The formula for the area of a trapezoid is A=1/2h(b1+b2) express b1 in terms of A, h and b2

Answers

The expression of  b1 in terms of A, h, and b2 is expressed as b_1 =(2A)/(h) - b_2

Given the formula for calculating  the area of a trapezoid expressed as:

A = (1)/(2)h(b_1+b_2)

We are to express b1 in terms of A, h, and b2 as shown

A = (1)/(2)h(b_1+b_2)\n2A = h(b_1+b_2)\n(2A)/(h) = b_1 + b_2\n b_1 =(2A)/(h) - b_2

Hence the expression of  b1 in terms of A, h, and b2 is expressed as b_1 =(2A)/(h) - b_2

the answer is b1=(2A/h)-b2

What is the x-coordinate of the solution of the following system of equations?3x + y = 6
x - y = 6

a. -3
b. 0
c. 3

Answers

Answer:

The x-coordinate of of the solution of  system of equations is 3.

Option (c) is correct .

Step-by-step explanation:

As the system of equations are

3x + y = 6

x - y = 6

Now multiply x - y = 6 by 3 and subtrated from 3x + y = 6  .

3x - 3x + y + 3y = 6 - 18

4y = -12

y = (-12)/(4)

y = -3

Put in the x - y = 6

x - (-3) = 6

x + 3 = 6

x = 6 -3

x = 3

Therefore the x-coordinate of of the solution of  system of equations is 3.

Option (c) is correct .

c because x is equal to 3

Answers

Answer:

x = -1/3 - 3/2y

Step-by-step explanation:

Step 1: Write out equation

3y + 2x = -1

Step 2: Subtract 3y on both sides

3y - 3y + 2x = -1 - 3y

2x = -1 - 3y

Step 3: Divide both sides by 2

2x/2 (-1 - 3y)/2

x = -1/3 - 3/2y

Answer:

Hey there!

3y+2x=-1

2x=-3y-1

x=-3/2y-1/2

Let me know if this helps :)
