Answer: 49
Step-by-step explanation:
The missing constant term in the perfect square is 49.
x^2 + 14x + 49
We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

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
Answers
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:
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)
Answers
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.

Answer:
a = 2
b = 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

(-9,-1) x= -9, y= -1

-8= -16m multiply by -1
8=16m
m=8/16
m=1/2
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)

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

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
Answers
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
