6 0
Answer:

Explanation:

(3/14)k - 1 - 4 - (2/7)k = 0
(3/14)k - (4/14)k - 5 = 0
(-1/14)k = 5
-k = 5 x 14
k = -70

Can you write this equation in point-slope form?<br><br> y = ½x + 4?
Svet_ta [14]
Yes.  This equation given:
______________________________
   " y = (½)x + 4 " ;  in point-slope form; also known as: "slope-intercept form" ; is:
______________________________________
    " y = (½)x + 4 " .
______________________________________
In other words, the equation given is ALREADY written in "point-slope form" ; or, "slope-intercept form".
______________________________________
Note:   An equation that is written in "point-slope form"
             (or, "slope-intercept form"), is written in the format of:
______________________________________
" y = mx + b " ;_________________
in which:_________________
"y" is a single, "stand-alone" variable on the "left-hand side of the equation"; "m" is the coefficient of "x"; also:
"m" is the slope of the line; which is what we want to solve for;
"b" is the "y-intercept"; or more precisely, the value of "x"
(that is; the "x-coordinate") of the point at which "y = 0";
that is, the value of "x" ; or the "x-coordinate" of the point at which
the graph of the equation crosses the "x-axis".
______________________________________
Note that in our given equation, which is written in "point-slope form" (or, "slope-intercept form" — that is:  " y = mx + b "  ;
_______________________________________
which is:  " y = (½)x + 4 " ;
_______________________________________
we have:
_______________________________________
  "y" isolated as "stand-alone" variable on the "left-hand side" of the equation;

  m = ½ ;
  b =  4 .

Of the songs in Brianna's music library, 1/3 are rock songs. Of the rock songs, 7/10 feature a guitar solo. What fraction of the
Marat540 [252]

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

is 1×7 on top, and

3×10 on the bottom.

= (1×7)/(3×10)

= 7/30

7/30 cannot be simplified, so that is the answer.

What is 34,569,072 rounded to the nearest million
strojnjashka [21]
For this, look at the 6th digit (hundred-thousands). If that digit is more than or equal to 5, then the next digit is rounded up. Since it is, the answer becomes 35,000,000.
Answer: 35,000,000

Find the midpoint of the line segment joining the points (5,6) and (-1,-6).
kumpel [21]

Answer:

The midpoint is (2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(5+-1)/2 =4/2 =2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(6+-6)/2 =0/2 =0

The midpoint is (2,0)
