Answer:
The constant of proportionality k = 12
Hence, option A is true.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get
y ∝ x
y = kx
Where 'k' is called the constant of proportionality.
In our case,
The given equation is
y = 12x
comparing with the equation y = kx, we can say
k = 12 which is the constant of proportionality.
Therefore, we conclude that:
The constant of proportionality k = 12
Hence, option A is true.

Answer: does someone have it cause I’m stuck to
Step-by-step explanation:
Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?
Answer:
Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.
Step-by-step explanation:
18 ÷ 10 = 1.8 (Lisa's rate)
14 ÷ 8 = 1.75 (Marie's rate)
1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)
1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)
1.5(x+4)-3=4.5(x-2)?

I’ll GIVE YOU BRAINLYIEST1. A triangle has coordinates at X(3, 7), Y(6, 7) , and Z(4, 2) . Dixie created transformed the triangle so that the new coordinates were X(- 3, - 7) , Y^ prime (-6,-7) and Z^ prime (-4,-2) . Which rule best describes this transformation?
A. (x, y)—>(x, -y)
B. (x, y)—>(-x, -y)
C. (x, y)—>(-x, y)
D. (x, y)—>(x - 6, y - 2)
Answer:
B. (x, y) → (-x,-y)
This rule is given triangle is reflection about origin or
Rotation clockwise or counter clock wise with 180°
Step-by-step explanation:
Explanation:-
A triangle has coordinates at X(3,7),Y(6,7) and Z(4,2)
The Rule ( x, y)→ ( - x, -y)
This rule is given triangle is reflection about origin or Rotation clockwise or counter clock wise with 180°
X( 3,7) → X¹ ( -3,-7)
Y(6,7) → Y¹ (-6,-7)
Z(4,2) → Z¹( -4 ,-2)
The perimeter of the triangle is 30 cm
The perimeter of the rectangle is also 30 cm.

Answer:
B. Not enough information.
Step-by-step explanation:
We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.
AAA is not a criterion that proves two triangles are congruent.
Therefore, we will conclude that there is not enough information.

Answer:
95.2
Step-by-step explanation:
Answer:
95.2
Step-by-step explanation:
476÷5=95.2
[tex]\sqrt[5]{476} }[/tex]
9x5=45
47-45=2
bring down the 6
26
5x5=25
26-25=1
Since the one is excess the answer is 95 and 1/5
but 1 divided by 5 equals .2
so the answer would b 95.2
