Answer:
it would be Y= -2x+4
Step-by-step explanation:
To begin, we know that the b value is 4, because that is the x-intercept that is information given, so we can atomatically put that in.
Next we need to find the m value, which can be found by knowing the rules of a perpendicular eqution. to change it you must change the 1/2 and flip the equation and change the signs
soooooo 1/2 would change into 2/1 which is 2 and we would addd the negative sign so
Y=-2x+4
Answer:
y = -5/4x + 6
Step-by-step explanation:
Since the line we are supposed to find is parallel to y = -5/4x - 5 that means they are going to have the same slope. The line we are looking for is of the following type: y = -5/4 x + b
Since it passes through the point (-8,4):
4 = -5/4 * (-8) + b <=>
4 = -2 + b <=>
4 + 2 = b <=>
b = 6
Hence the line is going to be: y = -5/4x + 6
Answer:
1.25
Step-by-step explanation:
90=6x+3x
90=9x
90/9=x
10=x
3x=3*10=30
6x=6*10=60
hope this helped
