What is the x-intercept of y=5x+20?
densk [106]

Answer:

the x intercept is -4

Step-by-step explanation:

to find the x intercept, set y = 0 and solve for x

y = 5x+20

0 = 5x+20

subtract 20 from each side

-20 = 5x +20 -20

-20 = 5x

divide each side by 5

-20/5 = 5x/5

-4 =x

shusha [124]

Answer:

$478

Step-by-step explanation:

After 20 years, William will have a total of $3,513.94

After 20 years, Nolan will have a total of $3,991.93

Difference = $478

William:

2300[1 + (.02125 ÷ 4)]^4 · 20

2300 · (1 + .0053125)^80

2300(1.5278)

$3,513.94

Nolan:

2300[1 + (.0275 ÷ 12)]^12 · 20

2300 · (1 + .0023)^240

2300(1.7356)

$3,991.93
