IV is the most useful (even though all will work)
To find the y-intercept, take x=0 and substitute it into the equations.

We can see that if x=0, you can very easily observe that option IV reduces to
y = 0 + 0 - 24 = -24.
Hence (0,-24) is the y-intercept

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]

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 =

a = 24 mi, Juan's distance from home

Find the value of f(3) for the function. f(x) = -2(x + 3)

BabaBlast [244]

Answer:

-2(3+3) = -12

Step-by-step explanation:

f(x) is telling you to substitute all the x values into the equation. The f(x) of the function is 3, telling you to plug in 3 in the equation. This leads to -2(6) = -12.
