I'm not sure I'm right, I'm not all that good at elimination but I think the answer is y = 13. So I guess the answer would be A. one solution

For each sequence,find the first 4 terms and the 10th term<br> a) n+5<br> b)2n-1
dsp73

Answer:

a)6,7,8,9 and 10th term is 15.

b)1,3,5,7 and 10th term is 19.

Step-by-step explanation:

Given a) n+5

b)2n-1

Solution for  a) n+5

Taking the value of n is 1 we get the first term of the sequence;

n+5=1+5=6

Similarly taking the value of n 2,3,4 we get;

2+5=7\\3+5=8\\4+5=9

And for 10th term we take the value of n is 10 and get;

n+5=10+5=15

So the solution for 1st sequence is 6,7,8,9 and 10th term is 15.

Solution for  b)2n-1

Taking the value of n is 1 we get the first term of the sequence;

2n-1=2\times1-1=2-1=1

Similarly taking the value of n 2,3,4 we get;

2n-1=2\times2-1=4-1=3\\2\times3-1=6-1=5\\2\times4-1=8-1=7

And for 10th term we take the value of n is 10 and get;

2n-1=2\times10-1=20-1=19

So the solution for 2nd sequence is 1,3,5,7 and 10th term is 19.

Solve the system of equations. Show your work.<br> y = x^2 -3x +4 <br> x + y = 4
sesenic [268]

Answer:

x + y = 2 ,  y = x 2 − 4 x + 4

Replace all occurrences of  

y

with  x 2 − 4 x + 4

in each equation.

x 2 − 3 x + 4 = 2 y = x 2 − 4 x + 4

Solve for  

x

in the first equation.

x = 2 , 1 y = x 2 − 4 x+ 4

Replace all occurrences of  

x  with  2

in each equation.

y=0 x = 2

Replace all occurrences of  x

with  1

in each equation.

y = 1 x = 1

The solution to the system is the complete set of ordered pairs that are valid solutions.

( 2 , 0 ) ( 1 , 1 )

The result can be shown in multiple forms.

Point Form:

( 2 , 0 ) , ( 1 , 1 )

Equation Form:

x=2 , y = 0 x = 1 , y = 1

The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet. Cameron determines the area of the wall to
arlik [135]
Area for a rectangle is height * width. Therefore, the area of the wall would be 16.5 * 8.625 = 142.3125. Thus, Cameron's answer is not reasonable since the decimal place is in the wrong place.
