Question

Complete the table below to solve the equation 2.5x – 10.5 = 64(0.5x).

x f(x) = 2.5x – 10.5 g(x) = 64(0.5x)
2
3
4
5
6

Just imagine like a table it wouldn't copy and paste.

Answer 1

I'm just going to solve that equation:
2.5x – 10.5 = 64(0.5x)
2.5x - 10.5 = 32x
2.5x - 32x = 10.5
-29.5x = 10.5
x = -10.5/29.5

Answer 2

there are x values so replace x by its value and solve for y
f(x) and g(x) is same as y

Answer 3

for example first one is 2
so replace x by 2 and then solve for y

Answer 4

O OK that makes more since.

Answer 5

okays so when x =2 y = what ?

Answer 6

-5.5

Answer 7

?? @Nnesha

Answer 9

yes right f(2) = -5.5
now replace x by 2 in this equation g(x) = 64(.5x)
solve for g(2)

Answer 10

g(2)=16

Answer 11

`16 how did you get that ?

Answer 12

I'm sorry the g(x) equation the x is suppose to be a exponent

Answer 13

ohh okay so yes that's right
now repeat the pattern!

Answer 14

OK thanks so much

Answer 15

my pleasure :)
