Answer:

Step-by-step explanation:

Domain means what is the lowest value of x on the graph and what is the highest. Our graph begins at an x value of -5 (but -5 is not included because the dot is not filled in) and goes all the way up to 2 (but 2 is not included either since the dot is not filled in. Therefore, the domain is

D = {x | x ∈ R, -5 < x < 2}

which means that the domain is in the set of real numbers that begin at -5 and end at 2, neither included.

Choice F is the one you want.

2x + 4a = 10

2x = 10 - 4a

x = 5 - 2a

B is the answer for this question due to the value of root and that's is root under 20

Answer:

Point B represents the location of

[tex] \sqrt{20} [/tex]

Step-by-step explanation:

As the value of under root 16 is 4 and the value of under root 25 is 5

So the location of under root 20 will be in between 4 and 5 on the number line

Answer:  (1.125,-0.25)

Step-by-step explanation:  The point that is the same for both equations is the point where they intersect.  It appears from the graph to be around (1,0).  We should confirm this by deriving the equation for each line and then solving them.  Use the standard format:  y = mx+b, where m is the slope and b the y-intercept.

I calculate the 1st line (angled down to the right) to have a slope (m) of -2 [y drops 2 for every increase of 1 for x).  The y intercept is 2 (b).  This equation would be y = mx+b, or y = -2x + 2.

The second line has a positive slope of 2/3 and a y intercept of -1, y = (2/3)x-1

Set these two equations equal to each other and solve for x.

-2x+2=(2/3)x-1

x = 1.125

Use that value of x to solve for y:  y = -0.25

The point of intersection is therefore (1.125, -0.25)

Answer:

A. The weight of the apples is a function of their cost.

Step-by-step explanation:

In the graph it shows the more the apples weight the cost increase, therefore A is your answer.

Answer:

-17

Step-by-step explanation:

First, let's see what the value of w is, by solving -5w - 5 = 5.

-5w - 5 = 5            Add 5 on both sides.

-5w = 10                Divide -5 on both sides.

w = -2

Now, we know that w is equal to -2, let's plug it in to find the value.

9(-2) + 1                 Distribute.

-18 + 1                    Add.

Answer:

0.1875, or [tex]\frac{3}{16}[/tex]

Explanation:

Using the formula [tex]a_n=\frac{24}{2^{n-1} }[/tex], where [tex]n = term[/tex], we find

[tex]a_8 = 0.1875[/tex]

Step-by-step explanation:

Since all side lengths of smaller squares are equal, we have

[tex]3x+4=4x-1[/tex]

[tex]x=5[/tex]

Since length of AB is twice of the side length of smaller squares,

[tex]\bar{AB}=2(3x+4)=2(3\cdot5+4)=38[/tex]

Answer:

AB=38

Answer:

x = -2/7 or

x = 6/7

Step-by-step explanation:

|7x-2| + 3 = -1  subtract 3 from both sides

|7x-2| = -4 now there are two probabilities

7x-2 = -4 or

7x-2 = 4 if first probability the value of x would be:

7x-2 = -4 add 2 to both sides

7x = -2 divide both sides by 7

x = -2/7 for the second probability the value of x would be:

7x-2 = 4 add 2 to both sides

7x = 6 divide both sides by 7

x = 6/7

Answer:

9 hours

Step-by-step explanation:

Step-by-step explanation:

If the figure is triangle then,

Let PR be x

So,

PQ+QR+PR= 180 (Sum of all the angles of the triangle)

Therefore,

6x+25+16-3x+x=180

4x+36=180

4x= 180/36

x= 144/4

X= 36

NOW,

PQ= 6x+25

= 6(36)+25

= 216+25 = 241= PQ.

QR = 16-3x

= 16-3(36)

= 16-108

= -92

PR = 36

hope it helps

PR = 36
