Answer:
D
Step-by-step explanation:
sqrt_{4}(81)^5=(81^(5))^(1/4)=81^(5/4)
Answer:
5; -22
Step-by-step explanation:
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional.
Given the following data;
Input: 1 2 3 4 n
Output: -10 -13 -16 -19
For an input variable of 1, 2, 3, 4; the output variable is -10, -13, -16, -19 respectively.
To find the value of n;
We can deduce that the input is increasing by a value of 1.
Thus, n = 4 + 1 = 5
For the output;
We can deduce that the output is increasing by a value of -3.
Thus, the next output = -19 + (-3) = -22
Answer:
x=3, y =2
(3,2)
Step-by-step explanation:
y =2/3 x
y = -2/3 x +4
set them equal to each other y=y
2/3 x = -2/3 x + 4
add 2/3 x to each side
2/3 x+2/3x = -2/3x + 2/3 x + 4
4/3 x = 4
multiply by 3/4 on each side to clear the fraction
3/4 * 4/3 x = 3/4 * 4
x = 3
now we need to find y
y = 2/3 x
y = 2/3 * 3
y =2
