Answer:
60
Step-by-step explanation:
x and 2x are linear pair angles.
Sum of linear pair angles is 180,
x + 2x = 180
3x = 180
x = 180 / 3
x = 60
Therefore,
the value of x is 60.
The LCD here is 12(5) = 60.
We must rewrite <span>7/12 - 2/5 with 60 as common denominator.
Doing this, we get 35/60 - 24/60 = 11/60 (answer)</span>
Answer:
The distance between A and B is 13.6
Step-by-step explanation:
Distance formula=√(x2-x1)²+(y2-y1)²
Where
x1=-7
x2=6
y1=-1
y2=-5
Putting in the formula
Distance=√(6+7)²+(-5+1)²
D=√(13)²+(-4)²
D=√169+16
D=√185
D=13.6
Answer:
x-int=-8, y-int=2,-4
Step-by-step explanation:
for the x-int
you set x to 0 then solve the equation to get -8
for the y-int
you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4
Answer:
14
Step-by-step explanation:
The perimeter is the sum of the sides, so we have
2x+x+15+4x-7=57
= 7x+8
Subtracting 8 from both sides, we get
7x= 49
Dividing 7 from both sides, we get
x=7
Our sides are then 2x=14, x+15=22, and 4x-7=21. 14 is our answer
