Answer:
The expression for the total cost is x = 19.99 + 0.99n .
Step-by-step explanation:
Let us assume that the total cost be x.
As given
Sophia pays $19.99 membership fee for an online music store.
If sophia purchases n songs for $0.99 each .
Than the expression becomes
Total cost = Membership fee + Cost of n songs
x = 19.99 + 0.99n
Here n represented the number of songs.
Answer:
y = x + 1
Step-by-step explanation:
The line y = x goes through the origin, and forms a perfect 45 degree angle with the x axis.
This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.
Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so
y = 1x + 1 = x + 1
y = x + 1

Let's solve your inequality step-by-step.
3 ≤ 7 + g
Step 1:Simplify both sides of the inequality.
3 ≤ g + 7
Step 2: Flip the equation.
g + 7 ≥ 3
Step 3: Subtract 7 from both sides.
g + 7 − 7 ≥ 3 − 7
g ≥ −4
Answer:
g ≥ −4
