Answer:
f(-4) = 33
f(7) = -154
Step-by-step explanation:
In this question, you will solve the function by plugging in the given value.
Solve:
f(-4) = 7 - 2(-4) -3(-4)²
= 7 - 2(-4) - 48
= 7 + 8 - 48
= 7 - 40
f(-4) = 33
----------------------------------
f(7) = 7 - 2(7) -3(7)²
= 7 - 2(7) - 147
= 7 - 14 - 147
= 7 - 161
f(7) = -154
Length = √(y2-y1)² + (x2-x1)²
l = √(-4+4)² + (11+12)²
l = √23²
l = 23
In short, Your Answer would be 23 units
Hope this helps!
Answer:
Slope: -1/3
Y-intercept: 0
Step-by-step explanation:
The lines passes the y-axis at 0, and since the line is going downwards, the slope will be negative.
I hope it helps! Have a great day!

<span>Muffins cost $1.25 and bagels cost $0.80.
We know by addition that 15 bagels and 12 muffins would cost $27. We can divide each term by 3 to simplify this and see that 5 bagels and 4 muffins would cost $9. Since we already knew that 5 bagels and 8 muffins cost $14, we can use subtraction to discover that 4 muffins cost $5. By dividing both sides of the equation by 4 we learn that a muffin costs $1.25. Once we know this we can plug this back into any equation to derive the cost of a bagel. For example 10b + (4 x 1.25) = 13, so 10b = 13 - (4 x 1.25), so, b = [13 - (4 x 1.25)]/10, so b = 0.80.</span>
