Answer:
Step-by-step explanation:
Two of the four given equations have a y-intercept of (0, -4). Eliminate the remaining two. Next, notice that the shaded area is ON or BELOW the solid line. These characteristics correspond to
y ≤ (1/3)x - 4
Answer:
9x + 14
Step-by-step explanation:
You need to add like terms. Add your x's together and your constants together:
5x + 4x + 6 + 8
9x + 14
Answer:
0.206 is rational
Step-by-step explanation:
A+b=-7
ab=-15
a=-7-b
b(-7-b)=-15
a=-7-b
-b^2-7b+15=0
a=-7-b
b^2+7b-15=0
a=-7-b
b=(-7±sqrt(109))/2
1)
a=-7-b
b=(-7+sqrt(109))/2
b=(-7+sqrt(109))/2
a=-7+3.5-sqrt(109)/2
b=(-7+sqrt(109))/2
a=-3.5-sqrt(109)/2
2)
a=-7-b
b=(-7-sqrt(109))/2
b=(-7-sqrt(109))/2
a=-7+3.5+sqrt(109)/2
b=(-7-sqrt(109))/2
a=-3.5+sqrt(109)/2
