Answer:
-5x + 0y = -11
The y terms are eliminated
Step-by-step explanation:
- 4x – 2y = -2
X - 2y = 9
We want to subtract the second equation from the first
Distribute a minus sign to all the terms in the second equation
- 4x – 2y = -2
X - 2y = 9
= (-5x + 0y = -11)
D is the correct formula that the model represents. Black represents negative values, while white represents positive.
Answer:
y= (1/4)x+2
Explanation:
Comparing y =-4x + 8 to the slope-intercept form y=mx+b
• Slope = -4.
Let the slope of the new line = m
Two lines are perpendicular if the product of their slopes is -1.
Therefore:
The slope of the perpendicular line = 1/4
Since the line passes through the point (8,4), we have:
The equation of the perpendicular line is y= (1/4)x+2
Answer:
-7/20
Step-by-step explanation:
3/10 ÷ -6/7
Copy dot flip
3/10 * -7/6
-21/60
Divide the top and bottom by 3
-7/20
In ordinary arithmetic, the expression has no meaning, as there is no number which, multiplied by 0, gives a (assuming a≠0<span>), and so division by zero is undefined.</span>
