Answer:
y=-2x-2.
Step-by-step explanation:
m= -2 for perpendicular line
m= y2-y1/x2-x1
-2 = y-4/x+3
y=-2x-2
Answer:
all nonnegative real numbers
Step-by-step explanation:
all nonnegative real numbers give us all nonnegative integers
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:
(0, - 3) and (4, 5)
Step-by-step explanation:
Given the 2 equations
y = x² - 2x - 3 → (1)
y = 2x - 3 → (2)
Substitute y = x² - 2x - 3 into (2)
x² - 2x - 3 = 2x - 3 ← subtract 2x - 3 from both sides
x² - 4x = 0 ← in standard form
x(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x = 0
x - 4 = 0 ⇒ x = 4
Substitute these values into (2) for corresponding values of y
x = 0 → y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )
x = 4 → y = 2(4) - 3 = 8 - 3 = 5 ⇒ (4, 5 )
Please, one problem at a time. Haven't you started any of these?
What is a+b? Write out a and b, one over the other, and then combine like terms:
1i + 4j
-4i - j
-----------
-3i + 3j (answer to "a+b").
