Answer:
y = 1/5x + 2 1/5
Step-by-step explanation:
first find the negative reciprocal slope of 5x + y = 30 because perpendicular lines have negative reciprocal slope:
=> y = -5x + 30, negative reciprocal of the slope -5 is 1/5
substitute the new slope 1/5 and the coordinate (9, 4) into the equation: y = mx + b to solve for b
=> 4 = 1/5(9) + b
=> 4 = 9/5 + b
=> b = 2 1/5
plug in the slope 1/5 and b = 2 1/5 into the equation: y = mx + b
=> y = 1/5x + 2 1/5
Answer: A-5
Step-by-step explanation:
Jestina has A apples
she gave 5 away
so she has 5 fewer apples than she had before
so A-5 is the amount of apples she has now
Answer:
75
Step-by-step explanation:
For this, you need to solve a proportion-
3.4 x
----- = -----
1.8 39.75
3.4*39.75=135.15
135.15/1.8= 75.0833.....
75.0833.. is rounded to 75
X = -1/2 (negative)
y = - 1.8 (negative)
so It's in Quadrant 3
Answer:
One solution
Step-by-step explanation:
y = 2x – 5. –8x – 4y = –20. one solution: (–2.5, 0)
