Is 2x+4-x linear or non linear?

Mathematics

lawyer [7]2 years ago

Answer:

To determine if an equation is a linear function, it must have the form y = mx + b (in which m is the slope and b is the y-intercept). A nonlinear function will not match this form.

So it is linear.

Find an equation of variation where y varies directly as x and y = 7 when x = 0.5 .

Alisiya [41]

Answer:

y = 14x

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in 7 as y and 0.5 as x, and solve for k:

y = kx

7 = k(0.5)

14 = k

Plug this into the equation:

y = kx

y = 14x

So, the equation of variation is y = 14x

Suppose the a mountain bike that sells for $419 is on sale for 20.5% off.

nata0808 [166]

Regular price: $419
Sale price: (1-0.205)($419) = $333.11

The bike will cost $333.11 before tax. You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be

(1.00 + rate as a decimal fraction)*$333.11.

Example: If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).
