What is the domain and range of f(x) = 3(4)^x

Mathematics

Answer:

Step-by-step explanation:

Find the y-intercept by setting x = 0: f(0) = 3(4)^0 = 3(1) = 3 => (0, 3)

4^x is never zero, and its graph is always above the y-axis, for both positive and negative x.

Any real number is an acceptable x-value.

Thus the domain is (- infinity, infinity) and the range is (0, infinity).

2(6x + 1) - 4(x - 5) = -2

mr_godi [17]

Answer:

x=−3

Step-by-step explanation:

2(6x+1)−4(x−5)=−2

Step 1: Simplify both sides of the equation.

2(6x+1)−4(x−5)=−2

(2)(6x)+(2)(1)+(−4)(x)+(−4)(−5)=−2(Distribute)

12x+2+−4x+20=−2

(12x+−4x)+(2+20)=−2(Combine Like Terms)

8x+22=−2

Step 2: Subtract 22 from both sides.

8x+22−22=−2−22

8x=−24

Step 3: Divide both sides by 8.

8x/8=−24/8

How many drahms areequivalent to 300 grains?

GenaCL600 [577]

hello

to solve this question, we need to know how many grains is in 1 gram

$\begin{gathered} 1\text{grams}=15.43\text{grains} \\ \end{gathered}$

now let 300 grains be equal to x grams

$\begin{gathered} 1\text{grams}=15.43\text{grain} \\ \text{xgrams}=300\text{grains} \\ \text{cross multiply both sides and solve for x} \\ x\times15.43=1\times300 \\ 15.43x=300 \\ \text{divide both sides by 19.44} \\ \frac{15.43x}{15.43}=\frac{300}{15.43} \\ x=\frac{300}{15.43} \\ x=19.44 \end{gathered}$

300 grains will weigh 19.44g
