Answer:
y = 2x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (- 2, 0 ) into the partial equation
0 = - 4 + c ⇒ c = 0 + 4 = 4
y = 2x + 4 ← equation of line
Equation: 50 is greater than or equal to 45 + .5(x)
x = amount of pictures you can send without going over your budget
subtract 45 from both sides. you are left with: 5 is greater than or equal to .5(x)
multiply both sides by 2. you are left with: 10 is greater than or equal to x
Answer: 10 is greater than or equal to x
Answer:
Step-by-step explanation:
Combine 2a^3+5a-7 and 5a^2-6a+12.
Rewrite this so that the second expression is beneath the first:
2a^3+5a-7
5a^2-6a+12
Combine like terms. The highest order term is 2a^3:
2a^3+0a^2 +5a-7
+5a^2 - 6a+12
----------------------------
2a^3 + 5a^2 - a + 5 (answer)
Note how these terms are in descending order by power of a.
