Answer: 3
Step-by-step explanation:
y intercept just means plug in x = 0 to the equation and solve for y.
so
y = -4*0^2-0+3
y = 3
Answer:
The amount is actually 120
Step-by-step explanation:
Answer:
78
Step-by-step explanation:
1. Find the values at 2 and 5: 3^2 = 9 3^5 = 243
2. Subtract to find the difference 243-9 = 234
3. Divide by the interval : 234/(5-2) = 78
Answer:
y = 15x + 50
Step-by-step explanation:
We set out by finding the slope
the two points give are (15,275) and (25,425)
Slope m is;
y2-y1/x2-x1 = (425-275)/25-15 = 150/10 = 15
So the equation is like;
y = 15x + b
To get b, let us use the point (15,275)
We have
275 = 15(15) + b
b = 275-225
b = 50
So the equation is;
y = 15x + 50
Answer: S = P600 × n
Step-by-step explanation:
Amount earned per day = P600
Number of days used = n
The total salary s, will be the value of p600 multiplied by n. This will be:
= P600 × n
Therefore, the function regarding the total salary, s will be: P600 × n
