Answer:
3y-4x=9
Step-by-step explanation:
using y-y1/ x- x1=m
y-1/x--3=4/3
y-1/x+3= 4/3
3(y+1)=4(x+3)
3y+3= 4x+12
3y-4x=12-3
3y-4x=9
Its not exponential
Note that each new Y values is obtained by adding 4 to previous Y value
Answer:
Hey!
Your answer is that the motorbike will cost $1,275 after the 15% discount
Step-by-step explanation:
15% of $1,500 is $225 so we minus this value away from $1,500 which gives us $1275!
HOPE THIS HELPS!!
We can use these variables:
A = number of ounces for solution A
B = Number of ounces for solution B
A + B = 20
Now, we can use decimal conversions.
0.65A + 0.80B = 0.70(120)
Next step: We substitute A into 120 - B to show their relationship.
0.65(120 - B) + 0.80B = 84
Now onto the next equation:
78 - 0.65B + 0.80B = 84
0.80 - 0.65 = 0.15, so…
0.15B = 84 - 78
0.15B = 6
B = 6 divided by 0.15
B = 40 ounces
To find A, we can simply plug B into the starting equation.
A = 120 - 40
A = 60 ounces
Your final answer: The scientist should use 60 ounces of solution A and she should use 40 ounces of solution B. Yeah
-2b + 7 > 27.5
- 2b > 27.5 - 7
- 2b > 20.5
b < - 10.25
