Answer:
x = -2
y = 5
Step-by-step explanation:
2x - 3y = -19 ---------------------------(I)
7x+ 7y = 21 -----------------------------(II)
Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x
(I)*7 14x - 21y = - 133
(II)* 3 <u> 21x + 21y = 63 </u> {Now add}
35x = -70
x = -70/35
x = - 2
Plug in x = - 2 in equation (I)
2*(-2) - 3y = -19
-4 - 3y = -19
-3y = -19 + 4
-3y = -15
y = -15/-3
y = 5
Answer:
-4/5
Step-by-step explanation:
3/5+(-7/5)
-4/5
Answer:
$11917.03
Step-by-step explanation:
Use Compound Interest Formula:
A = 7,000 (1 + 0.06/2)^2(9)
Simplify:
A = 7,000(1.03)^18
Solve:
A = $11917.03
Point A is situated in the 4th quadrant. To obtain point B, we have to apply symmetry and reflect point A across the y-axis. Thus, the ordinate would still be -3, but the abscissa would be +2. So, point B is (+2,-3). For point C, we have to reflect it across the x-axis. This time, the abscissa remains to be -2, while the ordinate becomes +3. So, point C is (-2,+3).
Thus, the answer is <span>B(2, −3) and C(−2, 3)</span>
