Okay so my teacher gave me this question "5=-3+y" can someone help me under stand it??

umka2103 [35]

Answer:

5=-3+y

inverse property. -3 + 3 = 0 so we add 3 to both sides to cancel out the -3 to ISOLATE the y.

5 = -3 + y

-3 + 3

-3 + 3 = 0

5+3 = 8

8 = y.

y = 8 basically. I hope that helped.

A farmer sells 7.7 kilograms of apples and pears.3/5 of this weight is apples, and the rest is pears. How many kilograms of pear

kompoz [17]

Answer:

The weight of pears is 3.08 kg

Step-by-step explanation:

A farmer sells 7.7 kilograms of apples and pears.

3/5 of this weight is apples.

This means that the weight of apples is:

3/5 of 7.7

=> $\frac{3}{5} * 7.7 = 4.62kg$

The weight of apples is 4.62 kg.

The weight of pears will therefore be:

$7.7 - 4.62 = 3.08 kg$

The weight of pears is 3.08 kg.

If f(x) and it’s inverse function, f^-1(x), are, both plotted on the same coordinate plane, what is their point of intersection

Korolek [52]

Answer:

Step-by-step explanation:

Hello,

there is not always an intersection point

let's take the example of on the appropriate domain

$f(x)=e^x \ \ \ f^{-1}(x)=ln(x)$

there is no intersection point

if there is one it means that the point (x,f(x)) and the point (x, $f^{-1}(x)$ ) is the same so that have to solve

$f(x)=f^{-1}(x)$

for instance if we take

$f(x)=x^2 \ \ \ f^{-1}(x)=\sqrt{x} \ \ \ for \ x >= 0$

intersection point are for x >= 0

$x^2=\sqrt{x} x^4=xx^3=1 \ or \ x=0 x = 1 \ or \ x=0$

hope this helps
