Area = 3x + 24

Area is length • width. If the length is 3 and the other width/length is x+8 you have to multiply the two.

3 • (x+8) = 3x+24
Use the distributive property!

Well I need the help in this last question I will mark brain list if you got it right

Answer:

6x−11y+15

Step-by-step explanation:

Distribute the Negative Sign:

=5x−6y+7+−1(−x+5y−8)

=5x+−6y+7+−1(−x)+−1(5y)+(−1)(−8)

=5x+−6y+7+x+−5y+8

Combine Like Terms:

=5x+−6y+7+x+−5y+8

=(5x+x)+(−6y+−5y)+(7+8)

=6x+−11y+15

Answer:

6x−11y+15

A taxicab charges $1.75 for the flat fee and $0.25 for each mile. write an inequality to determine how many miles eddie can trav

aev [14]

The correct option is a. $1.75 + $0.25x ≤ $15; x < 53 miles.

The inequality that represents given situation is $1.75 + $0.25x ≤ $15.

<h3>What is inequalities?</h3>

An inequality compares the two values to determine if one is less than, larger than, or simply simply equal to the other.

a ≠ b indicates that an is not equal to b.
a < b indicates that an is less than b.
The expression a > b indicates that an is greater than b. (those two are called as strict inequality)
a ≤ b signifies that an is less than or equal to b.
The expression a ≥ b denotes that an is greater than or equal to b.

Now for the given question;

A cab charges $1.75 for the flat fee.

And, the cab charges $0.25 for each mile.

Total amount spent by Eddie is 1$15.

So, first and foremost. Because you have to pay the fixed charge and then pay for x miles is $0.25.

Thus, (15-1.75) / 0.25 = 53.

Therefore, the inequalities which describes the given scenario is;

$1.75 + $0.25x ≤ $15

where, x < 53 miles.

The correct question is-

A cab charges $1.75 for the flat fee and $0.25 for each mile. Write and solve an inequality to determine how many miles Eddie can travel if he has $15 to spend.

a. $1.75 + $0.25x ≤ $15; x ≤ 53 miles

b. $1.75 + $0.25x ≥ $15; x ≥ 53 miles

c. $0.25 + $1.75x ≤ $15; x ≤ 8 miles

d. $0.25 + $1.75x ≥ $15; x ≥ 8 miles

I'LL GIVE BRAINLIST TO THOSE WHO WILL ANSWER IT CORRECT.

EleoNora [17]

Answer:

28 cm²

Step-by-step explanation:

Refer to attached

Let the half/side of the square be a and the difference of the point in the middle be x and y respectively

Each shape is the sum of 2 triangles, which have a base of a

The area to be found is A

We will show the area of each four shapes as:

a(a-x) + a(a-y) = 16*2 ⇒ (1)
a(a-x) + a(a+y) = 20*2 ⇒ (2)
a(a+y) + a(a+x) = 32*2 ⇒ (3)
a(a-y) + a(a+x) = A*2 ⇒ (4)

Now comparing the expressions:

(2) – (1) = a(a + y -a + y) = 2ay = 8 ⇒ ay = 4
(3) – (2) = a(a + x - a + x ) = 2ax = 24 ⇒ ax = 12
(1) + (3) ⇒ 4a² = 96 ⇒ a² = 24

Using the values we got, finding the area A:

(4) ⇒ 2A = 2a^2 - ay + ax = 48 - 4 + 12 = 56
A = 56/2 = 28 cm²

red bird's flight path can be modeled by the quadratic equation y=-x^2+12x-11. What is the vertex? What is the axis of symmetry?

Rasek [7]

Quadratic Equation: $y=-x^2+12x-11$

What is the Vertex?
Vertex Form: $y=a(x - h)^2 + k$ , where (h, k) is the vertex of the parabola.
 $y=-x^2+12x-11$
$y=(-x^2+12x)-11$
$y=-1(x^2-12x)-11$
$y=-1(x^2-12x+36-36)-11$
$y=-1(x^2-12x+36)+36-11$
$y=-1(x-6)^2+25$
Vertex is (6,25)

Axis of Symmetry?
This is just the h value so the AoS = 6

Total Distance? (I assume x-intercepts)
 $y=-x^2+12x-11$
$y=-1(x^2-12x+11)$
$y=-(x-1)(x-11)$
x-intercepts are (1,0) and (11,0) so in between them was the flight.

Domain and Range?
I'm not sure what domain and range are but I found a calc online for it and it says
Domain: (−∞,∞),{x|x∈R}Range: (−∞,25],{y|y≤25}
