The numbers represented by variables w and y on the number line are integers.

mixas84 [53]

Option A) when y=6 and w= 2, Option B) when y=4 and w=-1 are the TWO correct choices.

Step-by-step explanation:

The given inequality is w<x<y and x>2.

step 1: let us assume that x=3, since it is given that x>2.

step 2: substitute the value of x=3 and each options in the inequality

step 3: option A) w=2, y=6. Then w<x<y = 2<3<6 (the condition satisfies).

option B) w= -1, y=4. Then w<x<y = -1<3<4 (the condition satisfies).

option C) w= 0, y=2. then w<x<y ≠ 0<2<2 (does not satisfies).

option D) w= -2, y=0. then w<x<y ≠ -2<2<0 (does not satisfies).

option E) w= -4, y= -1. then w<x<y ≠ -4<2<-1 (does not satisfies).

Find the zeros of the following

13 ) Go...

$f(x) = {x}^{2} - 2x$

$0 = {x}^{2} - 2x$

${x}^{2} - 2x = 0$

Factor x

$x(x - 2) = 0$

$x = 0 \: \: \: or \: \: \: x - 2 = 0$

$x = 0 \: \: \: \: or \: \: \: \: x = 2$

These are the zeroes.

14 ) Go...

$f(x) = {x}^{3} + 9x + 11x - 21$

$0 = {x}^{3} + 9 {x}^{2} + 11x - 21$

${x}^{3} + 9 {x}^{2} + 11x - 21 = 0$

$(x - 1)(x + 3)(x + 7) = 0$

$x - 1 = 0 \: \: or \: \: x + 3 = 0 \: \: or \: \: x + 7 = 0 \\$

$x = 1 \: \: \: or \: \: \: x = - 3 \: \: \: or \: \: \: x = - 7 \\$

These are the zeroes.

Please help me out!!!!! :)

Answer:

x=7

Step-by-step explanation:

The two angles are alternate interior angles. If they lines are parallel, then the angles are equal.

7x-7 = 4x+14

Subtract 4x from each side

7x-4x -7 = 4x-4x+14

3x-7 = 14

Add 7 to each side

3x-7+7 = 14+7

3x=21

Divide by 3

3x/3 =21/3

x=7

2 Mini Lesson: A wireless phone plan costs Eric $35 for a month of service during which he sent 450 text messages. If he was cha

Explanation:

From your knowledge of the world, you know that ...

the cost of multiple items is the sum of their individual costs
multiplication can be used for repeated addition
utility fees are the sum of fixed fees and usage-related fees
for a phone plan, text message costs are a usage-related fee

The problem statement asks for the cost of a single text message. For the purpose of finding that value, it is convenient to represent it using the variable t. The problem statement says Eric was billed for 450 text messages, so we expect his usage-related fee to be 450t, the sum of the costs of 450 messages--using multiplication for the repeated sum.

The problem statement says Eric was billed 12.50 for fixed fees. So, we expect Eric's total bill to be ...

fixed fees + usage-related fees = 12.50 + 450t

The problem statement says Eric's total bill was 35.00, so we assume that is the sum of the above-listed fees. That is, the two ways to express Eric's total bill are equal.

12.50 +450t = 35.00
