you have to divide 7 by 15 equals .466666666
Answer:
Pencils = 325 ; Pens = 975 ; Markers = 650
Step-by-step explanation:
Let :
Number of Pencils = x
Number of pens = y
Number of markers = z
2 times as many markers as pencils
z = 2x
3 times as many pens as pencils
y = 3x
x + y + z = 1950
Write z and y in terms of x in the equation :
x + 3x + 2x = 1950
6x = 1950
Divide both sides by 6
6x / 6 = 1950 / 6
x = 325
Number of pencils = 325
Pens = 3 * 325 = 975
Markers = 2 * 325 = 650
Pencils = 325 ; Pens = 975 ; Markers = 650
X= 6
5x-10 = 20
5x=20+10
5x=30
x= 6
when x = -9, y = 1
Here, we want to get the value of y when x = -9
To find this, we look at the point x= -9 on the x-axis
After getting this, we trace it to the graph
Looking at the graph, the graph crosses the x-axis at exactly this point
What this mean is that the value of y at that point is 1
Hence, for input -9, output is 1
