Answer:
Step-by-step explanation:
first we put them in y = mx + b form...then we compare the slopes and the y int's. In y = mx + b form, the slope is in the m position and the y int is in the b position.
2x + 2y = 8
2y = -2x + 8
y = -x + 4......slope here is -1 and y int is 4
3x + y = 8
y = -3x + 8.....slope here is -3 and y int is 8
This system has 1 solution <===
================================
learn this...it helps
* if there are different slopes and different y int, then there is 1 solution
* if there are the same slopes and different y int, then there is no solutions because u have parallel lines
* if there are same slopes and same y int, there is infinite solutions because u have the same line
The first one because it passes the through the origin
The most expensive one is 40 so u dont need to add that one in so add up 18 22 and 35 and you get 75. So he spent $75 at the store.
Answer:
the range is 765
Step-by-step explanation:
to find range you must find the largest and smallest number and subtract
Answer:
1921.68mm^3
Step-by-step explanation:
Given data
H=17 millimeters
R=6 millimeters.
We know that the expression for the volume of cylinder is
V= πr^2h
substitute
V= 3.14*6^2*17
V= 3.14*36*17
V= 1921.68 mm^3
Hence the volume is 1921.68mm^3
