Step-by-step explanation:
1. No: angles add to more than 180 deg.
2. Yes: each side's length is between the sum and difference of the lengths of the other two sides.
3. No: not every side's length is between the sum and difference of the lengths of the other two sides.
4. Yes: for example, place the 50 deg angle between the two given sides. Another side will then make the triangle.
5. Yes: for example, use 3 cm as the short leg in a 30-60-90 right triangle.
Answer:
the first one listed (y = - + 4)
Step-by-step explanation:
a 0 at an x-intercept means that when plugging in that number, you get a 0 as a y-value.
So, the easiest method to use is to plug x=2 into each equation listed, because we can see that (2,0) is a point on this graph
if y= - + 4
y = -2² + 4
y = -4 + 4
y = 0
This means that this graph has corresponding real zero(s) to the function y= + 4
(I chose which graph to test by looking to see which option seemed right)
I'm pretty sure that is a function for a parabola, so it is probably a quadratic function. I'm not 100% sure though.
Answer:
Subtract four on both sides.
Step-by-step explanation:
When we solve for x, we do the reverse of PEMDAS. The last letter is S, so we subtract. There is no subtraction, so we move to A for addition. There is addition, the plus 4, so to get rid of it, we subtract 4 on each side.
Answer:
6,300kg=6,300,000grams
multiply 6,300 and 1,000 to get 6,300,000
