Answer:
3 < x < 17
Step-by-step explanation:
triangle inequality theorem: the sum of any two sides must be greater than the third
7 + 10 > x; x < 17
7 + x > 10; x > 3
Answer:
$20.98
Step-by-step explanation:
2 hours means two of 8.74 which equals 17.48 plus that $3.5 in a day. So she gets $20.98 when she works for 2 hours.

1600<2570-125.5x<2000 subtract 2570 from all terms...
-970<-125.5x<-570 divide all terms by -125.5 (and reverse signs because of division by a negative!)
7.73>x>4.54 and x is months since January, and since months can only be integers...
x=[5,7]
So January + 5, 6, and 7 respectively are the three months that satisfy the equation...
June, July, and August.
Answer:
4+8=12
Step-by-step explanation:
Answer:
when x= -4, y= 2
when x= 6, y =7
Step-by-step explanation:
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2
first we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4-2
then subtraction
y=2
For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps
y = 1/4 (36) - 2
y= 9-2
y= 7
