If f(x)=x^2- 4 and g(x)=x^2 plus 2 x,

gregori [183]

Answer:

$\huge\boxed{(f-g)\left(-\dfrac{1}{3}\right)=-3\dfrac{1}{3}}$

Step-by-step explanation:

$\text{We have}:\\\\f(x)=x^2-4\ \text{and}\ g(x)=x^2+2x\\\\(f-g)(x)=f(x)-g(x)\\\\\text{therefore}\\\\(f-g)(x)=(x^2-4)-(x^2+2x)=x^2-4-x^2-2x\\\\=(x^2-x^2)-2x-4=-2x-4\\\\(f-g)\left(-\dfrac{1}{3}\right)\to\text{put}\ x=-\dfrac{1}{3}\ \text{to the equation of the function}\ (f-g)(x):\\\\(f-g)\left(-\dfrac{1}{3}\right)=-2\left(-\dfrac{1}{3}\right)-4=\dfrac{2}{3}-4=-3\dfrac{1}{3}$

Please show your work

HACTEHA [7]

250 = 167.93 + x

[She needs $250, she has $167.93, and she needs x more. x represents the amount of money she still needs in order to get 250]

250 = 167.93 + x Subtract 167.93 on both sides

250 - 167.93 = 167.93 + x - 167.93

250 - 167.93 = x

82.07 = x

She needs $82.07 more

Or you could have done:

250 - 167.93 = 82.07

I need help finding the measure to each angle<br>

cestrela7 [59]

Answer:

(15x-2)°+( 7x+4)°=90° --> 15x-2°+7x+4°=90° --> 22x+2°=90° --> 22x=90°-2° --> 22x=88° --> x=88/22 --> x=4.

m/_BAC=(15x-2)°=15×4-2 =58°

m/_CAD=(7x+4)°=7×4+4= 32°.
