Answer:
2.8 gallons 0.5% milk
4.2 gallons 3% milk
Step-by-step explanation:
let 'x' = .5% milk
let 'y' = 3% milk
System of Equations:
x + y = 7
.005x + .03y = 7(.02)
I used the substitution method and solved the first equation for y: y = 7 - x
.005x + .03(7 - x) = .14
.005x + 0.21 - .03x = 0.14
-0.025x + 0.21 = 0.14
-0.025x = -0.07
x = 2.8
7 - 2.8 = 4.2
y = 4.2
you need to find how much the output changes for each unit change in the input. (ie from an input change from 5 to 6 the output changes by three units and an input change of 3 (2 - 5 ) units the output changes by 9 units). This will give you the gradient of the equation. then you have to find out the y intercept by finding what the output is when the input is 0. Do this by multiplying the input by the gradient and then subtracting it from that inputs output. This will give you the answer A) 3x
(Sorry, its a bit wordy :) )
1-First let’s list the numbers between 210 to 220, except the even ones since they’re a multiple of 2:
211; 213; 215; 217; 219
Let’s remove 213, and 219 because they’re multiples of 3 (2+1+3=6; 2+1+9=12), 215 is multiple of 5, so let’s remove it.
That leave’s is with 211, and 217.
We can remove 217, because it’s a multiple of 7, leaving us with 211.
2- It’s deductive reasoning, because you started with a more general idea.
3- {-7, -6, -5, -4, -3, -2, -1, 0, 1}
4- {x e R, x>=-2}
5-{-1, 0, 1}
6- {x∣-4≤ x ≤6}
7- [-20, ♾ )
8- On a number line, make a circle around -1, and continue the line to minus infinity.
9- On a number line, make a circle on -3, and continue to minus infinity. Make a ring on 0, and continue to infinity.
Answer:
No, the function is not continuous at x=
