Answer:
Martha can buy 7 packs of socks.
Step-by-step explanation:
Martha has $53
Shoes = $42
Socks = $1.50 each
First subtract 42 from 53 to figure out how much is left:
⇒ $53 - $42 = $11
then divide the answer by how much each pack of socks cost:
⇒
= 7.33
next, take the whole number of the answer and multiply that by $1.50 to figure how much 7 pack of socks cost:
⇒ 7 socks x $1.50 = $10.50
subtract the answer from $11 to figure out how much remains:
⇒ $11 - $10.5 = $0.50
Answer:
120
Step-by-step explanation:
370m - (65 x 2) = 240
240 divided by 2 = 120
(4x³ + 9xy + 8y) - (3x³ + 5xy - 8y) =
= 4x³ + 9xy + 8y - 3x³ - 5xy + 8y =
= 4x³ - 3x³ + 9xy - 5xy + 8y + 8y =
= x³ + 4xy + 16y ← the end answer
<u>Vertex</u>
y = -(x + 3)² + 1
y = -(x + 3)(x + 3) + 1
y = -(x² + 3x + 3x + 9) + 1
y = -(x² + 6x + 9) + 1
y = -x² - 6x - 9 + 1
y = -x² - 6x - 8
-x² - 6x - 8 = 0
x = <u>-(-6) +/- √((-6)² - 4(-1)(-8))</u>
2(-1)
x = <u>6 +/- √(36 - 32)</u>
-2
x = <u>6 +/- √(4)
</u> -2<u>
</u>x = <u>6 +/- 2
</u> -2
x = <u>6 + 2</u> x = <u>6 - 2</u>
-2 -2
x = <u>8</u> x = <u>4</u>
-2 -2
x = -4 x = -2
y = -x² - 6x - 8
y = -(-4)² - 6(-4) - 8
y = -(16) + 24 - 8
y = -16 + 24 - 8
y = 8 - 8
y = 0
(x, y) = (-4, 0)
or
y = -x² - 6x - 8
y = -(-2)² - 6(-2) - 8
y = -(4) + 12 - 8
y = -4 + 12 - 8
y = 8 - 8
y = 0
(x, y) = (-2, 0)

The axis of symmetry is equal to -3.
