Answer:
-3, 1
Step-by-step explanation:
f(x) = 3(x − 1)(x + 3)
To find the x intercepts, set the equation equal to zero
0 = 3(x − 1)(x + 3)
Using the zero product property
x-1 = 0 x+3 =0
x=1 x=-3
We gots a right triangle withe legs 8 and 15
remember if we got a right triangle with legs length a and b and hytponuse c then
a²+b²=c²
so
diagonal=c
so
8²+15²=c²
64+225=c²
289=c²
sqrt both sides
17=c
the diagonal is 17in
Answer:
n>=1
Step-by-step explanation:
30-5n<=25
5n<=30-25
5n<=5
n<=5/5
n<=1
n>=1
Answer:
65/100
Step-by-step explanation:
Since it is a whole percentage it would be over 100. Since its 65%, it would be 65/100
Answer:
a) D b)B
Step-by-step explanation:
a) the graph is of negative slope as it slants downwards hence slop/gradient is negative. y intercept is positive so only option d is right
b) sub each option point into 3y = 2x - 1 if they equate to be the same, it is correct.
3(2) = 2(6) - 1
6 = 11 (not equal)
3(1) = 2(2) - 1
3 = 3 (equal) this is the answer
of course you can sub in the rest to confirm but I'm lazy so yeah I'll stop here
