2014年5月31日 · 3x means you have three x's. Then 3x - x means you have three x's and you take away (subtract) one x. This would leave you with two x's.

Mohammad N. asked • 12/06/20 Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y = 3x^5, y = 3x, x ≥ 0; about the x-axis

2025年1月7日 · If you were given this same function which is g(x)=x^2-4 and asked what is g(2), you would of simply plugged in the value 2 in the given function. This would yield: g(2)=2^2-4=0. Think of it in the same exact manner but instead of plugging in the value "2", plug in "3x" in the given equation. This would yield: g(3x)=(3x)^2-4=9x^2-4.

2015年10月29日 · In this problem I think that f-1 (x) represents the inverse function, not a negative exponent. To find the inverse function you have to solve the original equation for x in terms of y. Remember that f(x) is just another term for y, so the original equation is

2020年5月19日 · Hello Mylah, To solve this problem, start by fully expanding the original expression: 2(x 2 –1) + 3x(x–4). 2x 2 –2 + 3x 2 –12x

2023年2月10日 · Write Cos (3x) = 4cos 3 (x) - 3cos(x) Now cos(3x) + cos(x) = 4cos 3 (x) - 2cos(x) = 0. You can write Cos(x) = 0, 2cos 2 (x) - 1 = 0 implies cos(2x) = 0. Therefore, x = 90 o + 180 o k, 45 o + 90 o k where k is any integer (Z). The same could also be expressed in pi radians by substituting pi/4 = 45 o, pi/2 =90 o and pi = 180 o. Hope this helps.

symbol. A * symbol is not necessiary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x – 1). Order of Operations

The following are like terms because each term consists of a single variable, x, and a numeric coefficient. 2x, 45x, x, 0x, -26x, -x. Each of the following are like terms because they are all constants. 15, -2, 27, 9043, 0.6. Each of the following are like terms because they are all y 2 with a coefficient. 3y 2, y 2, -y 2, 26y 2

2020年12月11日 · First multiply the two first terms in each section: 3x*x = 3x 2. Next, multiply the two Outer terms together: 3x*2 = 6x. Third, multiply the two Inner terms together: 4*x = 4x. Finally, multiply the two Last terms: 4/*2 = 8. Sum all these terms and combine, where possible: 3x 2 + 6x + 4x + 8 = 3x 2 + 10x + 8. The answer is 3x 2 + 10x + 8. I ...
