Answer:
Step-by-step explanation:
The negative out front only tells us which way the parabola will open. That means that the first one will open upside down, since it's got a negative out front. The value of the number that serves as the leading coefficient (the number stuck to the x-squared) determines how steep or wide-open the parabola's shape is. The leading coefficient in the first one is a 1, so it opens up exactly as wide as its parent graph does. The leading coefficient in the second one, a 2, means that the parabola will be skinnier or narrower than its parent. If the leading coefficient is greater than 1, the parabola will be narrower than its parent; if the leading coefficient is greater than 0 but less than 1, the parabola will open wider than its parent.
X=4 so
2x=8
2x4=8
8+31 =39
Answer:
B
Step-by-step explanation:
.4 as we know can also be handled as .40, as the zero helps us determine the difference in value. 50%, though it is a percentage, can be put into decimal form. That would be .5, or again, we could add a zero to help us out, which would make it .50. As of right now, .4 is less than 50%. 3 and 13 are whole numbers, so they do not really need deep observation, except that 3 is less than 13. That would make the order of number from least to greatest .4, 50%, 3, and 13.
