Well he started off right by solving for y=y to find the abscissa of the intersection points between the two points,but then he assumed that their ordinate (y coordinates) are both zero,which is incorrect obviously. To find their ordinate,all we have to do is plug the x values into any of the two equations, since they both will pass through that point ੴ

$y = 4 x+ 1 \\ y = 4(3) + 1 \\ y = 12 + 1 \\ y = 13$

$y = 4x + 1 \\ y = 4( - 2) + 1 \\ y = - 8 + 1 \\ y = - 7$

I chose to plug the values in the second linear equation, since it's easier to compute

Answer:

Step-by-step explanation:

Bill=3475

Interest=1.5%

Total payment made=3475+3475x1.5/100

=3475x101.5/100

=3527.125$ is the total payment (answer)

How do you write 125% as a fraction mixed number or whole number

Alex_Xolod [135]

Answer: Below

Step-by-step explanation:

125% is essentially 1.25 or 125/100.

In mixed number form it's:

Sherman has two sequences . The first sequence is described by the explicit rule f(n) = 15n + 4 and the second sequence is descr

Viktor [21]

Answer:

Step-by-step explanation:

Given the explicit function as

f(n) = 15n+4

The first term of the sequence is at when n= 1

f(1) = 15(1)+4

f(1) = 19

a = 19

Common difference d = f(2)-f(1)

f(2) = 15(2)+4

f(2) = 34

d = 34-19

d = 15

Sum of nth term of an AP = n/2{2a+(n-1)d}

S20 = 20/2{2(19)+(20-1)15)

S20 = 10(38+19(15))

S20 = 10(38+285)

S20 = 10(323)

S20 = 3230.

Sum of the 20th term is 3230

For the explicit function

f(n) = 4n+15

f(1) = 4(1)+15

f(1) = 19

a = 19

Common difference d = f(2)-f(1)

f(2) = 4(2)+15

f(2) = 23

d = 23-19

d = 4

Sum of nth term of an AP = n/2{2a+(n-1)d}

S20 = 20/2{2(19)+(20-1)4)

S20 = 10(38+19(4))

S20 = 10(38+76)

S20 = 10(114)

S20 = 1140

Sum of the 20th terms is 1140
