X²/25 + y²/100 =1
4x²/100+ y²/100 =1
4x²+y²=100
y²=100- 4x²
If x=0, y²= 100, y = ±10
c{(0,-10),(0,10)}
If y=0, 4x²= 100, x²=25, x=±5
d {(-5,0),(5,0)}
Answer:
2 and -1/2
Step-by-step explanation:
perpendicular lines have slopes that have opposite signs and are reciprocals
Answer:
Which polynomial is prime?
7x2 – 35x + 2x – 10
9x3 + 11x2 + 3x – 33
10x3 – 15x2 + 8x – 12
12x4 + 42x2 + 4x2 + 14
Step-by-step explanation:
Which polynomial is prime?
7x2 – 35x + 2x – 10
9x3 + 11x2 + 3x – 33
10x3 – 15x2 + 8x – 12
12x4 + 42x2 + 4x2 + 14 SO IT IS RIGHT
Answer:
6108795
Step-by-step explanation:
To obtain the number of ways the committee can be selected :
4 teachers from the 12 teachers available and 3 students from the 43 students available
Using combinatorics :
12C4 * 43C3
recall :
nCr = n! ÷ (n - r)!r!
Using calculator :
12C4 = 495
43C3 = 12341
12C4 * 43C3
495 * 12341
= 6108795
Use order of operations (PENDAS)to divide 1/4 by 5/6 (remember to use the reciprocal of the second number). Than find GCF with that number you have now and 4/9 to get your answer.
