Write an equation if the line that is parallel to y=2x-5 and passes through (-4,2)

Step-by-step explanation:

y=2x-5

From y=mx+c

Comparing the equation

M=2.

For parallelism

M₁=M₂

y-y₁=m(x-x₁) equation of a line passing through a point

point (-4,2) are x₁ and y₁ respectively

y-2=2(x-(-4))

y-2=2(x+4)

y-2=2x+8

y=2x+8+2

y=2x+10

but which class are u may know that first

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
