x = 10

Step-by-step explanation:

Since the parallelograms are similar then the ratios of corresponding sides are equal , that is

= ( cross- multiply )

6x = 60 ( divide both sides by 6 )

Which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded?

harkovskaia [24]

Answer: Below the solid line

Step-by-step explanation:

-4y - x ≥ 7

add x to both sides

-4y ≥ x + 7

divide by -4 on both sides

y ≤ -1/4x - 7/4 = (1.75)

Take the origin (0,0) and substitute it for the variables

y(0) ≤ -1/4(0) - 7/4

0 ≤ -7/4 = (1.75)

This statement is false, so you would shade on a graph, below the solid line, since this is where the origin would not be.

The line would be solid because the < is underlined.

$\huge\text{Hey there!}$

$\large\boxed{\rm{\dfrac{ab^2 - 4}{10}}}$

$\large\boxed{\rm{\rightarrow\dfrac{\bold{4(6)}^2 -4}{10}}}$

$\large\boxed{\rm{6^2}}$

$\large\boxed{\rm{= 6 \times6}}$

$\large\boxed{\rm{= \bf 36}}$

$\large\boxed{\rm{\rightarrow\dfrac{4(\bold{36)}- 4}{10}}}}$

$\large\boxed{\rm{4(36)}}$

$\large\boxed{\rm{= \bf 144}}}$

$\large\boxed{\rm{\rightarrow\dfrac{\bold{144} - 4}{10}}}$

$\large\boxed{\rm{\bold{144} - 4}}$

$\large\boxed{= \rm{\bf 140}}}$

$\large\boxed{\rm{\rightarrow\dfrac{\bold{140}}{10}}}$
