Answer:
a = 2
b = 1
c = 1
Step-by-step explanation:
The quadratic equation, 2x² + x + 1 = 0, is expressed in the standard form as ax² + bx + c, where a ≠ 0.
Thus,
a = 2
b = 1 (1 * x = x)
c = 1

Answer:
y - 7 = 1/2(x - 7)
Step-by-step explanation:
Point slope form is y - y1 = m (x - x1)
So find m = y2 - y1/ x2 - x1, so m = -1 - 7 / -9 - 7, m = -8 / -16 so m = 1/2
Then sub your (7,7) so y - 7 = 1/2(x - 7)

Answer: B
Step-by-step explanation:
Solve x2 + 8x − 3 = 0 using the completing-the-square method.
x = four plus or minus the square root of three
x = negative four plus or minus the square root of three
x = four plus or minus the square root of nineteen
x = negative four plus or minus the square root of nineteen
Answer:
Step-by-step explanation:
x^2+8x-3=0 (move constant to other side by adding 3 to each side)
x^2+8x=3 (halve thr linear coefficient, square it and add to each side, (8/2)^2=16)
x^2+8x+16=3+16 (now the left side is a perfect square)
(x+4)^2=19 (now take the square root of each side)
x+4=+-(19^(1/2)) (finally subtract the constant to isolate x by itself)
x= -4+-(19^(1/2))
x=negative four plus or minus the square root of nineteen
Answer:
D) x = negative four plus or minus the square root of nineteen

I need to figure out how many solutions does the system of equations below have.
y=6/7x-8 and y=7/9x+10/9
Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So
[tex]\frac{6x}{7} - 8 = \frac{7x}{9} + \frac{10}{9}[/tex]
[tex]\frac{6x}{7} - \frac{7x}{9} = \frac{10}{9} + 8[/tex]
[tex]\frac{54x - 49x}{63} = \frac{10}{9} + \frac{72}{9}[/tex]
[tex]\frac{5x}{63} = \frac{82}{9}[/tex]
[tex]45x = 63*82[/tex]
Both a and b are different of 0, so the system has one solution.

Step-by-step explanation:
ok the 3000 does NOW MATTER they ask about the norm. so 2500 ÷ 6.50$
=384.61 :)
Answer:
when the doubled the pair of sandals manufactured=3000-2500
=500
the amount spend on manufacturing running shoes=,2500-500
=2000
number of sandals made=500//2.50
(without doubling) =200
number of running shoes =2000/4
=500
Dara pinkston Recorded her house and expenses for a month of August mortgage payment was 347.90Insurance $17 Texas $84 electricity $64.40 phone service $33.50 fuel $98.25 water $17.44 in repairs $79.87 .Her monthly take-home pay is 2150 what’s her total money coast?
Answer:
the total monthly cost is $742.36
Step-by-step explanation:
The computation of the total monthly cost is shown below:
= Mortgage payment + insurance + taxes + electricity + phone service + fuel + water + repairs
= $347.90 + $17 + $84 + $64.40 + $33.50 + $98.25 + $17.44 + $79.87
= $742.36
Hence, the total monthly cost is $742.36

19. The National Health and Nutrition Survey reported that 39% of adults in the United States
have hypertension (high blood pressure). A sample of 24 adults is studied.
A. What is the probability that exactly 17 of them have hypertension? ____________
B. What is the probability that at least 10 of them have hypertension? ____________
C. What is the probability that at most 12 of them have hypertension? ____________
D. Would it be unusual if more than 8 had hypertension? Write your answer by using a
complete sentence or two
Answer:
A. P(x=17) = 0.00121
B. P(x=10) = 0.15768
C. P(x=12)=0.0888
D. No , x can take any value more than 8
complete sentence or two
Step-by-step explanation:
Here n= 24 ; p= 0.39 ; q = 1-0.39= 0.71
Applying binomial probability distribution
P(X=x) = nCx p^x q^n-x
Part A.
P(x=17) = 24c17 p ^17 q^24-17
P(x=17) = 0.00121510493
Part B.
P(x=10) = 24c10 p ^10 q^24-10
P(x=10) = 0.1576877824
Part C.
P(x=12) = 24c12 p ^12 q^24-12
P(x=12)=0.08887201897
D. The random variable X can obviously take on anyone of the (n+1) integer value 0,1,23,-------,n in the binomial probability distribution

Answer:
The blanks in order for the bottom row are 8, 9. The blanks for the top row is 6.
Step-by-step explanation:
It is counting by 1's starting at 5 for the bottom row and starting at 0 counting by 1's in the top row.
Answer:
in order from left to right, 8, 9, 6
Step-by-step explanation:
Since he already wrote 5 pages and will write 1 more every hour, the top row (# of hours) + 5 will equal the bottom row (pages written). 3+5=8, 4+5=9, and 6+5=11, so from left to right, it's
8, 9, 6

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 100 miles per hour. The westbound train
travels at 90 miles per hour. How long will it take for the two trains to be 304 miles apart? ( this is timed plz someone help)
Solving for the elapsed time
distance traveled = (speed of first train + speed of second train) * elapsed time
280 miles = (95 mph + 105 mph) * elapsed time
280 miles = 200 mph * elapsed time
elapsed time = 280 miles / 200 mph
elapsed time = 1.4 hours
elapsed time = 1 hour and 24 minutes
It will take 1 hour and 24 minutes for the two trains to be 280 miles apart.
