Solve for the unknown variable ​

Answer:

The variable representation is x, x+2 and x+4 for this sequence.

Step-by-step explanation:

Given that:

The sum of 3 consecutive even numbers is 78.

Let,

The first even number is represented by x.

As the numbers are consecutive, thus,

First even number = x

Second even number = x+2

Third even number = x+4

Hence,

The variable representation is x, x+2 and x+4 for this sequence.

Answer: $1.25

Step-by-step explanation:

Given

Graham spends a total of $15.05 on 10 apples and a packet of strawberries

Cost of strawberries packet $2.55

Suppose the cost of each apple is x

So, [tex]10x+2.55=15.05[/tex]

On solving

[tex]\Rightarrow10x=15.05-2.55\\\Rightarrow10x=12.5\\\Rightarrowx=\frac{12.5}{10}=\$1.25[/tex]

The cost of each apple is $1.25

There are 4 quarts in a gallon so if you multiply 4 by 2 then you get 8,

Answer:

8 quarts

Step-by-step explanation:

1 gallon is equal to 4 quarts, so from there you just multiply 2 times 4 and you get 8 !

Answer:

It falls to the left and rises to the right.

Step-by-step explanation:

The polynomial function is given as;

g(x) =10x^(9) - 50x^(6) - 500x²

In this polynomial, the leading coefficient is 10. This is positive and also an even number and thus it means the graph will rise to the right.

Also, the degree of the polynomial is 9 since that's the highest degree of x. This degree is odd and it means the graph will point in the opposite direction to that of the leading coefficient. Thus, we can say it falls to the left.

So in summary, the end behavior of the graph of g is that it falls to the left and rises to the right.

The end behavior of the polynomial is:

The first thing you need to notice is that the degree of the polynomial is odd. This means that the function will have two opposite end behaviors.

Also, the leading coefficient is positive (is 10). So, when x tends to positive infinity, the end behavior of the function will tend to positive infinity.

When x tends to negative infinity, because the exponent is odd, the outcome will also be negative. Then here the end behavior of the function will tend to negative infinity.

Concluding, we can write:

Answer:

250 jars

6 hours

Step-by-step explanation:

We know they make 50 jars in an hour, so 50 times 5 is 250 jars in 5 hours. Since 300 is 50 more than 250, and we know 50 times 6 is 300, we can say that we would need 6 hours to make 300 jars.

Answer:

The point-slope equation of the line is y - 2 = 3(x + 9)

Step-by-step explanation:

The form of the point-slope equation is y - y1 = m(x - x1), where

∵ The slope of a line is 3

∴ m = 3

∵ The line passes through point (-9, 2)

∵ x1 = -9

∴ y1 = 2

→ Substitute the values of m, x1, and y1 in the point-slope form

∵ y - y1 = m(x - x1)

∴ y - 2 = 3(x - (-9))

→ Remember (-)(-) = (+)

∴ y - 2 = 3(x + 9)

∴ The point-slope equation of the line is y - 2 = 3(x + 9)

Answer:

Yes

Step-by-step explanation:

Yes, when you purchase a life insurance policy you will be charged a certain rate but this can change if there are sudden changes in your health or as you get older. In some cases, you may purchase an insurance policy for a certain amount of years in which the rate is guaranteed to remain the same during that time. This type of policy's rate depends on the period of time you choose to be insured but once the time period is over the rate can increase a lot depending on your age and health at that time.

Answer:

87

Step-by-step explanation:

Hi!

First you add all of the numbers up together:

77+81+93+97= 348

Next, you divide the answer you got above by how many numbers are in your data set:

348/4 = 87

4 because 77,81,93,97 thats four numbers :)

Therefore, Marla's test average is 87!

So anytime you need find the average of any data set, you just add all the numbers together, then divide by the quantity of numbers there are.

Answer:

x = 4

Step-by-step explanation:

Since the rectangles are similar, use a ratio.

15/6 = 10/x

or

6/15 = x/10

I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.

15/6 = 10/x

Cross Multiply:

6(10) = 15x

Awnser C      9x + 7x

Step-by-step explanation:

the perimiter of that triangle is 16x   9x + 7x = 16x

Answer:

The required graph is shown below.

Step-by-step explanation:

Consider the given system of linear equations.

[tex]y=x+4[/tex]

Put x=0 in the above equation.

[tex]y=0+4[/tex]

[tex]y=4[/tex]

Now, put y=0 in [tex]y=x+4[/tex].

[tex]0=x+4[/tex]

[tex]x=-4[/tex]

The coordinates are (0,4) and (-4,0). Draw the line by using the points.

Similarly,

Consider the equation [tex]y = 3x - 1[/tex]

Put x=0 in the above equation.

[tex]y=3(0)-1[/tex]

[tex]y=-1[/tex]

Now, put y=0 in [tex]y = 3x - 1[/tex].

[tex]0=3x-1[/tex]

[tex]x=\frac{1}{3}[/tex]

The coordinates are (0,-1) and ([tex]\frac{1}{3}[/tex],0). Draw the line by using the points.

The required graph is shown below.

Answer:

2(x + 3) = 2x + 6

Step-by-step explanation:

Here, we want to expand

2(x + 3)

To do this, we simply multiply the term outside the bracket with each of the terms inside it

That will be;

(2 * x ) + (2 * 3)

= 2x + 6

Answer:

x = 12

A = 30

Step-by-step explanation:

Here, we want to solve for the value of x

The angle at the top of the triangle is 8x + 4

The reason for this is because vertically opposite angles are equal

Mathematically;

8x + 4 + 3x - 6 = 130

The reason for this is that opposite interior angles equal the exterior angle

Thus;

8x + 3x + 4- 6 = 130

11x -2 = 130

11x = 130 + 2

11x = 132

x = 132/11

x = 12

The value of A is 3x - 6

A = 3(12)-6

A = 36-6

A = 30

Answer: ↓↓↓

Step-by-step explanation:

1. a = ?   b = 16  c = 18

a² + b² = c²

a² + (16)² = (18)²

a² +  256 = 324

     - 256   -256

a² = 68

√a² = √68

a ≈ 8.25

2. a = 4     b = 8     c = ?

a² + b² = c²

(4)² + (8)² = c²

16 + 64 = c²

80 = c²

√c² = √80

c ≈ 8.94
