y = –⁷⁄₉x + 5

+ ⁷⁄₉x + ⁷⁄₉x

___________

⁷⁄₉x + y = 5 [We CANNOT leave the equation like this, so multiply by 9 to eradicate the fraction.]

9[⁷⁄₉x + y = 5]

$\displaystyle 7x + 9y = 45$

Answer: The area of Figure ABCDE is 79.5 square units.

Step-by-step explanation:

Triangle ABC is the top triangle of Figure ABCDE.

Triangle ACD is the triangle on the right of Figure ABCDE.

Triangle AED is the triangle on the bottom left of Figure ABCDE.

So, we need to add 23.85, 29.4, and 26.25 to get the area of Figure ABCDE!

23.85 + 29.4 + 26.25 = 79.5

Answer:

3 minutes

5 minutes.

Step-by-step explanation:

It is given that, Amelia can wash 8 plates in 24 minutes.

So, if this rate remains constant then 1 plate will be washed in $\frac{24}{8} = 3$ minutes.

Again, it is given that, Amelia bakes 12 cookies in 60 minutes.

So, if this rate also remains constant then she will bake 1 cookie in $\frac{60}{12} = 5$ minutes. ( Answer )

gtnhenbr [62]

Answer:

[-20.25;+∞).

Step-by-step explanation:

1) according to the properties of the given parabola the minimum is:

$x_0=-\frac{-7}{2}=3.5; \ y_0=-20.25;$

2) y₀=-20.25 means, the value -20.25 is minimum of the range, the maximum →+∞;

3) finally, the range y≥-20.25.
