Answer=9
To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.
x+-4=5
x*-4=-36
9 fits the parameters for both of these
9+-4=9
9-4=5
5=5
9*-4=36
36=36
Answer:

Step-by-step explanation:
We are given the line y=2x+8. It is in slope-intercept form or y= mx+b, where m is the slope and b is the y-intercept.
The slope of the line is 2.
We want to find the equation that is perpendicular. Perpendicular lines have negative reciprocal slopes.
1. Negate
- Negate the slope, or switch the sign
- (+) 2 --> -2
2. Reciprocal
- Flip the numerator and denominator of the slope.
The perpendicular slope is -1/2, so the correct equation must be B.
Answer:
63% increase.
Step-by-step explanation:
You don't really need to do anything because it's probably a 63% increase as 101 is close to 100 already. If you'd like:


≈
63%
40*4.5 +45= 225
