6x-3y=20 through (4,-3)

1 answer:

7 0

Well x = 4 and y = -3 so what we would do is plug in the numbers like this.
6 x 4-3 x -3 = 20
Then lets break down the problem.
6x4=24 and 3x-3=-9
Now plug those numbers into our equation.
24 - (-9)=20
Then figure out the problem.
24 - (-9) = 33
So the x,y is wrong.

Solve for x. Please help quick, it’s my last question for my test

Answer:

x = 9

Step-by-step explanation:

84 + (7x + 5) + (180 - (17x-1)) = 180

84 + 7x + 5 + (181 - 17x) = 180

270 + (-10x) = 180

90 = 10x

x = 9

Find the value of x. x√5=x^4

Kaylis [27]

Answer:

x=0, $\sqrt[6]{5}$

Decimal form,

x=0,1.30766048......

Step-by-step explanation:

x $\sqrt{5}$ = $x^{4}$

x $\sqrt{5}$ - $x^{4}$ =0

(take x as a common factor)

x( $\sqrt{5}$ - $x^{3}$ )=0

So,

x=0 and $\sqrt{5}$ - $x^{3}$ =0

for $\sqrt{5$ - $x^{3}$ =0

(add $x^{3}$ for both sides)

$\sqrt{5}$ = $x^{3}$

x= $\sqrt[3]{\sqrt[2]{5} }$ (multiply 3 by 2)

x= $\sqrt[6]{5}$

So,

x=0, $\sqrt[6]{5}$

Calculate dy/dx if Ln (x + y) = e^x/y<br> Pic included

vesna_86 [32]

The first thing you should do when dealing with implicit derivatives is to respect the rules of derivation of both the logarithm and the exponential
Then, you must regroup the terms correctly until you get dy / dx
The answer for this case is D
I attach the solution
