Answer:
f(x) = x² + 2x - 3
Step-by-step explanation:
From the graph the zeros are x = - 3 and x = 1
Thus the factors are (x + 3) and (x - 1) and
f(x) = (x + 3)(x - 1) ← distribute using FOIL
= x² - x + 3x - 3
= x² + 2x - 3
Answer:
7/8 - 4/8 = 3/8
6/8 - 2/8 = 4/8
3/8 < 4/8
Step-by-step explanation:
When you double the upper and lower part of a division at the same time, result doesn't change.
So you find the common ground for the equation to solve it.
Answer:
true
Step-by-step explanation:
Answer:
x= 11
y=14
z=17
Step-by-step explanation:
(Last number - first number in series) / numbers from the first to last number in series
(20-8)/4 = 3
8 + 3 = x
x + 3 = y
y + 3 = z
z + 3 = 20
Answer:
If the sign before the no. is same then they will get added and the resultant will have the same sign too.
Since before 28 and 12 , both of them have the negative sign , they will get added and the sign of their resultant will be negative too.
So , -28-12 = -40
Now, if the sign before the no.s are different then there will be subtraction, and the sign before the highest no. will be the sign of the resultant.
So,( -28)+38+(-12)
= -28+38-12
= -40+38
= -2
We know that 40> 38
sign before 40 is negative, therefore, their resultant i.e 2 will also get the negative sign
I hope this helps you...
