The midpoint formula states that the midpoint is equal to (x1 + x2/2, y1 + y2/2). However, in this instance, we only have to deal with the x-values because that is where our unknown variable x is. Using our formula for the x-values, we can set up the following equation:
(x + 9)/2 = 7
To solve this equation, we must first multiply both sides by 2 to get rid of the denominator on the left side of the equation.
x + 9 = 14
Next, we should subtract 9 from both sides of the equation to get the variable x alone on the left side.
x = 5
Therefore, your answer is x=5.
Hope this helps!
Answer:
To factor trinomals in the form of x^2+bx+c, you have to find 2 integers, r and s, whose product is c, and whose sum is b. You have to rewrite the trinomial as x^2+rx+sx+c and then using the grouping and distribution of property to factor the polynomial. The result of the factors will be (x+r) and (x+s)
Step-by-step explanation:
The polynomial will be given as P(x) = a(x + 3)² (x – 2)³. Then the correct option is D.
A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.
5th degree polynomial has a zero at x= -3 with multiplicity of 2 and a zero of x=2 with multiplicity of 3 and value of the function is neg. when x = -4.
Then the factor of the polynomial will be (x + 3) and (x – 2).
Then the polynomial will be given as,
P(x) = a(x + 3)² (x – 2)³
Where a is the leading coefficient.
Then the correct option is D.
