Answer:

x = 2/3

Step-by-step explanation:

If f(x) = -3x + 4, f(x) = g(x), and g(x) = 2, by the Transitive Property, -3x + 4 = 2

From here we can solve for x.

-3x + 4 = 2
-3x + 4 - 4 = 2 - 4
-3x = -2
3x = 2
3x/3 = 2/3
x = 2/3

The inequality that can be used to determine "x", the maximum number of outfits that Layla can purchase while staying within her budget is [tex][680\geq (371.90+77.02x)][/tex].

As per the question statement, Layla has a budget of $680 to spend at a bicycle store for some new gear and biking outfits, and she buys a new bicycle for $319.28, 3 bicycle reflectors for $4.90 each and a pair of bike gloves for $37.94.

We are required to express the inequality that can be used to determine "x", the maximum number of outfits that Layla can purchase while staying within her budget if a new biking outfit costs $77.02

First, let us calculate the total spending Layla has already done before going for new biking outfits, which is $319.28 on bicycle, 3 bicycle reflectors for $4.90 each and a pair of bike gloves for $37.94, summed up as [tex][319.28+(4.90*3)+37.94]=(319.28+14.7+37.94)=371.92[/tex]

And supposing that she buys "x" new biking outfits, of $77.02 each, the total spending has to be equal to, or less than $680, i.e.,

[tex][680\geq (371.90+77.02x)][/tex]

Hence, the inequality that can be used to determine "x", the maximum number of outfits that Layla can purchase while staying within her budget is [tex][680\geq (371.90+77.02x)][/tex].

If the original temperature is 190 degrees Fahrenheit and the freezer is 0 degrees Fahrenheit the temperature of the hot chocolate be after 4 minutes is: 117.57.

Given:

k=0.12

Original or initial temperature=190 degrees Fahrenheit

Freezer temperature = 0 degrees Fahrenheit

Using Newton's Law of cooling to find the temperature of the hot chocolate

Temperature (t)= Temperature of surrounding environment T1 +(initial temperature of object T0-Temperature of surrounding environment T1)e-^kt

Hence,

T(t)=0+(190-0)e^-0.12t

T(t)=190e^-0.12t

Where t=4

T(t)=190e^-0.12(4)

T(t)=190e^-0.48

T(t)=117.5688

T(t)=117.57 (Approximately)

Step-by-step explanation:

a normal function expresses y (the functional result) in terms of x (and constants).

we need to transform this to express now x in terms of y (and constants).

at the end we only rename x into y and y into x to make it an actual function.

h(x) = y = (-5x + 6)/(3x + 4)

y(3x + 4) = (-5x + 6)

3xy + 4y = -5x + 6

4y - 6 = -5x - 3xy = x(-5 - 3y)

x = (4y - 6)/(-5 - 3y)

and after renaming we get therefore the function

y = h-1(x) = (4x - 6)/(-3x - 5)

Answer:

r = 26

Step-by-step explanation:

Let's solve the problem,

→ 0.5r + 5 = r - 8

there are  a total of 7983360 way of arrangements of the pies.

As we are provided we  three pieces of apple pie, five pieces of cherry pie, and four pieces of pumpkin pie, in total 12 pies

So total combination will be

12! = 1*2*3*4*5*6*7*8*9*10*11*12

   = 479001600

In the event that there was 1 pie, at that point it would be fair 1 in its line. If we had 2 pies A and B, at that point we have 2 combinations AB and BA. Adding a 3rd pie C would multiply those combinations by 3, ABC, ACB, BAC, BCA, CAB, and CBA. If each pie piece may be a unique work of craftsmanship at that point 12! is the proper amount of combinations. On the off chance that you need combinations that disregard setups where for illustration two cherry pie pieces are compatible, meaning you want uniqueness at that point you divide 12! by 5 at that point by 3 and after that by 4.

For the given kite DCBA, the value of AD as 22 units and CB as 30 units.

We know that the two longer sides and the two shorter sides of the kite are equal to each other.

So, we get that:

AD = CD

Substituting the values, we get that:

11 y - 22 = 7 y - 6

11 y - 7 y = 22 - 6

4 y = 16

y = 16 / 4

y = 4

AD = 11 y - 22 = 44 - 22 = 22 units

AB = BC

Substituting the values, we get that:

3 x + 12 = 5 x

5 x - 3 x = 12

2 x = 12

x = 12 / 2

The number of minutes it takes Darius to reach the shipwreck is 8.75 minutes

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

Initial position = -5 feet

Rate = -8 feet per minute

Final position = - 75 feet

The linear equation of this situation is

Final position (y) = Initial position + Rate * Time (x)

So, we have

-75 = -5 -8x

This gives

-8x = -70

Divide both sides by -8

x = 8.75

Hence. the number of minutes it takes Darius to reach the shipwreck is 8.75 minutes

a-b = c (c may have a positive, negative, or even zero value.)

Given that, Andrew, Caren, and Barbara's combined age is 68 years.

asked them how many years back in total they had, so we had to take away five years from three of them to get,

In order to calculate their ages five years ago, take 15 out of 68.

68-15=53

this reveals Andrew, Caren, and Barbara's combined ages. five years ago

According to the statement, a vinegar solution with a given concentration must be prepared by using two vinegar solutions with different concentrations. We can find the required addition of the 30 % vinegar solution by weighted averages, whose respective formula is:

(20 / 100) · (4 + x) = (30 / 100) · x + (15 / 100) · 4

0.2 · (4 + x) = 0.3 · x + 0.15 · 4
