Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13
thus y = 2x +13
Answer:
The correct answer is 166.375 <em>or</em> 166.4 when rounded to the nearest tenth.
Step-by-step explanation:
If x = 0.5, then 5x^3 = 5.5^3.
5.5^3 is the same as <em>multiplying </em>5.5 by <em>itself </em> 3 times.
5.5 x 5.5 x 5.5 = 166.375 <em>or</em> 166.4 when rounded to the nearest tenth.
Hope this helps! :D
Answer:
2 Step-by-step explanation:
in the places there is X you put -3 , -3 squared minus 7 is equal to 9 , 9-7 is equal to 2
500 centimeters because one meter is 100 centimeters so I multiplied 100x5. Hope this helped have a good day
