circ)

b=118^(\circ)

The value of b is 118.

Therefore option 4 is correct.
a = 36, b = 118, c = 62

Solve for 2 unknowns
3y + 3x =24
6y+3x = 39

Answers

The two unknown variable in the two given equations are "x" and "y". 
3y + 3x = 24
Dividing both sides by 3 we get
y + x = 8 
x = 8 - y
Putting the value of y in the second equation we get
6y + 3x = 39
Dividing both sides by 3 we get
2y + x = 13
2y + 8 - y = 13
y = 13 - 8
  = 5
Putting the value of y in the first equation we get
y + x = 8
5 + x = 8
x = 8 - 5
x = 3
So the value of x is 3 and the value of y is 5. I hope the procedure is clear enough for you to understand.

Answers

1. Set each equation to each other. 2x-4=x+1
2. Subtract x from 2x. 2x-x-4=x-x+1
3. Add 4 to both sides. x-4+4=1+4
4. Answer to value of x=5.
