Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,
Answer:
20bags+$30
Step-by-step explanation:
The side lengths on the new dilated rectangle will be 30cm and 16cm
<h3>How to calculate dilation</h3>
Given the following parameters
- Length = 8cm
- Breadth = 15cm
If the length and breadth are dilated by a factor of 2, hence the new dimansion will be:
New length = 2(15) =30cm
New width =2(8) = 16cm
Hence the side lengths on the new dilated rectangle will be 30cm and 16cm

a) 13
b) 0
c) 1
d) 4/9
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)
Given:
f(x)= 2x+3 and g(x)= x²-5.
a) (f+ g)(3)
= f(3)+ g(3)
= 2(3)+3 + (3)²-5
=6+3+9-5
=13
b) (f-g)(4)
= f(4)- g(4)
= 2(4)+3 - (4)²+5
=8+3-16+5
= 0
c) (fg)(-2)
= f(-2)*g(-2)
=[ 2(-2)+3][(-2)² -5 ]
=(-1)(-1)
= 1
d) (g/f)(3)
= g(3)/f(3)
= 3²-5/ 2(3)+3
= 4/9

Answer:
2
Step-by-step explanation:
Step 1 write the equation: y=3x-1
Step 2 Plug 1 in: y=3(1)-1
Step 3 Multiply 3 and 1: y=3-1
Step 4 Subtract 3 from 1: y=2
