Answer:
27 < 5*n +7
n<4
Step-by-step explanation:
Twenty-seven is smaller than five times a number increased by seven
Increase means add
27 < 5*n +7
Subtract 7 from each side
27-7 <5n+7-7
20 < 5n
Divide by 5
20/5 < 5n/5
4 <n

Step-by-step explanation:
Answer:
$44,000
Step-by-step explanation:
The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:
x*0.09= 4,050
Now, you can isolate x to find her salary this year:
x=4,050/0.09= 45,000
Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:
45,000-1,000= 44,000
According to this, the answer is that her salary in the previous year was $44,000.
4x-1=9x-2
Add 1 to both sides
4x= 9x-1
Subtract 9x from both sides
-5x=-1
Divide both sides by -5
X=-1/-5
What is the slope? We need the slope to find y
