Kevin graphed the inequality x > 1.
A number line going from negative 3 to positive 5. A closed circle is at 1. Everything to the right of the circle is shaded.
What mistake did Kevin make? Explain.
.
Answers
Answer:
Sample: Kevin should have used an open circle on 1, not a closed circle. The closed circle means that 1 is included in the solution set, but the inequality is x > 1, so 1 is not part of the solution.
Mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.
What is open and closed circles?
" Closed circle represents that the value is included in the given range while that of open circle represents given number is not included."
According to the question,
Graph of inequality x > 1 represents all values greater 1 excluding 1.
Number line represents -3 to 5.
A closed circle at 1 means 1 is included.
As per the condition of inequality x > 1 , 1 is excluded while in closed circle 1 is included both are contradictory conditions.
Hence, mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.

Which statement is true about a shape and its dilation? A.The corresponding angles of a shape and its dilation are congruent. B.The corresponding angles of a shape and its dilation are not congruent. C.The side lengths of a dilation are always smaller than the corresponding side lengths of the original shape. D.The corresponding side lengths of a shape and its dilation are congruent.
Answers
Answer:
A.The corresponding angles of a shape and its dilation are congruent.
Step-by-step explanation:
Dilation is a type of rigid transformation in which the dimension of a shape is either increased or decreased to produce its image. It involves a change in the dimensions of the shape by a required factor. In the process, the side lengths of the image are different to the original lengths. But the angles are not affected.
Thus, the respective angles of the given shape and its image are the same.
The appropriate answer to the given question is A.

which orders paid is a solution is the equation y= 4x + 9
Answers
Note: you did not add the answer options, so I am solving this question generally to solve your query, which anyways would clear your concept.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]y= 4x + 9[/tex]
All we need is to find any random value of 'x' and then solve for 'y'.
For example, putting x=2
[tex]y= 4x + 9[/tex]
[tex]y=4(2)+9[/tex]
[tex]y=8+9[/tex]
[tex]y=17[/tex]
Thus, (2, 17) is one of the many ordered pairs solutions of the equation.
Similarly, putting x=3
[tex]y= 4x + 9[/tex]
[tex]y=4(3)+9[/tex]
[tex]y=12+9[/tex]
[tex]y=21[/tex]
Thus, (3, 21) is one of the many ordered pairs solutions of the equation.

Step-by-step explanation:
Step 1: Define

Step 2: Solve for x
Distribute: 3 - 2x + 5 < -4x - 8Combine like terms: -2x + 8 < -4x - 8Add 4x on both sides: 2x + 8 < -8Isolate x term: 2x < -16Isolate x: x < -8Here we see that any value x smaller than -8 would work as a solution in the inequality.

B- move 1 unit left and 7 units down
Step-by-step explanation:
A- 4 units right is x so
(x+4,y__)
5 units down is y so
(x+4,y-5)
B- move 1 unit left and 7 units down
because (x-1,y__) is going left because of the subtraction sign and its the x-coordinate, and (x-1,y-7) is down because its a Y-coordinate and sub so its going down.
TIP- Going left/down is always subtract/negative going right/up is positive/addition.Tom reads 42 chapters of a book in 6 hours.

Victor baked 66 cookies with 11 scoops of flour. With 14 scoops of flour, how many cookies can Victor bake? Assume the relationship is directly proportional.
? cookies
Answers
Answer:
84 Cookies
Step-by-step explanation:
11/66= 14/x
11x=66*14
Solve for x
x=84
Answer:
84 cookies
Step-by-step explanation:
To solve this problem, we can use cross multiplication:
[tex]\frac{11}{66}=\frac{14}{x}[/tex]
66 * 14 = 924
11 * x = 11x
924 = 11x
924 ÷ 11 = 11x ÷ 11
84 = x
With 14 scoops of flour, Victor can bake 84 cookies.
Another way to solve this problem is to find how many cookies you can bake per cup of flour. To find this, divide the amount of cookies by the amount of cups of flour:
66 ÷ 11 = 6
You can make 6 cookies with 1 cup of flour.
So, to find how many cookies Victor can make with 14 cups, multiple 6 by 14:
6 * 14 = 84
Victor can make 84 cookies with 14 cups of flour.
