Answer:
1) x = 17, line a parallel to line b
2) x = 18, line a parallel to line b
Step-by-step explanation:
If line a parallel to line b then (10x - 40) + 50 = 180
Solve for x
10x - 40 + 50 = 180
Combine like terms
10x + 10 = 180
10x = 170
x = 17
x = 17, line a parallel to line b
-------------------------------------------------
If line a parallel to line b then 5x - 16 = 74
Solve for x
5x - 16 = 74
5x = 90
x = 18
x = 18, line a parallel to line b
Answer:
Second graph only.
Step-by-step explanation:
The standard equation of a parabola is ax^2+bx+c where a,b and c are coefficients.
If the coefficient of (a) is positive then the parabola is concave upwards (as in picture 1)
If the coefficient of (a) is negative then the parabola is concave downwards as in picture 2.
Points? couldn't really find anything else if it was a multiple choice question could u share the answers and maybe i can help then
Answer:
y = -x/3 + 5/3
Step-by-step explanation:
In order to find the inverse of a function, you have to switch the x and y values, and then solve for y again.
f(x)=-3x+5
y = -3x + 5
x = -3y + 5
x + 3y = 5
3y = 5 - x
3y = -x + 5
y = -x/3 + 5/3
1980mg(g/1000mg)=1.98g
2g-1.98g=0.02g or 20mg is the difference between the two weights.
