4y=-5x+15
y=-5/4x+15/4
y-1/2=4/5(x-1/2)
y-1/2=4/5x-2/5
y-5/10=4/5x-4/10
y=4/5x+1/10
Answer: where’s the diagram
Step-by-step explanation:
Answer:
y - 7 = -1/4(x-4)
Step-by-step explanation:
point slope is y-y₁=m(x-x₁)
(4, 7) and (8, 6)
I like to put it in the slope-intercept form first
so... 6 - 7/ 8-4 = -1/4 (slope)
6 = -1/4(8) + b
6/(-2) = -2/(-2) + b
-3 = b
so... y=-1/4x + -3
plug it in to point slope form
y - 7 = -1/4(x-4)
hopefully that made sense :)
I'm assuming that each price copied twice, since 5.225.22 isn't a number.
To find the percent, divide the tip by the meal cost:
5.22 ÷ 29 = 0.18 = 18%
Jerry left an 18% tip.
To find the total cost of the meal, add the tip and the meal cost:
5.22 + 29.00 = 34.22
The total cost if the meal, including tip, was $34.22.
