The region represented by the inequality in vertex form is the inequality in the last option y ≥ -(x - 50)² + 625.
What is a quadratic inequality?An inequality with a quadratic expression is referred to as a quadratic inequality.It is of the form y > ax² + bx + c (or substitute <,≥ or ≤ for > ) represents a region of the plane that a parabola encircles.Let's assume that the equation is y = a(x - h)² + k
y = a(x - 50)² + 625
Put the point (61,504) in the equation
⇒ 504 = a(61 - 50)² + 625
⇒ 504 = a(11)² + 625
⇒ 504 = 121a + 625
⇒ 121a = -625 + 504
⇒ 121a = -121
⇒ a = -1
y = -(x - 50)² + 625
Hence the inequality is y ≥ -(x - 50)² + 625.

the function f multiplies it’s input by 2 and then subtracts 17 to produce its output. What is the symbolic representation of this operation
Answers
Answer:
f(x)= 2x-17
Step-by-step explanation:
Let, input be x,
Multiplying input by 2: 2x
then subtracting it by 17: 2x-17
Therefore, Symbolic representation required is : f(x)= 2x-17
The symbolic representation of the function defined is f(x) = 2x-17
What is function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given that, the function f multiplies it’s input by 2 and then subtracts 17 to produce its output. we need to express the operation into symbolic representation.
Let the input be x, then the output will be the value of f(x).
Therefore, it is given, the input is multiplied by 2, that mean,
f(x) = 2x
Then 17 is subtracted from it, that will give,
f(x) = 2x-17
Hence, the symbolic representation of the given operation is f(x) = 2x-17

Step-by-step explanation:
remember, a parallelogram is a quadrilateral with 2 pairs of parallel and equal sides, and 2 pairs of correspondingly equal angles. and its diagonals are intersecting each other in their midpoint.
with that in mind
(i)
because ABCD is a parallelogram, AD = BC, and AB = CD.
and angle A = angle C (and angle B = angle D).
therefore, as AE = FC, this also means that ED = BF.
via SAS (side angle side) it is clear that the triangles ABE and CDF are congruent.
therefore, EB = DF.
as ED is part of AD, and BF is part of BC, it is also clear that ED || BF.
together with ED = BF this means that EB || DF.
so, we have with BEDF 2 pairs of parallel and equal sides. and that is a parallelogram.
(j)
BCDE and ABCG are parallelograms.
so, BC = DE = AG, CD = BE, AB = CG.
due to the midpoint intersection rule of the diagonals of parallelograms, we also know
GE = CG = AB, DG = BG.
and as CG || AB, then also GE || AB.
together with AB = GE that means that AE = BG and AE || BG.
so, we have with ABGE again 2 pairs of parallel and equal sides. and that is a parallelogram.

Standard form of a quadratic equation:

Question 1
Given:
[tex]x^2+x=20[/tex]
Rearrange to standard form by subtracting 20 from both sides:
[tex]\implies x^2+x -20=20-20[/tex]
[tex]\implies x^2+x -20=0[/tex]
Therefore:
a = 1b = 1c = -20Question 2
Given:
[tex]4x^2-2x=28[/tex]
Rearrange to standard form by subtracting 28 from both sides:
[tex]\implies 4x^2-2x-28=28-28[/tex]
[tex]\implies 4x^2-2x-28=0[/tex]
Therefore:
a = 4b = -2c = -28Question 3
Given:
[tex]5x^2=225[/tex]
Rearrange to standard form by subtracting 225 from both sides:
[tex]\implies 5x^2-225=225-225[/tex]
[tex]\implies 5x^2-225=0[/tex]
Therefore:
a = 5b = 0c = -225Question 4
Given:
[tex]x^2-x=36[/tex]
Rearrange to standard form by subtracting 36 from both sides:
[tex]\implies x^2-x-36=36-36[/tex]
[tex]\implies x^2-x-36=0[/tex]
Therefore:
a = 1b = -1c = -36Question 5
Given:
[tex]3x^2-4=7x[/tex]
Rearrange to standard form by subtracting 7x from both sides:
[tex]\implies 3x^2-4-7x=7x-7x[/tex]

