Use substitution to find out
x=2
y=3
so
3=3(2)-4
3=6-4
3≠2
no, this point does NOT lie on the graph of y=3x-4
Answer:
0.5
Step-by-step explanation:
The average rate of change (m) on the interval [a, b] is ...
m = (f(b) -f(a))/(b -a)
On the interval [-2, 3], the average rate of change is ...
m = (5 -2.5)/(3 -(-2)) = 2.5/5 = 0.5
Its Between C and A For me but I will see what I get! but maybe this would help explain!
y = 2x + 4 is the equation and they want to know what the orderd pair of the point that crosses the y axis is. We don't know what the orderd pair means.
-------------------------
The y-axis contains all the points where x=0.
-----------------------
If y = 2x+4, let x=0 so you can solve for "y":
y = 2*0+4

y = 4</span>
Answer:
Option C
23.08% markup on selling price.
Step-by-step explanation:
Given in the question,
markup percentage on cost price = 30%
To find,
markup percentage on selling price
Markup is the ratio between the cost of a good or service and its selling price.
Let suppose that cost price percentage = 100%
As we know that,
<h3>cost% + markup% = selling%</h3><h3>100% + 30% = 130%</h3>
So percent markup selling price = 30 / 130 x 100
= 23.0769
Hence, 30% markup on cost price = 23.0769% markup on selling price.
Perimeter of rectangle is 8x and Area is 3x^2 + 2x -1..
Lets try to solve out the problem,
Length = 3x-1
Width = x+1
Perimeter = 2(l+b)
Area = l*b
Perimeter= 2 (3x-1 + x+1)
P= 8x
Area = (3x-1) (x+1)
=> 3x(x+1) -1 (x+1)
=> 3x^2 + 3x -x -1
=> 3x^2 + 2x -1.
Hence Perimeter of rectangle is 8x and Area is 3x^2 + 2x -1..
