In the function v= 4x² – 5, what effect does the number -5 have on the graph, as compared to the graph of the function y = x??
O A. It shifts the graph 5 units to the left.
O B. It shifts the graph up 5 units.
O C. It shifts the graph down 5 units.
O D. It shifts the graph 5 units to the right.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

lol.

it's ok we all do this sometimes.
