Answer:
y < -3 and
2x - 3y ≥ -15
Step-by-step explanation:
y < -3
Take any two points on the bold line
(0 , -5) and (-3 , -7)
Now find the slope for this line and then the equation of the line
Slope =
Slope, point equation,
y - y1 = m(x -x1)
Take any point from the shaded region and plugin the LHS of the equation.
(-6 , -5)
LHS = 2x - 3y
= 2*(-6) -3*(-5)
= -12 + 15
= 3 which is ≥ -15
2x - 3y ≥ -15
Answer:
4X
a+b+c+d
Step-by-step explanation:
Let the total cost = y
If the price of four binders are the same, then each will cost x dollars.
The total cost will be 4X
If the price are not the same, then total cost will be a+b+c+d
While a, b, c and d represent cost for each book.
The answer will be (2) 0 and 9
X^2(x-9)
X=0, and 9
Answer:
ok put into y=mx+b form
2y=60x+120
y=30x+60
so we know 60 is the y-intercept so he is not correct
if u want more:
-60x+2y-120=0 add 60x
2y-120=60x add 120
2y=60x+120 divide by 2
y=30x+60
Hope this helps plz hit the crown :D
X>-6 is what i believe the answer is.
hope this helps!
