Diego was asked to plot these points: (−50,0) ( − 50 , 0 ) , (150,100) ( 150 , 100 ) , (200,−100) ( 200 , − 100 ) , (350,50) ( 350 , 50 ) , (−250,0) ( − 250 , 0 ) . What interval could he use for each axis?
Answer:
We have the points:
(-50, 0)
(150, 100)
(200, -100)
(350, 50)
(-250, 0)
First, we need to find the smallest and largest values of the x-component.
The smallest value is x = -250
The largest value is x = 350
Then the interval that we choose for the x-axis should include these two values (so we can plot the points)
Then we need to use, at least, the interval [-250, 350] (A interval that is a little bit larger than that will be easier to read, but that is the minimum he needs to do the plot)
Now let's do the same with the values of the y-components.
The smallest value is y = - 100
The largest value is y = 100
Then the vertical interval should be [-100, 100] or a little bit larger, like in the horizontal case.
We also can see that the values of x and y seem to jump in multiples of 50, then each unit of the grid could represent 50 units, so it is easier to plot. (These are also called intervals, and also theses will depend on each individual axis, but in this case we could use the same for both of them, because it works well for both axis)
Use an interval of 50, because all the
coordinates involve points that are greater than 50 and multiples of 50.

Stuck? Watch a video or use a hint.
Answer:
9
===================================================
Explanation:
The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.
The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135
Therefore, 15*b = 135
Divide both sides by 15 and we isolate b
15b = 135
15b/15 = 135/15
b = 9
So the base is 9
Check:
area = base*height = 9*15 = 135
so the answer is confirmed
side note: we never use the value 17 at all. It is likely put in there as a distraction.

In y = ax² + bx + c, what happens to the graph when a gets more negative?
A.The graph widens
B. The graph shifts left.
C. The graph shifts down
D. None of these
E. The graph narrows.
Answer:
A.
Step-by-step explanation:
It should be A. since if you have value that is greater than 1 then the graph would get narrower if you change the a value so this crosses E. out of the list

20 = n/4. Solve for n using reverse operations. Show all work. Your answer
Answer:
n=80
Step-by-step explanation:
n/4=20
(n/4=20)4 . to get rid of the denominator u multiply by 4 on both sides
n=80
If you multiply or divide both sides of an inequality by a negative number, you must __________ the inequality sign.
A
double
B
reverse
C
subtract
D
add an equal sign to
Answer:
B
Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a larger negative number, which actually means it is now less than the other side. This is why you mathematically have to flip the sign whenever you multiply by a negative number.

The weight of a giant panda is 10 times the weight of a red panda. The combined weight of the pandas is 220 pounds. What is the weight of each panda?
Answer:
The weight of a giant panda = x = 200 pounds
The weight of a red panda = y = 20 pounds
Step-by-step explanation:
Let
The weight of a giant panda = x
The weight of a red panda = y
The weight of a giant panda is 10 times the weight of a red panda.
x = 10y
The combined weight of the pandas is 220 pounds.
x + y = 220
We substitute 10 y for x
10y + y = 220
11y = 220
y = 220/11
y = 20 pounds
Solving for x
x = 10y
x = 10 × 20
x = 220 pounds
Hence:
The weight of each panda is:
The weight of a giant panda = x = 200 pounds
The weight of a red panda = y = 20 pounds

BRAINLIEST FOR THE CORRECT AWNSER!! PLEASE PUT THE LETTER AWNSER AND EXPLAIN DO NOT LIE THANK YOU The owner of a bike shop sells unicycles and bicycles and keeps inventory by counting seats and wheels. One day, she counts 15 seats and 22 wheels. The equation representing the total number of seats is u + b = 15 where u is the number of unicycles and b is the number of bicycles. Select the equation representing the number of wheels. A. u + 2b = 22 B. 2u + b = 15 C. u + 2b = 15 D. 2u + b = 22
Answer:
u+2b=22
Unicycles have one wheel and bicycles have two, so the coefficient of 2 should go before the variable representing each bike.
It should equal 22 because 15 represents the total number of seats and not wheels.

Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Function?
Answer:
[tex]D = \{-2,-1,3,5\}[/tex] -- Domain
[tex]R = \{-7,0,4\}[/tex] -- Range
It is a function
Step-by-step explanation:
Given
[tex]D = \{-2,-1,3,5\}[/tex]
[tex]R = \{-7,0,4\}[/tex]
Required
State the domain and range
Determine if the relation is a function
From the question, we have the domain and range as:
[tex]D = \{-2,-1,3,5\}[/tex] -- Domain
[tex]R = \{-7,0,4\}[/tex] -- Range
Next, is to determine if the relation is a function or not.
Yes, it is a function.
The number of elements in the domain is 4
The number of elements in the range is 3
When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.
Sinah bought some packs of gum. There were 8 sticks of gum in each pack. She gave 12 sticks of gum to manuela. This left sinah with 28 sticks of gum. Which equation can be used to represent this situation where g is the number of packs of gum that sinah bought?
Answer:
8g = 12 + 28
g = 5 packs
Step-by-step explanation:
Share of the sticks of gum
Manuela = 12 sticks
Sinah = 28 sticks
There are 8 sticks in each pack
g = number of packs of gum that sinah bought?
g × 8 sticks = 12 sticks + 28 sticks
8g = 40
Divide both sides by 8
g = 40 / 8
g = 5 packs
