<span>2-b=c    -(13-b)=c2-b=-13+b2b=15b=15/2c=2-15/2=4/2-15/2=-11/2 C cannot be negative, so 2-b not >0 and 13-b not <0
Both 2-b and 13-b cannot be both positive and negative, because 2-b=13-b is wrong
-(2-b)=c, 13-b=c,   -2+b=13-b,  2b=15, b=15/2, c=13-b=13-15/2=26/2-15/2=11/2So, finally  b=15/2 and c=11/2Answer is abs(x-15/2)=11/2

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5 ? Put your answer in slope-intercept form.
Scrat [10]

Answer:

  a.  y = 2/5x + 1/5

Step-by-step explanation:

In point-slope form, the equation of a line with slope m through point (h, k) can be written

  y = m(x -h) +k

Then a line with slope 2/5 through the point (-3, -1) will have point-slope equation ...

  y = (2/5)(x +3) -1

This can be simplified to the desired form:

  y = 2/5x +6/5 -1 . . . . . . eliminate parentheses; next, collect terms

  y = 2/5x + 1/5

Jessica Reads a story about a turtle that swam 16 feet in 24 seconds. She assumes that the time that it takes the turtle to swim
Zigmanuir [339]

Answer:

Time (secs) => distance (ft)

1 => ⅔

15 => 10

24 => 16

45 => 30

Step-by-step explanation:

Equation to represent this proportional relationship is d = tk, where,

t = time

d = distance

k = constant of proportionality

To complete the table, let's find k given that the turtles swarm 16 ft (d) in 24 secs (t).

Substitute d = 16, t = 24 into the equation.

d = tk

16 = 24k

\frac{16}{24} = k (division property of equality)

\frac{2}{3} = k

Let's complete the table by substituting the value of k and the other given value of t or d, as the case may be:

For 1 sec, let's find distance (d):

d = tk

d = 1*\frac{2}{3}

d = ⅔ ft

For 10 ft, let's find the time (t) taken:

d = tk

10 = t*\frac{2}{3}

Multiply both sides by 3

10*3 = t*\frac{2}{3}*3

30 = t*2

Divide both sides by 2

\frac{30}{2} = \frac{t*2}{2}

15 = t

t = 15 secs

For 45 secs, let's find distance (d):

d = tk

d = 45*\frac{2}{3} = 15*2

d = 30 ft
