\qquad \tt \rightarrow \: (f - g)(x)

\qquad \tt \rightarrow \: f(x) - g(x)

Simple procedure :

\qquad \tt \rightarrow \: 3x - 1 - (x + 2)

\qquad \tt \rightarrow \: 3x - 1 - x - 2

\qquad \tt \rightarrow \: 3x - x - 1 - 2

Need answer for this.
goblinko [34]

Answer:

The equation of the line is y = (5/2)x + 5.

Step-by-step explanation:

When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :

y = (5/2)x + b

let x = -2, y = 0,

0 = (5/2)(-2) + b

0 = -5 + b

b = 5

Answer:

The area of the shaded figure is:

  • <u>20 units^2</u>

Step-by-step explanation:

To obtain the area of the shaded figure, first, you must calculate this as a rectangle, with the measurements: wide (4 units), and long (6 units):

  • Area of a rectangle = long * wide
  • Area of a rectangle = 6 * 4
  • Area of a rectangle = 24 units^2

How the figure isn't a rectangle, you must subtract the triangle on the top, so, now we calculate the area of that triangle with measurements: wide (4 units), and height (2 units):

  • Area of a triangle = \frac{wide*height}{2}
  • Area of a triangle = \frac{4*2}{2}
  • Area of a triangle =\frac{8}{2}
  • Area of a triangle = 4 units^2

In the end, you subtract the area of the triangle to the area of the rectangle, to obtain the area of the shaded figure:

  • Area of the shaded figure = Area of the rectangle - Area of the triangle
  • Area of the shaded figure = 24 units^2 - 4 units^2
  • <u>Area of the shaded figure = 20 units^2</u>

I use the name "units" because the exercise doesn't say if they are feet, inches, or another, but you can replace this in case you need it.

Johnny invested $20,000.A portion returned 5% and another portion returned 8%. The total interest earned on the investment was $
damaskus [11]

Answer:

Amount invested that yielded interest of 5% is $15000 and amount invested that yielded interest of 8% is $5000

Step-by-step explanation:

Johnny invested $20,000

We are told that it consisted of 2 portions because one returned an interest of 5% and the other one 8%

Now, Let x be the amount invested that earned 5% and y be the amount invested that earned 8%

Thus:

x + y = 20000 - - - (eq 1)

The total interest earned on the investment was $1150

Thus;

5%x + 8%y = 1150

This can be rewritten as;

0.05x + 0.08y = 1150 - - -(eq 2)

From eq 1, let's make x the subject.

x = 20000 - y

Putting 20000 - y for x in eq 2 gives;

0.05(20000 - y) + 0.08y = 1150

1000 - 0.05y + 0.08y = 1150

Rearranging, we have;

0.03y = 1150 - 1000

0.03y = 150

y = 150/0.03

y = 5000

Thus,

x = 20000 - 5000

x = 15000

Thus,

Amount invested that yielded 5% is $15000 and amount invested that yielded 8% is $5000
