I don't know about the first one but the second one is 34.9°. It would be that because are right angles add up to 90° and if you subract 55.1 and 90 it would equal 34.9. But this rule only works on right angles.
Answer:
56
Step-by-step explanation:
Complete question:
Z varies jointly with x and y , x=2 and y=2, z=7. Find z when x=4 and y=8 using joint variation . (I need the problem worked out step by step)
If z varies jointly with x, and y, this is expressed as;
z = kxy
If z=7 when x= 2, y= 2
7 = k(2)(2)
7 = 4k
k = 7/4
To get z when x= 4 and y = 8
z = kxy
z =7/4 (4)(8)
z = 7*8
z = 56
Hence the value of z is 56
You are taking two times a number, which is defined as x. That is equivalent to 2x. Then, you are adding three more to that product.
Answer: is C
Step-by-step explanation:
because > means open circle but it closed so its not A)
and its not D because the sign is opposite and
b and c both have the correct sign which shows which
direction the line is moving
so the answer is C because it has 4x and ends at 22 these statement are correct
Hope you understand :)
