K(x) = 6x + 100 k(-5) = 1

Mathematics

to find k(-5) we need to substitute -5 for every x in k (x) and calculate the result:

k(x)=6x+100 becomes:

k(-5)=(6*-5)+100

k(-5)=-30+100

k(-5)=70

plz mark me as brainliest :)

Half a number plus 5 is 11.What is the number?​
SOVA2 [1]
<h3>Solution :</h3>

<u>Let x be the number</u>

\small\bold\red{→}\small\bold{(\frac{1}{2} )x + 5 = 11}

\small\bold\red{→}\small\bold{(\frac{1}{2})x + 5 - 5 = 11 - 5}

\small\bold\red{→}\small\bold{(\frac{1}{2})x = 6}

\small\bold\red{→}\small\bold{2 × (\frac{1}{2})x = 6 × 2 }

\small\bold\red{→}\small\bold{x = 12}

Answer:

Graph # 3

Step-by-step explanation:

-2x + 5y > 15               Let x  = 0  solve for y

 -2(0) + 5y = 15             change the > to an =

     5y = 15

      y =3     Point (0, 5) is on the graph

 Graph # 3 is correct because the y-intercept  is 5  

    x          y

    0          3                    -2(0) + 5y = 15;     5y = 15

    5          5                  -2(5) + 5y = 15;    -10 + 5y = 15;  5y = 25; y = 5

    10         7                   -2(10) + 5y = 15; -20 + 5y = 15; 5y = 35; y = 7

   The graph > the line is dotted and you will shade above the line

Find the measure of the central angle that you would draw to represent 67% in a circle graph. Round your answer to the nearest d
natima [27]
Circle=360 so
67%=67% of 360

percent means parts out of 100 so
67%=67/100=0.67

'of' means multiply
67% of 360=0.67 times 360=241.2

round
241

answer is 241 degrees
