Answer:
f(x)= 3x + 1
Step-by-step explanation:
Let's set the unknown variable as b, since it's a linear equation.
Using the point given (-3, -8), we can find b by plugging in the known numbers and solving.
-8 = -3 (3) + b
-8 = -9 + b
b = 1
If you want, you can check it by forming the complete equation and plugging in -3.
f(x)= 3x + 1
f(-3) = -9 + 1
f(-3) = -8 = -8
I hope this helped!
Answer:
C $0.40
Step-by-step explanation:
to find how much one pound of potatoes is, you have to divide the the cost of the bad by the number of pounds ($3.98 divided by 10 pounds)
$3.98 : 10 = $0.398 = $0.40
Steps:
1. Do a proportion
X/62= 81/100
2. Do 81 times 62 which is 5,022
3. Now divide 5,022 by 100 which is 50.22
4. Your answer is 50.22
