Without drawing a graph find the intercepts of each line. y+5=–2x
1 answer:
Answer:
see explanation
Step-by-step explanation:
The intercepts are where the line crosses the x and y axes.
To find the x- intercept ( where the line crosses the x- axis) let y = 0 in the equation and solve for x, that is
0 + 5 = - 2x
5 = - 2x ( divide both sides by - 2 )
x = - = - 2.5 ← x- intercept ⇒ (- 2.5, 0 )
To find the y- intercept ( where the line crosses the y- axis ) let x = 0 in the equation and solve for y, that is
y + 5 = 0 ⇒ y = - 5 ← y- intercept ⇒ (0, - 5 )

Answer:
1. Typed question: 175 green eggs
2. Attached: 22 tables
Step-by-step explanation:
For the question you typed down, it is a ratio and proportion problem. You need to solve for the ratio proportional to the first ratio given.
4 blue eggs are filled for every 7 green. This means that the ratio between blue eggs and green eggs is 4:7.
Now yo need to figure out a ratio proportional to 4:7 if 100 blue eggs were filled. Below is how this is set up:
Now let's solve for x:
For your attached problem:
You have a total of 175 people, you need to figure out how many round tables you need if here are 8 chairs for each table You just need to divide the number of people by the number of chairs per table.
175 ÷ 8 = 21.9 tables
Now since you cannot have half a table, you round up to the nearest whole number. (we round up because you need to make sure that all of them are seated)
21.9 ≅ 22 tables.
