Answer:
A= 2
B= -1
Step-by-step explanation:
Do rise over run but make sure B is negative as it is going downwards
Answer:
A= 2 B= 9/10 (0.9)
Step-by-step explanation:
to find the gradients, we need to use the formula:
rise / run ---> which is basically counting the "boxes" in both of the x and y axis and divide them together (rise=y, run=x)
like that
A:
x axis=5 y=10 ---> then we use the formula (rise/run) 10/5= 2
B
x axis=10 y=9 ---> then we use the formula (rise/run) 9/10= 0.9
but since B is going downhill, it'll be -0.9
Stephen purchased a guitar, which was originally priced at $80 but discounted at 25%. He also had to pay 5% sales tax. What amount did Stephen pay to purchase the guitar?
Answers
Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.

Answers
Answer:
x= 2 or x= -3
Step-by-step explanation:
Bring the equations together using a common denominator (x-5) (x+7)
x-29/(x-5) (x+7)= 1
Multiply both sides by (x-5) (x+7)
x- 29= (x-5) (x+7)
x- 29= (x-5) (x+7)= x^2 + 2x - 35
-x^2 - x + 6 = 0
-(x-2)(x+3)= 0
Multiply both sides by -1
(x-2)(x+3)= 0
Split it into two equations
x-2= 0 or x+3= 0
x= 2 or x= -3

Transformations on a Map
Use the map of the United States and your centimeter cube to do the following transformations. Pay attention to which axis for reflections.
1. Start in Hawaii on the black-dot.
a. Reflect over the y-axis. Color this square blue. What ocean are you
in?
b. Go back to Hawaii. Now, reflect over the x-axis. Color this square green. What states are you in?
2. Start in Georgia on the black-dot.
a. Reflect over the x-axis. Color this square yellow. What states are you
touching?
b. Go back to Georgia. Now, reflect over the y-axis. Color this square black. What state are you in?
3. Start in Ohio on the square that says Ohio.
Describe a translation that would get you to Montana.
4. Start in Louisiana on the black dot. Rotate 90 degrees counter clockwise. Name a state in the quadrant you land in. (Can you name its capital??)
5. Start in New York on the black dot. Translate left 4 and down 3. Then reflect the cube over the x-axis. Color this square purple. What state are you in?
6. Start in south Dakota on the black dot .
a. Reflect over the x-axis. Color this square orange. What state are
you in?
b. Then reflect your cube over the y-axis. What quadrant are you in?
7. Start in Kansas on the black dot. Reflect over the y-axis and then translate your cube 6 right and 2 up. Color the square pink. What state are you in?
8. Start in New Hampshire on the black dot. Describe a way you could get to any square in the state of Texas. You may need to use more than one transformation to do this.
9. Start in Idaho on the black dot. Translate 6 right and 3 down. Now, reflect your cube over the y-axis. Color the square red. What state are you in?
Then describe the translation that would get you back to Ohio.
10. Start in Mississippi on the black dot. Rotate 90 degrees clockwise. What quadrant are you in?
BONUS: Start in North Carolina on the black dot. Reflect over the y-
axis. Translate 5 up and 4 right. Reflect over the y-axis. Translate 4 down. Rotate 180 degrees counterclockwise. Shade the box.
Answers
Answer:
1a.) atlantic
1b.) california
2a.) Tennesee and north carolina
2b.) new mexico
3a.) Add three and reflect accross the x axis
4.) texas (austin), quadrant 3
5.) alabama
6a.) texas
6b.) quadrant 4
7.) penslyvannia
8.) reflect accross x and y axis (or rotate clockwise by 180 degrees) then go 8 right and up 3
9.) missouri
9b.) up 1 and right 3
10.) quadrant 3
bonus.) i colored it gray and it's in wisconsin
Step-by-step explanation:
1a.) to reflect over the y axis you keep the y axis but swap the x to a negative
1b.) to reflect over the x axis you keep the x value the same but y's sign is swapped
2a.) I've already explained how to reflect something over the x axis
2b.) I've already explained how to reflect something over the y axis
3a.) ohio lies around (5,3) and montana is around (-5,6) so to get their just go up (or north?) three and reflect accross the y axis
4.) louisana is around (2,-3) and to rotate 90 degrees clockwise would make the coordinates (-3, -2) which puts you around Texas
5.) new york's coordinates are around (8,5) to go left 4 and down three puts you at (4,2) to reflect it over the x axis gives you the coordinates (4,-2) which is in alabama
6a.) south dakota is around (-2,5) and to reflect it over the x axis gives you (-2,-5) which is texas
6b.) To reflect (-2,-5) over the y axis gives you (2,-5) which is gives you the fourth quadrant
7.) Kansas is around (-1,2) and to reflect over the y-axis gives you (1,2) and to go 6 right and 2 up gives you (7,4)
8.) new hampshiere is around (9, 6) and to get to texas which is around (-1,-3) so let's flip accross the x and y axis to get (-9,-6), then go 8 right and up 3
9.) idaho is around (-8,5) and to get 6 right gets you (-2,2) and to reflect over the y axis gives us (2,2) which is missouri and to get to ohio would require us to to get to (5,3) which would require us to go up 1 and right 3
10.) mississippi is around (3,-2) and to rotate 90 degrees clockwise puts us at (-2,-3) or (y,-x) which is quadrant 3
bonus.) north carolina is around (7,1), to reflect over the y axis puts us at (-7,1), to go up 5 and 4 right puts us at (-2,5) and to rotate 180 degrees clockwise gives us (2,-5)

A square has two lengths, (6x-1)cm and (4x+6)cm.
What is the length of one side of the square, the answer must be written in the form, side=.......cm
Answers
9514 1404 393
Answer:
side = 20 cm
Step-by-step explanation:
We assume the two given lengths are sides of the square, so are equal to each other.
6x -1 = 4x +6
2x = 7
We could find x = 3.5, but we can use 2x, too.
(2)(2x) +6 = 2(7) +6 . . . find the side length
4x+6 = 20 . . . . the side length of the square
__
side = 20 cm
Them sum of two numbers is 17. One number is 3 less than 2/3 of the numbers. What is the lesser number?
Answers
Answer:
The smaller number is 5
Step-by-step explanation:
Let the smaller number be x
the other number is (17 -x) (we know they add up to 17)
2/3 of the bigger number is written as 2/3 (17 - x)
The smaller number is 3 less than that. (so subtract 3 to get x)
x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x
Check 2/3 x 12 - 3 = 8 - 3 = 5
Please explain how to solve y=2x+4 and y=x-3 (EXPLAIN please, not doing the work)
