That is called an improper fraction.You multiply the whole numbers by the denominator and then add what is left over to get the improper fraction.

Find the equation of all tangent lines having slope of -1 that are tangent to the curve y=(9)/(x+1)

fredd [130]

Answer:

$f(x)=\frac9{x+1}\\ f'(x)=-\frac9{(x+1)^2}\\ f'(x)=-1\ \iff\ -\frac9{(x+1)^2}=-1\ \to \ \frac9{(x+1)^2}=1\ \to \ (x+1)^2=9\\ |x+1|=3\ \to \ x+1=3\ \vee\ x+1=-3\\ x_1=2\ \vee\ x_2=-4\\ f(x_1)=f(2)=\frac9{2+1}=3\\ f(x_2)=f(-4)=\frac9{-4+1}=-3$

First tangent line:

$y=f'(x_1)\cdot (x-x_1)+f(x_1)\ \to \ y=-1(x-2)+3\ \to \ y=-x+5$

Second tangent line:

$y=f'(x_2)\cdot (x-x_2)+f(x_2)\ \to \ y=-1(x+4)-3\ \to \ y=-x-7$

Notice: slope of -1 means that both $f'(x_1), \ f'(x_2)$ are equal to -1, so $f'(x_1)=-1 \ and \ f'(x_2)=-1$

Jess shares £60 in the ratio 3:4

Nataliya [291]

Answer:

Amount of money share by Jess = £25.70

Another Amount of money share by Jess = £34.3

Step-by-step explanation:

Given:

Amount of money Jess have = £60

Sharing ratio = 3 : 4

Find:

Amount of money share by Jess

Computation:

Sharing amount = Shared ratio / Sum of ratio

Amount of money share by Jess = 60[3/(3+4)]

Amount of money share by Jess = 60[3/(7)]

Amount of money share by Jess = 180 / 7

Amount of money share by Jess = £25.70

Another Amount of money share by Jess = £60 - £25.70

Another Amount of money share by Jess = £34.3

20% of the rose Annette picked from a rose garden were red if she picked 10 red roses how many roses did she pick from the garde

horrorfan [7]

Answer:

Option A

Annette picked 50 roses from the garden

Step-by-step explanation:

Let us understand the problem, designating letters to represent unknown quantities.

Let the total number of roses = x

20% of the roses were red means that 20% of x = red

Since the number of red roses = 10,

we will have that 20% of x = 10

mathematically, we will have

$\frac{20}{100} \times x = 10\\x= \frac{1000}{20}= 50$

hence, Annette picked 50 roses from the garden
