Answer:
y - 4 = -2/3 (x + 1)
Step-by-step explanation:
y2 - y1 / x2 - x1 -2 - 4 / 8 - (-1) -6/9 = -2/3
y - 4 = -2/3 (x + 1)
Answer:
x = 6
y = - 14
Step-by-step explanation:
- -2x × 2 + 10 = - 2x - 2
- x = 6
- y = -2 × 6 - 2 = - 14
Answer: The answer is 25
Step-by-step explanation:
You multiply 5 times 5 and you get 25 or you could count 5 fingers 5 times
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
Answer:
1.1h+0.75c=4.55---------------1
h+c=5--------------2
Step-by-step explanation:
Step one:
given data
total lunch items= 5
let hot dogs be h
and cookies be c
cost of hot dogs = $1.10
cost of cookies = $0.75
total cost = $4.55
Step two:
The linear model for the total cost is given as
4.55=1.1h+0.75c---------------1
and the model for the number of items is
h+c=5--------------2
The systems of the equation for the situation is
1.1h+0.75c=4.55---------------1
h+c=5--------------2
