Answer:

The fraction of the total number of leaves did they collect altogether is $\frac{16}{25}$

Step-by-step explanation:

This question can be solved by a sum of fractions.

Lee collect 24/100 of the tiral number of leaves needed.

Maya collects 4/10 of the total number of leaves needed.

What fraction of the total number of leaves did they collect altogether?

This is the sum of 24/100 and 4/10.

The lesser common multiple between 100 and 10 is 100. So

$\frac{24}{100} + \frac{4}{10} = \frac{24 + 10*4}{1001} = \frac{64}{100}$

We can simplify by four

The fraction of the total number of leaves did they collect altogether is $\frac{16}{25}$

For what value(s) of k will the relation not be a function

skelet666 [1.2K]

We are given two relations

(a)

Relation (R)

$R=[((k-8.3+2.4k),-5),(-\frac{3}{4}k,4)]$

We know that

any relation can not be function when their inputs are same

so, we can set both x-values equal

and then we can solve for k

$k-8.3+2.4k=-\frac{3}{4} k$

$3.4k-8.3=-\frac{3}{4}k$

$3.4k\cdot \:10-8.3\cdot \:10=-\frac{3}{4}k\cdot \:10$

$4k-83=-\frac{15}{2}k$

$34k=-\frac{15}{2}k+83$

$\frac{83}{2}k=83$

$83k=166$

$k=2$ ............Answer

(b)

S = {(2−|k+1| , 4), (−6, 7)}

We know that

any relation can not be function when their inputs are same

so, we can set both x-values equal

and then we can solve for k

$2-|k+1|=-6$

$2-\left|k+1\right|-2=-6-2$

$-\left|k+1\right|=-8$

$\left|k+1\right|=8$

Since, this is absolute function

so, we can break it into two parts

$|f\left(k\right)|=a\quad \Rightarrow \:f\left(k\right)=-a\quad \mathrm{or}\quad \:f\left(k\right)=a$

$k+1=-8\quad \quad \mathrm{or}\quad \:\quad \:k+1=8$

we get

$k+1=-8\quad$

$k=-9$

$k+1=8\quad$

$k=7$

so,

$k=-9\quad \mathrm{or}\quad \:k=7$ ...............Answer

Hello,

$f(x)=x^{-2}+4\\

f(-1)=(-1)^{-2}+4= \dfrac{1}{(-1)^2} +4=1+4=5\\

kicyunya [14]

Answer:

x= -4

Step-by-step explanation:

=> 1+2x= 4x+9

=> 1-9=4x-2x

=> -8 = 2x

=> x = -8/2

=> x= -4

hope it's helpful to you ☺️
