What is the domain of 3x²-4x 7?
Since it is a polynomial we know right away the domain is all real numbers.
5x - 4x plus 3 equals 7?
5x-4x+3=7just adding steps5x-4x+3=7you put numbers to getter but change sign5x-4x=7-35x-4x=4then it is clear5(4)-4(4)=720-16=7so as he said x=4
What is the product of 4 and a number increased by 7 is -36?
To answer this, first convert it into an equation: (4)(x+7) = -36 Now, solve for x: (4)(x+7) = -36 4x+28 = -36 4x = )-36)-28 4x = (-36) + (-28) 4x = -64 x = (-64)/4 x = -16
If the product of some number and 4 increased by 7 equals 3 then what is the number?
-1 Here is why: let x be the number, 4x+7=3 4x=3-7=-4 so 4x=-1 and x is -1
What expression has three terms and simplifies to 4x -7?
4x - 3 - 4 is one possible answer.
What are the factors of the polynomial x2 plus 4x - 21?
(x+7) and (x-3)
What are the factors of this polynomial 12j to the 3rd plus 28?
4(3j3 + 7)
In the expression 4x + 7, what is the constant term?
4x + 7 = 0 4x = -7 4x/4= -7/4 X = -7/4
Is 4-3x a polynomial?
7
What is the solution for x if sqrt parentheses 4x plus 7 endparentheses minus 4 equals sqrt parentheses 4x minus 1 endparentheses?
sqrt(4x+7) -4 = sqrt(4x-1) squared : (sqrt(4x+7) -4)2 = 4x-1 (4x+7) - 2x4xsqrt(4x+7) +16 = 4x-1 -8xsqrt(4x+7) = -24 sqrt(4x+7) = -24/-8 = 3 squared : 4x+7 = 32 = 9 4x = 9-7 = 2 then x=1/2
What is the quotient of the polynomial 4x exponent four minus x cubed plus 17x squared plus 11x plus 4 when divided by the expression 4x plus 3?
x3-x2+5x-1 with remainder 7, which the final answer would be written as:x3-x2+5x-1+[7/(4x+3)]
What is the domain of 3x²-4x 7?
Since it is a polynomial we know right away the domain is all real numbers.
How do you solve 4x - 4y plus 7 equals 15?
4x - 4y + 7 = 15to get it into y-intercept form do this...4x -4x - 4y + 7 - 7 = 15 - 7 - 4x-4y = 8 - 4x-4y / -4 = (8 / -4) + (-4x / -4)y = x + 2you did not give any values to plug in so this is as best an answer i can give
Write 8x2 plus 6x - 35 as a polynomial in descending order?
Type your answer here... (2x + 5)(4x - 7)
Is it possible to have a cubic binomial in algebra?
Yes, it is when a polynomial has two terms with a degree of 3. ex: 4x^3+7
What are the factors of x2 plus 4x-21?
x2 + 4x - 21 = (x + 7)(x - 3). The trick is to find 2 numbers which sum to 4 and have a product of -21.
What value of x will make the polynomial 0 if its factors are x-3 and x-4?
x-2 and x -7?
