Which of the following explains why f(x) = log4^x

AVprozaik [17]

Answer:

There is no power of 4 that is equal to 0.

Step-by-step explanation:

$f(x) = log \: {4}^{x} \\ \\ plug \: x = 0 \\ \\ f(0) = log \: {4}^{0} \\ \\ f(0) = log \: 1 \: ( \because \: {n}^{0} = 1) \\ \\ f(0) = 0 \: ( \because \: log \: 1 = 0)$

Hence, f(x) = log4^x

does not have a y-intercept.

At Taco Bell, I made a large purchase of 13 items that cost a total of $28.17. If Chicken Burritos cost $1.89 each and a Cheesy

Sonja [21]

Answer:

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6

Step-by-step explanation:

Let x be the number of Chicken Burritos and y be the number of Cheesy Gordita Crunch.

Total number items purchased=13

Total cost of 13 items=$28.17

Cost of each Chicken Burritos=$1.89

Cost of each Cheesy Gordita Crunch=$2.49

We have to find number of each items purchased.

According to question

$x+y=13$ .....(1)

$1.89x+2.49y=28.17$ ...(2)

Equation (1) multiply by 2.49 and then subtract equation (2) from (1)

$0.6x=4.2$

$x=\frac{4.2}{0.6}$

x=7

Substitute x=7 in equation (1)

$7+y=13$

$y=13-7=6$

Number of Chicken Burritos purchased=7

Number of Cheesy Gordita Crunch purchased=6

The difference of two rational numbers is always negative true of false

Vlada [557]

Comparing two rational numbers

Use fraction form:

Make the denominators the same and compare the numerators. The number with the smaller numerator is smaller. For example, to compare a/b and c/d, we rewrite

a/b=a*d/b*d

= ad/bd and c/d = c*b/d*b=bc/bd

Now just compare the numerators : "ad" and "bc"

Multiplying and Dividing Rational Numbers

Multiplying and dividing rational numbers in decimal form is the same as multiplying and dividing integers. The decimal place of the product is the same of all decimals of all multiplied numbers. For example, 3.12*2.4.

Solution => 3.12*2.4=7.488

When multiplying or dividing rational numbers in fractional form, you multiply the numerators (N*N) and then multiply the denominators (D*D).

When dividing rational numbers in fractional form, first take the reciprocal of the divisor, and then multiply the numerators and the denominators.

Example => 5/9 divided by 2/7 .

Solution => 5/9 * 7/2 = 35/18

Adding Rational numbers

Adding and Subtracting rational numbers in decimal form is the same as adding and subtracting integers.

Example => -3.54+2.79=-0.75

When adding or subtracting rational numbers in fractional form, first make the denominator equal, and then add or subtract the numerators.

The difference can be negative or positive.
