Which value for x makes the sentence true?

4vir4ik [10]

Answer:

x = 2

Step-by-step explanation:

8x = 4x + 8

Subtract 4x from each side

8x-4x = 4x-4x + 8

4x = 8

Divide each side by 4

4x/4 = 8/4

x = 2

<h3><u>Question</u> :-</h3>

Is (x-2) is a factor of x³-3x²-x +7 –

Yes
No ☑

<h3><u>Explanation</u> :-</h3>

We are given –

Polynomial function, P(x) = x³-3x²-x +7

In order to check if x - 2 is a factor of x³-3x²-x +7 or not, we must show that P(2) = 0.

Let's find value of x!

$\qquad$ $\twoheadrightarrow\bf P(x) = x³-3x²-x +7$

$\qquad$ $\twoheadrightarrow\bf Q(x) =x - 2$

$\qquad$ $\twoheadrightarrow\bf If \:Q(x) = 0$

$\qquad$ $\twoheadrightarrow\bf x - 2 = 0$

$\qquad$ $\twoheadrightarrow\bf x = 2$

Now Put x = 2 into the polynomial –

$\qquad$ $\purple{\twoheadrightarrow\bf P(2) = 2³-3(2)²-2+7}$

$\qquad$ $\twoheadrightarrow\sf P(2) = 8 - 3 \times 4 +5$

$\qquad$ $\twoheadrightarrow\sf P(2) = 8 -12 +5$

$\qquad$ $\twoheadrightarrow\sf P(2) = 13-12$

$\qquad$ $\purple{\twoheadrightarrow\bf P(2) =1 }$

Since the value of the polynomial function st x = 2 is not Zero (0). Henceforth, ( x - 2) is a factor of x³-3x²-x +7.

24. Janet and Jack are walking in a two-day event to raise money for charity.

Serga [27]

Answer:

40 miles walk

Step-by-step explanation:

Let the miles walked by both of them be x at which money collected by same

for Janet

Fixed donation asked = $7.50

money asked for walking 1 mile = $0.10

money made by Janet if he walks x miles = x*$0.10 = $0.10x

Total money collected by Janet = Fixed donation asked + money made by Janet if he walks x miles

Total money collected by Janet =7.50 + 0.10x

For Jack

Fixed donation asked = $5.50

money asked for walking 1 mile = $0.15

money made by Janet if he walks x miles = x*$0.15 = $0.15x

Total money collected by Jack = Fixed donation asked + money made by Jack if he walks x miles

Total money collected by Jack =5.50 + 0.15x

we have to find miles at which money collected by both of them be same

and we have decided that it it as x mile walk then

Total money collected by Janet = Total money collected by Jack

7.50 + 0.10x = 5.50 + 0.15x

=> 7.50 - 5.50 = 0.15x - 0.10x

=> 2 = 0.05x

=> x = 2/0.05 = 40

Thus, at 40 miles walk money collected by both of them will be same

Answer:

A. x >= 16/5 or x <= -3/4

Step-by-step explanation:

5x - 4 >= 12

5x > = 16

x >= 16/5

and

12x + 5 <= - 4

12x <= - 9

x <= -9/12

x <= - 3/4

Answer

x >= 16/5 or x <= -3/4
