For point (1, -2): -2 = -1 - 1 = -2. Therefore, point (1, -2) lies on the graph of the equation.

The graph of the equation is the set of points that are solutions to the equation.

A coordinate pair on the graph of the equation is a solution to the equation.

For the point (0, -1): -1 = -(0) - 1 = 0 - 1 = -1.

Therefore, The point ( 0, −1 ) lies on the graph of the equation.

Step-by-step explanation:

y = 5/3x + 4

  When x = 0, y = 4

  When y = 0, x = -2.4

  graph the points: (0, 4) and (-2.4, 0)

y = -2/3x - 3

  When x = 0, y = -3

  When y = 0, x = -4.5

Write the equation in slope-intercept form through the point (-5, 3) and is perpendicular to the line y = 2x - 3 and graph​

Answers

Slope intercept form: y = mx + b

When a line is perpendicular to another line, its slope is the negative reciprocal to that slope.

From this information, we already know that the slope of our new line is -1/2, because -1/2 is the negative reciprocal to 2 (which is the slope of the original line).

y = -1/2x + b

Because the point (-5,3) is given, we can simply plug the x and y coordinates into our incomplete equation.

3 = -1/2(-5) + b

3=2.5 + b

b = 0.5

ANSWER: y = -1/2x + 0.5

THE GRAPH IS LINKED; RED LINE IS y=2x-3 AND BLUE LINE IS y=-1/2x + 0.5

9. Suppose a varies directly as b, and a = 7 when b = 2. Find b when a = 21.

Answers

Answer:

6

Step-by-step explanation:

Given expression:

    a varies directly as b;

       a ∝ b

 So;

         a  = kb  where k is the constant of proportionality;

if a= 7 and b  = 2;

         7 = 2k

           k = [tex]\frac{7}{2}[/tex]

Now, find b when a = 21

            21  =  [tex]\frac{7}{2}[/tex]  x b

           b  = 6

what is the solution to this problem? 2x+3(x-10)=45

Answers

Answer:

x= 15

Step-by-step explanation:

2x+3(x-10)=45

2x+3x-30=45

Combine like terms:

2x+3x-30 turns into 5x-30= 45

5x-30=45

   +30 +30

5x = 75

 x = 15

   

Answer:

x = 15

Step-by-step explanation:

2x+3(x-10)=45

2x+3x-30 =45

5x-30       =45

5x            =45+30

5x            =75

x              =75/5

x              =15

A side of the triangle below has been extended to form an exterior angle of 125°. Find the value of xx.

Answers

Answer: 55

Step-by-step explanation:

x+125=180

subtract 125 on each side

when you do that 125 cancels out and your left with

180-125=55

The value of x from the given triangle is 55°.

Given that, a side of the triangle below has been extended to form an exterior angle of 125°.

What are adjacent angles?

Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.

From given figure, the exterior angle of tringle is 125° and x is adjacent angle to that.

Now, 125°+x=180°

⇒ x=180°-125°

⇒ x=55°

Hence, the value of x from the given triangle is 55°.
