Answer:
Step-by-step explanation:
perp. -5
y + 7 = -5(x - 4)
y + 7 = -5x + 20
y = -5x + 13
Answer:
d
Step-by-step explanation:
1.75 ( would be the coffee) + 1.50d (donuts each but an unknown quantity)
total amount must be less than $37 dollars
Your answer would be 37.00 - 1.75 = 35.25 cents
35.25 / 1.50 = 23.5 donuts - you can not purchase a half of a donut so you can buy 1 coffee and 23 donuts for $36.25
Answer:
y+4=-3(x+0) or y=-3x-4
Step-by-step explanation:
so you have to make it in form y=mx+b
that would be y=1/3x-2/3
for a perpendicular line, you would need to find the opposite reciprocal of the slope
3/1 or 3 would be the reciprocal, so to make it opposite would be -3
So it would be y-y1 = m(x-x2)
fill it in with the coordinates (0,-4)
y+4=-3(x-0)
to get it to slope intercept form you have to simplify, and after that you get y=-3x-4
3/4 X 10= $7.50
Because 3/4 is 75%, 10 is the original price. And 75% times 10 is 7.50<span />
Answer:
y = - 3x -11
Step-by-step explanation:
(x₁ , y₁) = (-2 , -5) & m = -3
y - y₁ = m (x - x₁)
y - [-5] = (-3)(x -[-2])
y + 5 = (-3)(x + 2)
y + 5 = -3x - 6
y = -3x - 6 - 5
y = - 3x -11
