Answer:
The possible numbers for the blank are 5601, 8452, 93647 etc.
Step-by-step explanation:
Consider the provided information.
Blank divided by 7 is greater than 800
Let say the number should be in blank is x.
Now we need to find the value of x so that it divided by 7 gives a value greater than 800.
This can be written as:
Solve the above inequality for x.
The value of x should be greater than 5600.
We can select any number which is greater than 5600.
The possible choice for the blank are 5601, 8452, 93647 etc.
Note there are infinite number greater than 5600 so you can choose any of them.
Answer:
Here's one way to do it.
Step-by-step explanation:
-24 ÷ (-4)
-24 is the final number on the number line
-4 means you count by 4s on the number line moving backwards.
Answer: +6 (The sign is + because you are still facing forward).
The given pair of lines are not perpendicular.
<h3>What is a line?</h3>The line is a curve showing the shortest distance between 2 points.
5x - 5y = -2 - - - - - (1)
Transform the equation into standard form,
5x + 2 = 5y
y = 5x /5 + 2/5
y = x + 2/5
The slope of equation 1 is and intercept c = 2 / 5
Similarly
x + 2y = 4 - - - - - - - -(2)
Transform it into standard form
y = -x/2 + 4 /2
y = -x / 2 + 2
Slope of the equation 2 = -1 / 2 and intercept c = 2
Slope of line 1 * slope of line 2 = 1 * -1/2 = -1/2
Since the lines are not perpendicular because the pair of lines does not satisfy the property of perpendicular lines i.e
Thus, the given pair of lines are not perpendicular.
