Answer:
see explanation
Step-by-step explanation:
(a)
The angles are vertical and congruent, that is
x - 10 = 125 ( add 10 to both sides )
x = 135
-------------------------------------------------
(b)
Supplementary angles sum to 180°
The angles are in the ratio 2 : 3 = 2x : 3x ( x is a multiplier ), then
2x + 3x = 180
5x = 180 ( divide both sides by 5 )
x = 36
thus
2x = 2 × 36 = 72
3x = 3 × 36 = 108
Then the 2 angles are 72° and 108°
Answer:
A.
Step-by-step explanation:
the other ones don't make sense due to the division problem
the R in the answer means remainder
so he has 25 remaining or leftover plants
I hope this helps :)
Answer: B) 27 grams in all
Step-by-step explanation:
Given: The weight of each bright blue poisonous frog = 3 grams
By using the multiplication operator (x)
Then, the weight of 9 such frogs = 9 x (Weight of each frog)
⇒ The weight of 9 frogs = 9 x 3 grams
⇒ The weight of 9 frogs = 7 grams
Therefore, the correct option is B) 27 grams in all
Domain is basically all of x values.
Range is basically all of y values.
That means if you want to find the domain, you can check from the coordinate-x and if you want to find the range, you can check from the coordinate-y.
As you can see in the graph, there are the colored and non-colored dot. Both present the inequality symbol. If it's a colored circle/dot then it's either ≤ or ≥ but if it is non-colored dot then it's either > or <
From the graph, we can say that the minimum value is at -4 when x = -5
and there is no maximum value considering the x = 1 then y = 7 isn't counted due to being uncolored dot.
As mentioned, Domain is the set of all x values. We check the coordinate-x plane and notice that it begins from x = -5 to x = 1. That means it is -5≤x<1
Remember that the x = 1 one is uncolored so it's either > or < but it is < because 1 has more value than -5. Now we know the domain.
About range, we check coordinate-y plane. It starts from -4 to 7. Therefore, the range is -4≤y<7.
Therefore, <em>Domain is -5≤x<1 and Range is -4≤y<7</em>
