Graph: y = 3x - 5<br> Plz help
nexus9112 [7]

Answer:

The equation, y=3x-5 is in y=mx+b format. The b, or -5 in this case, tells you what the y intercept is, or in this case, your starting point. This means your first point will be at (0,-5). The mx, or 3x in this case, tell us how much to move     up and how much to move sideways. 3x is equal to 3/1x and the 3/1 tells us the rise/run. Rise being how much to go up or down and run being how much to go to the left or right. So in 3x, the rise is 3 and the run is 1. So you will go 3 up on the y axis and 1 to the right on the x-axis. So your next point will be (1, -2) and the point after that will be (2, 1) and so on!

hope this helped!

The three sides of a triangle are 11/3 cm , 15/4 cm and 26/9 cm . find it's perimeter .​
Verizon [17]
<h3>☘︎Answer :- </h3>

\sf\longmapsto \:  \frac{371}{36}

<h3>☘︎ Solution :- </h3>

  • Given : Three sides are 11/3 cm , 15/4 cm and 26/9 cm
  • To find : perimeter of the triangle

Perimeter of a triangle = Sum of the length of the three sides

perimeter of the given triangle = 11/3 + 15/4 + 26/9

  • Make the denominator same by taking the LCM of the denominators .

( LCM of 3 , 4 and 9 is 36 )

\sf\longmapsto \:  \frac{132 \:  +  \: 135  \: + \:  104}{36}  \:  \:  \:

\sf\longmapsto \:  \frac{371}{36} \:  cm \:

♧ Therefore, the perimeter of a triangle is 371/36 cm

Solve the following system of equations. <br> y = 12 - 5x <br> 2x + 3y = 11
Sindrei [870]
Use substitution
2x + 3(12 - 5x) = 11
Distributive property
2x + 36 - 15x = 11
Combine like terms
-13x + 36 = 11
Subtract 36
-13x = -25
x = 25/13
y = 12 - 5(25/13)
y = 31/13
Solution: x = 25/13, y = 31/13
