One solution because it only has one answer that can come out if those properties. If you add the -3 to -6 it will make it 6=12 -3x. Subtract the 12 it will be -6=-3x divide by -3 and x=2

f(3) = 1.9

Solution:

Given function:

$$f(x)=\frac{14}{7+2 e^{-0.6 x}}$

To find f(3):

Substitute x = 3 in the given function.

$$f(3)=\frac{14}{7+2 e^{-0.6 (3)}}$

$$f(3)=\frac{14}{7+2 e^{-1.8}}$

Let us first simplify $2e^{-1.8}$ .

Apply exponent rule: $a^{-b}=\frac{1}{a^{b}}$

$2e^{-1.8}=2\frac{1}{e^{1.8}}$

The value of $e^{1.8}=6.04964$ . (using calculator)

$$\frac{2}{e^{1.8}}=\frac{2}{6.04964}=0.33059$

$2e^{-1.8}=0.33059$

Substitute this value in f(3).

$$f(3)=\frac{14}{7+0.33059}$

$$f(3)=\frac{14}{7.33059}$

$$f(3)=1.90980$

f(3) = 1.9

Hence the value of f(3) is 1.9.

Y = 3x – 5<br> y= 1/2x + 5<br> Solve

Varvara68 [4.7K]

Answer:

(4, 7 )

Step-by-step explanation:

y = 3x - 5 → (1)

y = $\frac{1}{2}$ x + 5 ( multiply through by 2 to clear the fraction )

2y = x + 10 → (2)

Substitute y = 3x - 5 into (2)

2(3x - 5) = x + 10 ← distribute parenthesis on left side

6x - 10 = x + 10 ( subtract x from both sides )

5x - 10 = 10 ( add 10 to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

Substitute x = 4 into (1) and evaluate for y

y = 3(4) - 5 = 12 - 5 = 7

solution is (4, 7 )
