Answer:

x = 1 and x = 9

Step-by-step explanation:

the known solutions are simply the values of x which causes the SAME number to show up in f(x) and g(x).

if we go down the table, we see that for x = 1, the same number 14 shows up for both f(x) and g(x), hence x=1 is a solution.

the same occurs for x = 9 giving 6 as the same solution for f(x) and g(x)

no other values of x causes this to occur.

hence the 2 known solutions are x = 1 and x = 9

Four more than three times a number is greater than twenty-two

Delvig [45]

Answer:

3x + 4 > 22 // x = 7 or up

Step-by-step explanation:

I assume this is a 'Take words and put into an equation' so here

'Three times a number'

Lets say a number is represented by x, it'd be 3x

'Four more than'

That's addition, adding onto the previous number it would be 3x + 4

Finally the 'Greater than 22' is > this sign

3x + 4 > 22

If you need to solve for x, then whatever is multiplied by 3 then added by 4 must be more than 22. It can really be anything 7 and up. 3x5 is 15, add 4 and it's 19, which is less than 22. 3x6 is 18, add 4 and its 22, that's equal to it, not greater than. 3x7 is 21, add 4 and it's 25. Anything further along with that will be greater than 22.

Which comparison is correct?

r-ruslan [8.4K]

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is the correct answer.

Explanation:

Option A: $7.1 \times 10^{8}>1.2 \times 10^{9}$

Simplifying, we get,

$710000000>1200000000$

Since, the value of $1.2 \times 10^{9}$ is greater than $7.1 \times 10^{8}$ , the comparison $7.1 \times 10^{8}>1.2 \times 10^{9}$ is false.

Hence, Option A is not the correct answer.

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$

Simplifying, we get,

$0.0000045>0.0000000039$

Since, the value of $4.5 \times 10^{-6}$ is greater than $3.9 \times 10^{-9}$ , the comparison $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is true.

Hence, Option B is the correct answer.

Option C: $$2.4 \times 10^{-5}$

Simplifying, we get,

$0.000024$

Since, the value of $2.4 \times 10^{-5}$ is greater than $5.7 \times 10^{-6}$ , the comparison $$2.4 \times 10^{-5}$ is false.

Hence, Option C is not the correct answer.

Option D: $$8.2 \times 10^{-4}$

Simplifying, we get,

$0.00082$

Since, the value of $8.2 \times 10^{-4}$ is greater than $3.6 \times 10^{-6}$ , the comparison $$8.2 \times 10^{-4}$ is false.

Hence, Option D is not the correct answer.

Please Help ! Its a math problem !!! Given the tables below, what is the difference between the average rates of change over the

nydimaria [60]

Answer:

Step-by-step explanation:

Average rate of change (Table 1) :

A(x) = h(4) - h(1) / 4 - 1
A(x) = 9 - 3 / 4 - 1
A(x) = 6/3 = 2

Average rate of change (Table 2) :

A(x) = j(4) - j(1) / 4 - 1
A(x) = 0 - 6 / 4 - 1
A(x) = -6/3 = -2

Difference : -2 - 2 = <u>-4</u>

Mr. and Mrs. Parker's bed is 2 1/3 yards wide. That also have 2 nightstands that are 22 inches wide. The bedroom wall is 12 1/2

vampirchik [111]

Conversions: to smallest (inches)
n= 22 inches
b= 2 1/3 yard = 84 inches
t= 12 1/2 feet = 150 inches

total space = t
night stand = n (2n for two nightstands)
bed=b

b+2n has to be < or = to t

84+2(22)=x
84+44=128
128 is < 150

therefore the answer is yes they will fit with 22 inches left over.
