Answer:
<h2>
y = -4/9</h2>
Step-by-step explanation:
Given the system of equations y = 3/2 x − 6, y = −9/2 x + 21, since both expressions are functions of y, we will equate both of them to find the variable x;
3/2 x − 6 = −9/2 x + 21,
Cross multiplying;
3(2x+21) = -9(2x-6)
6x+63 = -18x+54
collecting the like terms;
6x+18x = 54-63
24x = -9
x = -9/24
x = -3/8
To get the value of y, we will substitute x = -3/8 into any of the given equation. Using the first equation;
y = 3/2x-6
y = 3/{2(-3/8)-6}
y = 3/{(-3/4-6)}
y = 3/{(-3-24)/4}
y = 3/(-27/4)
y = 3 * -4/27
y = -4/9
Hence, the value of y is -4/9
The answer is false, they are parallel not perpendicular
Answer:
4
Step-by-step explanation:
The median is the middle number when the list is sorted from least to greatest or greatest to least.
We make this list to get 2,3,4,5,8 or 8,5,4,3,2 and the middle number in both lists is 4.
70 is 25% of 280. 25% is the same as 1/4 and 1/4 of 280 is 70
