Answer:
Step-by-step explanation:
<u>Given system:</u>
- 2x - y = - 2
- 15x - 2y = - 7
<u>Solve by elimination, multiply the first equation by - 2 and add up the equations:</u>
- -2(2x - y) + 15x - 2y = - 2(- 2) - 7
- -4x + 2y + 15x - 2y = 4 - 7
- 11x = - 3
- x = - 3/11
<u>Find the value of y:</u>
- 2( - 3/11) - y = - 2
- -6/11 - y = - 2
- y = 2 - 6/11
- y = 1/11
<u>Solution is:</u>
- <em>None of the answer choices is matching this solution. Something must be wrong with the given equations.</em>
Answer:
x = 15
Step-by-step explanation:
=> x - 3 = 12
=> x = 15
Answer:
(y-(-2))/(x-(-1)= (-2-4)/(-1-3)
(y+2)/(x+1)= (-6)/(-4)
(y+2)/(x+1)= (3/2)
Cross multiplying
2y+4= 3x+3
3x-2y-1=0
Answer:
AB¯¯¯¯¯ is reflected across the y- axis to form A′B′¯¯¯¯¯¯¯ .
Answer:
Step-by-step explanation:
Formula
V pi * r^2 * h
Givens
r = 3 m
h = 6 m
pi = 3.14 when used.
Solution
V = pi r^2 * h
V = pi * 3^2 * 6
V = 9 * 6 * pi
V = 54 * pi Volume in terms of pi
V = 54*3.14 Volume using a value for pi
V = 169.56 to the hundred's place.
