What is the 15th term of the following sequence? -0.25, 0.5, 1.25, 2, 2.75...

Answers

Answer 1

Answer:

The 15th term is 10.25

Step-by-step explanation:

Sequences

The given sequence:

-0.25, 0.5, 1.25, 2, 2.75...

can be categorized as an arithmetic sequence. To better know, we try to find a common difference between successive terms:

0.5 - (-0.25) = 0.75

1.25 - 0.5 = 0.75

2 - 1.25 = 0.75

Once we are certain it's an arithmetic sequence, we find the general term by using the formula:

[tex]a_n=a_1+(n-1)r[/tex]

Where n is the number of the term, a1 is the first term, and r is the common difference. We have already found that:

r=0.75

a1=-0.25

The 15th term (n=15) is:

[tex]a_{15}=-0.25+(15-1)*0.75[/tex]

[tex]a_{15}=-0.25+14*0.75[/tex]

[tex]a_{15}=-0.25+10.5=10.25[/tex]

The 15th term is 10.25

It seems that when x = 1, f(x) is both 4 and 5.

While two different x values can equal the same y value, one single x value cannot be equal to more than one value.

If this was a function that could be graph, there would be an extra dot at (1, 4) or (1, 5) since 1 is equal 4 or 5. This is why it is not a function.

(5/9 multiplied by -4) + (3/4 multiplied by -6) is ? Please please help ill give brainiest!!

Answers

Answer:

- 6 13/18

Step-by-step explanation:

5/9 times -4 is -20 over 9     -20/9     -2 2/9

3/4 times -6 is -18 over 4     -18/4         -4 1/2

You need them to have a common denominator

so you can multiply the first answer by 4 and the second by 9.

You get -242/36 after a while

and then

you simplify.

You can multiply 36 six times  into -242 so you get the whole number of 6 plus 216

242-216 is 26

26 over 36 is 13 over 18

-6 13/18

Given lines p and q are parallel, m<2 - (14x - 12), m<6 - (5y + 23), and m<8 - (8x + 27), solve for the values of x and y then solve for the measure of each angle

Answers

Answer:

x = 7.5

y = 14

m<1 = 87°

m<7 = 93°

Step-by-step explanation:

Given:

m<2 = (14x - 12),

m<6 = (5y + 23),

m<8 = (8x + 27)

m<2 + m<8 = 180° (consecutive exterior angles are supplementary)

(14x - 12) + (8x + 27) = 180 (substitution)

Solve for x

14x - 12 + 8x + 27 = 180

Collect like terms

22x + 15 = 180

Subtract 15 from each side

22x = 180 - 15

22x = 165

Divide both sides by 22

x = 7.5

m<2 = m<6 (corresponding angles are congruent)

(14x - 12) = (5y + 23) (substitution)

Plug in the value of x

14(7.5) - 12 = 5y + 23

105 - 12 = 5y + 23

93 = 5y + 23

Subtract 23 from each side

93 - 23 = 5y

70 = 5y

Divide both sides by 5

14 = y

y = 14

✅m<1 = m<8 (alternate exterior angles are congruent)

m<1 = (8x + 27) (substitution)

Plug in the value of x

m<1 = 8(7.5) + 27 = 87°

m<7 = m<2 (alternate exterior angles are congruent)

m<7 = (14x - 12) (substitution)

Plug in the value of x

m<7 = 14(7.5) - 12 = 93°

What is the equation of this line?

Answers

Answer:

y= -5/4x + 6

Step-by-step explanation:

y= mx + b

m= -5/4 (rise over run/slope)

b= 6 (y-intercept)

-I hope this helps have a great day!

Answer:

y = -5/4(x)+6

Step-by-step explanation:

to find the equation of this line, we must first find the slope

We can write the equation of this line y = mx + b where m is the slope and b is the y-intercept

m = (y2-y1)/(x2-x1)

m = (-4-6)/(8-0)

m = -10/8

m = -5/4

b is the y intercept which is at 6

So the equation of the line is y = -5/4(x)+6
