Answer:
{}
Step-by-step explanation:
y=5-2x ............. simplication
2x+5-2x=15
5=15 so it have no real solution
Answer:
hope this helps
Step-by-step explanation:
Angle _1_and angle _4_ are vertical angle pairs.
Angle _4_ and angle _5_ are an alternate interior pair.
Angle _2_ and angle _6_ are alternate exterior pair.
Angle _1_ and angle _2_ are a linear angle pair.
Angle _2_ and angle _7_ are corresponding angle pair.
Answer; x = sqrt(39)
Explanation:
x^2 = AD x AC
And AD = 3, AC = 13
=> x^2 = 13 x 3
=> x^2 = 39
=> x = sqrt(39)
So.. hmm notice the picture below
r = h, due to similar triangles ratio, whatever "h" may be
now, we're given how much water is being poured into the cup per sec
namely dv/dt the volume's rate
so.. hmmm
