Answer:

f(e - 9) = 8e - 67

Step-by-step explanation:

To evaluate f(e - 9) substitute x = e - 9 into f(x)

f(e - 9) = 8(e - 9) + 5 = 8e - 72 + 5 = 8e - 67

Find each unknown angle measurement.

Alex Ar [27]

Answer:

angle(2) = 118 degree

angle(3) = 118 degree

angle(4) = 62 degree

Step-by-step explanation:

To find angle 2 :

$62 + angle{2} = 180 \\ angle{2} = 180 - 62 = 118 \: degree$

The rule (head to head):

angle(2) = angle(3) = 118 degree

And the last one is angle(4) which is the same thing:

angle(4) = angle(1) = 62 degree

8y-2d=0 5y+4d=26 1/4

Anit [1.1K]

Answer:

y = 1

d = 4

Step-by-step explanation:

8y - 2d = 0 ---------------(I)

5y + 4d = 26 1/4

5y + 4d = 105/4 ------------------(II)

(I)*2 16y - 4d = 0

(II) 5y + 4d = 105/4 {add (I) &(II)}

21y = 105/4

$y = \frac{105}{5*21}\\\\y=\frac{105}{105}\\\\y = 1$

Substitute y =1 in equation (I)

8*1 - 2d = 0

8 - 2d = 0

-2d = -8

d = -8/-2

d = 4

prisoha [69]

Answer:

No solution

Step-by-step explanation:

3 x + y = 4 (1)

− 3 x − y = − 8 (2)

Add (1) and (2)

0 + 0 = -4

0 = -4 is a false statement

So, no solution
