Answer:
y = -2x + 5
Step-by-step explanation:
Slope-intercept form: y = mx + b
The slope of the line, m, is -2 because the line shows a negative trend and moves right 1 unit every time a point moves down 2 units.
The y-intercept, b, is 5 because the line crosses that number once on the y-axis.
Answer:
The correct option is:
100 + 0.8(x - 100) = 250
Step-by-step explanation:
We are given that:
We know that a department store gives 20 % off the portion of the bill that is over 100 dollars.
Total bill is 250 and x is the amount of money she would have spent without the promotion.
The cost to which the discount applies is 0.8 ( x - 100 ).
<em>Finally the equation we get is 100 + 0.8 (x - 100) = 250.</em>
The correct answer is C:$76.05. Tim would make 135.42 in three months and the total (221.47) minus 135.42 equals 76.05.
Answer:
-37/5= y
x=11/5
Step-by-step explanation:
4x-3y=31
-3y=-4x+31 regroup it to match the other
-2 y=(2x-3)(-2) multiply by -2 to get -4x
-3y=-4x+31
-2y=-4x+6 adding
-5y=37 divide
-37/5= y
4x-3(-37/5)=31
x=11/5
