Answer:
a = -6
Step-by-step explanation:
-5a-9+a=15
Combine like terms
-5a+a -9 = 15
-4a -9 = 15
Add 9 to each side
-4a -9+9 = 15+9
-4a = 24
Divide by -4
-4a/-4 = 24/-4
a = -6
22.99*0.05=x
22.99-x= discounted price
Erin took two test. First test saying that she has 70% risk of heart attack(which means 30% chance of not have). The second test saying she has 67% chance of not have a heart attack.
Then, the probability of Erin will not have attack would be: 30%*67%= 20.1% = 0.201
Answer:
x=-3
Step-by-step explanation:
you first distribute -2 then add 6.2 to both sides of the equation the finnaly divide by -3.4 to both side then you will get x
(-2)1.7x+(-2)3.1`
-3.4x-6.2=4
+6.2 +6.2
-3.4x=10.2
-3.4x/-3.4= 10.2/-3.4
x=-3
Given the line, we have points (0,4),(1,3), (2,2), (3,1) and (4,0)
Hence, y= 4-x
