Step-by-step explanation:
The graphs of x=2(y-4) and x=5(y-4) are shown below.
How does the graph of x=2(y-4) compare with the graph of x=5(y-4)
A. The graph of x=2(y-4) crosses the y-axis lower than the graph of x=5(y-4)
B. The graph of x=2(y-4) has greater slope than the graph of x=5(y-4)
C. The graph of x=5(y-4) has greater slope than the graph of x=2(y-4)
D. The graph of x=2(y-4) crosses the y-axis higher than the graph of x=5(y-4)
Answer:
B is the correct answer
Step-by-step explanation:
because x=2y-8 is same as y=1/2 x+4 x=5y-20 is the same as y=1/5 x+4 slope of the first is 1/2 slope of the second is 1/5 so 1/2>1/5there y intercept are the same which is 4
The graph of x=2(y-4) has greater slope than the graph of x=5(y-4), the correct option is B.
What is the standard equation of a line?The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
The equation of the line is
x=2(y-4)
x=5(y-4)
y = (1/2)x +4
y = (1/5)x +4
The slope is (1/2) and (1/5),
(1/2) > (1/5)

What is half of 9 minutes and 28 seconds
One minute contains 60 seconds. The half of 9 minutes and 28 seconds in time is 4 minutes and 44 seconds.
How are minutes and seconds related?A minute can be expressed in terms of seconds by the relation:
[tex]1 \: \rm min. = 60 \: \rm sec.[/tex]
9 minutes = [tex]9 \times 60 = 540 \: \rm sec.[/tex]
Thus, 9 mintues and 28 seconds = 540 + 28 = 568 seconds.
Its half would be:
[tex]\dfrac{568}{2} = 284 \: \rm sec.[/tex]
Dividing it by 60 to convert it back to minute and second form, we get:
Quotient = 4, remainder = 44
The remainder is still not divided by 60, so its in minutes.
But the quotient is the divided part of 284 by 60, so its in minutes.
Thus, 284 seconds = 4 mintues + 44 seconds.
Thus, the half of 9 minutes and 28 seconds in time is 4 minutes and 44 seconds.

An Olympic diver is competing for a metal. His height in meters above the water can be modeled by the function
f (x)= -4.9x^2+9.8x+14.7f(x)=−4.9x +9.8x+14.7
where is is the time in seconds after he begins the dive.
After how many seconds does he reach the water?
What domain makes sense for this scenario?
Answer:
-4.9x²+75x=-4.9x+50x+38
75x=50x+38
25x=38
x=1.52
1.52 -4.9(1.52)²+75(1.52)=102.67904≈102.7 meters
Double check: -4.9(1.52)²+50(1.52)+38=102.67904≈102.7. Yes.

8 – 6 (x – 4) = 2x – 2 (4x – 5) + 22
Answer:
Here
Step-by-step explanation:
Let's solve your equation step-by-step.
8−6(x−4)=2x−2(4x−5)+22
Step 1: Simplify both sides of the equation.
8−6(x−4)=2x−2(4x−5)+22
8+(−6)(x)+(−6)(−4)=2x+(−2)(4x)+(−2)(−5)+22(Distribute)
8+−6x+24=2x+−8x+10+22
(−6x)+(8+24)=(2x+−8x)+(10+22)(Combine Like Terms)
−6x+32=−6x+32
−6x+32=−6x+32
Step 2: Add 6x to both sides.
−6x+32+6x=−6x+32+6x
32=32
Step 3: Subtract 32 from both sides.
32−32=32−32

Start with 2. Add 6 to each term to get the following term. What is the 6th term of the sequence?
Answer:
32
Step-by-step explanation:
We can either add all the terms.
2+6=8
2,8
8+6=14
2,8,14
14+6=20
2,8,14,20
20+6=6
2,8,14,20,26
26+6=32
2,8,14,20,26,32
The Sixth term is 32
or We can multiply 6 times 5 (30) and add 2, which would give us 32.
The reasoning behind this is that we are adding six five times (so six times five) and we are also adding the first term (2).
If A1

BRAINLIEST TO ANYONE
Answer:
25
Step-by-step explanation:
a1 = 9
a2 = a1 + 4
a2 = 9 + 4
a2 = 13
a3 = a2 + 4
a3 = 13 + 4
a3 = 17
a4 = 21
a5 = 21 + 4
a5 = 25
This can more easily be done by using this formula
L = a1 + (n - 1) * d
a1 = 9
n = 5
d = 4
L = 9 + (5 -1)*4
L = 9 + 4*4
L = 9 + 16
L = 25

PLEASE HELP 8 ml of a 80% acid solution was mixed with 12 ml of a 20% acid solution. What is the percentage of acid in the new solution?
Answer:
44%
Step-by-step explanation:
So you have 2 bottles. One bottle is 8ml and is 80% acid. the other is 12 ml and is 20% acid.
This means there's 6.4 ml of acid in bottle 1(8*0.8) and 2.4 ml of acid in the other one(12*0.2).
The total amount of liquid is 8+12 = 20
The total amount of acid is 6.4+2.4 = 8.8
Percentage of acid in the new solution is 8.8/20 = 0.44 = 44%
Roxie is picking out some movies to rent, and she is primarily interested in horror films and foreign films. She has narrowed down her selections to 20 horror films and 8 foreign films. How many different combinations of 3 movies can she rent if she wants at least two horror films?
Answer:
She has 2,660 combinations
Step-by-step explanation:
Here, we want to calculate the number of different combinations of 3 movies that can be rented
The condition is at least two horror movies
What this means is that she can select 2 or 3 horror movies
if two horror movies, then 1 foreign film
The combination is as follows;
20 C 2 * 8 C 1
= 190 * 8 = 1,520
If she is selecting 3 horror movies, then no foreign film will be selected
Number of ways this can be done is;
20 C 3 = 1,140
So the
number of different combinations would be;
1,140 + 1,520 = 2.660
