Answer:
y= 4x+3
Step-by-step explanation:
To write your equation, solve for the slope.
(y2-y1)/ (x2-x1)
Find two coordinate points from the table.
(0,3) (1,7)
(7-3)/ (1-0)= 4
m=4
Use point-slope equation to find your equation.
(y-y1)=m(x-x1)
(y-3)=4(x-0)
y-3= 4x
y= 4x+3
The value of 28 tens is 280 because a ten is literally 10 you only multiply 28*10= 280 So the value of 28 tens is 280.
Thank You!
F(3)=-18
You just replace x for three for your equation and then use Ofer of operations to solve it.
So f(3)= 21+ 2(3)-5(3)^2
The exponent goes first: f(3)= 21+ 2(3)-5(9)
Next is multiplication: f(3)= 21+ 6-45
Now add: f(3)= 27-45
Finally subtract: f(3)= -18
Hope this helps!
Answer:
₱445
Step-by-step explanation:
₱18.50(x)
x = number of pineapples purchased
₱18.50(80) = ₱1480
80 - 3 = 77
₱25.00(z)
z = number of pineapples resold.
25.00(77) = ₱1925
₱1925 = ₱1480 = ₱445
