Answer:
1/3x - 6
Step-by-step explanation:
Perpendicular lines have the negative reciprocal slope. This means that you find the slope of the original line which is -3. Then you flip it so it’s -1/3. Lastly you change the sign 1/3. The negative 6 is the y intercept the question asked for.
To calculate 13% of 2120, we multiply by 13/100. 13/100*2120=13*21.2, or 275.6 using basic multiplication.
X^2+7x-7x-49
Simplified = x^2-49
