Match the equation with its graph 15x -12y=60

Mathematics

IgorLugansk [536]3 years ago
6 0

Answer:

Check the attached graph for correct match.

Step-by-step explanation:

Graph of the given choices are not given but we can still solve this problem.

Given equation is  15x-12y=60.

Which is linear equation so we need at least two points to get the graph.

We are free to select any random number of x then plug that into given equation to find other variable.

Let's use x=0

15x-12y=60

15*0-12y=60

0-12y=60

-12y=60

divide both sides by -12

y=-5

Hence point is (0,-5)

Similarly plug y=0

15x-12y=60

15x-12*0=60

15x-0=60

15x=60

divide both sides by 15

x=4

Hence point is (4,0)

Now graph both points then join them by a straight line.

Any graph given in the choices which match with attached graph will be the answer.

Check the attached graph for correct match.

Find the value of x.
allochka39001 [22]

In order to find the value of x, you have to cross multiply both equations. 4x-10 is basically 4 times something subtract 10. Same thing as well for 3x-2. Now it says to find the value of x. X has to also be the same answer for both equation as well. By the way x doesn't have a given number so there is no specific answer.

During batting practice 12 balls were pitched to each player if 9 player came to practice how many balls were pitched
svetoff [14.1K]
Hello,

If 12 balls were pitched to each of the 9 players at practice, then
12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 balls were pitched total.

This is also equal to (12)(9) = 108 balls.

108 balls were pitched during practice.

Hope this helps!

What is the slope of the line that passes through the points (1, -2) and (3, -5)?
Ksivusya [100]

Slope of the line is -3/2

Step-by-step explanation:

  • Step 1: Given points are (1, -2) and (3, -5)
  • Step 2: Equation for slope, m = (y2 - y1)/(x2 - x1)

⇒ m = (-5 - -2)/(3 - 1) = -3/2
