Answer:
Step-by-step explanation:
x²+3x+2=0
x²+x+2x+2=0
x(x+1)+2(x+1)=0
(x+1)(x+2)=0
x=-1,x=-2
so B
Answer:
122.5
Step-by-step explanation:
take 8.75 multiply it by 2 then multiply it by 7 to get your answer 122.5
4 1/3
Okay, I know fractions are scary, but we can do this alright?
First, you see the whole number on the side? Get that first.
10- 5 = 5
now we have 5 left and a scary fraction. Don't panic, let's do this. We know 1 is 3/3. 1 can be anything as long as the number on top and the number at the bottom are the same then it would be one.
So 3/3 is one then we can subtract:
3/3 -2/3 .
We subtract the top number and leave the one at the bottom the same.
3-2 = 1
Then we have 1/3.
As you took one away from the 5, it becomes a 4 and you put back the left over, 1/3.
Then you answer will be :
4 1/3
64 lb = 29.0299 KG
Rounding to the nearest hundredth, it's 29.03 KG
The graphed function, F(x), has a value greater than 0 over the intervals (-0.7, 0.76) and (0.76, ∞) . F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞) is the correct statement [Fourth choice].
About a Graphed Function
The function graph of an object F stands for the set of all points in the plane that are (x, f(x)). The graph of f is also known as the graph of y = f. (x). The graph of an equation is thus a specific example of the graph of a function. A graphed function is a function that has been drawn out on a graph.
It is evident from the attached graph that the supplied function exceeds 0 for the following range:
-0.7 < F(x) < 0.76
And, 0.76 < F(x) < ∞
As a result, the intervals for which the given graphed function, F(x) is greater than 0 are as follows,
(-0.7, 0.76) and (0.76, ∞)
