Answer: y = (x + 1)*(x - 4)
Step-by-step explanation:
The points of the equation are:
( -2 ,6), ( -1 0)
, ( 0, -4) ( 1 ,-6) (2,-6) ( 4 ,0) and ( 5,6)
The first thing you can see is that the roots are:
( -1 0) and ( 4 ,0)
the roots are x1 = -1 and x2 = 4
and we know that we can write a polynomial as:
y = a*(x - x1)*(x - x2)
So our function can be:
y = a*(x - (-1))*(x - 4)
we also know that this graph passes trough the point (0, -4) so we can chek if this equation is correct:
y(0) = a*(0 + 1)*(0 - 4) = -4
a*1*-4 = -4
then y = (x + 1)*(x - 4)
Answer:
70
Step-by-step explanation:
7 and 10 = 70, This is the correct answer because 7 times 10 equals 70, and 10 times 7 equals 70 too, so 70 is the LCD
7 and 10 = 1, This is impossible because anything multiplied by 7 naturally does not get 1 as a answer, including 10 too. X
7 and 10 = 10, Only 10 times 1 equals 10, but 7 a natural whole number does not equal 10. X
7 and 10 = 35, Only 7 times 5 equals 35, but 10 times a whole number does not equal 35. X
In order to express 0.45 as a common fraction, all you have to do is first divide 45 to 100. So in order to get the answer to this, you just have to put 45 as the numerator and 100 as the denominator. This will become 45/100. To turn it into its simple form, you have to first ask yourself what is a common divisible number for the two. 5 can be divided by 45 and 100 so 5 can be used. So the final answer, if you make it into simplest form, will be 9/20
Answer:
blue
Step-by-step explanation:
it is going along with the points. we know it cant be red because that line is negative and the dots are going in a positive direction. we know it cant be pink bc it's not even going in the same direction as the points. so it has to be blue
