Answer:
The y-intercept is the point (0,-4)
Step-by-step explanation:
we know that
The x-intercept is the value of x when the value of y is equal to zero
The y-intercept is the value of y when the value of x is equal to zero
Looking at the graph
The x-intercept is the point (-4,0)
The y-intercept is the point (0,-4)
Answer:
7 and 3 respectively
Step-by-step explanation:
Peanuts (p/lb) = $1.80
Cashews (p/lb) = $4.50
Total pound = 10 pounds
Aggregate amount (at $2.61 per lb) = $26.1
Pound of peanut to buy = x
Pound of cashew to buy = y
x + y = 10..........(i)
1.8x + 4.5y = 26.1.....(ii)
Multiply equ (i) by 1.8 and equ (ii) by 1
1.8x + 1.8y = 18
1.8x + 4.5y = 26.1
Subtract (i) from (ii)
4.5y - 1.8y = 26.1 - 18
2.7y = 8.1
y = 3
Sub y = 3 into (i)
x + y = 10
x + 3 = 10
x = 10 - 3
= 7
Pounds of peanut to buy = 7 pounds
Pounds of cashew to buy = 3 pounds
7:9 because there are 35 children and 10 adults. Add 35 and 10 you get 35:45 then you simplify the ratio to get 7:9.
