Answer 1

Answer:

D. y = { -x + 2 x ≥ 1}

{ x + 1 x < 1}

Step-by-step explanation:

First is to eliminate A and C, why?

This is because of the end points shown on the graph.

As shown, if you look at the point of (2,1) it is black, this means that not only is it closed but it is also means ≤ or ≥ symbol.

You are now left with B and D

The difference between these two is the symbols; they are facing the opposite directions.

While B says x ≤ 1, and x > 1

While D says x ≥ 1, and x < 1

The direction of the symbols depends on the direction of the lines and what is part of it (some what like a shaded area)

So you answer would be D

Find the values of x and y.
4x(7y - 12)
(6y + 8) (6x-26)

Answers

Answer:

x = 13

y = 20

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached.

In line geometry, the oppositely directed angles are equal. According to the diagram shown;

4x = 6x - 26 (oppositely directed angles)

We can get the value of x from the equation as shown;

4x = 6x - 26

Subtract 6x from both sides

4x-6x = 6x-6x-26

-2x = -26

x = -26/-2

x = 13

Similarly:

6y+8 = 7y-12 (oppositely directed angles)

collect like terms

6y-7y = -12-8

-y = -20

multiply both sides by -1

-(-y) = -(-20)

y = 20

Hence x = 13 and y = 20

John has a goal to ride his bike 100 miles this summer. John has ridden 12 miles thus far. There are only 40 days left in summer. Write a inequality to represent the average distance, d, in miles, John must ride each day for the rest of summer

Answers

Answer:

12 + 40d ≥ 100

Answer:

y[tex]\geq 2.2[/tex]

Step-by-step explanation:

John wants to complete at least 100 miles. he has completed 12 which means he only has 88 left. If you divide 88(miles left) by 40(time left) you get 2.2 miles. so he would need a minimum of 2.2 miles a day to bike 100 miles.

5(x + 4) = 5(x-6)
5(x + 4) = 3(x-6)
4(x - 2) = 4(x + 2)
x + 2(x - 5) = 3(x - 2) - 4

Answers

Answer:

1. 2(x - 5) = 2(x - 5) has infinitely many solutions

2. 5(x + 4) = 5(x-6) has no solution

3. 5(x + 4) = 3(x-6) has one solution

4. 4(x - 2) = 4(x + 2) has no solution

5. x + 2(x - 5) = 3(x - 2) - 4 has infinitely many solutions

Step-by-step explanation:

I did the assignment and I got it correct edge2020

1. 2(x-5)= 2(x-5) = Infinitely many solutions.

2. 5(x+4) = 5(x-6) = No solution

3. 5(x+4) = 3(x-6) = One solution

4. 4(x-2) = 4(x+2) = No solution

5. x+2(x-5) = 3(x-2) - 4 = Infinitely many solution

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now,

The given equations is;

1. 2(x-5) = 2(x-5)

2x-10 = 2x-10

0=0

Hence, This equation has infinitely many solution

2. 5(x+4) = 5(x-6)

5x+20 = 5x-30

20 ≠ (-30)

Thus, This equation has no solution

3. 5(x+4) = 3(x-6)

5x+20 = 3x -18

5x-3x = -20-18

2x = -38

x=-19

Thus ,this equation has one solution

4. 4(x-2) = 4(x+2)

4x-8 = 4x+8

-8 = 8

Thus, this equation has no solution

5- x+2(x-5) = 3(x-2) -4

x+2x-10 = 3x-6-4

3x-10 = 3x-10

0=0

Thus, this equation has infinitely many solution

The expression one hundred seventy-five ten-thousandths in the standard form will be 175,000. The correct option is A.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the number is one hundred seventy-five ten-thousandths. The standard form of the number can be written as below,

Standard form = one hundred seventy-five ten-thousandths

Standard form = 175,000

Hence, the standard form is 175,000.

A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down. Which rule describes the translation?

(x, y) → (x + 3, y – 4)
(x, y) → (x + 3, y + 4)
(x, y) → (x + 4, y – 3)
(x, y) → (x + 4, y + 3)

Answers

Answer:

The third option, or (x, y) ---> (x + 4, y - 3)

Step-by-step explanation:

When moving right on the horizontal axis, you always add so since we are moving 4 units to the right, that would be x + 4, and when moving down on the vertical axis, we always subtract, so since we are moving 3 units down, that would be y - 3

Answer:

(x + 4, y - 3)

Explanation:

We’re graphing the coordinate points of a triangle. Since we’re translating 4 units to the right we’re going off the x axis. So, it would be positive (x + 4). Then, you’re translating 3 units down which would be negative because you’re moving into the negative part of the graph, and you’re going down the y axis. (x - 3).

how do i write the intercept form equation
y=a(x-p)(x-q)
when i know a=-16
p=-0.12
q=1.12

Answers

Answer:

y = -15x - 3.04

Step-by-step explanation:

1) First place down what you are given.

Y = a(x - p) (x - q)

2) Then Substitute.

a = -16

p = -0.12

q = 1.12

y = (-16)(x - (-0.12))(x - (1.12)

3) Do order of operations (PEMDAS)

y = (-16)(x + 0.12)(x - 1.12)

Now distribute

y = − 16 x − 1.92 + (x - 1.12)

y = -16x - 1.92 + x - 1.12

y = -16x + x - 1.92 - 1.12

y = -15x - 3.04

You answer is:

y = -15x - 3.04
