Answer:
x=3,y=-3
Step-by-step explanation:
Isolate x for 4x +y=9: x=9-y/4
Substitute x = 9-y/4
[5 x 9-y/4+2y =9]
Isolate y for (45+3y/4)=9:
y=-3
For x= 9-y/4
Substitute y = -3
x= 9-(-3)/4
9-(-3)/4=3
X=3
The solutions to the system of equations are:
x=3 y= -3
(1.5×10^7)⋅30,000⋅(6.7×10^5) = 3.015x10^18
32.8329103188 is the square root
Perimeter is 48
12+8+4+4+4+4+4+8=48
Answer:
Step-by-step explanation:
<u>Given formula:</u>
- 4y= -kx - 2, where slope is 4
<u>Slope-intercept formula is:</u>
- y = mx + b, where m is the slope
<u>Finding slope by bringing the formula to the same format as above:</u>
- 4y = -kx - 2
- y = -k/4x - 1/2
<u>Slope is -k/4 and comparing it with the given:</u>
