Ksju [112]3 years ago
4 0

Answer:

17. xy + z = 51

18 yz - x = 18

21. 5z + ( y - x ) = 20

22. 5x - ( y2 - 4x ) = -10

23 . x2 + y2 - 10z = 70

24. z3 + ( y2 - 4x ) = 1

25. y + xz / 2

26 .3y + x2 / z = 30

Step-by-step explanation:

17.(6 x 8)+3=

    48+3=51

18.(8 x 3)- 6 =

     24 - 6 = 18

21. 15 + ( 8 - 3 )

      15 + 5=

        20

22 .30 - (64 - 24)=

      30 - 40=

       -10

23. 36 + 64 - 30

      100 - 30

        70

24.  9 + (16 - 24 )=

       9 + -8 =

        1

25. 8 + 48 / 2

      56 / 2

       28

26. 24+ 36/3

      60/3=

       30

What is the equation of the line perpendicular to –x + y = 7 and passing through (-1, -1)?
Vesna [10]
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1

at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c 
c = -1 -1
c = - 2

equation:
y = -x -2
y + x = -2 or - x - y = 2

The population of a pack of wolves is 88. The population is expected to grow at a rate of 2.5% each year.
Dennis_Churaev [7]

Answer:

Option B is correct.

f(t) = 88(1.025)^t represents the population of the pack of wolves after t years

Step-by-step explanation:

The exponential growth function is given by;

f(t) = a(1+r)^t               ......[1]

where

a represented the initial value

r represents the rate(in decimal)

t represents the time in years

As per the given statement: The population of a pack of wolves is 88. Also, the population is expected to grow at a rate of 2.5% each year.

⇒ a = 88 and  r =2.5% = 0.025.

Substituting these values in equation [1], we have;

f(t) = 88(1+0.025)^t

or

f(t) = 88(1.025)^t

Therefore, the population model of the pack of wolves after t years is given by:  f(t) = 88(1.025)^t
