Answer:

a = 2  

b = 4

The equation is ⇒ y=2(4)^{x}

Step-by-step explanation:

∵ It is an exponential Regression

∴ y = ab^{x} where a ≠ 0

∵ x = 0 ⇒ y = 2

∴ 2 = ab^{0} ⇒ 2 = a(1) (where b^0 = 1)

∴ a = 2

∵ x = 1 ⇒ y = 8

∴ 8 = 2(b)^1 ⇒ 8 = 2b ⇒ b = 8 ÷ 2 = 4

∴  b = 4

∴ The equation is ⇒ y = 2(4)^{x}

Which ordered pair is in the inverse of<br> the relation given by p?y + 5y= 0?
natta225 [31]

Remember that an ordered pair is of the form (x, y), then the ordered pairs on the inverse of the relation are (x, -x/5).

<h3>Which ordered pair is in the inverse of the relation given?</h3>

Assuming the given relation is:

y + 5x = 0

We can rewrite it to:

y = -5x

Then the inverse will be a function g(x) such that:

y = -5*g(x) = x

Solving for g(x):

g(x) = (-x/5).

Then the inverse of the relation is:

y = -x/5

Remember that an ordered pair is of the form (x, y), then the ordered pairs on the inverse of the relation are (x, -x/5).

NEED HELP QUICK! u dont have to give me the answer, giving me the equation to use would be just fine and greatly appreciated!
kykrilka [37]

So for this we will be writing two equations: one representing rachel and the other with oliver. I'll be using the slope-intercept form, which is y = mx + b (m = slope, b = y-intercept). The slope is considered the constant rate of the equation, which in this case its "3 bracelets an hour" and "2 bracelets an hour". The y-intercept is considered the initial value, which in this case with Oliver "he already has 5 bracelets." Using the info above, these are our 2 equations:

Let x = # of hours and y = total bracelets

y = 3x\\ y=2x+5

With these equations, thanks to the transitive property (if a = b and a = c then b = c) she can set 3x and 2x + 5 equal to each other and solve for the number of hours it would take for them to have the same amount of bracelets.
