Answer:

x=-4 and x=-6

Step-by-step explanation:

-5(5x+4)=80\\-25x-20=80\\-25x=100\\x=-4

2(-5x+3)=66\\-10x+6=66\\-10x=60\\x=-6

just distribute, isolate your x, and divide by whichever number is attached to x

- sqrt737 is rational or irrational
denpristay [2]

Answer: <u>Irrational </u>

It's irrational because of how 37 comes out of the square root.

For example:

The square root of 64 comes out to 8, which is a whole number. But 37, comes out as an integer and a decimal.

Three vectors A, B, C in three-dimensional space satisfy the following properties
wlad13 [49]

Answer:

\frac{7}{8}\pi

Step-by-step explanation:

observe

||a–b+c|| = ||a+b+c||

(a-b+c)² = (a+b+c)²

(a+b+c)² – (a-b+c)² = 0

((a+b+c)+(a-b+c))((a+b+c)–(a-b+c)) = 0

(2a+2c)(2b) = 0

(a+c)b = 0

a•b + c•b = 0

||a||×||b||×cos(π/8) + ||c||×||b||×cos(θ) = 0

\cos(\theta)=-\frac{||a||\times ||b|| \times \cos(\frac{\pi}{8})}{||c||\times ||b||}=-\cos(\frac{\pi}{8})\\ \theta=\frac{7}{8}\pi

Please help !Suppose that the height in centimeters of a candle is a linear function of them out of time in hours it has been bu
Elan Coil [88]

Answer:

  17.8 cm

Step-by-step explanation:

In the 17 hours between heights of 18.6 cm and 15.2 cm, the candle lost 3.4 cm in height. That is, the height decreased at the rate of ...

  (-3.4 cm)/(17 h) = -0.2 cm/h

In the 4 hours between 12 hours and 16 hours of burning time, the candle will have changed its height by (4 h)(-0.2 cm/h) = -0.8 cm.

The height at 16 hours of burning is then 18.6 cm -0.8 cm = 17.8 cm.
