Answer:
114 degrees
Step-by-step explanation:
6x+12=3x+63
-3x -12 -3x -12
3x=51
x=17
6(17) +12 = 114
Answer:
eight divided h 8 '/. h
Step-by-step explanation:
Hi there,
Let's get started,
The line is parallel to the line whose equation is y = 4x + 1.
So the slope will be the same.
The equation that would be possible is :
y = 4x + c
By the way, we know that the line passes through (-3 ; 2).
We just have to substitute these values in the equation in order to find the value of c.
(x ; y) ==> x = -3 and y = 2
Let's do this then,
2 = 4(-3) + c
c = 2 - 4(-3)
c = 2 + 12
c = 14
In short, the answer would be :
y = 4x + 14.
Hope this helps !

Areas are measured in km2, not in km.
1. y - y1 = m(x - x1)
slope(m) = -1/3
(3,6)...x1 = 3 and y1 = 6
now we sub
y - 6 = -1/3(x - 3) <==
2. y - 9 = -(x + 2)
y - 9 = -x - 2
y = -x - 2 + 9
y = -x + 7 <===
3. y - y1 = m(x - x1)
slope(m) = 0....horizontal lines have 0 slopes
(-4,-1)...x1 = -4 and y1 = -1
now we sub
y - (-1) = 0(x - (-4)
y + 1 = 0(x + 4) <===
4. x + 3y = 6
3y = -x + 6
y = -1/3x + 2.....slope here is -1/3. A parallel line will have the same slope
y = mx + b
slope(m) = -1/3
(5,3)...x = 5 and y = 3
now we sub and find b, the y int
3 = -1/3(5) + b
3 = -5/3 + b
3 + 5/3 = b
9/3 + 5/3 = b
14/3 = b
ur equation is : y = -1/3x + 14/3
5. Perpendicular lines have negative reciprocal slopes. For example : the slope of one line will be 3 and the slope of the other line would be -1/3.
(-1,-4) / (3,3)
slope = (3 - (-4) / (3 - (-1) = (3 + 4) / (3 + 1) = 7/4
that means our other line has to have slope of -4/7, the negative reciprocal
(-3,3)(4,-1)
slope = (-1 - 3) / (4 - (-3) = -4/7
so ur answer is (4,-1)
