5x + 10y = 360
y = 2x + 1

5x + 10*(2x + 1) = 360
5x + 20x + 10 = 360
25x = 350
x = 14

y = 2x + 1
y = 2*14 + 1
y = 29

Derek has 14 nickels and 29 dimes

Patrice goes to fishers candy shop with the price of gummy candies modeled by the equation y=5/2x where x is the amount of gummy
icang [17]

Answer:

You need to put the question, but I'll try to help as much as I can without the question. y=5/2x, if you put the amount of gummy candy in lbs in the x's place, and you multiply the amount by 5/2, you will get the price.

2. Graph the function y=x^2+2x-3 . Draw a chart to show at least three ordered pairs that are on the graph.
lidiya [134]
You'd have to draw a table of x and y values first to be able to graph.
Step 1: Pick any number for x. Let's pick 2.
Step 2: Plug in 2 into the equation: y = 2^2 + 2(2) - 3
Step 3: Solve for y: 4 + 4 - 3 = 5
Step 4: So the point (ordered pair) would be (x, y) ⇒ (2, 5). You can plot that on the graph.

Follow these steps 2 more times to get at least three ordered pairs.

Make sure you have enough points to know where the graph curves, then you can connect the dots and now there you have a graph and chart :)
