Answer:
No solution
Step-by-step explanation:
-3x + 3y = 4
-x + y = 3
<u>Solve the equation for x:</u>
<u>Move the variable to the right side and change its sign</u>
-x + y = 3
-x = 3 - y
<u>Change the signs on both sides of the equation</u>
-x = 3 - y
x = -3 + y
<u>Substitute the given value of x into the equation -3x + 3y = 4</u>
-3x + 3y = 4
x = -3 + y
-3(-3+y)+3y=4
<u>Solve the equation for y</u>
-3(-3+y)+3y=4
y = 0
There is no solution for y.
And since there's no solution for y, the system has no solution.
What is the situation from the problem
Answer:
D. -2
Step-by-step explanation:
The zero of a function is always along the x-axis and in this case that's -2.
Hope this helps :)
24 and 28
These are the only two numbers (other than 20 itself) that have a factor of 4. And if you were to find all of their common factors, 4 would be the greatest!
Answer:
A
Step-by-step explanation:
We can plug in all of the x and y values to check if the point is a solution to the inequality.
Point A: x = 1, y = 7
7 > |1| + 5
7 > 1 + 5
7 > 6
This is a true statement, which means that this point is a solution to the inequality. We don't have to check any more points since we have found our answer.
