The answer is x = -1.3333
Answer:
It’s a
Step-by-step explanation:
Because it rotates in a 90 degree angle
Answer:
b. 7x3 + 9x2 - 3x - 8
Step-by-step explanation:
Write the problem as a mathematical expression.
(4x3+6x2+2x−3)+(3x3+3x2−5x−5)
Remove parentheses.
4x3+6x2+2x−3+3x3+3x2−5x−5
Add 4x3
and 3x3
.
7x3+6x2+2x−3+3x2−5x−5
Add 6x2
and 3x2
.
7x3+9x2+2x−3−5x−5
Subtract 5x
from 2x
.
7x3+9x2−3x−3−5
Subtract 5
from −3
.
7x3+9x2−3x−8
(x,y) or
(x,f(x))
so just plug the first value in and see if yo get the 2nd value
A. when x=-2, then is f(x)=48?
remember, x^-m=1/(x^m)
3(1/4)^-2=3/((1/4)^2)=3/(1/16)=3*16=48
true
B. x^0=1
so 3(1/4)^0=3(1)=3
true
C. when x=2
3(1/4)^2, 3(1/16), 3/16
true
D. 12
das is obviously false but anyway
3(1/4)^12=3(1/big number)=3/big number=small number but not zero
answer is A,B,C
