Answer:
B. x = 5 and y = -13
Step-by-step explanation:
Equating real parts, we have ...
... x + 4 = 9
... x = 9 - 4 . . . . subtract 4
... x = 5
___
Equating imaginary parts, we have ...
... yi +9i = -4i
... yi = -4i -9i = -13i . . . . subtract 9i
... y = -13 . . . . . . . . . . . divide by i
Hey there! :)
Answer:
a. 3
b. -22
c. -2
d. -2
e. 5a + 8
f. a² + 6a + 3
Step-by-step explanation:
Calculate the answers by substituting the values inside of the parenthesis for 'x':
a. f(1) = 5(1) - 2 = 3
b. f(-4) = 5(-4) - 2 = -22
c. g(-3) = (-3)² + 2(-3) - 5 = 9 - 6 - 5 = -2
d. g(1) = 1² + 2(1) - 5 = 1 + 2 -5 = -2
e. f(a+ 2) = 5(a+2) - 2 = 5a + 10 - 2 = 5a + 8
f. g(a + 2) = (a + 2)² + 2(a + 2) - 5 = a² + 4a + 4 + 2a + 4 - 5 =
a² + 6a + 3

Answer:
1. stop spaming
Step-by-step explanation:
ok so you ha- :L u have 251 plus...
it is easy :D it is 429 then equals 680 :D
i think.
In the domain are the values of x
in the range are the values of y
if you substitute in the values of the domain x=0, x=1, x=3, x=5, x=6 in the function f(x)= y=4-4x you will get the value from the range y=4, y=0, y=-8, y=-16, y=-20
and so on...
Answers:
first f(x)=4-4x
second f(x)=5x-3
third f(x)=-10x
fourth f(x)=(3/x)+1.5
