Answer:B
Step-by-step explanation:
simple, there is one point of intersection or where the lines meet
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
Answer:
19000 Pa
Step-by-step explanation:
Factor the following:
35 u v - 5 u - 56 v + 8
Factor terms by grouping. 35 u v - 5 u - 56 v + 8 = (35 u v - 56 v) + (8 - 5 u) = 7 v (5 u - 8) - (5 u - 8):
7 v (5 u - 8) - (5 u - 8)
Factor 5 u - 8 from 7 v (5 u - 8) - (5 u - 8):
Answer: (5 u - 8) (7 v - 1)
2^2 x 5 x 7 =140
^ is used to represent exponent
