Why do people say if you answer a question that they thank is really hard they say they will give you a brainiest?

Answer:

Point A

Step-by-step explanation:

The long that would be used to find f(3) is the point that shows the value of y when x = 3.

Looking at the graph given, the only point that shows the value of y when x = 3 is point A.

When x = 3, y = 0.

Therefore, f(3) = 0.

Answer:

y = 1.5x

Step-by-step explanation:

Charge for 3 pounds of salad is $4.50

Charge per pound is thus 4.5/3 = $1.5

Now, we want to write an equation that can be used to represent the cost of salad y for x pounds of salad

Mathematically, that will be;

y = 1.5x

Answer:

p(-2) = -11

p(0) = -3

p(5) = 17

Step-by-step explanation:

Think of p(x) as a y.  Just substitute the x values into the equation, and with some basic algebra, you should get your answer

p(-2) = -3 + (-8) = -11

p(0) = -3 + 0 = -3

p(5) = -3 + 20 = 17

Step-by-step explanation:

The approximate stopping distance d(in feet) is given by the formula :

[tex]d=0.05v^2+2.2v[/tex] ...(1)

Where

v is the speed of the car in mph

We need to find the speed of the car when the distance is 200 feet

Put d = 200 in equation (1)

[tex]0.05v^2+2.2v=200\\\\0.05v^2+2.2v-200=0[/tex]

It is a quadratic equation. Divide the above equation by 0.05.

[tex]v^2+44v-4000=0[/tex]

The solution of the above equation is given by :

[tex]v=\dfrac{-44\pm \sqrt{44^2- 4(1)(-4000)} }{2(1)}\\\\v=\dfrac{-44+ \sqrt{44^2- 4(1)(-4000)} }{2(1)},\dfrac{-44- \sqrt{44^2- 4(1)(-4000)} }{2(1)}\\\\v=44.96\ ft/h, -88.96\ ft/h[/tex]

Since, 1 mph = 5280 ft/hour

44.96 ft/h = 0.00851 mph

-88.96 = -0.0168 mph

Hence, this is the required siolution.

Step-by-step explanation:

Answer:

Not sure what exactly you're asking here but if you want to solve for Y, you add 5 to both sides. The answer for that is Y > 17.

Step-by-step explanation:

Answer:

0.267

Step-by-step explanation:

the two shapes are similar but scaled differently

this ratio is 2:3 (EF:AB)

so to find y we’ll set this up

2/3= y/4.5

and solve for y

4.5(2/3) = y

y = 9/3

y = 3

Answer:

ΔABC has: AD=DB

                  AE = EC

=> DE is the median line of ΔABC

=> DE // BC

=> m∠AED = m∠ECF = 32°

.

Step-by-step explanation:

Answer:

∠ ECF = 32°

Step-by-step explanation:

DE is the midsegment of Δ ABC and is therefore parallel to the third side BC.

Since DE and BC are parallel lines, then

∠ ECF and ∠ AED are congruent ( corresponding angles ) , thus

∠ ECF = ∠ AED = 32°

Answer:

The cost for adult tickets be represented by x = $5

The cost for student tickets be y = $2

Step-by-step explanation:

Let the cost for adult tickets be represented by x

the cost for student tickets be y

The Montague family and their neighbors the Capulets attended the school play together. The Montagues bought two adult tickets and three student tickets for $16.

= 2x + 3y = 16... Equation 1

The Capulets purchased three adult tickets and two student tickets for $19.

3x + 2y = 19 ..... Equation 2

How much was each adult and student ticket?

2x + 3y = 16... Equation 1

3x + 2y = 19 ..... Equation 2

We solve using Elimination method

Multiply Equation 1 by 2 and Equation 2 by 3 to eliminate u

4x + 6y = 32..... Equation 3

9x + 6y = 57.... Equation 4

Subtract Equation 4 from 3

-5x = -25

x = 25/5

x = $5

2x + 3y = 16... Equation 1

Since x = $5

2($5) + 3y = 16

10 + 3y = 16

3y = 16 - 10

3y = 6

y = 6/3

y = $2

Therefore:

The cost for adult tickets be represented by x = $5

The cost for student tickets be y = $2

Answer:

Section A = 26,500 seats

Section B = 14,900 seats

Section C = 11,600 seats

Step-by-step explanation:

Total seats = 53,000

Total revenue = 1,997,400

Section A seat = $42

Section B seat = $36

Section C seat = $30

The number of seats in this in section A equals the total number of seats in section BNC

A = B + C

A + B + C = 53,000 (1)

42A + 36B + 30C = 1,997,400 (2)

Substitute A = B + C into (1)

A + B + C = 53,000

B + C + B + C = 53,000

2B + 2C = 53,000

2(B + C ) = 53,000

B + C = 53,000 / 2

= 26,500

B + C = 26,500 (3)

Substitute B + C = 26,500 into (2)

42A + 36B + 30C = 1,997,400

Recall,

A = B + C

42( 26,500) + 36B + 30C = 1,997,400

1,113,000 + 36B + 30C = 1,997,400

36B + 30C = 1,997,400 - 1,113,000

36B + 30C = 884,400. (4)

Multiply (3) by 30

B + C = 26,500 × 30

30B + 30C = 795,000 (5)

36B + 30C = 884,400 (4)

Subtract (5) from (4) to eliminate C

36B - 30B = 884,400 - 795,000

6B = 89,400

B = 89,400/6

= 14,900

B = 14,900

From (3)

B + C = 26,500

C = 26,500 - B

= 26,500 - 14,900

= 11,600

A = B + C

= 14,900 + 11,600

= 26,500

Section A = 26,500 seats

Section B = 14,900 seats

Section C = 11,600 seats

We will use the following

y for the number of bacteria at a given time

x for the time

a for the starting number of bacteria, which is 700

b for the base of the exponent

so lets find b, we need the following:

Answer:

98

Step-by-step explanation:

Mathematically, when we add all the angles of a triangle, we get 180

Thus;

x + 1 + 2x-2+ 3x-5 = 180

6x-6 = 180

6x = 186

x = 186/6

x = 31

so the measure of the biggest angle is 3x -5

= 3(31) + 5 = 93 + 5 = 98

Answer:

The other sides are called legs.

Step-by-step explanation:

Right Triangles

They are a special type of triangles on which one of its internal angles is 90°. Since the sum of all internal angles is 180°, the sum of the other acute angles is 90°.

The longest side is called the hypotenuse and the other two sides are called legs.

The attached image shows a right triangle of hypotenuse c and legs a and b.
