Answer:
The answer is 11/8 or 1 3/8
Step-by-step explanation:
First, you can break both fractions down into 3+1/4-1+7/8.
Second, use 3 subtract 1, you will get 2+1/4-7/8.
To subtract 7/8 you have to make both numbers denominator same.
1/4 will multiply by 2 on the top and the bottom.
After that, you will get 2 2/8-7/8.
2x8=16, 16+2=18
18/8-7/8=11/8 or 1 3/8
I know its gonna be confusing, but this is all I can do, sorry about that. :)
I don't get what you mean can u pleez give me information what i have to do
Answer
sorry its a parallelogram
Step-by-step explanation:
Our system of equations is:
y = -3x + 9
y = -x - 5
To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.
y = -3x + 9
-x - 5 = -3x + 9
Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.
-x - 5 = -3x + 9
2x - 5 = 9
2x = 14
Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.
x = 7
Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.
y = -3x + 9
y = -3(7) + 9
To simplify, we must multiply through the parentheses and combine like terms by addition.
y = -21 + 9
y = -12
Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).
Hope this helps!
Given:
The inequality is
To find:
The solution of the given inequality.
Solution:
We have,
Isolate the variables terms on the left side.
Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.
Therefore, the correct option is D.
