Step-by-step explanation:
To find the inverse , inerchange the variable and slove for Y
Answer:
<h2><u><em>
x = - 14</em></u></h2>
Step-by-step explanation:
-3x – 10 = 32 Help me I need the answer
-3x – 10 = 32
-3x = 32 + 10
-3x = 42
x = 42 :(-3)
x = - 14
-----------------
check
-3 × (-14) - 10 = 32 (remember pemdas)
42 - 10 = 32
32 = 32
the answer is good
Answer:
if i remember it correct it is yes no yes no. Im so sorry if it is wrong.
Step-by-step explanation:
Part A)
y < 2*x
y > 4/5*x
The graph will shade below the line y = 2x (not including the line),
and above the line y = 4/5*x (not including the line).
Where the shaded regions overlap is the solution area.
In the graph, the overlapping region is darkest.
part b) verify that point C and point F satisfy the inequalities
plug in point C and point F separately.
you should get a true statement, each time
part c) if we graph
y < -2x + 2
over the plotted points
lets see what points it covers
The shade region covers points A,B,D
so those are the schools she can attend
Answer:
(3,0), (4,0), (5,0)
on the x-axis at 3, 4 and 5
Step-by-step explanation:
This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")
0=(x-5)(x^2-7x+12)
0=(x-5)(x-3)(x-4)
0=x-5, 0=x-3 & 0=x-4
x=5, x=3, x=4
This is where the graph crosses the x-axis.
