The x-intercept of the graph is (4 , 0)
Step-by-step explanation:
Let us revise the meaning of x-intercept and y-intercept
- x-intercept means value x when y = 0
- That means the graph intersects x-axis at point (a , 0), where a the value of x when y = 0
- y-intercept means value of y when x = 0
- That means the graph intersects y-axis at point (0 , b), where b is the value of y when x = 0
∵ 5x - 4y = 20 is the equation of the graph
- To find x-intercept substitute y by 0
∵ y = 0
∴ 5x - 4(0) = 20
∴ 5x - 0 = 20
∴ 5x = 20
- Divide both sides by 5
∴ x = 4
The x-intercept of the graph is (4 , 0)

Answer:
I think it is 26 and 2
Step-by-step explanation:
39÷6=6.5
4×6.5=26
13÷6.5=2
Homework = 12.5% of 24 hours = 0.125 x 24 = 3 hours
Sam spent <u>3 hours</u> on homework.
Proportion of the time spent on homework = 3/24 = 1/8
Answer: Same spent 1/8 of his day on homework.
Answer:
oof im only in 9th lol i should know this
Step-by-step explanation:
Let x= original savings
(x-1,600) - 2/5 (x-1,600) = 1/3x
(x-1,600) - 2/5 + 640 = 1/3x
(3/5)x - 960 = 1/3x
(3/5)x - (1/3)x = 960
(4/15)x = 960
(15/4)(4/15)x = (15/4) 960
x = 15* 240 (960/4 = 240)
x = $3,600 is his original savings
Check:
$3,600 - 1,600 = 2,000
(2/5)($2,000) = $800
2,000 - 800 = 1,200 left over
