Answer:
the slope is 3x by doing rise/run
the equation would be y=3x+5
5 is the y intercept
Answer:
y=-1/2x+7/2
Step-by-step explanation:
two lines are perpendicular if the product of the slopes is equal to -1
the slope for y=2x+4 is 2
2*x=-1
x=-1/2
the formula for the slope is
(y2-y1)/(x2-x1)=m
we know y1 and x1
(y+5)/(x+3)=-1/2
y+5=x+3/2
2y+10=x+3
2y=x-7
y=-1/2x+7/2
Notice, the third decimal place is 9 in 3.469644...
and after the 469 there's a 6, that means we can round that 469 to a 470
3.470.
Answer:
m∠2 = 118, and m∠3 = 31
Step-by-step explanation:
The 2 opposite angles of a rhombus are equal.
Angle 1 and Angle 2 are opposite to each other. Since Angle 1 is 118, angle 2 is also 118.
Now looking at the bottom triangle in the rhombus, the two sides are equal (given by 2 lines). Hence, the 2 opposite angles are equal. Since we know 3 angles of a triangle add up to 180 degrees, we can write: (let angle 3 be x):
x + x + 118 = 180
2x = 180 - 118
2x = 62
x = 62/2
x = 31
So m∠2 = 118, and m∠3 = 31
