Step-by-step explanation: how this helps :)
Answer:
The model is made in a<u> 1:40 ratio
</u>
Step-by-step explanation:
How many times is 4 multiplied to be equal to 160?
4(x) = 160
X = 160 / 4
<u>X = 40</u>
The proportion, rate, and ratio are almost the same.
They represent the correspondence between the parts and the whole since they all express a binary relationship between the quantities, that is, objects, people, tablespoons.
If the ratio is 1: 2 it could be read that for every 1 there are 2.
For example 1: 2 cups; For every cup of something there are 2 cups of something else.
In this case, 1:40; For every inch of the model, there are 40 feet in the playground.
Answer:
y = -3x - 11
Step-by-step explanation:
y - y1 = m(x-x1)
y - (-1) = -3(x-(-4))
y + 1 = -3(x+4)
y + 1 = -3x -12
y = -3x - 11
