Answer:
x = -3
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x - y = -12 | (equation 1)
-x - y = 3 | (equation 2)
Add 1/4 × (equation 1) to equation 2:
{4 x - y = -12 | (equation 1)
0 x - (5 y)/4 = 0 | (equation 2)
Multiply equation 2 by 4/5:
{4 x - y = -12 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x - y = -12 | (equation 1)
0 x+y = 0 | (equation 2)
Add equation 2 to equation 1:
{4 x+0 y = -12 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -3 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -3
, y = 0
C is irrational because there is no definite square root for 15 whereas the square root of 36=6
For this, you have to reduce the larger fraction, which is 12/15
After reduction, it would be: 4/5 which is not equivalent to 3/4
4/5 ≠ 3/4
So, your final answer is "NO", it's not equivalent
Hope this helps!
Y = mx + b
m = (y₂ - y₁)/(x₂ - x₁)
m= (6-3)/(20-5) and m = 3/15 = 1/5. Now calculate b.
To that end plug any of the 2 pairs value, let's take (5,3)
y = (1/5).x + b
3 = (1/5).(5) + b & b= 2
The equation: (1/5)x + 2
To find the width of a rectangle when given the area and length, divide the area by the length:
Width = 59,400 / 330 = 180 feet
