F(x)=3x+5 and g(x)=2x+1 value of x

AlekseyPX

You can treat x and 2x+1 just as though they are real numbers.

So f(2x+1) = 3(2x+1) - 5 = 6x + 3 - 5 = 6x - 2

In the above, I made use of something called the distributive law which says that if a,b and c are real numbers, then a(b+c) = ab + ac.

Answer:

AREA = 4,850

Step-by-step explanation:

split into two pieces

formula for triangles- base x height divided by 2

20 x 50 = 100 / 2 = 50

(130 - 50 = 80)

80 x 120 = 9,600 / 2 = 4,800

add...

4,800 + 50 = 4,850

Someone please help me with this algebra problem

nevsk [136]

Answer:

$110

Step-by-step explanation:

We are looking for the decrease in money per desk purchased. Because the x-axis is the number of desks purchased, what we have to find is the (opposite) of the slope. The formula to represent slope can be written as:

$\frac{y_{2} -y_{1} }{x_{2}- x_{1} }$

We can substitute the points given, (2, 480) and (5, 150) and simplify:

$\frac{150-480}{5-2} =\frac{-330}{3} = -110$

We would multiply by -1 because we are asking for the decrease, and negative increase is decrease. -1 * -110, gives us $110

Evaluate the polynomial 6x - y for x= -3 and Y=2. A.15 B. -20 C.4 D.-16

ra1l [238]

I think the answer is B.
6(-3)=-18, and y=2
so 6x-y=-18-2=-20
