Answer:
Y= 30
Step-by-step explanation:
180-70=110 So now you know what your other two angles add up to.
Take 110 and your two other problems (3y-20) and (y+10)
Substitute y for a random number, as in 30.
Do the math (3(30)-20)
90-20=70 [Now your previous 110 is 40}
Then for the second equation (30+10)= 40
Y=30
Answer: They have 775 miles left to be traveled
Step-by-step explanation:
Miles required to travel for vacation = 1,325 miles
Miles already traveled = Miles driven this week + miles driven today
= 420 miles + 130 miles
-=550 miles
Miles remaining to be covered =Miles required to travel for vacation --- Miles already traveled
= 1,325 miles - 550 miles
= 775 miles
The rule P(x, y)→P'<span>(x+10, y−6),
shifts point P 10 units right and 6 units down.
Point G(-7, 4) under the rule </span>G(x, y)→G'(x+10, y−6) is translated as follows:
<span>
P (-7+4)</span>→P' (-7+10, 4−6)= P'(3, -2)
<span>
Answer: P'( 3, -2)

Answer:
Table 3
Step-by-step explanation:
In a proportional relationship there must be a constant rate of change.
The first table:
6-5 / 9-7 = 1/2
5-3 / 7-4 = 2/3
These are not equal so it is not proportional.
The second table:
10-8 / 150-120 =2/30
8-5 / 120-75 = 3/45
These are not equal so it is not proportional
The third table:
10-8 / 12-10 =2/2 = 1
8-6 / 10-8 =2/2 = 1
These are equal so this table is proportional.
