Answer:top one is a
second one is c
nuber 3 is c
4 is b
Step-by-step explanation:
Answer:
1. x >= 4
2. x /= -4
3. The first one
4. The second one
Step-by-step explanation:
1. Since the bolded arrow is pointing to numbers greater than 4, we can tell that x is greater than 4. The dot on the number 4 is colored, meaning that four is included, thus x is greater than or equal to 4.
2. Since the bolded areas are on every point on the graph except -4, we can tell that x is every number but -4, thus x is not equal to -4.
3. The sign "<" indicates that x is less than 3. This eliminates the second option. Since there is no equal to sign, the dot isn't colored, thus, the first one.
4. The sign "<=" indicates that x is less than or equal to -1, eliminating the third option. Since it is equal to, the dot should be colored, thus, the second one.

-2 is greater than -2 1/2 not less than
1 is greater than -.5 but -1 can't be greater than -.5
-3.4 is greater than -4 but 3.4 can't be less than -4
Explanation:
-2<-2 1/2 because -2 1/2 is a negative and it’s 1/2 more negative making it less than 2 not greater than.
-2> -2 1/2 is correct because like I said in the last one -2 1/2 is less than 2
1> -0.5 is correct because -0.5 is a negative and 1 is a positive
-1> -0.5 is incorrect because -1 is further in the negatives than -0.5 think about it like this if I owe a friend a dollar or 50 cents which one is? The 50 cents
3.4<-4 is incorrect because 3.4 is a positive and -4 is a negative.

For this equation the easiest thing to start with ratios:
16:4 (scale of 4 due to 4 x 4 being = to 16)
For the y-2 to find y you first will put 8/4 (your scaling back), so 2 so 4-2 would be 2 which makes that equal to y.
Knowing that 8 is the size on the one side these are equal on the top so x-3 had to equal 8, so 11-3=8 so...
x=11
y=2
4x4=16
y-2
8/4
4-2
2=y
x =11

question
how would you solve this problem
the ratio of *name*'s age to his brother's is 2:3. In ten years, the ratio would be 4:5. How old is *name* and his brother now and in 10 years?
also how would you solve it if the ratio changed to something different, ex: 1:3 to 3:5 in 10 years
Answers
Answer:
*name* is 10 years old now and brother is 15 years now
In 10 years they would be 20 and 25 respectively
Step-by-step explanation:
Let x = *name*'s age now
let y = brother's age now
The first relationship is that the ratio of their ages now is 2:3 or, in fraction form 2/3
That means x/y = 2/3
Cross multiply => 3x = 2y =>
3x - 2y = 0 [1]
10 years from now x would become x + 10 years, y would become y + 10 years and the new ratio is 4/5
So (x + 10)/(y+10 = 4/5
Cross-multiply
5(x + 10) = 4(y + 10)
5x + 50 = 4y + 40
Subtract 4y from both sides
5x + 50 -4y = 40
and subtract 50 from both sides:
5x - 4y = 40 - 50
5x -4y = -10 [2]
Eliminate y terms by multiplying [1] by 2 and subtracting [1] from that
[1] x 2
=> 2(3x - 2y) = 2 x 0
=> 6x - 4y = 0 [3]
[3] - [2]
6x - 4y - (5x -4y) = 0 - (-10)
6x - 4y -5x + 4y = 10
x = 10
Using equation [1] we get
x/y = 2/3
=> 10/y = 2/3
10 x 3/2 = y
5 x 3 = y
y = 15
So their ages are 10 and 15 now.
In 10 years they would be 20 and 25
If the ratios change we would have a different set of equations to solve for
For example if the current ratio is 1/3
Then we would get x/y = 1/3
or 3x - y = 0 [4]
and if 10 years from now the ratio is 3/5 then
(x + 10)/(y + 10) = 3/5
=> 5(x+10) = 3(y + 10)
=> 5x + 50 = 3y + 30
=> 5x - 3y = -20 [5]
And we would solve these equations to get x and y in a similar mannter
FYI the answers would be
x = 5, y = 15

First step, make ratios:
Pages: time
Sheldon: 9 pages: 15 minutes
Betty: 18 pages: 60 minutes (1 hour)
To find how long it would be for 360 you divide:
9/15 is 0.6 pages: 1 minute and 18/60 is 0.3 pages per minute
When you make the table here would be the equation:
y=.06x for Sheldon and y=.3 for betty (plug in times and create a table)
