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 )
y = 2x + 3 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
Note this line passes through (0, 4) ⇒ c = 4
y = 2x + 4 ← equation of parallel line
A. He will have saved $25.
B. He will have saved $150.
C. He will have saved $500.
He will have saved $50.
The answer is D
This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.
The proportion is as follows:
50/5 == 500/x
x is equivalent to the amount of money he has saved
You can cross multiply to get the following equation:
50x == 2500
To isolate x, you must divide both sides by 50, giving you an answer of:
x = 50
This is the same as option D

Answer: j/2+7= the amount his brother has
Step-by-step explanation:
I'm going to do an example equation, so let's pretend j=30
Step 1: Divide the jelly beans in half (by 2)
30/2=15
Step 2: So now they each have 15 jellybeans, but if Jarrett gives his brother 7 jellybeans...
15+7= 22
Answer:
Step-by-step explanation:
j = jelly beans
Jarrett splits his bag of j jelly beans into two equal piles
so now we have two equal piles of the jelly beans
½j and ½j
and gives one pile to his brother
so right now the brother has
½j
He then gives his brother seven more beans
we add 7 to our equation and now
this is the algebraic expression that represents the number of beans the brother has:
