Find the values of x and y that make the following quadrilateral a parallelogram.

lidiya [134]

Answer:

x = 3 and y = 14

Step-by-step explanation:

opposite angles of a parallelogram are congruent. Hence,

1) 7y + 2 = 6y + 16

I. e. 7y - 6y = 16 - 2

I. e. y = 14

2) 8x + 8 = 6x + 14

I. e. 8x - 6x = 14 - 8

I. e. 2x = 6

I. e. x = 6/2

I. e. x = 3

Two functions are defined as shown. f(x) =-1/2 x – 2 g(x) = –1 Which graph shows the input value for which f(x) = g(x)?

Natalka [10]

Answer:

See attachment.

Step-by-step explanation:

The given functions are:

$f(x) = - \frac{1}{2}x - 2$

and g(x)=-1

To find the x-value of the point of intersection of the two functions, we equate the two functions and solve for x.

$- \frac{1}{2}x - 2 = -1$

$x + 4 = 2$

$x = 2 - 4 = - 2$

The graph that shows the input value for which f(x)=g(x) is the graph which shows the point of intersection of f(x) and g(x) to be at x=-2.

Use the drop-down menus to choose steps in order to correctly solve 1+2b−13=12−4b−2b for b.

alexira [117]

Answer:

$b=3$

Step-by-step explanation:

Given equation:

$1+2b-13=12-4b-2b$

Solving for $b$

Combining like terms on both sides.

$2b+1−13=12-4b-2b$

$2b-12=12-6b$

Adding $6b$ both sides to get $b$ terms on one side.

$2b-12+6b=12-6b+6b$

$8b-12=12$

Adding 12 both sides to isolate $b$ on one side.

$8b-12+12=12+12$

$8b=24$

Dividing both sides by 8.

$\frac{8b}{8}=\frac{24}{8}$

∴ $b=3$ (Answer)
