Answer:

Step-by-step explanation:

x + 3 = -x - 5

2x + 3 = -5

2x = -8

x = -4

Answer: x=-4

Step-by-step explanation: first add x from both sides to turn it into 2x+3=-5. then subtract 3 from both sides for it to turn to 2x=-8. finally divide both sides by to to find x=-4

Answer:

Step 1 Remove the decimal and write the given number divided by 1

Step 2 After decimal how many digits are there write that much 0 after 1

Step 3 Then Simplify or reduce the fraction

Answer:

When I work with function composition, I usually convert "( f o g)(x)" to the more intuitive " f (g(x))" form. This is not required, but I certainly find it helpful. In this case, I get:

(g o f )(1) = g( f(1))

This means that, working from right to left (or from the inside out), I am plugging x = 1 into f(x), evaluating f(x), and then plugging the result into g(x). I can do the calculations bit by bit, like this: Since f(1) = 2(1) + 3 = 2 + 3 = 5, and since g(5) = –(5)2 + 5 = –25 + 5 = –20, then (g o f )(1) = g( f(1)) = g(5) = –20. Doing the calculations all together (which will be useful later on when we're doing things symbolically), it looks like this:

(g o f )(1) = g( f (1))

  = g(2(   ) + 3)   ... setting up to insert the original input

  = g(2(1) + 3)

  = g(2 + 3)

  = g(5)

  = –(   )2 + 5    ... setting up to insert the new input

  = –(5)2 + 5

  = –25 + 5

  = –20

Note how I wrote each function's rule clearly, leaving open parentheses for where the input (x or whatever) would go. This is a useful technique. Whichever method you use (bit-by-bit or all-in-one), the answer is:

(g o f )(1) = g( f (1)) = –20

I just computed (g o f )(1); the composition can also work in the other order

Step-by-step explanation:

The value of a is 4.

Hence, a = 4

Here,

[tex]f(x) = (5 - x)^3 and, g(x) = a + x^2,[/tex]

and [tex]f(g(x)) = (1 - x^{2} )^3[/tex]

We have to find the value of a.

What is composite function?

Function composition is an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x)).

Now,

[tex]f(x) = (5 - x)^3 and, g(x) = a + x^2,[/tex]

and [tex]f(g(x)) = (1 - x^{2} )^3[/tex]

⇒ [tex]f(g(x)) = f ( a + x^{2} )[/tex]

⇒ [tex]f ( a + x^{2} ) = ( 5 - a - x^{2} )^3[/tex]

And,

[tex]f(g(x)) = (1 - x^{2} )^3[/tex]

[tex]( 5 - a - x^{2} )^3 = ( 1 - x^{2} )^3\\[/tex]

Taking cube root both sides,

[tex]( 5 - a - x^{2} ) = ( 1 - x^{2} )\\ 5 - a - x^{2} = 1 - x^{2} \\a = 4[/tex]

Hence, The value of a = 4.

C. Financing a brand new Car

Step-by-step explanation:

Financing a brand new car means that someone takes out a car loan that has to be paid over time, and that is something a spender would do because they are not saving money

Answer:

C

Step-by-step explanation:

It is a function because it passes the vertical line test and Xs do not repeat, then count out the Y-values which are the range.

Step-by-step explanation:

Notice it is not asking for an average rate, just her current rate. Approach this like this: say she is at the 29 mile "marker." In 3 hours, she gets to the 38th mile "marker." Therefore:

38-29 = 9, so in 3 hours, she went 9 miles.

9 miles/3 hours = 3 miles per hour, which would be equal to her current rate.

Answer:

∠B = 52°.

Step-by-step explanation:

Given: m∠A=(8x-4)° and m∠B=(7x+3)°. ∠A and ∠B are vertical angles.

Since ∠A and ∠B are vertical angles. So, there measure are equal.

[tex]m\angle A=m\angle B[/tex]

[tex](8x-4)^{\circ}=(7x+3)^{\circ}[/tex]

[tex]8x-4=7x+3[/tex]

[tex]8x-7x=4+3[/tex]

[tex]x=7[/tex]

Now,

[tex]m\angle B=(7(7)+3)^{\circ}[/tex]

[tex]m\angle B=(49+3)^{\circ}[/tex]

[tex]m\angle B=52^{\circ}[/tex]

Therefore, the measure of ∠B is 52°.

Answer:

G. $9,200

Step-by-step explanation:

average depreciation = (amount of depreciation)/(number of years)

The amount of depreciation is the difference between the new cost and the current value.

amount of depreciation = $85,600 - $30,400 = $55,200

number of years = 6

average depreciation = (amount of depreciation)/(number of years)

average depreciation = ($55,200)/(6 years)

average depreciation = $9,200/year

So:

[tex]9x \cdot 3 = 27x[/tex]

Answer:

  examine the next digit and increase the number accordingly, before dropping the digits of no interest.

Step-by-step explanation:

You round any number by looking at the digit in the place to the right of the one you want to round to. If it is 5 or more, you add 1 to the number in the place you're rounding to, and drop (or zero) all digits to the right of that.

If you want to round this to tenths, you observe that the hundredths digit is 7, which is more than 4. So you add 1 tenth and drop the hundredths digit:

  99.87 ≈ 99.9 . . . . rounded to tenths

If you want to round this to units, you observe that the tenths digit is 8, which is more than 4. So you add 1 unit and drop the tenths and hundredths digits.

  99.86 ≈ 100 . . . . . rounded to nearest integer

Answer:

  b)  f(3) is defined, but is not equal to the limit

Step-by-step explanation:

The portion of the function defined by the rational expression is equivalent to x/(x+3), which has a value of 1/2 at x=3. This is the limit of f(x) from the left or right as x approaches 3. However, the function is not defined at that point as 1/2. Rather, it is defined to be f(3)=1.

So, the limits at f(3) exist and are 1/2, but the function is defined as a different value there.

The only applicable statement is the second one.

Answer:

x=14

Step-by-step explanation:

2 times x = 2x and 2 time 9 is 18 so the equation is 2x-18=10. then you add 18 to both sides and get 2x=28 then simplify to x=14

Answer:

x=14

Step-by-step explanation:

2(x-9)=10

Step one - Simplify both sides

(2)(x)+(2)(-9)=10 (distribute)

2x+-18=10

2x-18=10

Step two - Add 18 to both sides

2x-18+18=10+18

2x=28

Step three - Divide both sides by 2

2x÷2 = 28÷2

x= 14

Step-by-step explanation:

Ok, so we know evaluate means to solve or to work out the situation. In this case we got 1.4•0.32. So, what we'll have to do is to solve this mathmatical equation 7/5 (1.4) • 8/25 (0.32) this in fractional form what we did is turnrf the decimal form of each reprecient of the problem into fractions. How to turn decimals in fractions is to simplify. Once, you've done that evaluate 7/5 and 8/25. This should get you 56/125.
