Unless you give the value of y, then you can’t solve for x in this expression. It’s not possible.

It’s because x can equal anything since y doesn’t have a value yet.

For example, if y=11 then x would be 2. Because 4 multiplied by 2 is 8, plus 3 is 11.

Answer:

B = 10.5

Step-by-step explanation:

From the figures, it looks like triangle HER is similar to triangle KPS.

From that we get

\dfrac{HE}{KP} = \dfrac{ER}{SP}

\dfrac{B}{7} = \dfrac{7.5}{5}

Multiply both sides by 7.

B = 10.5

A right triangle has a 30o angle. the leg adjacent to the 30o angle measures 25 inches. what is the length of the other leg
adelina 88 [10]
Since the triangle has a 30° angle and a right angle which is 90°, this triangle must be a 30 - 60 - 90 triangle, which is a triangle with special properties. The length of the leg adjacent to the 30° angle is equal to the √3 times x where x is the length of the angle adjacent to the 60<span>° angle. Here is a visual representation:

The shaded region in the graph represents the solutions of this system of linear inequalities:
kotegsom [21]

Answer:

y

y\leq 2x+3

Step-by-step explanation:

step 1

Find the equation of the solid line

From the graph take the points (0,3) and (4,11)

Find the slope

m=(11-3)/(4-0)\\m=8/4=2

The equation of the solid line in slope intercept form is equal to

y=mx+b

we have

m=2

b=3 ----> the y-intercept is the point (0,3)

substitute

y=2x+3

therefore

The inequality is

y\leq 2x+3

step 2

Find the equation of the dashed line

The slope is given

m=4

From the graph take the y-intercept (0,-5)

The equation of the solid line in slope intercept form is equal to

y=mx+b    

we have

m=4

b=-5

substitute

y=4x-5

therefore

The inequality is

y

because the shaded region is below the dashed line

therefore

The system of inequalities is

y

y\leq 2x+3
