Answer:

7x+1

Step-by-step explanation:

When you look at the expression(3x+2+4x-1), you will notice that some have variables while some are just regular numbers.

First, focus on the variables. 3x and +4x. In the expression, you will have to add it so 3x+4x will be 7x. Now, keep 7x on the side and switch to the numbers.

Next, focus on the numbers. 2 and -1. All you have to do is combine them which will be 2-1 which also equals 1.

Finally, return 7x with 1 which will be 7x+1. The reason you add a + sign instead of a - sign is because you got positive 1, not negative 1.

Your answer is 7x+1.

Answer:

9,0

Why?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Answer: 5

Step-by-step explanation:

Since we know that equal number of dashes will always be equal to another we can easily solve the question. They said AB=8 and as you can see 8 is represented by two dashes here and if we take in what i said earlier,, that means DC= 8 too. They also said AD= 5. Since 5 is represented by one dash we can easily see that since BC also has one dash,, it is going to be equal to AD which concluded to the answer of 5.

What is Substitution method?

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

The expressions are;

1. 16

2. n - 2

3. 1/16

4. 1/n²

Now, Put n = 4 in all given expression we get;

The first expression is,

16

The second expression is,

n - 2

= 4 - 2

= 2

The third expression is,

1/16

The fourth expression is,

1/n²

= 1/4²

= 1/16

Hence, Third and fourth expression are same.

So, For n = 4, all of the given expressions are equivalent except 16 and

(n - 2).

Answer:

Step-by-step explanation:

In this exercise, for us to find the speed that Chloe drives with we need to first convert the time she spent driving to hours completely since the time given is in hours and minute

Data

distance= 64 mile

time= 1hr 35min

to covert 1 hr 35 min to hours we have

= 1 + 35/60 (we are converting 35 min to hrs)

= 1+0.583

=  1.583

hence speed= 64/ 1.583

speed= 40.42 mph

She was driving at 40.42 mph on average

About 40 miles per hour

Step-by-step explanation:

Answer:

Y(0, - 14 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Use the midpoint formula and equate corresponding parts to the coordinates of the given midpoint

let Y = (x, y ), then

[tex]\frac{1}{2}[/tex] (4 + x) = 2 ( multiply both sides by 2 )

4 + x = 4 ( subtract 4 from both sides )

x = 0

and

[tex]\frac{1}{2}[/tex] (4 + y ) = - 5 ( multiply both sides by 2 )

4 + y = - 10 ( subtract 4 from both sides )

y = - 14

Thus

coordinates of Y = (0, - 14 )

Complete Question

A field in the shape of a trapezoid has an area of 13,687.5 square yards the length of one base is 150 yards and the length of the other base is 215 yards what is the height of the trapezoid

Answer:

The height of the trapezoid is 75 yards

Step-by-step explanation:

Area of a Trapezoid = 1/2(b1 + b2) × h

Where b1 = Length of the first base

b2 = Length of the second base

h = height of the trapezoid

From the question

Area of the trapezoid = 13,687.5 yd²

b1 = Length of the first base = 150 yards

b2 = Length of the second base = 215 yards

h = height of the trapezoid

Hence, we have

13,687.5 = 1/2(150 + 215)h

13,687.5 = 365h/2

13,687.5 × 2 = 365h

h = 13687.5 × 2/365

h = 75 yards

Therefore, the height of the trapezoid is 75 yards.

Answer:

8 1/6

Step-by-step explanation:

5/6 + 7 1/3

Change the fractions to different denominators.

5/6 x 1/1 = 5/6

1/3 x 2/2 = 2/6

5/6 + 2/6 = 7/6

7/6 = 1 1/6

1 1/6 + 7 = 8 1/6

Answer:

0.4285714286.

The hundredth place is 2 places to the right of the decimal. In this case, it is 2. So we look to the number to the right of 2 (which is 8). 8 ≥ 5, so the 2 gets rounded to a 3.

0.43

Answer:

The answer is 0.43

Step-by-step explanation:

When you divide 3 by 7, you get 0.42857142857142857142857142857143.

To round to the nearest hundredth, you go 2 numbers after the decimal place. The number on the right of the 2nd number (which is in the hundredths place) will either make the number round up or down. Since the number 8 is greater than 5, the number rounds up.

So, the answer will be 0.43

Answer

x=4

Step-by-step explanation:

4x-1=3x+3 because both sides are equal, since M is a midpoint.

Subtract 3x to both sides to get x-1=3.

Add 1 to both sides to get x=4.

Answer:

[tex]\huge\boxed{\sf x = 4}[/tex]

Step-by-step explanation:

If M is the midpoint of VW.

Then,

WM = MW

Given that WM = 4x - 1 and MW = 3x + 3

So,

4x - 1 = 3x + 3

Combining like terms

4x - 3x = 3 + 1

x = 4

Answer: 4

Step-by-step explanation:

Answer:

p = 1.5

Step-by-step explanation:

— 7 + 4p = -8p + 11

Add 8p to each side

— 7 + 4p+8p = -8p+8p + 11

-7 +12p = 11

Add 7 to each side

-7+7 +12p = 17

12p = 18

Divide each side by 12

12p/12 =18/12

p = 18/12

p = 3/2

p = 1.5

Answer:

x=-8

Step-by-step explanation:

-3(3x+8)+2=26-3x

We move all terms to the left:

-3(3x+8)+2-(26-3x)=0

We add all the numbers together, and all the variables

-3(3x+8)-(-3x+26)+2=0

We multiply parentheses

-9x-(-3x+26)-24+2=0

We get rid of parentheses

-9x+3x-26-24+2=0

We add all the numbers together, and all the variables

-6x-48=0

We move all terms containing x to the left, all other terms to the right

-6x=48

x=48/-6

x=-8
