The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:

Step-by-step explanation:

Given the sequence

9, 17, 25, 33

a₁ = 9

Determining the common difference

d = 17-9 = 8

d = 25-17 = 8

d = 33-25 = 8

As the common difference between the adjacent terms is same and equal to

d = 8

Therefore, the given sequence is an Arithmetic sequence.

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting a₁ = 9, d = 8 in the equation

[tex]\:a_n=9+8n-8[/tex]

[tex]a_n=8n+1[/tex]

Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:

i suggest look up a number chart similar to that and place the (4,4) on it

Step-by-step explanation:

im sorry if i couldnt help

Answer:

m is the slope, so it has a slope of 1. it gave you a point so it wants you to plug the point and slope into point-slope form and then solve for the equation to be in slope-intercept form so you can graph it.

point-slope form is: y -y1 = m(x -x1)

plug in the given values and solve

y - 4 = 1(x -4) (use the distributive property to get rid of the parenthesis)

y -4 = 1x - 4 (add 4 to both sides to isolate y)

y = 1x  (1x is the same as x, so it's redundant to write 1x)

y= x (this is the equation of the line)

if you don't know how to graph y=x, whatever the y value is, the y value is. it's a straight line going through the origin.

Answer:

Answer:

48 flowers.

Step-by-step explanation:

You know that there are red, purple, pink, and yellow flowers in the garden. Since you know that 1/2 are red and 1/4 are purple, the pink and yellow flowers (combined) must make up the remaining 1/4 of the garden.

You're told in the problem that of this remaining 1/4, 2/3 are pink. That must mean 1/3 are yellow. There are twice as many pink flowers as yellow flowers.

The problem also says there are 4 yellow flowers. This means that 1/3 (of the remaining 1/4) is equal to 4.

To figure out how many pink flowers there are, you can multiple 4 x 2. There must be 8 pink flowers.

To find the total number of pink and yellow flowers, add 8 + 4. There are 12 pink and yellow flowers.

Remember that the pink and yellow flowers must make up the remaining 1/4 of the garden. If 12 flowers is equal to 1/4 of the garden, then you can multiply by 12 x 4 to figure how many flowers are in the entire garden: 48 flowers.

Answer:

35

Step-by-step explanation:

The number of students in Mr.Romano’s class is 35.

Given that, in Mr. Romano‘s class, 40% of the students like baseball.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of students in Mr.Romano’s class be x.

Here, 40% of x = 14

⇒ 40/100 × x = 14

⇒ 0.4x = 14

⇒ x = 14/0.4

⇒ x = 35

Therefore, the number of students in Mr.Romano’s class is 35.

Answer:

15.20feet

Step-by-step explanation:

Length of the ladder = 16foot (hypotenuse)

BAse of the ladder from the house = 5feet (adjacent)

height of the house = x (opposite)

Using the pythagoras theorem

hyp^2 = opp^2 + adj^2

16^2 = 5^2 + opp^2

256 = 25 + opp^2

opp^2 = 256-25

opp^2 = 231

opp =√231

opp = 15.20

Hence the house is 15.20feet high up the house

Answer:

p=−12x2+8x+−492

is what I got

The value of p must be 7 for the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54.

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

It is given that the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54

That is (x - p)^2 + 5 = x^2 – 14x + 54

Solving for p;

x^2 + p^2 + 5 - 2px =  x^2 – 14x + 54

Combine the like terms;

p^2 + 5 - 2px =– 14x + 54

p^2 - 2px + 14x - 49 = 0

If we put p = 7 then

49 - 14x + 14x - 49 = 0

Therefore, the value of p must be 7 for the expression (x - p)2 + 5 equivalent to the expression x2 – 14x + 54.

Hello!

[tex]\large\boxed{x = 17}[/tex]

[tex]\sqrt{x -1} + 5 = 9[/tex]

Begin by subtracting 5 from both sides:

[tex]\sqrt{x -1} = 9 - 5\\\\\sqrt{x -1} = 4[/tex]

Square both sides to get rid of the radical:

[tex]x - 1 = 16[/tex]

Add 1 to both sides to completely isolate for x:
