Answer:
17. x = y^2 - 2ay +a^2
18. x = y^2 - a
Step-by-step explanation:
17. Since we want to make x the subject of the formula, we first isolate the square root of x and get
= y - a.
squaring both sides,
x = y^2 - 2ay +a^2
18. Since both x and the a are under the square root, we first start by squaring both sides.
So y^2 = x+a.
Isolating the x, we get
x = y^2 - a
Answer:
7/8
Step-by-step explanation:
7/8 because he completed 4/8 (half) before he finished dinner. 4+2=6. So/ it should be 7/8.
9m = 4.5
divide by 9 for 9m and 4.5
9m/9= 4.5/9
m= 0.5
3v= -105
divide by 3 for 3v and -105
3v/3=- 105/3
v= -35
17m = 85
divide by 17 for 17m and 85
17m/17= 85/17
m= 5
Answers: 0.5,-35 and 5
Answer:
M<2 =61* M< = 61
Step-by-step explanation:
You know angle 4 is 119* and the straight line is 180* so if u do 180 - 119 it is 61 , therefore 1 ,2,and 3 are 61*
