If function / is defined by f(x) = x2 - 2x + 6

Mathematics
1 answer:
salantis [7]4 years ago
4 0

Answer:

21

Step-by-step explanation:

Start with the inside first.

The inside is g(3).

g(3) can be found by using function, g.

g(x)=3x-4 so g(3)=3(3)-4=9-4=5.

So now we have that:

f(g(3))

f(5)

We can find f(5) by replacing x in the expression x^2-2x+6 with 5:

(5)^2-2(5)+6

25-10+6

15+6

21

This means f(g(3))=f(5)=21

28. the second and third one

29. 687.50 dollars

Step-by-step explanation:

2.49(2) + 1.79(2) + 0.89(4) = 12.12 no

2.49(3) + 1.79(2) = 11.05 yes

2.49(2) + 1.79(3) + 0.89 = 11.24 yes

2.49(4) + 1.79 + 0.89 = 12.64 no


area = length times width

a = 6.25 times 5

a = 31.25 square feet

31.25(22) = 687.50

Rearrange the equation so m is the independent variable.<br> -2m-5n=7m-3n<br> n=___
Aneli [31]
<h2>Answer:</h2>

The equation is given by:

        n=\dfrac{-9}{2}m

<h2>Step-by-step explanation:</h2>

We are given a equation in terms of the variable m and variable n as follows:

-2m-5n=7m-3n

Now, we are asked to find the equation in terms of m i.e. we have to consider m as independent variable and n as dependent variable since it's value is to be expressed in terms of m.

Now, we add 5n on both the sides of the equation to get:

-2m=7m-3n+5n\\\\i.e.\\\\-2m=7m+2n

Now, we subtract 7m from both the sides of the equation to get:

-2m-7n=2n\\\\i.e.\\\\2n=-9m\\\\n=\dfrac{-9}{2}m

11. The x-intercept of the line 2x + 3y – 36 = 0 is:
lara31 [8.8K]

Answer:

(18,0)

Step-by-step explanation:

2x + 3y – 36 = 0

The x intercept is when y = 0

Solve for x

2x + 3*0 – 36 = 0

2x +0 -36 = 0

2x -36 =0

Add 36 to each side

2x-36+36 = 36

2x = 36

Divide each side by 2

2x/2 = 36/2

x = 18
