When p= 12, t= 2, and s= 5, r= 18. If rvaries directly with p and inversely with the product of sand t, what is the
constant of variation?
Answers
Answer:
15
Brainliest, please!
Step-by-step explanation:
r = kp/(st)
p = 12, t = 2, s = 5, r = 18
18 = k(12)/(2)(5)
18 = 12k/10
12k = 180
k = 15

−5x+4y=3
x=2y−15
what would be the values of x and y
Answers
Answer:
x=9 y=12
Step-by-step explanation:
eqn 1 - x=2y-15
eqn 2- -5x+4y=3
-5(2y-15)+4y=3
-10y+75+4y-3=0
-6y+72=0
y= 12
x=2y-15
x=2(12)-15
x= 9
Substitution,
-5(2y-15) + 4y=3
-10y + 75+ 4y=3
75-3 = 10y - 4y
6y = 72
y. = 72/6
Y= 12
Now find x
X= 2(12) - 15
X= 24 - 15
X= 9
Soo
X= 9; Y= 12

This is very urgent and I need to get it done soon, whoever is willing to help me I'll mark you as brainliest. Thank you!
Answers
Answer:
The united nations flag the translation can be any of the blue triangles and the reflection if the flag itself as it is symmetrical
Step-by-step explanation:
The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
If you're reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you're reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
Therefore, The united nations flag the translation can be any of blue triangles and the reflection if the flag itself as it is symmetrical.

(21 + 3y) + y = 90
21 + 4y = 90
4y = 69
y = 17.25
x = 21 + 3(17.25)
x = 21 + 51.75
x = 72.75
Answer check:
72.75 + 17.25 = 90
90 = 90 Corrrrrrect !
Explanation:
x = 3y + 21
And x + y = 90° (complementary angle)
Substitute x value in the equation:
3y + 21 + y = 90
4y + 21 = 90
4y = 69
y = 69/4
y = 17.25
x = 3(17.25) + 21
x = 51.75 + 21
x = 72.75
