X^2 + 8x + 7 = 0
x^2 + 7x + x + 7 = 0
x(x + 7) + 1(x + 7) = 0
(x + 7) (x + 1) = 0

x = -7 or x = -1

Lets convert

1mile=5280ft
1h=3600s

$\\ \rm\longmapsto 1mph$

$\\ \rm\longmapsto \dfrac{5280}{3600}ft/s$

$\\ \rm\longmapsto 1.46ft/s$

If rounded

$\\ \rm\longmapsto 1.5ft/s$

Write an equation for the proportional relationship. Let X represent a length measured in meters and y represent the same length

anzhelika [568]

Answer:

$y=100x$

Step-by-step explanation:

Given that $x$ is the length measured in meters and

$y$ represents the same length measured in centimeters.

Let us first have a look at the relationship between meters and centimeters units of length.

1 unit of length in meters = 100 units of length in centimeters

Therefore, it can be said that:

2 units of length in meters = 200 units of length in centimeters

3 units of length in meters = 300 units of length in centimeters

4 units of length in meters = 400 units of length in centimeters

$x$ units of length in meters = 100 $x$ units of length in centimeters

It is given that $y$ is the length in centimeters.

Therefore, the <em>proportional equation</em> can be written as:

$y=100x$
