Answer:
Step-by-step explanation:
So 8 times what is 5?
8 times x=5
x=0.625
Answer:
estimated gpa: 2.85
Step-by-step explanation:
Evaluate y=0.14x+0.75 at x = 15 (hours):
y = 0.14(15 hours) + 0.75
= 2.1 + 0.75
y = 2.85 = estimated gpa corresponding to 15 houirs of study
Answer:
(x-1)^5 (x+1)
Step-by-step explanation:
2 (x-1)^5 + (x-1)^6
Factor out (x-1)^5
2 (x-1)^5 + (x-1)^5 (x-1)
(x-1)^5( 2 + x-1)
Combine like terms
(x-1)^5 (x+1)
3y = 5x+30 , y+5x = 50
using elimination method ...
3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20
so using one of the original equations..
20 + 5x = 50
5x = 30
x =6
x = 6
y = 20
13+(-12-(-5)
13+(-12+5)
13+(-7)
13-7=6
