Which line has a slope of -5/8 and goes through the point (2,-3)
1 answer:
Answer: y = -5x/3 - 7/4
Step-by-step explanation:
The equation of a line in slope and point form is given as
y - = m(x -
)
where m is the slope
= 2
= -3
m = -5/8
Substituting into the formula , we have
y - ( -3 ) = -5/8 ( x - 2 )
y + 3 = -5x/8 + 5/4
This could also be written in slope - intercept form , that means we will make y the subject of the formula
y = -5x/8 + 5/4 - 3
y = -5x/3 - 7/4

Answer:
x=12.124
Step-by-step explanation:
here 7 and x are the legs of the triangle where as 14 is hypotenuse because it is opposite opposite to 90 degree.
using pythagoras theorem
a^2 + b^2 = c^2
here and b are legs and c is hypotenuse
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 =196-49
x^2 =147
x=
x=12.1243
x=12.124 (after converting to the nearest hundredth)
