$6.70 + $1.95 + $2.35 = $11
4.5% sales tax is $0.50 so $11 + $0.50 = $11.50
$11.50 + $2.00 tip = $13.05

Answer:

$13.50

Step-by-step explanation:

So excluding tax and tip, let's find the cost of the meal.

$6.70 + $1.95 + $2.35 = $11.00

Now let's add the 4.5% tax. We do this by adding 4.5% of 11.00 to 11.00

$11.00 + 0.045($11.00) = $11.495 which rounds to 11.50

Now the tip is 2 dollars, so add 2 to 11.50 to get $13.50

Answer:

1) 26.1% increase

2) 20% decrease

Work:

-subtract the larger # from the smaller # to figure out what the change was.

$8.8 - 6.5 = 2.3$

-divide 2.3 by the orriginal ammount (8.8) to find your answer as a decimal

$2.3 \div 8.8 = 0.261$

-take 0.261 and multiply it by 100 to have your answer as a percent

$0.2614 \times 100 = 26.1$

-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease

-subtract the larger # from the smaller # to figure out what the change was.

$15 - 12 = 3$

-divide 2.3 by the orriginal ammount (15) to find your answer as a decimal

$3 \div 15 = 0.2$

-take 0.2 and multiply it by 100 to have your answer as a percent

$0.2 \times 100 = 20$

-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease

If the function m not-equals 0 has an inverse function, which statement must be true? B not-equals 0

Kipish [7]

Answer:

Option a: m ≠ 0

Step-by-step explanation:

After a small online search, I've found that the complete question is:

If the function f(x) = m*x + b has an inverse function, which statement must be true?

a) m ≠ 0

b) m = 0

c) b ≠ 0

d) b = 0

Ok, if g(x) is an inverse of the function f(x), then:

g( f(x)) = x

f( g(x)) = x

Let's assume that f(x) = m*x + b has an inverse, and this inverse function is g(x).

Because f(x) is linear, g(x) is also linear, then:

g(x) = n*x + c

Let's find the values of A and B.

We know that:

f( g(x)) = x = m*(n*x + c) + b

then

x = m*n*x + m*c + b

Then we must have:

m*n = 1

(m*c + b) = 0

From the first equation m*n = 1

We get:

n = 1/m

The slope of the inverse function is one over the slope of the original function.

Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)

Then the correct option is the option a, m ≠ 0.

Will mark brainlest if correct! pls help

Answer:

See below.

Step-by-step explanation:

$y_2 = 4x^2$

$x = 1$

$y_2 = 4(1)^2 = 4 = a$

a = 4

$y_3 = 4^x$

$x = 1$

$y_3 = 4^1 = 4 = b$

b = 4

$y_1 = 4x$

$x = 2$

$y_1 = 4(2) = 8 = c$

c = 8

$y_3 = 4^x$

$x = 2$

$y_3 = 4^2 = 16 = d$

d = 16

$y_1 = 4x$

$x = 3$

$y_1 = 4(3) = 12 = e$

e = 12

$y_2 = 4x^2$

$x = 3$

$y_2 = 4(3)^2 = 36 = f$

f = 36

$y_3 = 4^x$

$x = 3$

$y_3 = 4^3 = 64 = g$

g = 64
