Y=ax+b

Temos:

b=1

e o ponto (3,3)

Substituindo:

3a+1=3 ⇒ 3a=3-1 ⇒ 3a=2 ⇒ a=2/3

Portanto:

y=2/3x+1

Solve the equation.<br><br> 42x – 5 = 64

aliina [53]

Answer:

23/14

Step-by-step explanation:

42x - 5 = 64

Add 5 to both sides in order to isolate 42x

42x = 64 + 5

42x = 69

Divide 42 from both sides in order to isolate x

x = 69/42

The answer gives an uneven decimal so it'd be best to leave it as a simplified fraction. The simplified fraction is 23/14.

(6v^3+42v)/(2v^2+26v+84)

Kisachek [45]

Answer:
_______________________________________________
The simplied version is:
_______________________________________________
" $\frac{3v(v^2+7)}{(v^2+13v+42)}$ " ;

or; write as: " $\frac{3v(v^2+7)}{(v+7)(v+6)}$ " .
_______________________________________________
Explanation:
_______________________________________________
Given:
_______________________________________________
" $\frac{6v^3 +42 v}{2v^2 +26v + 84}$ " ;
_______________________________________________
→ Factor out a "6v" $\frac{6v(v^2+7)}{2(v^2+13v+42)}$ in the "numerator"; & factor out a "2" in the denominator; as follows:
____________________________________
→ $\frac{6v(v^2+7)}{2(v^2+13v+42)}$ ;
____________________________________
→ " $\frac{3v(v^2+7)}{(v^2+13v+42)}$ " ;
______________________________________________

or; factor out the "denominator" :
______________________________________________
→ (v² + 13v + 42) = (v+7)(v+6) ;
______________________________________________
and write as:
______________________________________________
→ " $\frac{3v(v^2+7)}{(v+7)(v+6)}$ " .
______________________________________________

Nancy and Karen went on a trip to the mountain. Nancy started her trip 30 minutes later than Karen. They started from the same p

Katyanochek1 [597]

Distance = (rate)(time)
In this problem, note that both girls traveled the same distance.

Karens distance = r * 1.5 hrs we dont know her rate
Nancy distance = 50 * 1 hr we know she started 30 min later
but arrived at the same time

since the distances are equal
r*1.5 = 50 * 1 all you have to do is solve for r

1.5r = 50
r = 50/1.5
r = 33 1/3 miles per hour
