Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same.
If is perpendicular to each other: the slope should be the reciprocal to each other.
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4
This basically means 3 × h, so the answer is 3h when simplified.
Answer:
1.) q=p-mn
2.) -6
3.) 10
Step-by-step explanation:
1.) add q to both sides you should get q+mn=p. then subtract mn from both sides and you should get q=p-mn.
2.) for 5c+23=c-1 you add 1 on both sides and should get 5c+24=c. Then subtract 5c from both sides and get 24=-4c. divide both sides by -4 and your answer should be -6.
3.) replace each number with their value. 4(2)^2-3. Then solve. 4(2)^2=16, then subtract 3 from 16 and get 13. For the next equation again replace each letter with the given value. 3(2)^2-3(3). 3(2)^2=12 and 3(3)= 9. Subtract 12 and 9 and your answer is 3. Now subtract the first equation answer from the second equations answer and you get 10
