The exponential function y= a(b)^x passes through the points (3,25) and (8,10). Which of the following is closest to the value o
Yuki888 [10]

If the exponential function y=ab^x passes through the points (3,25) and (8,10), the value of b is 0.833

The given exponential equation is:

y=ab^x

The function passes through the points (3, 25) and (8, 10)

Substitute x = 3 and y = 25 into the function y=ab^x

25=ab^3............................(1)

Substitute x = 8 and y = 10 into the function y=ab^x

10=ab^8.............................(2)

Divide equation (2) by equation (1)

\frac{10}{25}=\frac{ab^8}{ab^3}  \\\\0.4=b^5\\\\b=0.4^\frac{1}{5} \\\\b=0.4^{0.2}\\\\b=0.833

Therefore, if the exponential function y=ab^x passes through the points (3,25) and (8,10), the value of b is 0.833

Plssss help with all thiss​
allsm [11]

Step-by-step explanation:

8, 12(3-x)=48

36-12x=48

-12x=48-36

-12x=12 both side divideos by -12

-12x/-12=12/-12

x= 1

9, x/7=4.5 cris cross

x=31.5

10,5(x-3)=45

5x-15=45

5x=45+15

5x=60 both side divided by 5

5x/5=60/5

x=12

11,-3(x-3)=45

-3x+3=45

-3x=45-3

-3x=42 both side divided by -3

-3x/-3=42/-3

x=14

12,14y-8=13

14y=13+8

14y=21 both side divided by 14

14y/14=21/14

y=1.5

13,3m=5m-8/5

3m-5m=-8/5

-2m=-8/5 cris cross

-10m=-8 both side divided by -10

-10m/-10=-8/-10

x=0.8
