Answer:

x = 4

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n , then x = $b^{n}$

Given

$log_{7}$ (5 + 11x) = 2 , then

5 + 11x = 7² = 49 ( subtract 5 from both sides )

11x = 44 ( divide both sides by 11 )

x = 4

Answer: The exponential function would be

Step-by-step explanation:

Since we have given that

We have points (0,15) and (2,24)

First we take when x= 0, y = 15.

So, our equation becomes,

and we take when x = 2 and y = 240

So, the exponential function would be

Answer:

3.v-4=6

v=6+4

v=10

6.y-32=-1

y=-1+32

y=31

9.-1=t+(-19)

-1=t-19

-1+19=t

18=t

12.u+(-5)=-15

u-5=-15

u=-15+5

u=-10

15.47=w-(-8)

47=w+8

47-8=w

39=w

21.18f=-216

f=-216/18

f=-12

24.96=-24a

96/-24=a

-4=a

27.-84=d/3

-84*3=d

-252=d

30.81=1/6*n

81=n/6

81*6=n

486=n

33.5/9*p=-10

5p=-10*9

p=-90/5

p=-18

Please help!! <br>what are the x-intercepts of this equation.

padilas [110]

The x intercepts are -2 and 5. First, you factor the equation and get (2x+4)(2x-10), then solve for the x's. If you have more problems like this, there's a great online calculator that can help with graphing. www.symbolab.com. It tells you the intercepts if you plug in the equations. Hope this helps!
