Answer:

D

Step-by-step explanation:

because both are x and y and they can be any number so no matter what the number is it will equal 4 and 2.

Answer: y= |x-1|+3

again lol used desmos graphing it’s 3 high so that +3 at the end and -1 to bring it to the side i’m bad at explaining

Answer:

The triangles are not similar.

Step-by-step explanation:

Look at ratios of corresponding sides. If the triangles are similar, all the ratios will be equal.

Compare a side from [tex]\triangle{RTS}[/tex] with a side from [tex]\triangle{MQP}[/tex].

16/20 = 4/5

12/15 = 4/5  (looks promising, so far!)

20/26 = 10/13   Not at all the same as 4/5, so the triangles are not similar.

Answer:

x + y = 680

5x + 7y = 3914

Step-by-step explanation:

Let the amount of students who purchased tickets equal x.

Let the amount of adults who purchased tickets equal y.

If you add the amount of adults and students, you get the total amount of people:

x + y = 680

Also, to find the amount students spent on tickets, you multiply the ticket price by the amount of students to get 5x. And to find the amount adults spent on tickets, you multiply the ticket price by the amount of adults to get 7y. By adding the two amount, you get the total amount of money:

5x + 7y = 3914

These are the two equations:

x + y = 680

5x + 7y = 3914

Answer:

If we were to use 3.14 as pi . . .

43.96/3.14 = 14

14/2 = 7

7 x 7 = 49

49 x 3.14 = 153.86

153.86 would be the correct answer

But if we were to use pi. . .

615.1279985 would be the answer.

Answer:154 rounded to whole number

Step-by-step explanation:

C=pi ×d

43.96 = 3.14 ×d

d= 43.96÷3.14

d= 14

So radius is 7 (half of diameter)

Area=3.14×7×7

=153.86

Answer:

65.12 ft^2

Step-by-step explanation:

Patio's area = area of trapezoid + area of semicircle

Area of a trapezoid = 1/2  x (sum of the lengths of the parallel sides) x height

1/2 x ( 12 + 8) x 4 = 40 ft^2

Area of semicircle =  (1/2)πr²

r = 8/2 = 4ft

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

(1/2) x 3.14 x 4^2 = 25.12 ft^2

Area of patio = 40 ft^2 +  25.12 ft^2  = 65.12 ft^2

t = 40

25.12

Answer: 8

Step-by-step explanation: since two opposites add up to zero, remove them from the expression. This simplifies to 4 + 4 which equals 8.

Answer:

49.923%

Step-by-step explanation:

Good Luck :D

Answer:

8.236%

Step-by-step explanation:

P(G,G,G) = 8/17 x 7/16 x 6/15

= 7/85 (simplified)

7/85, in decimal form, is .082352

.082352 in percent form is 8.236%

Step-by-step explanation:

b = 4`² = 1/16 = 0.0625

c = 4`⁴ = 1/256 = 0.00390625

d = (⅔)° = 1

e = (⅔)² = 4/9 = 0.4444...

f = (⅔)⁴ = 16/81 = 0.197530864

Answer:

Choice A, x=1

Step-by-step explanation:

So, to start, there's two routes that you can take there. I am going to show one of these routes.

Within the image, you see two triangles, you are able to tell that these triangles share two of the same sides, because of congruency lines on each of them.

The first group of congruent sides have 1 line going through them, the second group has 2 lines going through them. Let's go with the first group.

With the first group, we are using the lines CB and FE, where the measurements on each of them are 3x+1 and x+3 respectively.

Since they are congruent, they are equal and we can just set them equal to each other.

Starting With:

3x+1 = x+3

Step 1) Cancel out the +1

3x+1 -1 = x+3 -1

3x = x+2

Step 2) Cancel out the x

3x -x = x+2 -x

2x = 2

Step 3) Divide by 2 get x by itself

2x/2 = 2/2

x=1

All done!

Answer:

80-4(2)=72; 80-4(x) if he got x wrong.

Step-by-step explanation:

I have included a drawing of the triangle.

we can use Pythagoreans theorem.

a^2+b^2=c^2

So,

(4x)^2+(3x)^2=75^2

16x^2+9x^2= 5,625

we can add like terms.

25x^2 = 5,625

25 25

x^2 = 225

Square root both sides.

x = 15

so, leg of 4x is

4(15)= 60 m

leg of 3x

3(15)= 45 m

Answer:

Third zero is 4

Step-by-step explanation:

The polynomial is;

f(x) = x³ − 4x² − 3x + 12

We are given 2 zeros which are √3 and -√3.

This means that a factor of the polynomial will b; (x² - 3) because when it is equated to zero, x will be √3 and -√3.

Now, to get the other factor of the polynomial, we have to divide x³ − 4x² − 3x + 12 by (x² - 3) using long division method.

I have attached this long division method and we have the third factor as; (x - 4)

Equating to zero, we have x = 4 as the third zero of the polynomial
