Answer:
The answer to your question is: Yes, x - 5 is a factor of the polynomial.
Step-by-step explanation:
To answer this question you need to divide the polynomial by the factor and if there is nothing left, they are factor.
<u>x³ -4x² -7x +10</u>
x -5
x² + x -2
x-5 x³ -4x² -7x +10
-x³ + 5x²
x² - 7x
-x² + 5x
-2x + 10
+2x -10
0 0 These zeros tell us that the linear
expression is a factor of the polynomial
The answer is 240.5 hope you get the question
Answer:
71
Step-by-step explanation:
vertical sides are congruent
x+30=101
x=71
Answer: ? = x + 1
Step-by-step explanation:
The perimeter of the garden is x + 3x + 1 + x + ?
The perimeter of the garden is also (6x + 2)
Therfore:
x + 3x + 1 + x + ? = 6x + 2
<em>Collect like terms: </em>
5x + 1 + ? = 6x + 2
<em>Subtract 5x from both sides:</em>
1 + ? = x + 2
<em>Subtract 1 from both sides:</em>
? = x + 1
You cannot find ? as a number, only in terms of x.
Answer:
y=2/7x+19/7
Step-by-step explanation:
Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7
Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:
y=2/7x+b
3=2/7(1)+b
3=2/7+b
21/7=2/7+b
19/7=b
Therefore, our final equation is y=2/7x+19/7
