$f(x)=x+3;\ g(x)=x^2-2\\\\\left(\dfrac{f}{g}\right)(-1)-g(3)=?\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{f(x)}{g(x)}\\\\g(3)=3^2-2=9-2=7\\\\f(-1)=-1+3=2\\\\g(-1)=(-1)^2-2=1-2=-1\\\\\left(\dfrac{f}{g}\right)(-1)-g(3)=\dfrac{2}{-1}-7=-2-7=-9$

Answer: x = 16

Step-by-step explanation:

Let G be Gracie's shells

Let x be Mary's shells

Let N be Nancy's shells

G = 1.25x + 5

N = 1.5x + 1

G = N

1.25x + 5 = 1.5x + 1

4 = 0.25x

Multiply both sides by 4

x = 16

Find the distance to the nearest tenth

grin007 [14]

Answer:

d=11.2

Step-by-step explanation:

$d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} \\ }$

$d=\sqrt{(6-(-4)^{2}+(-3-2)^{2} }$

$d=\sqrt{10^{2}+5^{2} }$

$d=\sqrt{100+25}$

$d=\sqrt{125}$

$d=11.18$

$d=11.2$

A rectangle has a perimeter of 50 centimeters. If the width of the rectangle is 10 centimeters, what is its length?

olga2289 [7]

Answer:

15 cm

Step-by-step explanation:

The perimeter of a rectangle is 2(L + W), where L is length of the rectangle and W is the width.

If we plug in 10 for W, we get this:

2L + 2(10) = 50 <-- the perimeter

2L + 20 = 50

2L = 30

Original price: $150; Markdown:40%(show work please)

zepelin [54]

Original price is $150 so you times 150 by 0.40
150 x 0.40 = 60
So you take the $150 and you subtract $60 from $150
150 - 60 = 90
So the answer is $90

If a and b are positive numbers such that 2b=3a, what's the value of ((a+b)/b)? I know you can plug in numbers for this, but i'm

yarga [219]

$\displaystyle 2b =3a \Rightarrow a= \frac{2b}{3} \\\\ \frac{a+b}{b}= \frac{ \frac{5b}{3} }{b} = \frac{5b}{3b} = \frac{5}{3} =1 \frac{2}{3}$
