Kyla is hiking. She comes to this marker at a fork in the trail. Which of these gives the same distance to Cascade Falls?
gogolik [260]

Answer:

3.5 miles

Step-by-step explanation:

The actual choices and question is as attached. Since it's shown in a mixed fraction as 3\frac{1}{2} then we convert the number to decimal. \frac {1}{2} will be 1 divided by 2 which is 0.5 hence the distance to Cascade Falls is 3.5 miles

Change the equation 2x - 5y + 4 = 0 into an equivalent equation written in the slope-intercept form
mamaluj [8]

Answer: The equation in slope intercept form is

y = 2x/5 + 4/5

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = y intercept

m represents the slope of the line.

The given equation is expressed as

2x - 5y + 4 = 0

Adding 5y to the left hand side and the right hand side of the equation, it becomes,

2x - 5y + 5y + 4 = 5y

5y = 2x + 4

Dividing the left hand side and the right hand side of the equation by 5, it becomes,

5y/5 = 2x/5 + 4/5

y = 2x/5 + 4/5

Which of the following systems is dependent? x − y = 2 and x + y = −2 x − y = 2 and −2x + 2y = −4 x − y = 2 and 3x − 3y = 2 x −
hram777 [196]
A system is linearly dependent, when multiplying one of the equations by a scalar, you get the other equation.
 We then have the following system of equations:
 x - y = 2

-2x + 2y = -4
 Let's rewrite the system of equations.
 To do this, let's multiply equation 1 by scalar -2:
 -2x - (-2) y = (-2) 2

-2x + 2y = -4
 We observe that we obtain equation 2 of the system.
 Therefore, the system is linearly dependent.
 Answer:
 
the following system is dependent:
 
x - y = 2 and -2x + 2y = -4
