The sum of the measures of angle 4,7, and _____ is equal to 180

1 answer:

6 0

7 I think because if you would put a zero behind the 4 and 7 and add them together it will be 110 and all that's left if u subtract them from 180 is 70 (7)

Equation is:

$y = \frac{x}{9}$

=> $y = (\frac{1}{9} ) x$

Comparing it with $y = kx$ , where k is the proportionality constant, We get:

What are the coordinates of one of the vertices of a rectangle when two sides are given by the lines x - 3y = -8 and 3x + y = 6?

Aleonysh [2.5K]

Answer:

(1, 3)

Step-by-step explanation:

x - 3y = -8

3x + y = 6

Isolate a variable in one of the equations:

y = 6 - 3x

Substitute the value of y into the other equation:

x - 3(6 - 3x) = -8

Use distributive property:

x - 18 + 9x = -8

Combine like terms:

10x - 18 = -8

Isolate the variable:

10x = 10

x = 1

Substitute the value of x into any equation:

3(1) + y = 6

3 + y = 6

Isolate the variable:

y = 3

Answer:1.2 m/s

Step-by-step explanation:

Total distance covered is 500+500+200 m so the average velocity is given by

V = distance/time

V=1200/(17*60)

V=1.176 m/sec
