Answer:
The answer is the second one
im sorry if this is wrong
Step-by-step explanation:
The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.
The answer to the solution of the equation 5x+2y=-1 is 1,-3)
Answer:
Two solutions were found :
x = -4
x = 1/2 = 0.500
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
(2x - 1) • (x + 4) = 0
Step 2 :
Theory - Roots of a product :
2.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :
2.2 Solve : 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2 = 0.500
Solving a Single Variable Equation :
2.3 Solve : x+4 = 0
Subtract 4 from both sides of the equation :
x = -4
Two solutions were found :
x = -4
x = 1/2 = 0.500

plz mark me as brainliest :)
Answer:
the slope is 1 up and 7 left (mx part of the equation) and the 2 is where you start on the y axis. So you start at 2 on the vertical axis, and move up one and left 7, and put a point on where you land and continue.
Step-by-step explanation:
It should look something like this: hope this helps :)
