Answer:
F and B (as far as I can see).
Step-by-step explanation:
First, let's simplify the equation. You can easily do this by dividing by -4.
-4x < 20
/-4 /-4
x > -5
REMEMBER- Whenever dividing or multiplying a negative number with inequalities, the sign flips!!
On A, we can see that it has a negative symbol, but if we were to divide that, the sign would flip, making -5 greater than x. That's not what we want.
On B, the 20 is negative instead of the 4. Does this change anything?
4x > -20
/4 /4
x > -5
Nope! It still simplifies to what we had at the beginning so it works!
C and D are slightly confusing me because, well, I don't really see how it's relevant to anything so... It doesn't even have a inequality symbol so I don't know lol.
E is wrong because we need the 5 to be positive.
F is obviously right compared to our first answer.
Answer: F, b, a

Please answer number 9 and here is the translation “ Luis already wrote 5 pages of a science report. He plans to write 1 page every hour. He fills in the missing values in the input and output table.” Thank you also giving brainliest
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
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

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)

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.

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

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

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.
