first let's name a couples of variable
• the number of adults tickets sold: a
• the number of children tickets sold: c
From the problem we know
a + c = 128
and
$5.40c + $9.20a = $976.20
1) solve the equation to alpha
a+c-c = 128 -c
a+0=128-c
a=128-c
2) substitute (128 - c) for a in the second equation and solve to c
$5.40c + $9.20a = $976.20 become
$5.40c + $9.20(128 - c) = $976.20
$5.40c + ($9.20 × 128) - ($9.20 - c) = $976.20
$5.40c - $9.20c + $ 1177.6 = $976.20
($5.40 - $9.20)c +$1177.6 = $976.20
-$3.80c + $1177.6 = $9.76.20
-$3.80c + $1177.60 - $1177.60 = $976.20 - $1177.60
-$8.30c + 0 = $201.40
-$3.80c = - $201.40
-$3.80c. -$201.40
________. = _________
-$3.80. -$3.80
-$3.80c. -$201.40
________. = _________. - they are 4 cut the no
-$3.80. -$3.80
c = $201.40
________
3.80
c = 53
Answer:x = 4.666666667 + -0.6666666667y i think
Step-by-step explanation:
Answer:
C. 2
Step-by-step explanation:
222 + 22 + 2 = 246
So A = 2
(x + 4) (x +4) can be your answer
hope this helps
that will equal x²+ 8x + 16
Answer:
Step-by-step explanation:
If we plot both the vertex and the directrix, we see that the parabola opens to the right. We know this because of the fact that the directrix is a vertical line. Because the vertex is to the right of the directrix and a parabola always opens away from the directrix, we know this is of the form
h and k are the coordinates of the vertex which we are given. Our h = 10 and our k = 0. P is defined as the distance between the vertex and the directrix, so our p = 2. Filling in the equation with all of that gives us
and
and
so
Not sure what form you need it in, work form or standard form.
