To answer this, you will determine what fraction of the original rocks are silver by using the information about the other two colors.
If 2/3 of them area purple, than 1/3 are not.
If 3/4 of the remaining 1/3 is blue, than 3/4 x 1/3 = 3/12 of then are blue.
2/3 are purple, 3/12 of them are blue, the remaining is silver,
1 - 2/3 - 3/12
1 - 8/12 - 3/12 = 1/12
1/12 of the rocks are silver. If 3 are silver, write an equation that needs solved.
1/12r = 3
r = 36 rocks
There were 36 space rocks in total.
Literally a question similar to the one before.
c=m*325, so if m=7:
-> c = 7 * 325
=> c = 2275 chairs
Answer:
16a^2+5
Step-by-step explanation:
The constant of proportionality would be "4" ... proportional relationships are in the form of y = kx.. so in your ordered pairs, you can see that to get the 'y' coordinates you would have to multiply the 'x' coordinates by 4.
Answer:
(1, -3)
First option
Step-by-step explanation:
The minimum point on the graph is also the <u>vertex</u>.
The quadratic function equation is given in <u>vertex form</u>, which is 
Using this equation, the vertex is (-h, k).
Whatever number you see for "h", find its opposite negative/positive. That will be the x-coordinate of the vertex. The y-coordinate for the vertex is the same as "k", keeping the negative and positive.
In f(x) = (x - 1)² - 3 using (-h, k) is:
h = -1 => -h = 1
k = -3
Therefore the vertex is (1, -3).
