Answer:

y = - $\frac{1}{4}$ x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - $\frac{1}{4}$ , hence

y = - $\frac{1}{4}$ x + c ← is the partial equation

To find c substitute (12, 2) into the partial equation

2 = - 3 + c ⇒ c = 2 + 3 = 5

y = - $\frac{1}{4}$ x + 5 ← equation of line

answer :

y=-1/4x+5

my work:

y=mx+b

2=-1/4(12)+b

2=-3+b

+3 +3

5=b

y=-1/4x+5

During a field trip, 60 students are put into equal-sized groups. Describe two ways to interpret 60 ÷ 5 in this problem *

sergeinik [125]

Answer:

$x=12 groups$

This will give 5 Students each in 12 different equally sized groups

$x'=5groups$

This also shows that students can grouped in equal groups of 12 in 5 places

Step-by-step explanation:

From the question we are told that

60 children in equal sized groups

Generally interpreting $60\div 5$ can be mathematically represented as

$x=\frac{60}{5}$

$x=12 groups$

This will give 5 Students each in 12 different equally sized groups

$x'=\frac{60}{12}$

$x'=5groups$

This also shows that students can grouped in equal groups of 12 in 5 places

Find the measure of the exterior angle.

miss Akunina [59]

Answer:

120 degrees! (line) or 300.

Step-by-step explanation:

All lines are 180 degrees, this triangle is congruent, so all sides are 60 degrees. 180 minus 60 is 120.

If it's a measure of a 360 degree angle, using 2 lines from the triangle, then you take 60 away from 360. A circle formed with that angle at it's radius would be 300 degrees.
