Answer: $=-17$

Step-by-step explanation:

The first thing you must remember is the mulplication of signs. You know that:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

You can observe that the number inside the parentheses is positive (+) and the sign that is outside the parentheses is negative (-), therefore, when you multiply these signs you get a negative sign (-). Then you get:

$-6-(11)=-6-11$

Now, you need to add these numbers. And the result obtained is:

$=-17$

Answer:

The true statement is D

Step-by-step explanation:

The rest of the question is the attached figure and the statement options.

A. Over the interval [–4, –2], the local minimum is 0.
B. Over the interval [–2, –1], the local minimum is 25.
C. Over the interval [–1, 4], the local minimum is 0.
D. Over the interval [4, 7], the local minimum is -7.

============================================================

According to the graph, we will check the options:

A. Over the interval [–4, –2], the local minimum is 0. (Wrong)

Because the minimum is -12

B. Over the interval [–2, –1], the local minimum is 25. (Wrong)

Because the minimum is 18

C. Over the interval [–1, 4], the local minimum is 0. (Wrong)

Because the minimum is at x = 4 less than zero

D. Over the interval [4, 7], the local minimum is -7. (True)

Cristiano is saving money to buy a bike that costs $189, He saved $99 so far. He plans on saving $10 each week. In how many week

yuradex [85]

Answer:

Cristiano will have enough money to buy bike in 9 weeks.

Step-by-step explanation:

Given:

Cost of the bike = $189

Money saved = $99

Money saving each week = $10

We need to find the number of weeks will he have money to buy bike.

Solution:

Let the number of weeks be 'x'.

Now we can say that;

Money saved plus money saving each week multiplied by number of weeks is equal to cost of the bike.

framing in equation form we get;

$99+10x=189$

Subtracting both side by 99 using subtraction property of equality we get;

$99+10x-99=189-99\\\\10x=90$

Dividing both side by 10 using division property of equality we get;

$\frac{10x}{10}=\frac{90}{10}\\\\x=9\ weeks$

Hence Cristiano will have enough money to buy bike in 9 weeks.

After the lunch rush, Ellen had used up all the small containers and half the large containers. Which of these expressions can b

Sergeu [11.5K]

Answer:

$Remaining\ containers=\frac{y}{2}\\\\Where\ y\ is\ the\ number\ of\ large\ containers.$

Step-by-step explanation:

Let number of small containers $=x$

Let number of large containers $=y$

Total containers $=x+y$

Used Containers:

Small containers used $=x\ \ \ (as\ all\ small\ containers\ used)$

Larger containers used $=\frac{y}{2}\ \ \ \ \ \ (half\ of\ the\ large\ containers\ used)$

Total containers used $=x+\frac{y}{2}$

Remaining containers=total containers-used containers

$Remaining\ containers=(x+y)-(x+\frac{y}{2})=\frac{y}{2}\\\\\\\\If\ small\ containers(x)=30\\\\Large\ containers(y)=20\\\\total\ containers(x+y)=30\\\\Remaining\ containers=30-10-\frac{1}{2}\times 20$
