Answer:
(1,3)
Step-by-step explanation:
starting at (0,0)
vertically scaled by 4 - go up four (0,4)
reflected on y axis - negative the four (0,-4)
translated 1 to the right and 7 up - go up 7 and to the right 1 (1,3)

Avril is reading the first Harry Potter book, Harry Potter and the Sorcerer's Stone. The book has a total of
308 pages. If Avril has read 33 pages after reading for 18 minutes, will she be able to finish the book in 3
hours? Depending on how long it takes Avril to read the book, how many more minutes will she need or
how many extra minutes will she have before 3 hours have passed?
Nicholas has 22 nickels, dimes, and quarters. There are 3
less dimes than quarters and 2 more dimes than nickels.
How much money does he have?
Nickels: 22
Dimes: 24
Quarters: 27
2 more dimes than nickels, we already know that there are 22 nickles so...
Dimes= 24
3 less dimes that quarters ^(we already know how many dimes).
All we have to do is add 3 to the amount of dimes!
Quarters 27
____________________________________________________________
Now to find the amount of money you have to find out what each coin equals and multiply the number of coins by the cost of each coin, and then by 100 because there are 100 cents in 1 dollar.
22 nickels*5/100= $1.10
24 dimes*10/100= $2.40
27 quarters*25/100= $6.75
1.10+2.40+6.75= $10.25
The amount of money he has in $10.25

B jada writes this equation for the sum of the ages (x)+(x+3) +3(x+3)-1=87 explain the meaning of the variable and each term of the equation.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex](x)+(x+3) +3(x+3)-1=87[/tex]
simplifying the equation
[tex]x+x+3+3x+9-1=87[/tex]
adding similar elements
[tex](x+x+3x)+(3+9-1-87)=0[/tex]
[tex]5x-76=0[/tex]
Thus, the equation is a linear equation in one variable 'x'.
A term is a single mathematical expression, so the simplified expression has two terms which are:
5x-76The term 5x has the variable 'x' of power 1.
The term -76 does not involve any variable, Hence, -76 is a constant term.

Which system of equations can you use to find the roots of the equation 2x3 + 4x2 – x + 5 = –3x2 + 4x + 9? y = 2x3 + x2 + 3x +5 y =9 y = 2x3 + x2 y = 3x + 14 y = 2x3 + 4x2 – x + 5 y = –3x2 + 4x + 9
Answer:The answer is y = 2x3 + 4x2 – x + 5 and y = –3x2 + 4x + 9
Roots are both: x=-4, x= -1/2 , x= 1
Proof:
Solve for x over the real numbers:
2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9
Subtract -3 x^2 + 4 x + 9 from both sides:
2 x^3 + 7 x^2 - 5 x - 4 = 0
The left hand side factors into a product with three terms:
(x - 1) (x + 4) (2 x + 1) = 0
Split into three equations:
x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0
Add 1 to both sides:
x = 1 or x + 4 = 0 or 2 x + 1 = 0
Subtract 4 from both sides:
x = 1 or x = -4 or 2 x + 1 = 0
Subtract 1 from both sides:
x = 1 or x = -4 or 2 x = -1
Divide both sides by 2:
Answer: x = 1 or x = -4 or x = -1/2
Step-by-step explanation:
The answer is y = 2x3 + 4x2 – x + 5 and y = –3x2 + 4x + 9
Roots are both: x=-4, x= -1/2 , x= 1
Explanation:
Solve for x over the real numbers:
2 x^3 + 4 x^2 - x + 5 = -3 x^2 + 4 x + 9
Subtract -3 x^2 + 4 x + 9 from both sides:
2 x^3 + 7 x^2 - 5 x - 4 = 0
The left hand side factors into a product with three terms:
(x - 1) (x + 4) (2 x + 1) = 0
Split into three equations:
x - 1 = 0 or x + 4 = 0 or 2 x + 1 = 0
Add 1 to both sides:
x = 1 or x + 4 = 0 or 2 x + 1 = 0
Subtract 4 from both sides:
x = 1 or x = -4 or 2 x + 1 = 0
Subtract 1 from both sides:
x = 1 or x = -4 or 2 x = -1
Divide both sides by 2:
Answer: x = 1 or x = -4 or x = -1/2

In a scale drawing of a house, 2 inches : 5 feet. The actual kitchen of the house will be 17 feet long. How long will the drawing of the kitchen be?
A. 5.2
B. 6.8
C. 7.5
D. 8
Answer:
B, 6.8
Step-by-step explanation:
Let's first find how many feet it is per 1 inch. We can do this by dividing 5 by 2
5/2= 2.5
Now it is 1 inch : 2.5 feet
17/2.5 = 6.8
1 x 6.8 = 6.8
6.8 inches : 17 feet
You could also solve this by doing
17/5 =3.4
3.4 x 2 = 6.8
6.8 inches : 17 feet

Solve the equation : (3.2y-1.8)-(5.2y+3.4)=-5.8
Answer:
y = 0.3
Step-by-step explanation:
[tex](3.2y-1.8)-(5.2y+3.4)=-5.8 \\ \\ = 3.2y - 1.8 - 5.2y - 3.4 = - 5.8 \\ \\ 3.2y - 5.2y - 1.8 - 3.4 = - 5.8 \\ \\ - 2y - 5.2 = - 5.8 \\ \\ - 2y = 5.2 - 5.8 \\ \\ - 2y = - 0.6 \\ \\ y = \frac{ - 0.6}{ - 2} \\ \\ y = 0.3[/tex]
Answer
y= -11/2
Explanation
3.2y-+1.8-5.2y-3.4=-5.8
Collect like terms
-2y-5.2=-5.8
Move the constant to the right
-2y=5.8+5.2
Calculate

Graph the line with slope
1/2 and y-intercept -9
Answer:
Step-by-step explanation:
slope is the x axis and y intercept is the y axis
so 1/2 will go on the x axis and -9 will go on the y axis
1/2 uses the rise over run method
Answer:
Answer is in the screenshot. The equation for the line is y=1/2 x - 9
Step-by-step explanation:
To graph a line when you know the slope and y intercept, you make a point on the y intercept. Your y intercept iIs -9 so you would make a point on (0,-9).
After you have the point on (0,-9) you use the slope to create the rest of your line. Slope is just Rise
Run
Your slope is 1/2. That means your next point on the line is up 1 unit and right 2 units. The next point on the line is (2,-8).
