There is a line that includes the point 7,2 and has a slope of -1/3
Solnce55 [7]

Answer:

y= -1/3x + 13/3

Step-by-step explanation:

we can find the equation of the line thanks to this formula

y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the point, while m indicates the slope

y-2 = -1/3(x-7)

y = -1/3x+7/3+2

y= -1/3x + (7+6)/3

y = -1/3x+13/3

Suppose you have $100 in a savings account earning 2 percent interest a year. After five years, would you have more than $102, e
pentagon [3]
You would have more than $102.

Earning 2% a year in interest would get you $2 in interest the very first year:

100(0.02) = 2

Adding this to the amount in the account, you would have 100+2 = 102 after the first year.

Given<br> mZABD is a straight angle.<br> m<br> ABC = 2x + 50°<br> mZCBD = 6x + 2°<br> Find mZCBD:
Sliva [168]

Answer:

m\angle CBD=98°

Step-by-step explanation:

Given:

m\angle ABD is a straight angle.

m\angle ABC=2x+50°

m\angle CBD=6x+2°

∵ m\angle ABD is a straight angle.

∴ m\angle ABD is equal to 180°.

Now, angle ABD is a sum of angles ABC and CBD. This gives,

\angle ABD=\angle ABC+\angle CBD\\180=2x+50+6x+2\\180=8x+52\\8x=180-52\\8x=128\\x=\frac{128}{8}=16

∴ x=16.

Now, m\angle CBD=6x+2

Plug in 16 for x and calculate angle CBD. This gives,

m\angle CBD=6x+2=6(16)+2=96+2=98°.

Therefore, m\angle CBD=98°.
