Y=-2x-21 determine the intercepts of the line (,) (,) ASAPPPP
Nesterboy [21]

Answer:

x intercept (10.5,0)

y intercept (0, -21)

Step-by-step explanation:

y=-2x-21

there are two intercept for a line

x intercept, the point of given equation of  line which lies on x axis.

For x intercept corodinate of y is o

Thus, value x intercept is form (x,0)

putting these value in y=-2x-21, we find x intercept

0=-2x-21

2x = 21

x = 21/2 = 10.5

Thus, x intercept (10.5,0)

Y intercept, the point of given equation of  line which lies on y axis.

For Y intercept coordinate of x is o

Thus, value y intercept is form (0,y)

putting these value in y=-2x-21, we find y intercept

y = -2*0 -21

y = -21

Thus, y intercept (0, -21)

F(n) = -11 + 22(n = 1)<br> Complete the recursive formula of f(n).<br> f(1) =<br> f(n) = f(n - 1)+
Maslowich

Answer:

f(n)=f(n-1)+22.

Step-by-step explanation:

Note: In the given function it should be (n-1) instead of (n=1).

Consider the given function is

f(n)=-11+22(n-1)

It is the explicit form of an A.P.

For n=1,

f(1)=-11+22(1-1)=-11+0=-11

For n=2,

f(2)=-11+22(2-1)=-11+22=11

Common difference is  

d=a_2-a_1=11-(-11)=11+11=22

The recursive formula of an A.P. is

f(n)=f(n-1)+d

Substitute d=22 in the above formula.

f(n)=f(n-1)+(22)

f(n)=f(n-1)+22

Therefore, required recursive formula is f(n)=f(n-1)+22.
