Answer:
When k(x) is 2x² - 5x + 3, k(-3) = 36.
Step-by-step explanation:
k(x) = 2x² - 5x + 3
Substitute the input of x.
k(-3) = 2(-3)² - 5(-3) + 3
Square -3.
k(-3) = 2(9) - 5(-3) + 3
Multiply 2 and 9.
k(-3) = 18 - 5(-3) + 3
Multiply -5 and -3.
k(-3) = 18 + 15 + 3
Add 18 and 15.
k(-3) = 33 + 3
Add 33 and 3.
k(-3) = 36.
Answer:
The president is using the mode because it is the most obvious answer. The fans are using the iconic mean which is the middle number of the data set. They can be different because different people think of numbers differently.
Step-by-step explanation:
Answer:
y = -7; x = 4
Step-by-step explanation:
x - 7y = 53
x = 7y + 53
-4x - 5y = 19
-4(7y + 53) - 5y = 19
-28y - 212 - 5y = 19
-33y = 231
-11y = 77
y = -7
x - 7(-7) = 53
x + 49 = 53
x = 4
Fifty-nine hundredths is .59
Answer:
x=2 and y=3
Step-by-step explanation:
This is a system of equations that you would solve by substitution.
Start by solving for x by plugging in the value of y:
x + 2(x+1) = 8,
Then simplify:
3x = 6 / x = 2
Now plug the known value of x into the first equation:
y = (2) + 1
Simplify,
y = 2
I hope this helps!
