Rosa works due north of home. Her husband Juan works due east. They leave for work at the same time. By the time Rosa is 7 miles
polet [3.4K]
<span>This is a right triangle problem. c^2 = a^2 + b^2
Let b = 7 mi (Rosa's distance from home)
Let a = the east leg (Juan's distance from home
(a+1) = c (hypotenuse, distance between them)

(a+1)^2 = a^2 + 7^2

FOIL (a+1)(a+1)
a^2 + 2a + 1 = a^2 + 49

Combine like terms
a^2 - a^2 + 2a = 49 - 1
2a = 48
a = 

<span>a = 24 mi, Juan's distance from home

Which graph represents the function f(x) = 2 x – 1 + 2?
tatuchka [14]

Answer:

The graph is positive and would have a y intercept of 1 and a slope of 2 which means choose a point on the graph and add 2 to the y and 1 to the x and you should be at the next point on the line.

Step-by-step explanation:

y=mx+b

f(x)=y

m = slope

b = y intercept

First you need to make it look like y=mx+b

y = 2x - 1 + 2

y = 2x + 1

Now we can say,

m = 2

b = 1

or,

Slope = \frac{2}{1}

y intercept = 1

Slope (m) = \frac{rise}{run}

So the numerator is the value your are going to go up or down along the graph and the denominator is the value of how far you are going to go left or right along the graph. If the slope is positive then the graph is inclining. If the slope is negative, the graph is declining.
