Answer:
B. (-2,-4)
Explanation
Given equations:
y = 3x + 2
y = -2x - 8
Solving both equations will yield the values of x and y;
Solution:
y = 3x + 2 ----- (i)
y = -2x - 8 ------ (ii)
Using substitution method, input equation i, into ii
3x + 2 = -2x - 8
Collect like terms and solve;
3x + 2x = -8 -2
5x = -10
x = -2
Then put x = -2 into i, to find y
y = (-2 x 3) + 2
y = -6 + 2 = -4
So, the solution of the equation is B. (-2,-4)
Answer:
easy peasy
Step-by-step explanation:
u see,
the height of the airplane from the ground is 314m
but with the tower's horizontal plane, it would be
=> altitude of aircraft - height of tower
=> 314 - 70 = 244 m
now in the ABC,
using the ratio of sine,
sin 16 = AB/AC
=> 0.275 = 244/AC
=> AC = 244/ 0.275
=> AC = 887.9...
=> AC = approx. 886 meters
if she buys 10 of the small juice box packages and six of the yogurt treat packages then she should have an even number of both. That would be 60 of each.
Any number divided by 1 equals the original number.
See the attached picture:
It is 860.4 because if you multiply it in the calculator you will get the answer. So you put in 71.1 times 12 and you get 860.4.
