Find the solution of this system of equations -4y = -64 - 6x 4x - 4y = -36

Mathematics

blagie [28]3 years ago
4 0

The solution of system is x=14, y=37

Step-by-step explanation:

Given equations are:

-4y = -64 - 6x  => 6x-4y=-64     Eqn 1

4x - 4y = -36     Eqn 2

Subtracting equation 2 from eqn 1

(6x-4y)-(4x - 4y) = -36+64\\6x-4y-4x+4y=28\\2x=28\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{28}{2}\\x=14\\Putting\ x=14\ in\ equation\ 1\\-4y=-64-6(14)\\-4y=-64-84\\-4y=-148\\Dividing\ both\ sides\ by\ -4\\\frac{-4y}{-4}=\frac{-148}{-4}\\y=37

The solution of system is x=14, y=37

Sally is training for a marathon. She goes for a run every Tuesday and
nikdorinn [45]

Speed = distance / time

Tuesday: speed = 2.4km / 18 minutes = 0.13 km per minute

Friday: speed = 1.8 km / 12 minutes = 0.15 km per minute

0.15 is larger than 0.13 so she ran faster on Friday.

Lines y and z are parallel.
Mrac [35]

Answer:

28 degrees

Step-by-step explanation:

step 1

Find the measure of angle 1

m\angle 1+65^o=180^o ----> by supplementary angles

m\angle 1=180^o-65^o=115^o

step 2

Find the value of x

(10x+5)^o=m\angle 1 ----> by corresponding angles

substitute

(10x+5)^o=115^o

10x=110\\x=11

step 3

Find the measure of angle 2

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

m\angle 1+m\angle 2+(4x-7)^o=180^o

substitute

115^o+m\angle 2+(4(11)-7)^o=180^o

m\angle 2=180^o-152^o=28^o
