Answer:
2.50
Step-by-step explanation:
4.50 divided by 9 is .50 5 times .50 is 2.50
Answer:
Step-by-step explanation:
Answer:
y = 2x + 75
when x = 0, y = 75
when x = 11, y = 97
when x = 20.25, y = 115.5
when x = 58, y = 191
Step-by-step explanation:
To get the total number of pages she has read, y, after x minutes have elapsed. We will have to go by general form of equation which says
y = mx + b where m is the rate of change or simply the slope, which is 2 pages/minute. and y-intercept will be the number pages she has already read. Our equation will now be y = 2x + 75
The next step is to start substituting the numbers in to the equation
When X = 0
y = 2(0) + 75 = 75
when x = 11
y = 2(11) + 75 = 97
when x = 20.25
y = 2(20.25) + 75 = 115.5
when x = 58
y = 2(58) + 75 = 191
when x = 0, y = 75
when x = 11, y = 97
when x = 20.25, y = 115.5
when x = 58, y = 191
Answer:
The lines are
i) y=-x+6
ii) y=2x-3
The solution of the system of equations is found by equalizing the 2 equations:
-x+6=2x-3
-2x-x=-6-3
-3x=-9
x=-9/(-3)=3
substitute x=3 in either i) or ii):
i) y=-3+6=3
ii) y=2(3)-3=6-3=3
(the result is the same, so checking one is enough)
This means that the point (3, 3) is a point which is in both lines, so a solution to the system.
In graphs, this means that the lines intersect at (3, 3) ONLY
Answer: The graph where the lines intersect at (3, 3)
Answer:
B. Commutative
Step-by-step explanation:
Commutative The order in which the operands are taken does not affect their image under the operation.
I belive this is the answer!
