If we substitute equation (2) into (1) then we have the equivalent equations; y = 5 - x and 5 - x = 9x².
<h3>What is a mathematical equation?</h3>
An equation must contain two sets of variables, the independent variable and the dependent variable separated by the equality sign.
In this case, the original system of equations are; y = 9x² and x + y = 5. It the follows that, if we substitute equation (2) into (1) then we have the equivalent equations; y = 5 - x and 5 - x = 9x².

A bags of daffoil costs $ 17
Step-by-step explanation:
Packages of tulip buls = t
Bags of daffoil = d
Process
1.- Write an equation for each girl
Castel 12t + 11d = 295 (1)
Krystal 6t + 4d = 122 (2)
2.- Solve the equation by elimination
12t + 11d = 295
- 2( 6t + 4d = 122)
12t + 11d = 295
-12t - 8 d = -244
0 + 3d = 51
d = 51 / 3
d = $ 17
3.- Find the value of t
6t + 4(17) = 122
6t + 68 = 122
6t = 122 - 68
6t = 54
t = 54 / 6
t = $ 9

Answer:
1.5
Step-by-step explanation:
First, find the mean (average) of the data set.
mean = (x1 + x2 + ...)/N
where x1, x2, ... are the data points, and N the total amount of data points.
mean = (7 + 2 + 4 + 3)/4 = 4
Then, mean absolute deviation is computed as follows:
MAD = (|x1 - mean| + |x2 - mean| + ...)/N
MAD = (|7 - 4| + |2 - 4| + |4 - 4| + |3 - 4|)/4
MAD = (3 + 2 + 1)/4 = 1.5
