1.) add 9 and 5 which is 14-6x
The graph is crossing the x-axis at x = 0 and x = 5
This means, x and x - 5 are the factors of the polynomial.
A polynomial can be expressed as the product of its factors. So the above polynomial can be expressed as x(x-5)
Thus, the correct answer to this question is option A
D.) 14
Because it’s going up four every time
Answer:
22,-89
Step-by-step explanation:
let the numbers be x and y .
x+y=-45
x-y=-89
add
2x=--134
x=-67
-67+y=-45
y=-45+67=22
Answer:
The third side is sqrt(77)
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
2^2 + b^2 = 9^2
4+ b^2 = 81
Subtract 4 from each side
b^2 = 81-4
b^2=77
Take the square root of each side
sqrt(b^2) = sqrt(77)
b = sqrt(77)
The third side is sqrt(77)
