Answer:
$327.25
Step-by-step explanation:
so first we apply the $50 discount
$435-$50= $385
then we find how much the 15% discount is worth by turning the percent into a decimal and multiplying by the $385
385•0.15= 57.75
now we subtract the value of the discount from the newer price
385-57.75= $327.25
hope this makes sense <3
For two linear equations to have exactly one solution, their gradient/slope must be different. That's the only requirement. For example y=x intersects with -1/3x - 8 at (-6, -6). So one that has only one solution could be y=x+5.
For two linear equations to have no solutions they must have the same gradient/slope but not be the same equation. Hence, y = -1/3x + 8 would never intersect with y = -1/3x - 8.
For two linear equations to have infinite solutions, they must be the same line or simplify to give the same line. I.e. 3y = -x - 8 would have infinitely many solutions with the above graph.
Yeah youre good because
.80 times 14 is 11.2
Answer:
-2
Step-by-step explanation:
Put the given values of x and y in the equation, and solve for "a".
-40 = a(1 +3)(1 -2)(1 -6) = 20a
-40/20 = a = -2
The value of "a" is -2.
if you have already covered slopes, you could also get it that way, in fact is simpler that way.
