So solving this you would change the greater than sign to an equal sign 3+4n=31 then you would solve this by subtracting 3 from 31 which gives you 28 so then you have 4n=28 then you divide each side by 4 to get n by itself which gives you n=7 so then you would change back the sign to n>7
the other problem you would do the same thing so 2n-6=18 the first step you would do is add 6 to both sides, 2n=12 then divide both sides by 2 n= 6 then change back the sign n<6 (less than or equal to) make sure to add the dash under the last problem i just couldn’t add it to this on my phone.
Answer:
(16, 0) should be right.
Step-by-step explanation:
Well, I used to do the math, but after using Acellus a while, I found Symbolab.
It's suuuper handy with Algebra. I highly recommend.
How I found this intercept was enter:
<em>intercept</em><em> </em>-2x+8y=-32
and bam it lists you all intercepts!
Answer:
3.934 = 3.634; hope this helps........
Step-by-step explanation:
Solve:
Multiply the numbers
5.62 ⋅ 0.7 = 2.68 ⋅ 1.35
3.934 = 2.68 ⋅ 1.35
Multiply the numbers
3.934 = 2.68 ⋅ 1.35
3.934 = 3.618
Result
3.934 = 3.618
The input is a contradiction: it has no solutions
Answer: Walk through writing a general formula for the midpoint between two points. ... I believe you would simply find the differences in x and y from the midpoint to the one ... How would you solve a problem in which you do not know point B but are given ... the line y=x and the curve y=4x-x^2 intersect at the point p and q.
Step-by-step explanation:
Answer: Laundry = $2
Dishes= $1
Step-by-step explanation:
Let the amount paid for doing laundry be x
Let the amount paid for doing dishes be y.
Based on the information in the question, this can be formed in an equation as:
5x + 8y = 18 ..... i
4x + 6y = 14 ...... ii
Multiply equation i by 4
Multiply equation ii by 5
20x + 32y = 72 ...... iii
20x + 30y = 70 ...... iv
Subtract iv from iii
2y = 2
y = 2/2 = 1
Dishes cost $1
Since 5x + 8y = 18
5x + 8(1) = 18
5x = 18 - 8
5x = 10
x = 2
Laundry cost $2
