Answer:

Step-by-step explanation:

To solve this equation, group like terms together:  'w' terms on the right and constants on the left:

-10 = 7w.  Then:

w = -10/7 (exact) or w ≈ 1.43

Dani’s Neighbours paid her to take care of their bird during their vacation Danny spent four dollars of her earnings on an after
Allushta [10]

Answer:

Inequality that represents the amount paid by neighbors of Dani will be

x ≤ 8 + (4 + 16)

Step-by-step explanation:

Let the neighbors of Dani paid her to take care of their bird = $x

Danny spent on an afternoon snack = $4

She paid the amount for a new book = $16

Now the amount left with her is at least $8.

Therefore, inequality which represents the amount paid by her neighbor will be

x - 4 - 16 ≤ 8

x ≤ 8 + (4 + 16)

Are (2,9) and (-3,-6) both on the line y = 4x + 6? If not, find an equation for the line that does pass through both points.
igor_vitrenko [27]

Answer:

no, y=3x+3

Step-by-step explanation:

plug both points into the equations:

  • 9=4*2 +6 -> 9=8+6, doesn't work
  • -6=4(-3)+6 -> -6=-6, works

one works but the other doesn't so now we find a line through both points

use the formula (y_2-y_1)/(x_2-x_1) to find the slope:

  • (-6-9)/(-3-2)=-15/-5=3

y=3x+b, plug in a point to find b:

  • 9=3(2)+b
  • 9=6+b
  • b=3
  • y=3x+3

2 triangles measure 55 and 20 what is the measure of the third angle
OleMash [197]

Answer:

x = 105

Step-by-step explanation:

The angles of a triangle add to 180 degrees

Let x be the third angle

55+20 +x =180

75 +x = 180

x = 180-75

x = 105
