1. Identify the form of each equation. a. 5x + 4y = 8
c. y = 3x + 6

3. Rewrite each equation in standard form.
y - 2 = - (x + 7 )

5. y - 4 = 7/3(x - 3)

Write each equation in standard form.
7. Slope is - 2, and (4, 3) is on the line.

11. Slope = - 3/2, and (2,3) is on the line.

13. (6, 11) and (5, 9) are on the line.

i believe the answer to be 48

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

i don't think there is enough
