Show that the equation x^3 + x -3 =0 has a solution between 1 and 2. That is the only information given

valentina_108 [34]

Answer:

Step-by-step explanation:

Given that:

$f(x) = x^3 + x - 3 = 0$

Since the given function is equal to zero, then the function :

$f(x) = x^3 + x - 3$

where;

$x = 1$ and

$x = 2$

$f(x) = (1)^3 + (1) - 3 \\ \\ f(x) = 1 + 1 - 3 \\ \\f(x) = -1 < 0$

$f(2) = x^3 + x - 3 \\ \\f(2) = (2)^3 + 3 - 3 \\ \\f(2) = 8 + 3 - 3 \\ \\f(2) = 11 - 3 \\ \\f(2) = 8 > 0 \\ \\$

Thus; f(1) < 0 and f(2) > 0

If u subtract 17 from my number and multiply the difference by -7, the result is -35.What is my number

Kryger [21]

Let x = your number.

(x - 17) * -7 = -35. Divide each side by -7.

(x - 17) = 5. Add 17 to each side.

x = 22.

Your number is 22

Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 × $\frac{100-10}{100}$ × $\frac{100+6}{100}$

Hence, the price of video after discount coupon and sales tax= $ 49 × $\frac{90}{100}$ × $\frac{106}{100}$

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax= $46.746

Hence, the correct answer is $46.746
