Write a point-slope equation that must pass through the points (1, 4) & (4, 10).

1 answer:

5 0

Point slope uses one point and the slope. We’ll use (4,10)
Y - 10 = 2 • (x - 4)
But it can also be
Y - 4 = 2 • (x - 1)
Whichever you prefer to use

He puts 1/4 of the treasure to aside for himself he gives 1/2 of what is left to his friend bill he shares 2/3 of the remaining

Andrej [43]

Answer:

24 bars of treasure

Step-by-step explanation:

You just need to do the opposite in order to find the total value since you divided the treasure up we need to multiply the treasure “back”.

3 buried bars is equal to 1/3 of the remaining treasure. Multiply by 3 to get 3/3 or 100% of buried and crew portion. So we now have 9 bars. Then multiply by 2 to get 100% of what was given to bill, crew and buried. We now have 18 bars. Then we know that we took 1/4 for ourselves so that means 18 bars represents 3/4 of the treasure. So when we look at factors of 18 we find that 3 x 6 = 18 and 4 x 6 = 24 so we conclude that we had 24 bars of treasure before the split.

Melanie eats 1.5 pounds of cereal each week. Which model below best represents the number of pounds of cereal she eats in .5 wee

Katena32 [7]

For this case, the first thing we must do is define a variable.
We have then:
x: number of weeks
y: amount of cereal that Melanie eats
We now write the function that models the problem:
$y = 1.5x
$
Then, for 5 weeks we have:
$y = 1.5 (5)

y = 7.5 pounds$
Answer:
A model that best represents the number of pounds of cereal she eats is:
$y = 1.5x
$
For 5 weeks we have:
$y = 7.5 pounds$
