Answer:
A-(x+4,y-5)
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.On a road map, the distance between 2 cities is 2.5 inches. The map scale is 1 inch:30 miles. What is the actual distance between the cities?

which orders paid is a solution is the equation y= 4x + 9
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.

Timed math PLEASE HELP 8th GRADE HELPPPPPPP
Answer:
John's and Amber's wages are proportional to time. John's unit rate it $9 per hour. Amber's unit rate is $8 per hour
Step-by-step explanation:
The table(johns) shows this because he earns $9 more for every extra hour he works. this makes the unit rate $9 an hour.
The graph(ambers) shows that her pay increases at a steady rate, hitting a multiple of 8 every hour. This makes the unit rate $8 an hour.

Find the unknown size of the angle
Answer:
I hope this guides you!
Step-by-step explanation:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut. If you can buy 2 dozen doughnuts for $8.40, how much does it cost Jane to make each doughnut?
Answer: $0.20
Step-by-step explanation: $8.4 divided by the 24 or 2 dozen dougnuts she sells means she sell each donut for $0.35 and if we know that Jane Dough sells her doughnuts for $0.15 more than what it costs her to make each doughnut then $0.35 - $0.15 = $0.20 to make each donut

Solve for x: 3 - (2x - 5) <-4(x + 2)
Answer:
x < -8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
3 - (2x - 5) < -4(x + 2)
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.

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.
.
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.
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.
What is the range of the function
f(x) = = 3x + 2 in the domain -2
Answer:
The range is:
{-4, 1, 2, 5, 8}
Step-by-step explanation:
Given the function
[tex]f(x)=3x+2[/tex]
We know that the domain of a function is the set of input or argument values for which the function is real and defined.As the domain interval -2 ≤ x ≤ 2
i.e. the values in the domain = {-2, -1, 0, 1, 2}
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.As the domain interval -2 ≤ x ≤ 2
Putting all the x-values in the domain interval in the function
so
putting x=-2 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(-2)=3(-2)+2=-6+2=-4[/tex]
putting x=-1 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(-1)=3(-1)+2=-3+2=1[/tex]
putting x=0 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(0)=3(0)+2=0+2=2[/tex]
putting x=1 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(1)=3(1)+2=3+2=5[/tex]
putting x=2 in the function
[tex]f(x)=3x+2[/tex]
[tex]f(2)=3(2)+2=6+2=8[/tex]
Thus, when we put the domain values, the corresponding range values are:
x y
-2 -4
-1 1
0 2
1 5
2 8
Therefore, the range is:
{-4, 1, 2, 5, 8}
