Answer:

Ellen invested $60 and Bob invested $140

Step-by-step explanation:

let the two amounts invested by 3x and 7x

(notice 3x : 7x = 3 : 7 )

then 3x + 7x = 200

10x = 200

x = 20

then 3x = 3(20) = 60

and 7x = 7(20) = 140

60+140=200

3y = x - 12<br> Y= 1/3X -4<br> parallel, perpendicular or neither
aliina [53]

Answer:

PARALLEL

Step-by-step explanation:

The second equation, y = (1/3)x - 4, has already been solved for y.  To compare the slopes easily, we need now to solve the first equation for y, obtaining y = (1/3)x - 4.

We see that these two lines have the same slope, m = 1/3, and thus conclude that these lines are PARALLEL.

If f(x) = 4x + 3 and g(x) = 3x, evaluate for X = -1/2
miskamm [114]

Answer:

 f(-\frac{1}{2}) = 1

g(-\frac{1}{2} ) = -\frac{3}{2}

Step-by-step explanation:

Given the function f(x) = 4x + 3 and the function g(x) = 3x, to evaluate for x=-\frac{1}{2}, you need to substitute it into each function.

Then, for the function f(x), when  x=-\frac{1}{2}, you get:

 f(-\frac{1}{2}) = 4(-\frac{1}{2}) + 3

 f(-\frac{1}{2}) = 4(-\frac{1}{2}) + 3

 f(-\frac{1}{2}) = -\frac{4}{2}+ 3

 f(-\frac{1}{2}) = -2 + 3

 f(-\frac{1}{2}) = 1

For the function g(x), when  x=-\frac{1}{2}, you get:

g(-\frac{1}{2} ) = 3(-\frac{1}{2})

 g(-\frac{1}{2} ) = -\frac{3}{2}
