Answer:
Solution set = {(-1,-2/5)]
Step-by-step explanation:
64p=-16+8p-40p²
64p-8p=-16-40p²
56p+16+40p²=0
40p²+56p+16=0
8(5p² +7p+2)=0
5p²+5p+2p+2=0
5p(p+1) +2(p+1)=0
(p+1)(5p+2)=0
p+1=0; 5p+2=0
p=-1; p=-2/5
Y=5x+3. because your y axis is moved
Answer: Sandra's salary in the previous year was $48,000
Step-by-step explanation:
Hi, the expression given is missing the $2000 more that she earns this year.
0.14 (x +2000) =7000
Where:
- <em>x is Sandra's salary in the previous year.
</em>
- <em>0.14 is the decimal form of 14% (14/100=0.14)
</em>
Solving for x :
0.14(x) +0.14 (2000) =7000
0.14x +280 =7000
0.14 x = 7000-280
0.14x = 6720
x = 6720/0.14
x=48,000
Sandra's salary in the previous year was $48,000
