Answer:
$46.25 ÷ $9
Step-by-step explanation:
I don't have the first answer sorry but I do know the second answer, you add up 7+4 which gives you 11 then it asked you about the odds in favor of picking green marble, the answer is 7:11
3x + 5y = 29 first equation
y = -4x - 1 second equation
substitute the second equation to the first equation;
3x + 5(-4x - 1) = 29
-17x - 5 = 29
solve for x;
-17x - 5 = 29
-17x = 34
x = -2
substitute x = -2 into the second equation to find y;
y = -4x - 1
y = -4(-2) - 1
y = 8 - 1
y = 7
so;
x = -2, y = 7
hope this helps, God bless!
Answer:
B. (-4,0) and (-3,0)
Step-by-step explanation:
I used a graphing tool to graph the equation. The parabola intercepts at (-4,0) and (-3,0). Therefore, (-4,0) and (-3,0) are the x-intercepts of the equation.
Option B should be the correct answer.
