Indicate in standard form the equation of the line passing through the given point and having the given slope. R(4, 0), m = 5

1 answer:

7 0

Hello,

If R(4,0) is the given point and m=5 the slope,

y-0=5(x-4)==>y=5x-20 is the reduced form
and 5x-y-20=0 is the standard form

Explanation:

1) sin(37º)=x/10.3————>trigonometric ratio (sine)

2)7²+10²=c²—————-> pythagorean theorem

3) using sine—————> sin(51º)=9/x

using tangent —————> tan(51º)=9/x and x = 7.3 (rounded)

4)using pythagorean theorem————> 6²+7²=c²

angle b is tanx=6/7 where x = 40.6 degrees, angle a is tanx=7/6 where x = 49.4

Answers:

1)x= 6.2

2)x= 12.2

3)x= 11.6 (rounded)

4)x= 9.2

Formula used: 40+x = 4x-3 x is used for ET

Step-by-step explanation:

40+x = 4x-3

+3 +3

43+x = 4x

-x -x

43 = 3x

3 3

14.3 = x

then substitude this on 5x+3 on WT and you arr good

algol [13]

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

$d_t=2d$

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

$Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days$

Now, we multiply the distance per day by the total number of days:

$Distance, D=2d\times 16\\\\=32d$

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
