Answer: C :Determine whether 9 – 4(–x)² is equivalent to –(9 – 4x²).

Step-by-step explanation:

A function f(x) is odd if f(-x)=-f(x).

We have thus to determine if 9-4*(-x)²= -(9-4*x²).

which is false since this function is even !!!

Answer is C

Answer:

y = a - k

Step-by-step explanation:

k = a - y

k + y = a - y + y

k + y = a

k + y - k = a - k

y = a - k

High school A:  3 vans + 12 buses = 504 students

High school B: 2 vans + 4 buses = 184 students

Multiply High school B by 1.5:

High school B: 3 vans + 6 buses = 276 students

Subtract High school B from High School A:

6 buses = 228 students

Divide students by buses:

Buses = 228 / 6 = 38 students per bus

Now solve for vans using high school A:

3 vans + 12(38 students per bus) = 504 students

Simplify:

3 vans + 456 students in buses = 504 students

Subtract students in buses from both sides:

3 vans = 48

Divide both sides by 3:

Vans = 16

Answer: vans = 16 students, buses = 38 students

Answer:

y= -3x+4

Step-by-step explanation:

x+12=3y

(x+12)/3 = y

slope =

[tex] \frac{1}{3} [/tex]

the new slope = -3

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b

4 = -3×(0) + b

b= 4

so y= -3x+4

Answer:

211.143 233.916 Inflation rate: fo. Application of the formula to the inputs: IR = ?? -$0.10. Sample problem: The CPI value in January 2009 was 211.143

Step-by-step explanation:

The 5-year inflation rate between January 2009 and January 2014 is 10.78%.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, For calculate the 5-year inflation rate between January 2009 and January 2014, we can use the following formula:

Inflation rate = (CPI at end of period - CPI at beginning of period) / CPI at beginning of period x 100%

Hence, Using the values given, we can plug them into the formula:

Inflation rate = (233.916 - 211.143) / 211.143 x 100% Inflation rate

                   = 10.78%

Therefore, the 5-year inflation rate between January 2009 and January 2014 is 10.78%.

Answer: D

Step-by-step explanation:

To see whuch equation has solution x=3. we can just plug x=3 into each equation to see which is correct. Let's actually solve each equation for practice.

A. Incorrect

5x+4=22                    [subtract both sides by 4]

5x=18                         [divide both sides by 5]

x=18/5

------------------------------------------------------------------------------------------------

B. Incorrect

6x+1=-19                    [subtract both sides by 1]

6x=-20                       [divide both sides by 6]

x=-20/6

------------------------------------------------------------------------------------------------

C. Incorrect

3x-2=34                    [add both sides by 2]

3x=36                        [divide both sides by 3]

x=12

------------------------------------------------------------------------------------------------

D. Correct

6x+6=24                    [subtract both sides by 6]

6x=18                         [divide both sides by 6]

x=3

Now, we know that D is correct.
