Hello from MrBillDoesMath!
Answer: y = 2x - 7
Discussion:
Divide both sides of the equation by 2:
2y /2 = (4x-14)/2 = 4x/2 -14/2
or
y = 2x - 7
Thank you,

Answer:
43.6%
Step-by-step explanation:
500-282=218
218/500=0.436
0.436=43.6%
Based on the given summation notation, the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n
<h3>How to determine the summation expression?</h3>
The expression is given as:
43Σn=1(3+9n)
As a general rule, if a summation notation is represented using the following expression
Σ(a + bn)
The equivalent expression of the above summation notation is
Σa + bn
Where the variable a is a constant in the expression
This means that:
Σ(a + bn) = Σa + bn
Using the above equation as a guide, we have the following equivalent equation
43 Σ n=1 (3+9n) = 43 Σ n=1 3 + 43 Σ n=1 9n
Hence, based on the given summation notation; the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

Answer:
The expression Barak could use to find the amount he will spend to feed his pet lizards for one day = Number of pets × number of crickets per pet × cost of each crickets
Step-by-step explanation:
Pet lizards = 4
Each lizard eats 5 crickets
4 pet lizards will eat = 4 × 5 crickets
= 20 crickets
A cricket = 12 cents
That is, $0.12
Cost of 20 crickets = 20 × $0.12
= $2
The expression Barak could use to find the amount he will spend to feed his pet lizards for one day
= Number of pets × number of crickets per pet × cost of each crickets
= (4) (5) (0.12)
= $2.4
