Use the given conditions to write an equation for the line in point-slope form and slope-intercept form.
ehidna [41]

Answer:

  • y +5 = -5(x +6)
  • y = -5x -35

Step-by-step explanation:

For a line with slope m through point (h, k), the point-slope form of the equation is ...

  y -k = m(x -h)

For your point and slope, the line is ...

  y +5 = -5(x +6)

__

Adding -5 and simplifying puts this in slope-intercept form.

  y = -5x -30 -5

  y = -5x -35

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
Ksivusya [100]

Answer:

The answer would be A. -4

Step-by-step explanation:

If you right it out like x-6=5(x+2), then you distribute the 5, you get: x-6=5x+10. Then subtract x from both sides, you get: -6=4x+10. Subtract 10 from both sides, you get: -16=4x. The all you have to do is divide both sides by 4, and you get: -4=x

7. Find: (i) x + y +z (ii) a+b+c+d​
pochemuha

Answer:

Q.1 360° Q.2 360°

Step-by-step explanation:

Q.1 let the third angle of the triangle be a

70°+40°+a=180(by angle sum property)

110°+a=180

a=180°-110°

a=70°

angle x=70°+x=180°(linear angle)

x=180°-70°

x=110°

angle z= 40°+z=180

z= 180°-40°

z=140°

angle y=a+y=180°

70°+y=+80°

y=180°-70°

y=110°

y+z+x=110° +110° +140°=360

Q.2 let the fourth angle of the quadrilateral be x

120°+70°+60°+ x=360° (by angle sum property)

250°+x=360°

x=360°-250°

x=110°

angle a=120°+a=180°(by linear angle)

a=180°-120°

a=60°

angle b=70°+b=180°

b=180°-70°

b=110°

angle c=x+c=180°

110° + c=180°

c=180°-110°

c=70°

angle d=60°+d=180°

d= 180° -60°

d=120°

a+b+ c+d=120°+110°+60°+70°=360°
