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.

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
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

First step: you got to add y to both sides in the math problem Ex: 15x - y + y < 12 + y
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

A train left for Houston, and 5 hours later, a car traveling 74 mph tried catching up to the train. After
8 hours, the car caught up. What was the train's average speed?
Answer:
45.538 mph
Step-by-step explanation:
v = d/t (velocity = distance/time)
74 mph = d/8
d = 592 miles
[tex]v_{train}=\frac{592 miles}{5+8 hours}[/tex]
= 45.538 mph

Explain how to plot the point (3, -7) on the coordinate plane.
Answer:
Start at the origin to plot the point. The x-coordinate, 3, indicates that you need to move 3 units to the right. The y-coordinate, −7, indicates that you need to move down 7 units. Then plot the point.

show that triangle BCD is isosceles
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
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(3x)²×-3x³ simplify nd give answer in positive exponets

If you want 2 cookies and you only have.50 cents and the cookies cost 10 dollars how much money will you have to get if you only have.50 cents
Answer:
The answer would be 15 cookies.
Step-by-step explanation:
Cookies = 24 cents each
Pop = 45 cents each
you would need about 2000 pennies to have enough to buy two cookies, 2000-50=1950, so if you have 50 cents you would need 1,950 more pennies to be able to get 2 cookies

Dara pinkston Recorded her house and expenses for a month of August mortgage payment was 347.90Insurance $17 Texas $84 electricity $64.40 phone service $33.50 fuel $98.25 water $17.44 in repairs $79.87 .Her monthly take-home pay is 2150 what's her total money coast?
Answer:
the total monthly cost is $742.36
Step-by-step explanation:
The computation of the total monthly cost is shown below:
= Mortgage payment + insurance + taxes + electricity + phone service + fuel + water + repairs
= $347.90 + $17 + $84 + $64.40 + $33.50 + $98.25 + $17.44 + $79.87
= $742.36
hence, the total monthly cost is $742.36
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 ?
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

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

Answer:
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.
