Answer:
C I’m not sure tho
Step-by-step explanation:
D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
Her brother is 7 years old at the moment. He will be 21 when his sister is 36.
Y = mx + b
slope(m) = -5/3
(0,1/3)...x = 0 and y = 1/3
now we sub and find b, the y int
1/3 = -5/3(0) + b
1/3 = b
so ur equation is : y = -5/3x + 1/3 <== slope intercept form
or if u need it in standard form :
y = -5/3x + 1/3
5/3x + y = 1/3 ...multiply by 3
5x + 3y = 1 <== standard form
X would be 45 degrees because we know that 45+x=90 degrees. You can tell because when both angles are put together, they make a 90 degrees angle. So, we subtract 45 from 90 to get 45 due to you needing to isolate x. Thus, the answer is 45 degrees. If you can, please mark me as brainliest.
