What is the solution to this equation?
15 - 2x = 7 - 5x

- 2 2/3

Step-by-step explanation:

Step 1:

15 - 2x = 7 - 5x

Step 2:

15 = 7 - 3x

Step 3:

8 = - 3x

Step 4:

3x = - 8

Step 5:

- 8/3 = - 2 2/3

x = - 2 2/3

Hope This Helps :)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
