Answer:
f(x)=4x
Step-by-step explanation:
In order to make the graph of f(x)= 4x we will find out few coordinates first and then plot them on the graph. In order to find the coordinates we will find the values of f(x) for random values of x .
Let us see:
x=1 ; f(x) = 4(1) = 4
x=2 ; f(x) = 4(2)=8
x=0 ; f(x) = 4(0)=0
x=-1 ; f(x)= 4(-1) = -4
x=-2 ; f(x)=4(-2)= -8
Hence our coordinates are
(-2,-8) ; (-1,-4) ; (0,0) ; (1,4) ; (2,8)
Now we plot those coordinates on x - y plane and join them to make our line. Please see the graph in the attachment.
Answer:
x = 9
y = 6
Step-by-step explanation:
x / 12 = 6 / 8
x = 6/8 * 12 = 9
(y-4) / 4 = 3 / 6
y - 4 = 3/6 * 4 = 2
y = 6

Answer:
Step-by-step explanation:
Step 3:
Let LM = x
OK = KP = 12 units [Radii of circle K]
LN = LP = 8 units [Radii of circle L]
Therefore, KL = KP + PL
KL = 12 + 8
= 20 units
Step 4:
Since, ΔKOM and ΔLNM are the similar triangles,
By the property of two similar triangles, corresponding sides of these similar triangles will be proportional.
![\frac{OK}{NL}=\frac{KM}{LM}](https://tex.z-dn.net/?f=%5Cfrac%7BOK%7D%7BNL%7D%3D%5Cfrac%7BKM%7D%7BLM%7D)
![\frac{12}{8}=\frac{x+20}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B8%7D%3D%5Cfrac%7Bx%2B20%7D%7Bx%7D)
12x = 8(x + 20) [By cross multiplication]
12x = 8x + 160
12x - 8x = 160
4x = 160
x = 40
