Answer:

ED = 8

Step-by-step explanation:

AC = 21 which means AE is 1/3 of the length of AC.

So, ED must also be 1/3 of the length of BC.

1/3 x 24 = 8

Write the equation of the line in slope-intercept form that passes through the points
Bogdan [553]

Answer:

y = - 5x + 8

Step-by-step explanation:

(-8,48) and (-1,13)

m = (48-13)/(-8/- - 1) = 35/- 7

m = -5

y - 13 = - 5(x - - 1)

y - 13 = - 5(x+1)

y - 13 = -5x - 5

y = - 5x - 5 + 13

y = - 5x + 8

A triangle is such that the largest angle is 3 times the smallest angle. The third angle is 23 less than the largest angle. Find
Leokris [45]

largest angle:  3x

smallest angle:  x

third angle:  3x - 23

The sum of the angles of a triangle equals 180°

(3x) + (x) + (3x -23) = 180

7x - 23 = 180

7x = 203

x = 29

largest angle:  3x  = 3(29)  = 87

third angle:  3x - 23   = 3(29) - 23   = 87 - 23   = 64

Answer: 29°, 64°, 87°

The variables y and x have a proportional relationship, and y = 9 when x = 2.
Aloiza [94]

Answer: y=13.5


Step-by-step explanation:

1. By definition, if y=9 when x=2, then:

\frac{y}{x}=\frac{9}{2}

2. Keeping this on mind, to find the value of y when x=3, you must apply the following proccedure:

\frac{y}{3}=\frac{9}{2}

3. Now, you must solve for y, as following:

y=3(\frac{9}{2})\\y=\frac{27}{2}\\y=13.5

4. Then, the result is:

y=13.5
