Answer:
x + 8 <= 6, so x <= -2.
Step-by-step explanation
Greatest possible value of 7x is 7(-2) = -14.
Answer: $6019
Step-by-step explanation:
plug 8 into the equation -3223.31(multiply by 8 in place of x)+31805.58
and you'll get 6019.1 but it will only be right if you round to 6019
I took this assignment
5x - 5y = 10
x - y = 2 . . . (1)
3x - 2y = 2 . . . (2)
(1) x 3 => 3x - 3y = 6 . . . (3)
(2) - (3) => y = -4
From (1), x - (-4) = 2
x = 2 - 4 = -2
Solution is (-2, -4)
X=79/6 - 5y-6
Y=79/5 -6x/5
Answer:
B = 45°
BC = 14 km
AB = 14√2 km ≈ 19.80 km
Step-by-step explanation:
If one acute angle (A) of a right triangle is 45°, then the other one is also:
... 180° -90° -45° = 45°
The sides opposite these congruent angles are the same length, 14 km in this case, and the hypotenuse is found from the Pythagorean theorem to be √2 times either leg length.
... AB² = AC² +BC²
... AB = √(AC² +BC²) = (14 km)√(1² +1²) = 14√2 km
