Rebecca picked 1/4 bushel of blueberries yesterday. Today, she picked 7/9 of a bushel of blueberries. How much more did she pick

abruzzese [7]

Answer:

19/36 more than yesterday

Step-by-step explanation:

Since the denominators are different, multiply each fraction by the denominator of the other to be the same.

1/4 * 9 = 9/36

7/9 * 4 = 28/36

Now that the denominators are the same, you can subtract:

28/36 - 9/36 = 19/36

The function y=-x-3 is graphed only over the domain of (x1-8≤x≤ 8). What is the range of the graph?

irinina [24]

Answer:

B) $-5\leq y\leq -1$

Step-by-step explanation:

The range is the lowest point to the highest point on the graph.

Remember this:

1. domain (x-axis) LEFT –> RIGHT

2. range BOTTOM (y-axis) –> TOP

when this equation is graphed over the domain, it limits the range to being (8,–5) and (–8,–1) and since with range you only look at the y-coordinates that means that the range is [–5,–1]

Which Function has the graph below?

valentinak56 [21]

Answer:

Step-by-step explanation:

The general rule for the quadratic function is

$y=ax^2+bx+c$

From the graph you can see that the curve passes through the points (2,4), (1,7) and (3,7), so

$y(2)=4\Rightarrow 4=a\cdot 2^2+b\cdot 2+c\\ \\y(1)=7\Rightarrow 7=a\cdot 1^2+b\cdot 1+c\\ \\y(3)=7\Rightarrow 7=a\cdot 3^2+b\cdot 3+c$

We get the system of three equations:

$\left\{\begin{array}{l}4a+2b+c=4\\ \\a+b+c=7\\ \\9a+3b+c=7\end{array}\right.$

Subtract these equations:

$\left\{\begin{array}{l}4a+2b+c-a-b-c=4-7\\ \\9a+3b+c-a-b-c=7-7\end{array}\right.\Rightarrow \left\{\begin{array}{l}3a+b=-3\\ \\8a+2b=0\end{array}\right.$

From the second equation:

$b=-4a$

Substitute it into the first equation:

$3a-4a=-3\\ \\a=3$

So,

$b=-4\cdot 3=-12$

and

$3+(-12)+c=7\\ \\c=7+9=16$

The quadratic function is

$y=3\cdot x^2-12x+16$
