Answer:
4
Step-by-step explanation:
The y-variable can be eliminated by adding 3 times the first equation to the second:
3(2x -y) +(x +3y) = 3(11) +(-5)
7x = 28 . . . . simplify
x = 4 . . . . . . . divide by 7
_____
Using Cramer's Rule, you can also find the x-value. The math is not so different.
x = ((-1)(-5) -(3)(11))/(-1(1) -3(2)) = -28/-7 = 4
Answer: Choice B. 54degrees
Step-by-step explanation:
Angles 1 4 5 8 are equal and angles 2 3 6 7 are also equal. These two sets of angles of supplementary(you‘d get 180 by adding them).
so
13x+9=180-(5x+9)
by simplifying the equation youll get
18x+18=180
x=9
so angle 7(and therefore angle 6) equals
5*9+9=54
Answer:
the number that goes in the blank is 8
Step-by-step explanation:
The question illustrates a linear equation, and the equation that represents the greatest horizontal height is H = 2V + 3
<h3>How to determine the equation?</h3>
From the complete question, we have the following highlights:
The greatest horizontal height is three more than twice the greatest vertical length.
This means that:
H = 2 * V + 3
Evaluate the product
H = 2V + 3
Hence, the equation that represents the greatest horizontal height is H = 2V + 3
