Answer:
a = 3, b = -1
Step-by-step explanation:
a = 5b + 8
a = -10b - 7
5b + 8 = -10b - 7
Add 10b from both sides;
15b + 8 = -7
Subtract 8 from both sides;
15b = -15
Divide both sides by 15;
b = -1
Lets substitute b;
a = 5b + 8
a = 5(-1) + 8
a = -5 + 8
a = 3
-x/4-6>-8
Multiply both sides by 4
-x-24>-32
Move the constant to the right
-x>-32+24
-x>-8
Change the signs
x<8
Answer:
Step-by-step explanation:
the equation line passes through(-3,0)and (0,3) is : y=ax+b
a is the slope a = (3-0)/(0+3) = 1
so : y= x +b calculate b line passes through(-3,0)and (0,3)
x=0 y=3 : 3 = 0+b so b= 3
this equation is : y= x+3
Answer:
5/6
Step-by-step explanation:
3/6 + 1/3 = 3/6 + 2/6 = 5/6