A total of 491 tickets were sold for the school play. They were either adult tickets or student tickets. There
were 60 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answers
Answer:
Adult tickets = 276
Step-by-step explanation:
a + s = 491 Eq. 1
a = s + 61 Eq. 2
a = adult tickets
s = student ticket
Replacing Eq. 2 in Eq. 1:
(s+61) + s = 491
2s + 61 = 491
2s = 491 - 61
2s = 430
s = 430/2
s = 215
from the Eq. 2
a = s + 61
a = 215 + 61
a = 276
Check:
from Eq. 1:
a + s = 491
276 + 215 = 491

Layla has $680 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $319.28.
She buys 3 bicycle reflectors for $4.90 each and a pair of bike gloves for $37.94.
She plans to spend some or all of the money she has left to buy new biking outfits for $77.02 each.
Use the drop-down menu below to write an inequality representing oo, the number of outfits she can buy while staying within her budget.
Answers
Layla should by not more than 4 outfits in order not to exceed her budget
The inequality expression is n ≤ 4
Given data
price of a new bicycles = $319.28
3 bicycle reflectors = $4.90
a pair of bike gloves = $37.94.
new biking outfits = $77.02 each
Layla's total money to spend at a bicycle store = $680
How to write the required inequality equationLayla's expenses will not be more than her total amount to spend at the bicycle store therefore will use less than or equal to sign, before the sum of the other items
The expression is written as follows
$680 ≤ $319.28 + 3 * $4.90 + $37.94 + n * $77.02
where n represents the number of the new biking outfits
$680 - ( $319.28 + 3 * $4.90 + $37.94 ) ≤. + n * $77.02
( $680 - ( $319.28 + 3 * $4.90 + $37.94 ) ) / $77.02 ≥ n
( $680 - $371.64 ) / $77.02 ≥ n
( $308.36) / $77.02 ≥ n
4 ≥ n

Answers
The sum of the ball's kinetic energy and potential energy remains the same. as the ball rolls from point A to E.( if there is no friction between the ball and the ground).
based on the law of mechanical energy's conservation, the sum of both kinetic and potential energies i.e. the total amount of mechanical energy remain conserved even in the absence of dissipative forces ( friction or air resistance) in a bound system.
the kinetic energy is when ball goes downward but potential energy decreases and reverse happens when ball goes up. but in these case, the sum energy would be constant one.
The ball would not change the energy.

because BCDF is a parallelogram, it means that F D = B C = 4.
and F B = D C = 6.
because EDCF is a parallelogram, it means that D C = E F = 6.
that means that E F = F B = 6, so the diagonal E B of ABDE is intersected by the other diagonal A D in the middle at F.
because ABCF is a parallelogram, it means that A F = B C = 4.
that means that A F = F D = 4, so, also the diagonal A D of ABDE is intersected by the other diagonal E B in the middle at F.
when 2 line segments E B and A D intersect each other that way, that makes them the diagonals of a parallelogram.
therefore, ABDE is a parallelogram.

The slope of the line for 3-day charity ride is 30.
What is referred as the slope of the straight line?The slope of a straight line indicates the steepness of its inclination. It is also known as the gradient.
The greater the slope of a line, the steeper it is.The slope of a line remains constant throughout its length, ensuring that the line is straight.A line can be thought of as the hypotenuse of such a right-angled triangle.A slope measurement is calculated by comparing its vertical and horizontal components.The formula for the slope is;
slope = m = Δy/Δx
m = (y₂ - y₁)/(x₂ - x₁)
The given coordinators of the points (taken from Jack's graph are);
(x₁, y₁) = (2, 60)
(x₂, y₂) = (3, 90)
Put the values in the formula;
m = (90 - 60)/(3 - 2)
