Two points on slide are (0, 80), (5, 40).
Step-by-step explanation:
The graph shows the side view of a waterslide and its dimensions are in feet.
First to find (0, ___) and then to find (____, 40).
In the first point <em>x</em>-coordinate is 0 and <em>y</em>-coordinate for the corresponding <em>x</em>-coordinate is 80.
In the second point <em>y</em>-coordinate is 40 and the <em>x</em>-coordinate for the corresponding <em>y</em>-coordinate is 5.
So, the two points are (0, 80), (5, 40).
Answer:
(-5 1/9, -4)
Step-by-step explanation:
Add the equations
5y=-20
y=-4
-9x+8(-4)=22
-9x-32=22
-9x=46
x= - 5 1/9
To do that is by the number 12 and is 12. and the 5 tenth is . 5 then put them together equals 12.5
For this case we can define the following variables:
x: shirt
y: jeans
We write the following system of equations:
12x + 28y = 3900
8.4x + 35y = 3885
We solve the system of equations:
x = 150
y = 75
Note: see attached image for the solution of the system:
