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.

which expression is equivalent to 12^-5 times 12^9?
a. 1/12^-45
b. 12^-45
c. 1/12^4
d. 1/12^-4
Answers
Answer:
D. 1/12^-4
Step-by-step explanation:
[tex]12^{-5}*12^{9}[/tex]
Since both exponents have the same base, we can add the exponents to get:
[tex]12^{-5+9}=12^{4}[/tex]
We can cross out A and B since they multiplied the two exponents, therefore both answers are wrong.
Now, let's try C and D.
C is wrong because it has a different base being raised to the same power.
D is correct. When you have a negative exponent, it is equivalent to the reciprocal of the base to the positive exponent.
The reciprocal of 1/12 is 12, and the positive of -4 is 4, therefore the answer is D.

A cuboid has total surface area of 280m2 breadth 5cm and heinght 6cm.Find its length
Answers
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...

I’m confused, mostly on 4. How can you prove it, and are they parallel?
Answers
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.

y= 2x - 3
y= -1/2x- 3
y= -2x - 3
y= 1/2x - 3
Answers
Answer:
First option) y= 2x - 3
Step-by-step explanation:
[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.
[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.
-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.
[] Our equation is y = 2x - 3

A bag contains 4 red marbles, 3 blue marbles and 6 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 1000th, that both
marbles drawn will be red?
Answers
Answer:
~0.143
Step-by-step explanation:
So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a chance of being red. Since you didn't mention placing it back, the next draw will have a chance of being red. It's , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.
6/15 x 5/14 = 1/7 or (roughly) 0.143
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?
Answers
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

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?
Answers
y = funk pops
z = toys
50x + 30y + 40z = total
50(5) + 30(10) + 40(6) = total
250 + 300 + 240 = 790
so then he has $2,614
2614 - 790 = 1824
he has $1,824 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 :)

Answers
Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle = [tex]\frac{1}{2}\pi r^2[/tex]
⇒ area = [tex]\frac{1}{2} \times 3.14 \times 3^2[/tex]
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²

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.

Show your work.
Answers
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
