Answer:
x^2-3x=4
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4)+1(x-4)=0
(x+1)(x-4)=0
x=-1,4
x- intercepts in the point (-1,0) and (4,0)
Step-by-step explanation:
A cuz of how its functions
and D cuz of how it uses the numbers i guess
Answer:
a=3
Step-by-step explanation:
5=4a-7
add 7 on both sides
5+7=4a(-7+7)
12=4a
Now divide 4 on both sides
a= 3
PLEASE GIVE BRAINLISET
1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3
experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity
2. experimental considered previous trials and theoretical did not
3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16
Answer:
120
Step-by-step explanation:
Is means equals and of means multiply
