Answer:
We know that the value of n will be negative.
Step-by-step explanation:
Since 15 is so much larger than 2, we know that the other value on that side would have to be a negative value. Since the coefficient is not negative, we know the variable must be.
To solve this problem, you read the problem backwards and to the opposite of that function.
- if it says double --> divide by 2 22 / 2 = 11
- subtract by 19 --> add 19 11 + 19 =30
- multiply by 5 --> divide 5 30 / 5 = 6
Thus the number that is thought of is 6

Hello!
The equation for slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
We can first find the slope. Perpendicular lines have slopes which are negative reciprocals of each other. This means that the slope of the line you're looking for would be the negative reciprocal of -2/9. The negative reciprocal of -2/9 is 9/2. Therefore, m = 9/2.
Substitute this into the equation. y = 9/2x + b. Now substitute in the point given and solve for b.
y = -4, x = -2
-4 = 9/2 (-2) + b
-4 = -9 + b
b = 5
Therefore, the final equation is y = 9/2x + 5.
Hope this helps!
From the second equation:-
x = 6 - 4y
Substitute this for x in the top equation
