The angles are vertically opposite,
therefore,
9x + 22 + 130 = 180
9x + 152 = 180
9x = 180 - 152
9x = 28
Answer:
The two lines intersect (in other words, they have a common meeting points)
Step-by-step explanation:
Thinking process:
A linear equation takes the form of
where , m = gradient
c = y-intercept (point where the line cuts the y-axis)\
Suppose we have these two linear equations:
We can find the point of intersection by solving the two equations simultaneously like this:
sub y = 2x + 4 into equation (2) gives:
2(2x+4) = -6x -1
solving yields - 0.9
Substituting x= -0.9 into equation 1 yields:
y = 2.2
In terms of the Cartesian coordinates (x, y) the point of intersection will be (-0.9, 2.2)
Hence, the point of intersection is a solution of two linear equations.
Answer:
$319.60
Step-by-step explanation:
Normal Game console cost : $399.50
Discount: %20 (0.20)
$399.50×0.20= $79.90
Total cost of discount $79.90
$399.50-$79.90= $319.60
New cost after Discount= $319.60
4= 21, 2=21, 4=159 hope this helps
Answer:
s = -15
Step-by-step explanation:
-12 + (-18) = -30
-30= 2s
-15 = s
