the graph of y=x^2-4x is shown. name a zero of the function below

Answers

Answer 1

Answer:

0 and 4

Step-by-step explanation:

y = x^2 - 4x can be factored as follows:  y = x(x - 4).

We find the zeros by setting this factored form equal to zero and solving for x:

x(x - 4) = 0, or x = 0, or x = 4.

The two zeros of this function are 0 and 4.

If x=8 and y=−4, evaluate the following expression:
20-5y+2x​

Answers

Answer:

the answer will be: 16

Step-by-step explanation:

Why? Because =

20-5y+2x

20 - 5 • 4 + 2 • 8 =

(5 • 4 = 20)

(2 • 8 = 16)

20 - 20 + 16 =

(20 + 16 = 36)

20 - 36 = 16

Area = 120

Step-by-step explanation:

Triangle formula:

[tex]\frac{1}{2}[/tex](b x h)

Given:

[tex]\frac{1}{2}[/tex](10 x 24)

Multiply 10 and 24 to get 240.

10 x 24 = 240

Divide 240 and 2 to get 120.

240 ÷ 2 = 120

So answer is 120.

Two trapeziums are similar, thee area of one of the trapezium is 4times that of the other. Determine the ratio of the perimeter & the corresponding side length of the trapezium​

Answers

Answer:

The ratio of the perimeters of the two trapezium is 2

The ratio of the corresponding sides of the two trapezium is 2

Step-by-step explanation:

The given parameters in the question are;

Two trapeziums are similar

The area of one trapezium = 4 × The area of the other trapezium

Let, A₁, and A₂ represent the area of the two trapeziums, we have

A₁ = 4 × A₂

∴ A₁/A₂ = 4

Given that ratio of areas = (Ratio of sides)²

Ratio of sides = Ratio of perimeter

∴ Ratio of areas = (Ratio of perimeter)²

Therefore, given that the ratio of the areas of the two trapeziums A₁/A₂ = 4, we have;

Ratio of areas = 4 = (Ratio of sides)²

The ratio of the corresponding sides = √4 = 2

The ratio of the corresponding sides = 2

Ratio of areas = 4 = (Ratio of perimeter)²

The ratio of the perimeter = √4 = 2

The ratio of the perimeter = 2

Answer:

The ratio of the perimeters of the two trapezium is 2

The ratio of the corresponding sides of the two trapezium is 2

Step-by-step explanation:

The given parameters in the question are;

Two trapeziums are similar

The area of one trapezium = 4 × The area of the other trapezium

Let, A₁, and A₂ represent the area of the two trapeziums, we have

A₁ = 4 × A₂

∴ A₁/A₂ = 4

Given that ratio of areas = (Ratio of sides)²

Ratio of sides = Ratio of perimeter

∴ Ratio of areas = (Ratio of perimeter)²

Therefore, given that the ratio of the areas of the two trapeziums A₁/A₂ = 4, we have;

Ratio of areas = 4 = (Ratio of sides)²

The ratio of the corresponding sides = √4 = 2

The ratio of the corresponding sides = 2

Ratio of areas = 4 = (Ratio of perimeter)²

The ratio of the perimeter = √4 = 2

The ratio of the perimeter = 2

Second step: simplify 15x < 12 + y

Third Step: This you got to divide both sides by 15 like this: 15x/15 < 12/15 + y/15

Last and Fourth step:  Simplify and thats your answer  x < 12 + y/15

show that triangle BCD is isosceles

Answers

∠A = 36
∠C =36
∠ADB =72°
∠CBD =36°
∠BDC =108°

Explanation:

AB=AD then ∠ABD & ∠ADB must be equal as they share two lines that are equal so ∠ADB=72°

∠A and ∠C must also be equal (AB=BC)
∠A = 180-72-72=36°
So ∠A & ∠C=36°

∠D=180° (straight line)
So if ∠ADC=72
∠BDC=108° (180-72)

A triangle has 180° so in triangle BDC we have 108° and 36°
So remaining angle (∠CBD) =180-108-36
=36°

This tells us that triangle BDC is isosceles as it has two equal angles ∠CBD & ∠C =36°

Step-by-step explanation:

∠BAC = ∠BCA because it is an isosceles triangle

∠ADB = ∠ABD = 72° because it is an isosceles triangle

∠BAD = 180° - 72° - 72° = 36° because the sum of all interior angles in a triangle = 180°

∠BDC = 180° - 72° = 108° because it is supplementary to 72°

∠ABC = 180° - 36° - 36° = 108° because the sum of all interior angles in a triangle = 180°

∠DBC = 108° - 72° = 36°  (∠ABC - ∠ABD)

since ∠DBC = ∠DCB, ΔBCD is isosceles

Find the output, y, when the input, x, is 30
y=14 - 0.5x

Answers

Answer:

y = -1

Step-by-step explanation:

Given x = 30 , y = 14 -0.5x

Find y

let (x = 30) fill in y

y = 14 - 0.5(30)

y = 14 - 15

Thus , y = -1

Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda. Carla collects 3(5 + 2f) bottles. How many bottles did they collect altogether in terms of f ?

Answers

Answer:

18f - 6 bottles

Step-by-step explanation:

Amanda, Bruno and Carla collected bottle caps for charity. Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda. Carla collects 3(5 + 2f) bottles. How many bottles did they collect altogether in terms of f ?

From the question

Amanda collected (4f – 3) bottle caps. Bruno collects twice as many bottle caps as Amanda.

= 2(4f - 3)

= 8f - 6 bottle caps

Carla collects 3(5 + 2f) bottles.

= 15 + 6f bottles

The number of bottles they collected altogether in terms of f is calculated as:

(4f – 3) bottle + 8f - 6 bottle + 15 + 6f bottle

4f - 3 + 8f - 6 + 15 + 6f

= 18f - 6
