Answer:
with what?
Step-by-step explanation:
there's nothing there? srry?
Step-by-step explanation:
Make a table to find the values of x
P.s pick random y value
When x is 1,
y is 4........ Plug 1 into the equation ur given u get the value of y. So, 2(1)+2
When x is 2,
y is 6......... Plug 2 into the equation ur given u get the value of y. So, 2(2)+2
So this point is (2,6)
When x is 3
y is 8 ......2(3)+2
So this point is (3,8)
When x is 4
y is 10.... 2(10)+2
So this point is (4,10)
Hope this helps
Answer:
102 gallons of 55% antifreeze
68 gallons of 80% antifreeze
Step-by-step explanation:
55% antifreeze: x
80% antifreeze: y
x + y = 170 ===> -.55(x + y = 170) ===> -.55x - .55y = -93.5
.55x + .80y = .65(170) ===> .55x + .80y = 110.5
________________
add the two equations to eliminate a variable: 0.25y = 17
divide by 0.25 to isolate y: y = 68
substitution to find x:
x + y = 170
x + 68 = 170
x = 102
Answer: -5x+6
Step-by-step explanation:
Find slope through slope formula (y₂-y₁)/(x₂-x₁)
- By doing this you find that the slope is -5
Then the y-intercept is found through the intersection of the y-axis.
