For this case we must indicate the inequality represented in the graph.

It is noted that we have a closed point at -1, so the inequality at that point contains equality and is represented by "[". On the other hand, we observe an open point at +3, so inequality does not include equality (does not include +3) and is represented as ")".

So, the interval of the graph is:

$[-1,3)$

This is equivalent to:

$-1 \leq t$

Answer:

Option B

Elena L [17]

The number of apples is x, and the number of oranges is y.

"Mia needs to bring at least 25 pieces of fruit to the school picnic."

means that x+y≥25

"She was told to be sure to bring more than 10 apples."

means that x≥10

thus, the inequalities are:

i) x+y≥25

ii) x≥10

Add and simplify 9/16 + 1/2 =

harkovskaia [24]

$\boxed{\boxed{ \ \frac{9}{16} + \frac{1}{2} = \frac{17}{16} = 1\frac{1}{16} \ }}$

<h3>Further explanation</h3>

We will work on adding two fractions correctly with different denominators. The two denominators must be equated first.

In order to add these fractions, we need finding the common denominator by multiplying both denominators together.

$\boxed{\frac{9}{16} + \frac{1}{2} = \ ?}$

Both denominators, 16 and 2, are multiplied by one another. What about numerators? Pay attention to the treatment of each fraction.

$\boxed{= \big( \frac{9}{16} \times \frac{2}{2} \big) + \big( \frac{1}{2} \times \frac{16}{16} \big)}$

$\boxed{= \frac{18}{32} + \frac{16}{32}}$

$\boxed{= \frac{34}{32}}$

Let's take a break here to think.

Alternatively, develop a sharper method as below.

$\boxed{= \frac{(9 \times 2) + (16 \times 1)}{16 \times 2}}$

Note how this is performed. Absolutely indeed, cross-multiplication!

$\boxed{= \frac{18 + 16}{32}}$

$\boxed{= \frac{34}{32}}$

The numerator and denominator are divided by two to make it a simple fraction. After that, we simplify again into mixed fractions.

$\boxed{\boxed{ \ \frac{9}{16} + \frac{1}{2} = \frac{17}{16} = 1\frac{1}{16} \ }}$

Gently let's take a break once more to think strategically.

Observing the steps above, we still find a large number when there is a direct multiplication of the two denominators. Are there more highly recommended steps? Of course there is!

$\boxed{\frac{9}{16} + \frac{1}{2} = \ ?}$

The denominators 2 and 16 have LCM = 16. So, we convert the given fractions into equivalent fractions with denominator 16.

$\boxed{= \big( \frac{9}{16} \times \frac{1}{1} \big) + \big( \frac{1}{2} \times \frac{8}{8} \big)}$

$\boxed{= \frac{9}{16} + \frac{8}{16}}$

$\boxed{= \frac{17}{16}}$

Do not forget simplifying again into mixed fractions.

$\boxed{\boxed{ \ \frac{9}{16} + \frac{1}{2} = \frac{17}{16} = 1\frac{1}{16} \ }}$

In the form of fractions, the steps that must be considered are

equate the denominator,
simplify fractions, and
for the final answer, convert fractions to mixed fractions or decimal forms
