Consider the given equations:
(Equation 1)
(Equation 2)
(Equation 3)
Adding equations 1 and 3, we get
So, we get (Equation 4)
Multiplying equation 3 by '6', we get
(Equation 5)
Subtracting equation 5 from equation 2, we get
(Equation 6)
Multiplying equation 4 by '21' and adding it to equation 6, we get
So, z = -5
Since,
So, y=-5
Now,
So, x = -4
Therefore, x = -4, y= -5 and z= -5 are the solutions to the given equations.
Answer:
The slope is -3/4
Step-by-step explanation:
3x+4y = 8
We want to get the equation in slope intercept form
y = mx+b where m is the slope
Subtract 3x from each side
3x+4y-3x= -3x+8
4y = -3x+8
Divide by 4
4y/4 = -3x/4 +8/4
y = -3/4x +2
The slope is -3/4 and the y intercept is 2
Answer:
tan(C) = √3/√2
Step-by-step explanation:
First, using Pythagorean Theorem, find AC.
=> AC = √(3√5)² - (3√3)²
=> AC = √45 - 27
=> AC = √18
=> AC = 3√2
tan C = 3√3/3√2
= √3/√2
Answer:
0.0167
Step-by-step explanation:
There are 5 "Sig Figs" in this number: 1, 6, 6, 6, and 7
0.01666 rounded to <em>three</em> significant figures is .0167.
There is 7,000 female students, and 5,000 male students. Because, if there was 2,000 more female students then male, you have to find out what two numbers add up to 12,000. (Tip, to make it easier, take away the thousands, like 7+5)
