Answer:
y = -x - 6
Step-by-step explanation:
If it's parallel, then it means that the slope will remain the same. The slope is
-1.
To find the y-intercept, you need to plug the coordinates into the equation,
y = -1x + b
-3 = -1(-3) + b
-3 = 3 +b
-6 = b
The equation is y = -x - 6

Answer:
[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]
Step-by-step explanation:
Since the hyperbola opens left and right with a center at the origin, then
[tex]\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1[/tex]
In the graph a = 60 and b = 11
So
[tex]\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1[/tex].
[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]
Mary McDonald makes mugs in Miami. She makes two sizes of mugs: a small mug that she sells for
$2.50 and a large mug that she sells for $5.75. Yesterday Mary made $56. Before she opened her shop in the morning, she had 200 mugs in her inventory. At the end of the day she has 188. How many mugs of
each price did she sell?
Answer:
4 small
8 large
Step-by-step explanation:
s - small mug
l - large mug
Yesterday she had 200 at start of day
at end of day 188 left, so she sold 12 mugs
(1) s + l = 12
(2) 2.50s + 5.75l = 56.00
Solve for l in (1)
l = 12 - s
substitute in l = 12 - s into (2)
2.50s + 5.75(12-s) = 56.00
2.50s + 69.00 - 5.75s = 56.00
-3.25s + 69.00 = 56.00
-3.25s = -13.00
s = 4
to find l substitute s = 4 into (1)
4 + l = 12
l = 8

Mrs. Ortiz measured the outside temperature at noon as -2°F. Later that
day, she measured the temperature as -5°F. Write an inequality that
correctly compares -2 and -5. Then explain the meaning of the inequality
for the situation. 6.NS.7, 6.NS.7b
Answer:
-2°F>-5°F
Step-by-step explanation:
-2°F is greater than -5°F
This also means the first time Mrs. Ortiz measured the outside tempurature it was hotter than the second time she measured it.

Find the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of pi
Answer:
18π cm²
Step-by-step explanation:
The area of the shaded region = Area of Sector
Radius, r =
The value of θ = 80°
Recall :
Area of Sector :
A = θ / 360 * πr²
A = (80 / 360) * π * 9²
A = 0.222222 * π * 81
A = 18π cm²

()) There are two cubes. The first cube has a volume of 1,000 cubic units. The second cube is smaller than the first, with sides only half as long. What is the volume of the second cube? D) cubic units Submit
Answer:
125 units^3
Step-by-step explanation:
Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.
You then divide the sides by 2 because the question says the second cubes sides are half the size
5*5*5 = 125
The volume of the second cube is 125 units³.
What is volume?In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.
We need to find the volume of the second cube,
So, let the side of the first cube be x,
We know that the volume of a cube = side³
Therefore,
x³ = 1000
x = ∛1000
x = 10 units
Therefore, the second cube will have a side of 10/2 = 5 units
Volume of second cube = 5³ = 125 units³.
Hence the volume of the second cube is 125 units³.

Answer:
[tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]
Step-by-step explanation:
Plug in given values of a, b, and c into the quadratic formula and solve for x:
[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
[tex]x=\frac{-8±\sqrt{8^{2}-4(-1)(-14) } }{2(-1)}[/tex]
[tex]x=\frac{-8±\sqrt{64-56 } }{-2}[/tex]
[tex]x=\frac{-8±\sqrt{8} }{-2}[/tex]

Paolo keeps track of his favorite baseball player's batting average, and notices the average is 0.4727272.... If his player has 55 at bats, what is the number of hits?
Answer:
No of hits = 26
Step-by-step explanation:
Given that,
Batting average = 0.4727272
His player has 55 at bats.
We need to find the number of hits. Let the number of hits be x. Using formula for average as :
[tex]\dfrac{x}{55}=0.4727272\\\\x=0.4727272\times 55\\\\x=25.99\\\\or\\\\x=26[/tex]
So, there are 26 number of hits.

find the vertex form of 4x^2+8x-8
Answer:
4(x + 1)^2 - 12.
Step-by-step explanation:
f(x) = 4x^2 + 8x - 8
f(x) = 4(x^2 + 2x) - 8
f(x) = 4[(x + 1)^2 - 1) - 8
f(x) = 4(x + 1)^2 - 4 - 8
f(x) = 4(x + 1)^2 - 12.
If there are 19 questions and each question has 4 answers, what is the probability she will answer at least one question correctly?
Answer:
0.9958
Step-by-step explanation:
P(being correct) = 1/4 = 0.25
Hence, p = 0.25
n = 19
P(x ≥ 1) = p(x = 1) + p(x = 2) +... + p(x = 19)
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
However, to save computation time, we could use a calculator :
Using a calculator,
P(x ≥ 1) = 0.99577
P(x ≥ 1) = 0.9958
