rodikova [14]

Answer:

Roasted Steak RS=14.47

Grilled Salmon GS= 25.21

Step-by-step explanation:

It's a 2 equation system as follows

E1-> 17RS+14GS=598.95

E2-> 28RS+7GS=581.64

We assume the system has only one solution and apply the following calculation to create a single equation

E3 -> 2x E2 -E1

That way the only incognit will be RS

(28x2 - 17) RS + (7x2 - 14) GS = 581,64x2- 598,95

39RS= 564,33

We solve for RS and then use E1 to solve for GS and E2 to check the answers

32<br> what value of x is the equation 2^2x+ 7 = 2^15true?
Talja [164]

Value of x = 7.499

Step-by-step explanation:

We need to find value of x in the equation: 2^{2x}+ 7 = 2^{15}

This can be solved using natural log

Solving:

2^{2x}+ 7 = 2^{15}

Subtract 7 from both sides:

2^{2x}+ 7-7 = 2^{15}-7

Simplifying:

2^{2x}=32768-7

2^{2x}=32761

Using rule if f(x)=g(x) then, ln(f(x))=ln(g(x))

So,

ln(2^{2x})=ln(32761)

Applying log rule: logₐ(x^b)= b logₐ(x)

2x(ln(2))=ln(32761)

Divide both sides by 2ln(2)

2x(ln(2))=[tex]\frac{2x(ln(2))}{2(ln(2))}=\frac{ln(32761)}{2(ln(2))} \\x=\frac{ln(32761)}{2(ln(2))}\\Rewriting\,\,32761\,\,as 181^2\\x=\frac{ln(181^2)}{2(ln(2))}\\x=\frac{2ln(181)}{2(ln(2))}\\x=\frac{ln(181)}{ln(2)}\\x=7.499

So, Value of x = 7.499
