Answer:
THis does that give me enough information to answer.
Step-by-step explanation:
I'm pretty sure you are asking for the value of b. Let's actually write it and then solve it:
Solving for b yields:
So,
b = 19.59. If you want the answer in simplified radical form, we can also do that:
So,
b = 8√6 = 19.59
The answer in exponent form is 2x2x2x2x2x3=96
(5x - 3y =23) + (7x +3y = -11) =
12x = 12
x = 1
Substitute
5(1) -3y =23
5 - 3y = 23
-3y = 18
y = -6
x=1 and y=-6
Finding zeros or setting y ot f(n) equal to zero
and all you have to do is factor it, hoping you know how to do this
5. 0= n^2-2n-15
(n-5)(n+3)= 0
n-5= 0 n+3=0
n=5 and n=-3
6.t^2+6t=27
t^2+6t-27=0
(t + 9) (t-3)= 0
t=-9 and t=3
7. x^2-9x=-18
x^2-9x+18=0
(x-6)(x-3)= 0
x=6 and x=3
8. a^2 - 7a = 30
a^2 - 7a -30= 0
(a-10)(a+3)=0
a=10 and a=-3
hope that helps
