Answer:
y = −3x − 23
Step-by-step explanation:
The equation of the line in the slope-intercept form is y= x/3 + 6.
The slope of the perpendicular line is negative inverse: m = −3.
So, the equation of the perpendicular line is y = −3x + a.
To find a, we use the fact that the line should pass through the given point:
−2 = (−3) ⋅ (−7) + a.
Thus, a = −23.
Therefore, the equation of the line is y = −3x − 23.
Answer: y =−3x − 23
Answer:
3x+7
Step-by-step explanation:
Answer:
x = 25°
Step-by-step explanation:
3x + 2x + x + 30° = 180°
6x + 30° = 180°
6x = 150°
x =25°
=> 3x = 25 * 3 = 75°
=> 2x = 25 * 2 = 50°
=> x + 30° = 25° + 30° = 55°
11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.
You can pick a symbol, maybe m or z to be the symbol.
