What is x in this equation- 3/2x-7=-11

Sunny_sXe [5.5K]

3/2x-7=-11

We move all terms to the left:

3/2x-7-(-11)=0

Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R

We add all the numbers together, and all the variables

3/2x+4=0

We multiply all the terms by the denominator

4*2x+3=0

Wy multiply elements

8x+3=0

We move all terms containing x to the left, all other terms to the right

8x=-3

x=-3/8

A rhombus has coordinates A(-6, 3), B(-4, 4), C(-2, 3), and D(-4, 2). What are the coordinates of rhombus A′B′C′D′ after a 90° c

Liula [17]

We are given that the coordinates of the vertices of the rhombus are:
A(-6, 3)
B(-4, 4)
C(-2, 3)
D(-4, 2)

To solve this problem, we must plot this on a graphing paper or graphing calculator to clearly see the movement of the graph. If we transform this by doing a counterclockwise rotation, then the result would be:
A(-6, -3)
B(-4, -4)
C(-2, -3)
D(-4, -2)

And the final transformation is translation by 3 units left and 2 units down. This can still be clearly solved by actually graphing the plot. The result of this transformation would be:

A′(6, -8)
B′(7, -6)
C′(6, -4)
D′(5, -6)

Grace [21]

The number of batches of salsa that can be made = x = 6 batches

The number of bat tomato sauce that can be made = y = 3 batches

Step-by-step explanation:

We are given the system of equations:

$x+5y=21\\x+y=9$
