Answer:
10x^4-15x^3+17x^2-13x+17
Step-by-step explanation:
P-2Q
Replace P and Q with the given values,
4x^4-3x^3+x^2-5x+11-(2(-3x^4+6x^3-8x^2+4x-3)
4x^4-3x^3+x^2-5x+11-(-6x^4+12x^3-16x^2+8x-6)
4x^4-3x^3+x^2-5x+11+6x^4-12x^3+16x^2-8x+6
10x^4-15x^3+17x^2-13x+17
Answer: 102 children and 41 adults swam at the pool that day.
Step-by-step explanation:
Let x represent the number of children that swam at the public pool that day.
Let y represent the number of adult that swam at the public pool that day.
On that certain hot summer's day, 143 people used the public swimming pool. It means that
x + y = 143
The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $219.75. It means that
1.25x + 2.25y = 219.75- - - - - - - - -1
Substituting x = 143 - y into equation 1, it becomes
1.25(143 - y) + 2.25y = 219.75
178.75 - 1.25y + 2.25y = 219.75
- 1.25y + 2.25y = 219.75 - 178.75
y = 41
x = 143 - y = 143 - 41
x = 102
Answer:
i got you just tell me the question
Step-by-step explanation:
C = 1.6b
c + b = 442
1.6b + b = 442
2.6b = 442
b = 442 / 2.6
b = 170 <== Boston
c = 1.6b
c = 1.6(170)
c = 272 <== Colorado Springs
So remember that the distance formula is 
.
1.
Distance between (4,-5) and (4,-2) is 3 units.
2.
Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
