We have that
<span>(x+2)(y+3)=0
we know that
Part A)
the x-intercept is when y=0
for y=0
</span>(x+2)(0+3)=0--------> (x+2)*3=0------> 3x+6=0----> 3x=-6----> x=-2
the point is (-2,0)
Part B)
the y-intercep is when x=0
for x=0
(0+2)(y+3)=0-----> 2*(y+3)=0-----> 2y+6=0----> y=-6/2-----> y=-3
the point is (0,-3)
Lets try substitution5x+2y=21=5x=21-2y=x=(21-2y)/5
sub into second equation
-2(21-2y)/5+6y=-34(-42+4y)/5+6y=-34solve for yy=-64/17plug into equation and solve for x=(97/17)
Set y to 0 and solve. 0 = 4( -1/2 ) + 2.
x = -1/2
Answer:
If the discs were measured to the nearest milimetre, it might be possible, that they are actually 1.64cm wide instead of only 1.64cm as shown.
Therefore the box would fill up much quicker and there will not be enough space.
Step-by-step explanation:
1.6cm * 16 discs = 25.6cm (would fit)
1.64cm * 16 discs = 26.24cm (would not fit)
Answer:$9
Step-by-step explanation:Here's what we know:
2 * 24 + 3s = 75 (the pants ($24 each) and shirts all together is $75)
What we need to do is isolate s
Simplify:
48 + 3s = 75
subtract 48 from both sides:
48 + 3s - 48 = 75 - 48
3s = 27
Divide by 3:
3s / 3 = 27 / 3
s = 9
Shirts are $9 each.
