Answer:
1: something because you didn't give another number. For example, 1:2 is 1 golf ball to 2 golf tees. A ratio is one thing comparing to another. Hope this helps! I learned this in 6th grade. Brainly if so!
Step-by-step explanation:
Answer:
1: 47
2: 19
3: 7
4: 11
5: 31
Step-by-step explanation:
input the number next to F where x is. example: f(-2)= 8(-2)^2-4(-2)+7 and then solve using PEMDAS giving f(-2)=47 and so on.
A proportion<span> is a name we give to a statement that two ratios are equal. It can be written in two ways: two equal fractions, or, using a colon, a:b = c:d.</span>
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.
2 is 42 but i’m not sure about one
