Answer:
1. 21/25
2. 72
3. -4
4. Typo?
2I+2w= 33
21+2w=34
5. Dont understand this question withought context
Step-by-step explanation:
1. 84/4 and 100/4 is 21/25
2. 3(6)(-4) miltiplication
3. worry about parenthesis first, a positive plus a negatative goes to minus so 6-4 then multiply 2 times -2 and get -4
4.
2I+2w is 2(10)+2(6.5)
21+2w is 21+2(6.5)
System:
y ≤ -x + 4
y >

x
Notes:
1. inequalities are expressed in slope-intercept form. y = mx + b
2. the second inequality uses the greater than inequality symbol rather than the greater or equal to symbol due to the broken line.
3. All points in the shaded region will satisfy both inequalities. Point outside the shaded region will not satisfy both inequalities.
The answer to that is B it’s 60
