Answer:
4x+3y+3=0
Step-by-step explanation:
Equation of a line containing a point (x1,y1),
and a slope m is given by,
(y-y1)=m(x-x1)
Here, x1= -3 , y1= 3 , m= -4/3
Putting the values,
(y-3)=-4/3(x+3)
or,3(y-3)=-4(x+3)
or,3y-9=-4x-12
or,4x+3y+3=0 , is the required equation.
Answer:
negative StartFraction 2 Over 5 EndFraction
Step-by-step explanation:
2x +5y = 10
5y = - 2x + 10
y = - 2/5 x + 10
Equating it with y = mx + b
m = - 2/5
For 27 since all they did was add a zero on the end of the first number (9,554), you just add that zero to the end of you quotient to make 95,540 / 562 = 170
For 28 the answer is 110.59 (rounded to nearest hundredth) because you take the distance between the moon and earth and divide it by the width of the moon 384,400 / 3,476 = 110.58688
Hope this helps!
Answer:
x = -8°
Step-by-step explanation:
Angle 2
Since the triangle is isosceles, Angle 2 is the same as the missing angle
So angle 2 would be:
180 - 34 = 2(angle 2)
So 146 = 2(x + 81)
146 = 2x + 162
146 - 2x = 162
-2x = 16
x = -8
Check
146 = 2(-8+81)
146 = 2(73)
146 = 146
Correct!
