Answer:

graph A.

Step-by-step explanation:

So, y = 1/2x - 2 is only graphed in A and D.

And x ≤ 6 is only graphed in graph A.

The graph of the piecewise function is the first graph (counting from the top).

Here we have a piecewise function:

f(x) = 0.5*x - 2  if x ≤ 6

f(x) = -x - 1   if x > 6

So, we have an increasing line for x smaller or equal than 6, and a decreasing line for x > 6. Such that we should to have a closed dot at the end of the increasing line, because in that part we have the symbol ≥, meaning that x = 6 belongs to that part.

Then the correct graph is the first option.

Answer:

The range is 96.

Step-by-step explanation:

The definition of range is "The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set." So subtract the highest value from the smallest value,  and you get 96. pls mark brainliest.

Hope this helps.

Hello !

first, we need to find the smallest and the biggest number on the list:

4, 8, 13, 18, 22, 22, 47, 70, 77, 100

so it's 4 and 100

we substract the smallest from the biggest number :

100 - 4 = 96

96 is the range

Step-by-step explanation:

The complete problem is attached.

Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of

[tex]B=12 \times 12 = 144 \ in^{2}[/tex]

The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face

[tex]A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}[/tex]

But there are four triangle faces, so [tex]A_{faces} =4(66)=264 \ in^{2}[/tex].

Therefore, the area of each triangular face is 66 square inches.

So, the total surface area would be the sum

[tex]S=144+264=408 \ in^{2}[/tex]

Therefore, Gabriel needs 408 square inches to paint the whole model.

Let s represent the number of sofas and e  represent the amount earned.

We have been given that Mr. Gilmore sells furniture. He earned $210 for selling 3 sofas. Mr. Gilmore  earned $570 for selling 11 sofas. We are asked to write the equation for given scenario.

We have two points on a line that are (3,210) and (11,570).

Let us find slope of line passing through these points.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{570-210}{11-3}[/tex]

[tex]m=\frac{360}{8}[/tex]

[tex]m=45[/tex]

Now we will use point-slope form of equation.

[tex]y-y_1=m(x-x_1)[/tex], where

m = Slope,

[tex](x_1,y_1)[/tex] = Any point on line.

[tex]y-210=45(x-3)[/tex]

[tex]y-210=45x-135[/tex]

[tex]y-210+210=45x-135+210[/tex]

[tex]y=45x+75[/tex]

Since amount earned is e and number of sofas is s, so our equation would be [tex]e=45s+75[/tex].

Therefore, our required equation would be [tex]e=45s+75[/tex].

Answer:

12

Step-by-step explanation:

1. Write out s+14=26

2. Subtract 14 by both sides to isolate s.

3. s = 12

Answer:

s = 12

Step-by-step explanation:

s + 14 = 26

  - 14   - 14         Subtract 14 from both sides

s = 12

Plug this back into the equation to make sure it works

12 + 14 = 26        Add

26 = 26               This solution does work

Step-by-step explanation:

Answer:

C; D; B; B

Step-by-step explanation:

14) 1/((1/4) + (1/7)) = 1/(11/28) = 28/11 (C)

15) 1/((1/x) + (1/3x)) = 3--> (1/x) + (1/3x) = 1/3 --> 4/3x = 1/3 --> x = 4 (D)

16) 56 - 28 = 28 --> 28/(4*2) = 3.5 hours --> 56/3.5 = 16mph (when adding the stream's speed)--> 16mph - 4mph = 12mph (B)

17) 540 - 480 = 60 --> 60/(9*2) = 10/3 hours --> 540/(10/3) = 162 (when adding the current) --> 162mph - 9mph = 153mph (B)

How to Find the Mean

Add up all data values to get the sum

Count the number of values in your data set

Divide the sum by the count

The mean is the same as the average value in a data set.

Answer: A ) She only used the additive inverse of 10m when combining like terms .

Step-by-step explanation:

Holly only used the additive inverse of 10m when combining like terms. The equality is erroneous because the equation was evaluated well. The calculations should be as follows:

11m -13n + 6mn - 10m + 7n - 3mn = 1m - 6n +3mn

She should have subtracted 13n and 7n then take the negative value. Also, subtract 6mn and 3mn.

Hey there!

Since these angles share the same vertex (point where the lines that make the angle meet), they are congruent (they have the same value). Therefore, we can write the following equation.

4x-12=2x+48

We add 12 to both sides.

4x=2x+60

We subtract 2x from both sides.

2x=60

We divide both sides by 2.

x=30

Now, we can plug this in to find the measure of angle ACB. Whenever you see an angle that is named with three letters, the middle one is its vertex and the other two are the end points.

m∠ACB=4(30)-12

m∠ACB=120-12

m∠ACB=108

I hope that this helps! Have a wonderful day!

Answer:

4

Step-by-step explanation:

1/3 of 30 is 10

2/5 of 10 is 4

Answer:

vertex is (3,-4)

axis of symmetry is x=3

the Domain is all real numbers

the Range is all real numbers greater than or equal to -4

when x < 3, y increases as x decreases

when x > 3, y increases as x increases

We have been given that in triangle ABC angle A=45 angle B =40 and a=7. We are asked to find the equation that we can use to solve for 'f'.

We have two angles and opposite sides to these angles.

We will use Law of Sines to solve our given problem.

[tex]\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}[/tex], where a, b and c are opposite sides corresponding to angles A, B, and C respectively.

The angle opposite to side b is 40 degrees and angle opposite to side a is 45 degrees.

Upon substituting these values in Law of Sines, we will get:

[tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex]

Therefore, our required equation would be [tex]\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}[/tex].
