Answer:
y=x-2
a. 3=x-2
b. this isn't wrong??
c. 3=x-2
d. add 2 to both side so taht x is on its own so 5=x
e. yes
Answer:
C and E
Step-by-step explanation:
Im not entirely sure about A, because you are substituting so technically you changed it but the equation is still true (just as E says) but with more specific values.
B is not right because you can replace either y or x
D is not right because if you switch the equation to get the value of x you would make x= -3-2 which would be -5, not 5.
Hope this helped :)

Ann bought 4 souvenirs during 2 days of vacation. How many days will ann have to spend on vacation before she will have bought a total of 16 souvenirs solve using unit rates.
Answer: She will have to spend 8 days on vacation before she will have bought a total of 16 souvenirs.
Step-by-step explanation:
Given: Ann bought 4 souvenirs during 2 days of vacation.
Per day she buys =[tex]\dfrac{4}{2}=2[/tex] souvenirs [unit rate]
To buy 16 souvenirs , she will take [tex]\dfrac{16}{2}[/tex] = 8 days.
Hence, she will have to spend 8 days on vacation before she will have bought a total of 16 souvenirs.

The volume of the large cube is 125 cubic inches. The volume of the small cube is 27 inches. What is the difference between the length of one side of the large cube and the length of one side of the small cube?
Answer:
2cmStep-by-step explanation:
Step one:
given data
for the large cube
the volume= 125cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
125=l^3
l=∛125
l=5cm
Step two:
given data
for the large cube
the volume= 27cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
27=l^3
l=∛27
l=3cm
The difference between the length of one side of the large cube and the length of one side of the small cube=5-3= 2cmI'll mark you the brainiest if you get this right

Answers in picture.
Answer:
so lets have 4 domains meaning what x could be 3,6,10,20
Step-by-step explanation:
so you must replace the x's with that number
so x=3
f(3)=2(3)-4 2*3=6 6-4=2 so f(3)=2
y is 6
f(6)=2(6)-4 2*6=12 12-4=8 so f(6)=8
y is 8
x=10
f(10)=2(10)-4 2*10=20 20-4=16 so f(6)=16
y is 16
x=20
f(20)=2*20-4 2*20=40 40-4=36 so f(20)=36
y is 36

A nightclub has approximated the demand for their Thursday night drink special by p^2+200q^2=177, where p is the price (in dollars) and q is the quantity demanded (in thousands). Find and interpret when the price is $ 7 and the demand is 800 drinks.
Answer:
Step-by-step explanation:
Given the approximate demand function of night drink expressed as;
p^2+200q^2=177,
p is the price (in dollars) and;
q is the quantity demanded (in thousands).
Given
p = $7
q = 800
Required
dq/dp
Differentiating the function implicitly with respect to p shown;
2p + 400d dq/dp = 0
400q dq/dp = -2p
200qdq/dp = -p
dq/dp = -p/100q
substitute p and q into the resulting equation;
dq/dp = -7/100(800)
dq/dp = -7/80000
dq/dp = -0.0000875
This means that the rate of change of quantity demanded with respect to the price is -0.0000875

Given that two sides of a triangle have sides 5 and 7, write the range of the lengths of the third side:
Question Blank
type your answer...
< x
<
Question Blank
type your answer...
Plz due 11:59
Answer:
Step-by-step explanation:
The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.
So the maximum value must be less than 12. What's the smallest x could be?
well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?
5 + y > 7
5 - 5 + y > 7 - 5
y > 2
So the range is 2 < x < 12
How else could you write this?
2 < x
x < 12 is one way.

Step-by-step explanation:
A baseball diamond is a square with side 90 feet. A batter hits the ball and runs toward first base with a speed of 24 ft/sec. At what rate is his distance from second base decreasing when he is halfway to first base?
9514 1404 393
Answer:
10.73 ft/s
Step-by-step explanation:
When the runner is halfway to first base, the triangle formed by his position and the first and second bases is a right triangle with legs of 45 ft and 90 ft. The angle between the runner's direction and the line from his position to 2nd base is ...
angle = arctan(90/45) ≈ 63.43°
The "speed made good" in the direction of 2nd base is the product of the cosine of this angle and the runner's speed toward first.
speed toward 2nd = cos(63.43°)×(24 ft/s) ≈ 10.73 ft/s
The rate the runner's distance to 2nd base is decreasing is 10.73 ft/sec.

QUESTION 2
What type of angles are 1 and 8 ?
Answer:
A. None of the answers are correct
Step-by-step explanation:
∠3 is a verticle angle to ∠1
linear pair means they add up to 180
complementary mean they add up to 90
Answer:
None of the answers are correct.
Step-by-step explanation:
1 and 8 are corresponding angles.
They are not vertical because vertical angles look like this ><
They are not a linear pair because linear pairs = 180 and right next to each other.
They are not complementary angles because complementary angles = 90
And 1 and 8 are more that 90.
So it's A

Answer:
60 yds
Step-by-step explanation:
10 + 15 + 4 + (10 - 4) + 20 + (20 - 15) = 60
Answer: 60 Yards
In this model, we have all sides except for two. In order to find the perimeter of this, you would need all sides.
To find the missing sides you can see that the lenght of the side on the left is 10 yards. And the entire right side is equal to that left side. So, to find the missing side x you would need to solve: x+10-4. So, x is 6.
Do the same for the top and bottom to get the other missing side that is perpendicular to the side that is 4 yards is 5 yards.
Now that you have the lengths of all of the sides, you can solve for the perimeter. You would do,
[tex]15+4+6+20+10+5=60[/tex]
Please mark brainliest if correct :)
