Keith plans to buy a car in the future.He currently has $3000 saved up to buy a car. How much money does he need to save per mon
Brut [27]

Answer:

about $709 per month

Step-by-step explanation:

Okay, so in order to solve this question, we should follow this formula:

3,000 + 24x \geq 20,000

where 24 is the amount of time we have and x is the variable we are using as to show the unknown amount of money earned per month.

3,000 + 24x \geq 20,000

-3,000               -3,000

24x \geq 17,000

/24           /24

x \geq approximately 709 dollars

so, we substitute x for 709

3,000 + 24(709) \geq 20,000

3,000 + 17,016 \geq 20,000

20,016 \geq 20,000

which is true

Hope this helps :)

The function f is defined as follows for the domain given.
SCORPION-xisa [38]

Answer:

The range of the function in ascending order is:

Range R = {-2, 0, 2, 4}

Step-by-step explanation:

Given the function

f(x) = 2-2x

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,  

  • Domain refers to all the possible sets of input values on the x-axis

As the domain of the function is given such as

Domain D = {-1, 0, 1, 2}

<u>Determining the range </u>

We also know that range is the set of values of the dependent variable for which a function is defined.  

In other words,  

Range refers to all the possible sets of output values on the y-axis.

As the domain is

Domain D = {-1, 0, 1, 2}

FOR x = 1

substitute x = -1 in the function

f(x) = 2-2x

f(-1) = 2-2(-1) = 2+2=4

so

at x = -1, y = 4

FOR x = 0

substitute x = 0 in the function

f(x) = 2-2x

f(-1) = 2-2(0) = 2-0=2

so

at x = 0, y = 2

FOR x = 1

substitute x = 1 in the function

f(x) = 2-2x

f(-1) = 2-2(1) = 2-2=0

so

at x = 1, y = 0

FOR x = 2

substitute x = 2 in the function

f(x) = 2-2x

f(-1) = 2-2(2) = 2-4=-2

so

at x = 2, y = -2

Thus combining all the output or y values correspond to the given input values, we get the range of the function.

Thus, the range of the function in ascending order is:

Range R = {-2, 0, 2, 4}

How to find the missing angle of a triangle using trig when you only know 1?
Sedbober [7]
If you have

2 KNOWN sides & 1 Angle ;
Use Cosine Rule

If you have 3 KNOWN sides,
Also Cosine Rule

If you have

2 KNOWN angles & 1 side,
Use SINE rule

If it's a right-angled triangle, use SOH CAH TOA

Hopefully this helps
