i need help with a few problems.
1. find 3 solutions to the equation y=7x-5
studiousness
To find three solutions to the equation y = 7x - 5, we can substitute different values of x and calculate the corresponding values of y. Here are three possible solutions:
Solution 1:
Let's take x = 1.
Substituting x = 1 in the equation, we get:
y = 7(1) - 5
y = 7 - 5
y = 2
So, one solution is x = 1, y = 2.
Solution 2:
Let's take x = 0.
Substituting x = 0 in the equation, we get:
y = 7(0) - 5
y = 0 - 5
y = -5
So, another solution is x = 0, y = -5.
Solution 3:
Let's take x = -1.
Substituting x = -1 in the equation, we get:
y = 7(-1) - 5
y = -7 - 5
y = -12
So, the third solution is x = -1, y = -12.
Therefore, three solutions to the equation y = 7x - 5 are:
(1, 2), (0, -5), (-1, -12).
To find three solutions to the equation y = 7x - 5, you can choose any three values for x and calculate the corresponding values for y. Here's how to do it:
1. Choose a value for x. Let's say x = 0.
2. Substitute the value of x into the equation: y = 7(0) - 5
3. Simplify the equation: y = -5
4. So, one solution is (x, y) = (0, -5).
Now, let's find two more solutions.
1. Choose another value for x. Let's say x = 1.
2. Substitute the value of x into the equation: y = 7(1) - 5
3. Simplify the equation: y = 7 - 5 = 2
4. So, another solution is (x, y) = (1, 2).
Now, let's find the third solution.
1. Choose another value for x. Let's say x = -1.
2. Substitute the value of x into the equation: y = 7(-1) - 5
3. Simplify the equation: y = -7 - 5 = -12
4. So, the third solution is (x, y) = (-1, -12).
Therefore, three solutions to the equation y = 7x - 5 are: (0, -5), (1, 2), and (-1, -12).
pick any value for x, say 0
Then y = 7*0-5 = -5
Surely you can pick two other values for x and work the same magic ...
