Answer:

x=5.4; y=8/5

Step-by-step explanation:

2x-3y=6

3x-2y=5

--------------------------

6x-9y=18

6x-4y=10

-----------------------------

5y=8

y=8/5

--------------------------

2x-3(8/5)=6

2x-4.8=6

2x=10.8

x=5.4

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.
Citrus2011 [14]

Answer:

f'(x)=-5ae^{ax}=a f(x), where a be a constant.

Step-by-step explanation:

Note: The given functions is a constant function because variable term is missing.

Consider the given function is

f(x)=-5e^{ax}

where a be a constant.

We need to find the derivative of the function.

Differentiate with respect to x.

f'(x)=\dfrac{d}{dx}(-5e^{ax})

f'(x)=-5\dfrac{d}{dx}(e^{ax})

f'(x)=-5e^{ax}\dfrac{d}{dx}(ax)            [\because \dfrac{d}{dx}(e^x)=e^x]

f'(x)=-5ae^{ax}

f'(x)=a(-5e^{ax})

f'(x)=a f(x)

Therefore, the derivative of the function is f'(x)=-5ae^{ax}=a f(x).

aleksley [76]

Answer:

6 $1 bills, 5 $5 bills

Step-by-step explanation:

Say the student has x $1 bills.

Then they have 11 - x $5 bills.

31 = 1 * x + (11 - x) * 5 = 55 - 4x

4x = 55 - 31 = 24

x = 6

So, they have 6 $1 bills and 11 - 6 = 5 $5 bills

Find the missing angle
Natasha_Volkova [10]

Answer:

56deg

Step-by-step explanation:

A triangle has 180deg.

180 = 68 + 56 + x       >> add 68 and 56

180 = 124 + x              >> subtract 124 from both sides

56 = x

The missing side is 56deg
