Yesterday morning at 8 a.m. the temperature was -14˚F. At noon it was 10 degrees warmer. The temperature increase between noon a

OLEGan [10]

The temperature was -14°F at 8 a.m.

At noon is was 10 degrees warmer - the temperature increase was 10°F
-14°F + 10°F = -4°F

The tempertaure increase between noon and 4 p.m. was twice the previous increase in temperature, which was 10°F.
10°F x 2 = 20°F

We want to know the temperature at 4 p.m. so we just add it up to the previous result.
-4°F + 20°F = 16°F

16°F is the correct answer

Which ordered pair is a solution of the equation 2x − y = 9?

gladu [14]

The correct answer is: [C]: " (5, 1) ".

__________________

Explanation:

__________________

Choice: [C]: " x = 5 " ; " y = 1 " ;

Note: Given the equation: " 2x - y = 9 " .

→ Plug in " 5 " for "x" , and " 1 for " y " ;

to get: " [2 * 5] - [1] = 10 - 1 = " 9 " ; and: " 9 = 9 " .

So, Choice: [C]: " (5, 1) " — is the CORRECT ANSWER.

__________________

Let us consider the "other answer choices" ; as follows:

__________________

Choice: [A]: "x = - 4 " , "y = 1" ; Plug in these values for the given equation:

→ " 2x - y = 9 " ;

→ " (2 * -4) - (5) = - 8 - 5 = " - 13 " ; and: " - 13 ≠ 9 " .

→ So: Answer choice: [A]: is INCORRECT.

__________________

Choice [B]: "x = -2" , "y = 5" ; Plug in these values for the given equation:

"2x - y = 9 " ;

→ " (2 * -2) - (5) = -4 - 5 = -9 ; and: " -9 ≠ 9 " .

→ So: Answer choice: [B]: is INCORRECT.

__________________

Choice: [D]: "x = 6 " , "y = - 3" ; Plug in these values for the given equation:

"2x - y = 9 " ;

→ " (2 * 6) - ( -3) = 12 - (-3) = 12 + 3 = " 15 " ; and: " 15 ≠ 9 " .

→ So: Answer choice: [D]: is INCORRECT.

__________________

→ The correct answer is: [C]: " (5, 1) " .

Which expression can be used to find the difference of the polynomials?

nadya68 [22]

Answer:

D is correct. ( 4m - 5 ) + ( -6m + 7 - 2n )

Step-by-step explanation:

We are given a difference of two polynomial

(4m-5) - (6m-7+2n)

We need to choose correct choice which is equivalent to given expression.

Here we have minus sign between two parentheses.

First we distribute minus sign over (6m-7+2n) using distributive property.

Minus sign will distribute with each term inside (6m-7+2n).

When it will distribute it changes the sign of each term inside the parentheses.

$6m\rightarrow -6m$

$-7\rightarrow +7$

$+2n\rightarrow -2n$

After distribution we get

( 4m - 5 ) + ( -6m + 7 - 2n )

Thus, D is correct option which is similar to given expression.
