Which ordered pair is NOT a solution to the inequality in the graph?
A. (0,0)
B.(-2,-4)
C.(0,2)
D.(-3,4)
Answers
Given:
The inequality is
[tex]y\leq 3x+2[/tex]
To find:
The ordered pair that is NOT a solution to the inequality in the graph.
Solution:
We have,
[tex]y\leq 3x+2[/tex]
Checking the inequality for (0,0), we get
[tex]0\leq 3(0)+2[/tex]
[tex]0\leq 2[/tex]
So, the equality is true for (0,0). it means (0,0) is a solution of given inequality.
Checking the inequality for (-2,-4), we get
[tex]-4\leq 3(-2)+2[/tex]
[tex]-4\leq -6+2[/tex]
[tex]-4\leq -4[/tex]
So, the equality is true for (-2,-4). It means (-2,4) is a solution of given inequality.
Checking the inequality for (0,2), we get
[tex]2\leq 3(0)+2[/tex]
[tex]2\leq 2[/tex]
So, the equality is true for (0,2). It means (0,2) is a solution of given inequality.
Checking the inequality for (-3,4), we get
[tex]4\leq 3(-3)+2[/tex]
[tex]4\leq -9+2[/tex]
[tex]4\leq -7[/tex]
This statement is not true. So, the equality is false for (-3,4). It means (-3,4) is not a solution of given inequality.
Therefore, the correct option is D.

Answers
Answer:
1 .4x2-9= 2x+3,2x-3
2 .16x2-1=4x-1,4x+1
3 .16x2-4=4(2x+1)(2x-1)
4 .4x2-1=(2x+1)(2x-1)
Step-by-step explanation:
16x² − 1 = (4x − 1)(4x + 1) ; 16x² − 4 = 4(2x + 1)(2x − 1); 4x² − 1 = (2x + 1)(2x − 1) ;
4x² − 9 = (2x + 3)(2x − 3)
16x² − 1 is the difference of squares. This is because 16x² is a perfect square, as is 1. To find the factors of the difference of squares, take the square root of each square; one factor will be the sum of these and the other will be the difference.
The square root of 16x² is 4x and the square root of 1 is 1; this gives us (4x-1)(4x+1).
16x² − 4 is also the difference of squares. The difference of 16x² is 4x and the square root of 4 is 2; this gives us (4x-2)(4x+2). However, we can also factor a 2 out of each of these binomials; this gives us
2(2x-1)(2)(2x+1) = 2(2)(2x-1)(2x+1) = 4(2x-1)(2x+1)
4x² − 1 is also the difference of squares. The square root of 4x² is 2x and the square root of 1 is 1; this gives us (2x-1)(2x+1).
4x² − 9 is also the difference of squares. The square root of 4x² is 2x and the square root of 9 is 3; this gives us (2x-3)(2x+3).

$8,600 * 2yrs = $17,200
$1,600 * 2yrs = $3200
$3200 + $5980 = $9180
$17,200 - $9,180 = $8,020
She need to save $8, 020 more

Write an equation for the hanger diagram and then us the sketch to show how to solve the equation algebraically.
Answers
Step-by-step explanation:
Since there are 3 w's and a 1 on one side and 7 1's on the other and the hanger diagram shows they are even, we can set them equal to each other.
3w + 1 = 7 Subtract 1 from both sides
3w = 6 Divide 3 from both sides
w = 2

Q. A dice shows the numbers 1 through 12, with one number showing each time the die is rolled. What is the probability of rolling a 7?
Answers
Answer:
1/12
Step-by-step explanation:
The total number is 12 (assuming the dice would be rolled 12 times) 7 is a number in the range and it will appear once in the 12 rolls because each number shows each time. 1 (how many times 7 will show)/ 12(total number of rolls)
Probability of [tex]7[/tex] when a dice (showing numbers 1 throught 7) is thrown is equal to [tex]\boldsymbol{\frac{7}{12}}[/tex] as a dice is rolled.
Define probability.Probability refers to chances of occurrence of any event.
Value of probability lies in the interval [tex]\boldsymbol{\left [ 0,1 \right ]}[/tex]
Total number of numbers on a dice [tex]=12[/tex]
Probability is equal to number of favorable outcomes divided by the total number of outcomes.
Probability of [tex]7=\frac{7}{12}[/tex]

Stephanie puts 30 cubes in a box. The cubes are inch on each side. The box holds 2 layers
with 15 cubes in each layer. What is the volume of the box?
Answers
Answer:
[tex] 11.25\: {in}^{3} [/tex]
Step-by-step explanation:
Since, box contains two layers of cubes and each layer has 15 cubes.
So, length = 15*1/2 in = 7.5 in,
width = 3*1/2 in = 1.5 in
height = (1/2 + 1/2) = 1 inch
Volume of box = lbh
= 7.5* 1.5 *1
= 11.25 cubic inches

After you have -4 down, you will see that A's point on the graph is (-4, ?)
To answer the ?, you will have to check the y.
Because remember, The x-coordinate always comes first, followed by the y-coordinate.
