Answer:
119-50 pounds = 69 so 169 pounds -step explanation: blood= weight (k)
Step-by-step explanation:
y=kx
2
4.6 = 170k
finding the constant of variation
3
k= 0.02875
4
equation relates quarts of blood to weight
5
RESULT
4.6 = 170k
y= 0.02875x
y= 0.02875(175)= 5.03125
Answer:
Step-by-step explanation:
Not 3-3 (which is subtraction), but 3^3 (which involves exponentiation.
3^3 = 27
Also: 2^3 = 8; 5^3 = 125
You will see lots of exponentiation in math; please practice and ask questions about it if you have any doubts.
Answer:
2x+y+1=0
Step-by-step explanation:
this is a first degree equation with two unknown variables, x and y. they are referred to as linear equation and are typically represented in slope intercepts form, y=mx+b, where m is the slope of the line and b is the y intercept. So you want to set the equation equal to y by isolating it to one side of the equation.
Subtract all term other than y (in this case, 2x and 1) from both sides of the equation.
2x+y+1-2x-1=0-2x-1
y=-2x-1
