Answer:

-4×(2×1)=8x-2-4

solve in ( )

-4×3=8x-2-4

multiply -4 to 3

-12=8x-2-4

add 2 and 4 to both sides

-6=8x

divide -6 to 8 and you will get the answer

x=-0.75

Answer:

x = -0.25 (or) -1/4

Step-by-step explanation:

Let's solve the problem,

→ -4 × (2 × 1) = 8x - 2 - 4

→ -4 × 2 = 8x - 6

→ -8 = 8x - 6

→ 8x = -8 + 6

→ x = -2/8

→ [ x = -0.25 ]

Thus, solution is -0.25.

Answer: 80 degrees ==> 3rd option

Step-by-step explanation:

m<5=m<2   ==> angles 5 and 2 are opposite interior angles, so they're congruent.

m<2=38 degrees

m<2+m<6+m<3=180 degrees

38+62+m<3=180

100+m<3=180

m<3=80 degrees ==> 3rd option

The probability that a club member owns neither a house nor a car is 0.08 or 8%.

As per the survey of a club's members-

percentage of members who own a home 40% = 0.4

percentage of members who own a car → 90% = 0.9

Further, 95% of the homeowners also own a car

⇒ percentage of members who own a car as well as a home = 95% of 40%

= 95/100 x 40/100

= 3800/10000

= 0.38

Let P(A) be the probability that a member owns a home and P(B) be the probability that a member owns a car

we have,

P(A) = 0.4

P(B) = 0.9

also P(A∩B) = 0.38

we need to find the probability that a club member owns neither a house nor a car, that is, P(A'∩B')

According to the rules of probability-

P(AUB) = P(A) + P(B) - P(ANB)

⇒ P(AUB) = 0.4 +0.9 -0.38

P(AUB) = 0.92

Thus, P(A'U B') = 1 - 0.92

= 0.08

Thus, the probability that a club member owns neither a house nor a car is 0.08 or 8%.

The estimated result of 219 ÷ 15, by first rounding each number and then dividing, we get the result as 11.

We are given the expression:

219 ÷ 15

We need to estimate the result by first rounding off the digits to nearest tens and then performing division to get the answer.

So, we will first do the round off.

219 will be rounded off to 220

15 will be rounded off to 20

So, the expression will become:

220 ÷ 20

So, now performing the division, we get that:

= 11

Therefore, the estimated result of 219 ÷ 15, by first rounding each number and then dividing, we get the result as 11.

The equation has infinite solutions.

The value of x that makes the equation true is: 2. After substitution, we would have: 8 = 8

Another value of x that makes the equation true is: 3. After substitution, we would have: 10 = 10

If an equation has infinite solutions, it means that any value of the variable in the equation would make the equation true.

Given the equation, 2(x + 2) = 2x + 4, the value of x that makes the equation true is: 2.

Substitute x = 2 into the equation and simplify it would make both sides equal:

2(2 + 2) = 2(2) + 4

8 = 8

Another value of x that makes the equation true is: 3.

Substitute x = 3 into the equation and simplify it would make both sides equal:

2(3 + 2) = 2(3) + 4

Answer:x=1.

Step-by-step explanation:

3x-x+2=4

Infinitely many others are possible.

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

Explanation:

Replace x with 0 and simplify to get...

y = 3x-5

y = 3(0)-5

y = 0-5

y = -5

When x = 0, it leads to y = -5

One ordered pair is (x,y) = (0, -5)

Let's repeat those steps for x = 1

y = 3x-5

y = 3(1)-5

y = 3-5

y = -2

Another ordered pair is (1, -2)

As you can see, we can pick anything we want for x to get some paired y output. There are infinitely many x values to pick from. This means there are infinitely many ordered pairs for (x,y).

When it comes to graphing, you only need two points at minimum to form a straight line.

Answer: Average velocity = 11.1 m/s

Step-by-step explanation:

Given data,

A baseball is tossed up into the air at an initial velocity = 16 m/s​.

The height of the baseball at time t​ in seconds is given by,

                            h(t) =  16t - 4.9t²  ​​(in meters).

So,  

The average velocity is,            

To calculate the velocity travelled by the ball, differentiate the function.

                           dh/dt = 16 - 2(4.9t)

                           dh/dt = 16 - 9.8t               (eq-1)

Let us assume,    t = [1,1.5]​

Substitute t for 1 in the above Differential function

                            dh/dt = 16 - 9.8 (1)

But ,

                           dh/dt = velocity

So,                     dh/dt = V                        

                          V = 16 - 9.8

                          V =  6.2 m/s

Therefore,

               Average velocity = ( U + V ) / 2

               Average velocity = (16 + 6.2)/2

               Average velocity = 22.2/2

               Average velocity = 11.1 m/s

Hence, Average velocity = 11.1 m/s.

The domain of this function is (in order of least to greatest) is [-2,-1,0,3.5,4,5.5, and 8]

The range of this function is (in order from greatest to least) is [6,5.5,4,0,-1, and -3.5]

Step-by-step explanation:

To find the domain you need to look at all of you input or x values so the question is asking to name the values of x for your domain. You look at the table to where x is and name the numbers listed in this case it's [-2,-1,0,3.5,4,5.5, and 7]

To find the range you need to look at the listed outputs or y values. You are essentially doing the same steps but instead you looking at y for the listed values. Generally when it comes to domains that have the same range (for example (4,-1) and (5.5,-1)) you would only write it once in the list of ranges so like [6,5.5,4,0,-1, and -3.5]

Answer:

What are the options I can choose from?

Step-by-step explanation:

Use the definition of absolute value to rewrite each equation or inequality.

[tex]|x| = \begin{cases} x & \text{if } x\ge0 \\ -x & \text{if }x < 0 \end{cases}[/tex]

1. (E) From the definition it follows that

[tex]x-4 \ge 0 \implies |x-4| = x-4 = 8 \implies x = 12[/tex]

[tex]x-4 < 0 \implies |x-4| = -(x-4) = 4-x = 8 \implies x = -4[/tex]

Then the solution set contains exactly 2 elements, and we write it as shown in choice (E), [tex]x\in\{-4,12\}[/tex].

2. (D) We solve the inequality in essentially the same way as in (1), we just need to keep track of the direction of the inequality.

[tex]x-4\ge0 \implies|x-4|=x-4\ge8 \implies x\ge12[/tex]

[tex]x-4<0 \implies|x-4|=4-x\ge8 \implies x\le-4[/tex]

Note the inclusion of [tex]x=12[/tex] and [tex]x=-4[/tex]. We write this as a union of two half-closed intervals, [tex]x\in(-\infty,-4]\cup[12,\infty)[/tex].

3. (C) This follows from the same steps as in (2). This time the inequality is strict, so we exclude the endpoints and with open intervals write [tex]x\in(-\infty,4)\cup(12,\infty)[/tex].

4. (A) Since [tex]|x|[/tex] always returns a non-negative number, any real number [tex]x[/tex] satisfies the inequalty [tex]|x-4|<\infty[/tex]. We write the solution set as the entire real line, [tex]x\in(-\infty,\infty)[/tex].

5. This leaves us with (B) for the last solution set. This inequality is complementary to the one in (3), which means the solution set to [tex]|x-4|\le8[/tex] is the complement of the set we found in (3). That interval removes everything between and including -4 and 12 from the real line. So the solution in this case is what we omit from the solution to (3), and we write [tex]x\in[-4,12][/tex].
