Answer:
-1.5x + 70
Step-by-step explanation:
Total money he takes while going to the fair = $90
Money he spends to enter the fair = $5
Money he spends on food =$15
Total he spent now is given by
Now, he spend on rides at the fair i.e. 1.50 per ride .
Let the number of rides be x
So, cost incurred on rides = 1.5x
So, the spending money can be expressed as
Now, remaining money left to him after spending on x rides too is
Let f(x) denotes the function used to determine the money he has left over after rides .
So it becomes
f(x) = 70 - 1.50x
f (x) = -1.50x +70
Nothing to "solve" here. Just graph this absolute value function.
Note that if x=2 we get y = -4. Thus, (2,-4) is the vertex. Plot this point.
Now, starting from (2, -4), draw a line at a 45 degree angle to the horizontal.
Then draw a corresponding line on the other side of the y-axis. You're done!
Answer:
Each weighs about 0.25kg
Step-by-step explanation
This is because since 15 oranges = 3.75, you should do 3.75 / 15 which gets you 0.25.
2(2d+4)=-3(d+2)
4d+8=-3d-6
4d+3d=-6-8
7d=-14
d=-14/7
d=-2
3 (2x + 4y - y) Combine like terms (4y and -y)
3 (2x + 3y) Use the Distributive Property [(3 · 2x) + (3 · 3y)]
6x + 9y
