Can someone please help?

Answer:

1. x+4x

2. 5x

3. $6\frac{7}{x}$

4. 4x-2x+15

5. $(6+x)^2$

Step-by-step explanation:

To write expressions remember these key words:

a number is a variable like x
sum is +
difference and subtracted is -
quotient is ÷
product is ×
reciprocal means flip like $\frac{1}{9}---> \frac{9}{1}$
square is an exponent of 2 like $x^2$

1. x+4x

2. 5x

3. $6\frac{7}{x}$

Remember a quotient would be $\frac{x}{7}$ but the reciprocal is $\frac{7}{x}$ .

4. 4x-2x+15

5. $(6+x)^2$

The graph of an absolute value function contains the points (–3, 5), (0, 2) and (3, 5). Which could be the function represented

Alex73 [517]

The absolute value functions that contains the points are:

f(x) = |x| + 2
f(x) = |-x| + 2

<h3>Which could be the function represented by this graph?</h3>

Here we have the points (-3, 5), (0, 2), and (3, 5). We want to see which ones of the given functions have that points.

To check that, we need to evaluate the functions in the first value of each point and see if the outcome is the second value of the correspondent point.

For example, for the first equation:

f(-3) = |-3| + 2 = 5 so it has the point (-3, 5)
f(0) = |0| + 2 = 2 so it has the point (0, 2)
f(3) = |3| + 2 = 5 so it has the point (3, 5).

The other option that also contains these 3 points is:

f(x) = |-x| + 2

f(-3) = |3| + 2 = 5 so it has the point (-3, 5)
f(0) = |-0| + 2 = 2 so it has the point (0, 2)
f(3) = |-3| + 2 = 5 so it has the point (3, 5).

And all the other options can be trivially discarded (by evaluating them).

So the two correct options are:

f(x) = |x| + 2
f(x) = |-x| + 2

a rectangle has an area of 54 square inches the width of the rectangle is 9 inches what is the langth

STatiana [176]

Answer:

As per Provided Information

Area of rectangle is 54 square inches
Width of the rectangle is 9 inches.

We have to calculate the length of rectangle .

As we know the formula to find the Area of rectangle .

$\boxed{\bf \: Area_{(Rectangle)} = length \: \times width}$

On substituting the value we obtain

$\sf \qquad \: \longrightarrow 54 = length \times 9 \\ \\ \\ \sf \qquad \: \longrightarrow \cfrac{54}{9} = length \\ \\ \\ \sf \qquad \: \longrightarrow \: length \: = \cfrac{54}{9} \\ \\ \\ \sf \qquad \: \longrightarrow \: length \: = \cancel \cfrac{54}{9} \\ \\ \\ \sf \qquad \: \longrightarrow \: length \: = 6 \: inches$

Therefore,

Length of the rectangle is 6 inches .

<h3>Answer: Angle Q = 133 degrees</h3>

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

Work Shown:

Recall that for any triangle, the three angles always add to 180

P+Q+R = 180

(x+13) + (10x+13) + (2x-2) = 180

(x+10x+2x) + (13+13-2) = 180

13x+24 = 180

13x = 180-24

13x = 156

x = 156/13

x = 12

Now that we know x, we can find the angle measures

angle P = x+13 = 12+13 = 25 degrees
angle Q = 10x+13 = 10*12+13 = 120+13 = 133 degrees
angle R = 2x-2 = 2*12-2 = 24-2 = 22 degrees

As a way to check if we have the right answer or not, we see that,

P+Q+R = 25+133+22 = 180

So the answer is confirmed.
