You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3
(x-3)^2 + (x+5)^2=9^2
(x^2-6x+9) + (x^2+10x+25)=81
2x^2+4x+34=81
2x^2+4x-47=0
From here just use quadratic formula
Answer:
B
Step-by-step explanation:
Given
7x - 9 > 2x + 6 ( subtract 2x from both sides )
5x - 9 > 6 ( add 9 to both sides )
5x > 15 ( divide both sides by 3 )
x > 3 → B
Answer:
D. Negative slope
Step-by-step explanation:
Since it is a proportional relation, it must be linear. A line has a slope. Since it is decreasing, it is a negative slope.
