If x = 3, y=-1 is a solution of the equation 3x - 2y = k, then k is :
(a) 12
(b) 10
(c) 7
(d)11

Answers

Answer 1

Answer:

11

Step-by-step explanation:

So you replace each letter with it's numerical value.

Note that in arithmetics the sign is critical so observe it.

For this equation, if you solve for k by replacing the known variables with their actual value you get this:

3(3)-2(-1)=k

As stated earlier, the signs are important. When you multiply a negative number with another negative number the sign becomes positive (+).

For this case, -2*-1=+2 and 3*3=9

So, k=2+9

k is therefore 11

Answer:

y = 5

Step-by-step explanation:

first you subtract 5y from itself and from 7y

then you'll get: 2y + 2 < 12

then subtract the 2 from itself and from the 12

that will give you: 2y < 10

then just divide the 2 from itself and that eliminates the 2 but keeps the y, and divide the 10 by the 2

that'll give you y = 5

Given pair of linear equations in two variables are :

7x-3y = 8------------(1)

3x-4y = 1-------------(2)

On multiplying (1) with 3 then

21x-9y = 24 ---------(3)

On multiplying with 7 then

21x-28y = 7 ----------(4)

On subtracting (4) from (3) then

21x-9y = 24

21x-28y = 7

__________

0+19y = 17

__________

→ 19y = 17

→ y = 17/19

On substituting the value of y in (2) then

→ 3x-4(17/19) = 1

→ 3x -(68/19) = 1

→ (57x-68)/19 = 1

→ 57x-68 = 1×19

→ 57x -68 = 19

→ 57x = 19+68

→ 57x = 87

→ x = 87/57

Therefore, the value of x and y is 87/57 and 17/19 respectively.

The length of AB is equal to the length of BC
What are the coordinates of point A?
*C(5,6)
*B12, 1)

Answers

Answer:

(-1,-4)

Step-by-step explanation:

First, you take the x coordinate of C and subtract it from the x coordinate of B. 5-2=3. You then take the 3 and subtract it from the x value of point B which is 2 and 2-3=-1 which gives us the x coordinate of point A -1. then you take the Y coordinate of C and subtract it from the Y coordinate of B. 6-1=5. You then take the 5 and subtract it from the y value of point B which is 1 and 1-5=-4 which gives us the y coordinate of point A -5. And that gives you (-1,-4)

Solution :

The volume of prism is the amount of space a prism occupies. It has two same faces and other faces that resemble a parallelogram.

Let the height of the prism be h.

Now, substitute the value of base area and volume of the rectangular prism in the given equation (1).

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The volume of prism is the amount of space a prism occupies. It has two same faces and other faces that resemble a parallelogram.

Let the height of the prism be h.

Now, substitute the value of base area and volume of the rectangular prism in the given equation (1).

x⁴ + 4x³ + 3x² + 8x + 4 = (x³ + 3x²+8)h

Divide both sides by  (x³ + 3x²+8)

h=(x⁴ + 4x³ + 3x² + 8x + 4)/(x³ + 3x²+8)

h=(x+1)((x³ + 3x²+8)-4)/(x³ + 3x²+8)

h=(x+1) - 4//(x³ + 3x²+8)

Hence, If the volume of a rectangular prism is the product of its base area and height, than the height of the prism is given by (x+1) - 4//(x³ + 3x²+8)
