Graph the system of inequalities to show all possible solutions.<br> {y&lt;3x-2<br> {y ≥ -x+3
Semmy [17]

Answer:

see attachment for graph

Step-by-step explanation:

< or > : dashed line

≤ or ≥ : solid line

< or ≤ : shade below the line

> or ≥ : shade above the line

<u>To graph the line y < 3x-2</u>

Rewrite the equation as: y = 3x - 2

Find two points on the line:

when x = 0,  y = 3(0) - 2 = -2  →  (0, -2)

when x = 3,  y = 3(3) - 2 = 7  →  (3, 7)

Plots the found points (0, -2) and (3, 7).

Draw a straight, dashed line through the points.

<u>To graph the line y ≥ -x + 3</u>

Rewrite the equation as: y = -x + 3

Find two points on the line:

when x = 0,  y = -(0) + 3 = 3  →  (0, 3)

when x = 3,  y = -(3) + 3 = 0  →  (3, 0)

Plots the found points (0, 3) and (3, 0).

Draw a straight, solid line through the points.

Shade above the solid line and below the dashed line to the right of where the two lines intersect.  <u>The shaded area is the area of all possible solutions</u>.

Find the length of the hypotenuse.​
IRISSAK [1]

Answer:

6

Step-by-step explanation:

Using the sine ratio in the right triangle

let x = hypotenuse and sin45° = \frac{\sqrt{2} }{2}, then

sin45° = \frac{opposite}{hypotenuse} = \frac{3\sqrt{2} }{x}

and

\frac{3\sqrt{2} }{x} = \frac{\sqrt{2} }{2} ( cross- multiply )

\sqrt{2} × x = 6\sqrt{2}

Divide both sides by \sqrt{2}

x = 6

IM TAKING THE TEST RN PLEASE HELP ME ASAP :(
12345 [234]

Answer:

Step-by-step explanation:

x=17

Let's solve your equation step-by-step.

6(x−5)=72

Step 1: Simplify both sides of the equation.

6(x−5)=72

(6)(x)+(6)(−5)=72(Distribute)

6x+−30=72

6x−30=72

Step 2: Add 30 to both sides.

6x−30+30=72+30

6x=102

Step 3: Divide both sides by 6.
