Answer:
C. 1
Step-by-step explanation:
f(2) simply means x = 2.
We are trying to find the y-value when x = 2.
According to the graph, when x = 2, y = 1.
Therefore, f(2) = 1.
3. Mr. Matho has a garden in the shape of an equilateral triangle, He has planted a tree in each corner
of his garden; an oak tree, a maple tree, and a pine tree. In order to water his garden, he decides
that the best place to put a sprinkler would be in the middle of the garden, so it would be equidistant
from all three trees. If the perimeter of his garden is 36 m and the sprinkler is 2-3 m from the
fence joining the oak and maple tree, how far away is the sprinkler from any one of the trees?
Answer:
The distance the sprinkler is away from any one tree is 6.32 m if it is 2 m from the fence and 6.71 m if it is 3 m from the fence.
Step-by-step explanation:
Since the perimeter of the triangle P = a + b + c where a, b and c are the length of sides. Since the triangle is an equilateral triangle, a = b = c. So,
P = 3a
a = P/3
Since the perimeter = 36 m,
a = 36 m/3 = 12 m.
Since the sprinkler is 2 m from the fence joining the oak tree and maple tree, thee line perpendicular from the sprinkler to the fence is thus 2 m. This line cuts the side at the midpoint of the fence which is 12 m/2 = 6 m.
Since this is now a right-angled triangle, we now use Pythagoras' theorem to find the distance from the sprinkler to each tree which is
L = √[(2 m)² + (6 m)²]
= √[ 4 m² + 36 m²}
= √40 m²
= 2√10 m
= 6.32 m
If the fence is 3 m from the sprinkler, the distance
L = √[(3 m)² + (6 m)²]
= √[ 9 m² + 36 m²}
= √45 m²
= 3√5 m
= 6.71 m
So, the distance the sprinkler is away from any one tree is 6.32 m if it is 2 m from the fence and 6.71 m if it is 3 m from the fence.

Answer:
$125
Step-by-step explanation:
To solve for one ticket divide 75 by 3 to get 25. Then to solve for 5 multiply 5 x 25 to get 125. So 5 tickets cost $125.
Hope that helps and have a great day!
Answer:
$125
Step-by-step explanation:
75 divided by 3 = 25
this means that the cost of one ticket is $25
so now all we need to is multiply $25 by 5 = $125

It’s for algebra class please help my teacher is really strict but okay please thank u a lot
Answer:
The equation is true/ or an identity
Step-by-step explanation:
Plug in 7 for x, you get
2(7)+3=17
14+3=17
17=17
Answer:
14+3=17or(2*7) +3=17basically 17=17Step-by-step explanation:
2x+3=17 and x =7
Let's Substitute:(Because the variable is x and we have a value for it which is 7)(Bold and underlined is where the variable is in the equation)Since x is equal to 7 we are going to substitute it in the equation.
So: (2*7) +3=1714+3=17I think this is the answer since already having the value of x is an answer please let me know if I am wrong or answered incorrectly so I can change my answer or let everyone know its wrong so it can be deleted. I only want to spread truthful information and assistance so let me know how I did by rating the answer, saying thanks or reporting it so I can improve.

points (6, -1) and (1,8)?
Answer:
-1.8
Step-by-step explanation:
m= y2 - y2over x2 - x1
m= -1 - 8 over 1 - 6 = -1.8
m= -1.8
