What is (f−g)(x)? f(x)=x^4−x^2+9 g(x)=x^3+3x^2+12 (f−g)(x)=

wlad13 [49]

Answer:

x^4 -x^3 -4x^2-3

Step-by-step explanation:

f(x)=x^4−x^2+9

g(x)=x^3+3x^2+12

(f−g)(x)= x^4−x^2+9 - (x^3+3x^2+12)

Distribute the minus sign

(f−g)(x)= x^4−x^2+9 - x^3-3x^2-12

I like to line them up vertically

x^4 −x^2+9

- x^3 -3x^2-12

---------------------------

x^4 -x^3 -4x^2-3

Which is an equivalent form of the first equation that when added to second equation eliminates the x terms? 4/5 x-3/5y=18

Fittoniya [83]

Answer:

$-8x + 6y = -180$

Step-by-step explanation:

Given

$\frac{4}{5} x-\frac{3}{5}y=18$

$8x + 12y = 11$

Required

Equivalent form of the first equation that eliminates x when added to the second

To do this, we simply make the coefficients of x to be opposite in both equations.

In the second equation, the coefficient of x is 8.

So, we need to make the coefficient of x -8, in the first equation.

$\frac{4}{5} x-\frac{3}{5}y=18$

Multiply by -10

$-10 * [\frac{4}{5} x-\frac{3}{5}y=18]$

$\frac{-40}{5} x+\frac{30}{5}y=-180$

$-8x + 6y = -180$

When this is added to the first equation, the x terms becomes eliminated

A participant in a medical study walked 10,388 steps per day. If their

JulijaS [17]

Answer:

55.4068881439

Step-by-step explanation:

Lets first find the feet they walk per day, multiply the steps by the feet/step:

$10,388*2.5=25970$

Now lets find the feet/week by multiplying that value by 7:

$25970*7=181790$

Now lets convert the feet to km:

$181790/3281=55.4068881439$

Resulting in approximately 55 kilometers
