Plot the point that is symmetric to (0,-5) with respect to the x-axis
Answer:
If this point is 0, -5, one of the points of symmetry would be a simple reverse on the y axis. It would be 0, 5.
If we are talking respect to the x axis in general, another reverse point or quadrant would be -5, 0.

Add or subtract each fraction
2 + 15/8
Answer:
3 7/8
Step-by-step explanation:
2 + 15/8 = 2/1 + 15/8
Let's add 2/1 + 15/8 like this:
2/1 × 8/8 = 16/8
16/8 + 15/8 = 31/8
Since that is an improper fraction, we will simplify it.
31/8 = 3 7/8
A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for ∏.
Answer:
66
Step-by-step explanation:
The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D

NEED HELP NOW!!!!
WILL GIVE 40 POINTS!!!!
Answer:
im guessing it is 78/100 because u circled 78
Step-by-step explanation:
because 21 + 1 + 78 = 100
so 78/100 is the fraction
Answer:
78/100 or 39/50 (simplified)
Step-by-step explanation:
First, let's convert 78% into a decimal.
78% = 0.78Now, we know that 0.78 is the same thing as 78/100. We can simplify 78/100 into 39/50, where 2 is the GCF
Thus, the answer is 78/100 or 39/50.

Radhika buys papaya at the rate of p(x) = x² – 12x – 220 per kg
(i) the factors of the given polynomial
(ii) if she purchase 5kg papaya, what money she have to pay?
Answer:
(i) The factors of the given polynomial is (x – 22) and (x + 10)
(ii) If she purchase 5kg papaya then she pays 110
Step-by-step explanation:
Given;p(x) = x² – 12x – 220 per kgTo Find;The factors of the given polynomialif she purchase 5kg papaya, what money she have to pay?(i)Now,
x² – 12x – 220 = 0
Splitting the middle term
x² – 22x + 10x – 220 = 0
x(x – 22) + 10(x – 22) = 0
(x – 22) + (x + 10) = 0
x – 22 = 0 or x + 10= 0
x = 22 or x = -10
Here, (-10) is the negative value hence it is not possible
So, The value of x is 22
The factors of the given polynomial is (x – 22) and (x + 10)
(ii)if she purchase 5kg papaya then,
we know the price of 1 kg papaya i.e., 22 per kg
So,
5 × 22 = 110
Thus, if she purchase 5kg papaya then she pays 110

a bakery sold 10 more cakes this month than it did the last month. It also sold 3 times as many cakes in this month than in the month before the last month. If that total number of cakes it sold in the last 3 months is 116, how many cakes did it sell last month?
Answer:
Last month it sold 338 cakes.
Step-by-step explanation:
Let total cakes this month,last month and last 3 months be x,y and z respectively,
x = y + 10...
x = 3z
z = 116
Now, we have to find y,
x = y + 10
or, 3z = y + 10
or, 3•116 = y + 10
or, 348 = y + 10
or, y = 348 - 10
so, y = 338

Answer:
1) X + 234 = 633
2) t = 63
3) x = 12
Step-by-step explanation:
1 is simple subtraction, just subtract the whole by the number that is given. Then that will fill X.
2 is multiplication. If a variable is (for example, x) next to a number that means it is multiplying it by a hidden number. To find that, you multiply the number next to the variable. If the sum matches the solution, there you go.

Dave wants to buy 5 games, 10 Funko Pops, and 6 toys. He was $2,614 .If each game is $50, each Funko Pop is $30, and each toy is $40. How much money does Dave have left?
Answer:
$1,824
Step-by-step explanation:
Games Dave wants to buy: 5
Cost of each game: $50
Cost of 5 games = $50 x 5
= $250
Funko pops Dave wants to buy: 10
Cost of each funko pop: $30
Cost of 10 funko pops = $30 x 10
= $300
Toys Dave wants to buy: 6
Cost of each toy: $40
Cost of 6 toys = $40 x 6
= $240
Sum of all Dave's things = ($250 + $300 + $240)
= $790
Money Dave has = $2,614
Money left with him = ($2,614 - $790)
= $1,824
Hence, $1,824 are left with Dave after buying 5 games, 10 Funko pops and 6 toys.
Pls correct me, if I am wrong :)

One number is 3 less than 4 times a second number. The difference of the
first number and twice the second number is 7. What are the two numbers?
Show your work.
Answer:
the two numbers are 5 and 17
Step-by-step explanation:
4y - 3 = x
x - 2y = 7
to find y:
x - 2y = 7
(4y - 3) - 2y = 7
2y - 3 = 7
2y = 7 + 3
2y = 10
y = 10/2
y = 5
to find x :
4y - 3 = x
4 ( 5 ) - 3 = x
20 - 3 = x
17 = x

A cuboid has total surface area of 280m2 breadth 5cm and heinght 6cm.Find its length
Step-by-step explanation:
Solution,
In the given cuboid, area of total surface (A)=280 cm²
Breadth ( b ) = 5 cm
Height ( h ) = 6 cm
Total surface area of cuboid = 2 ( lb + bh + lh )
or , Area = 2 ( lb + bh + lh )
or , 280 = 2 ( l × 5 + 5 × 6 + l × 6 )
or , 280 = 2 ( 11 l + 30 )
or , 2 ( 11 l + 30 ) = 280
or , 11 l + 30 = 280 ÷ 2
or , 11 l + 30 = 140
or , 11 l = 140 - 30
or , 11 l = 110
or , l = 110 ÷ 11
l = 10
Thus, the length is 10 cm...

Answer:
x has to be greater than 0
Step-by-step explanation:
It basically shows you that based on the inequality sign.
Answer:
x solved is 0 < x
and graphing it on the number line
-1 0 1
O->
Step-by-step explanation:
So, solving for x is easy you divide the 2 from 2x onto the other side and 0/2 is 0 meaning 0 < x, the < stays the same as you divided with a positive and it would start at 0 and the line would go to the right as 0 is less than x. if you have to it would be a open circle with a dotted line if deltamath makes you do that too.

I’m confused, mostly on 4. How can you prove it, and are they parallel?
Answer:
It is parallel and yes you can prove it.
Step-by-step explanation:
I would use a tool that you can use to figure out the angle, check all the corners and if the smaller one are the same and the wider corners are the same then then would be parallel. That only works though if there was a line going through like your problems. If you had a graph it would be easier.
