The domain refers to values on the X-axis, and as you can see there are arrows on the orange line, meaning it goes on "forever". This is all real numbers.
The y-axis (range) has the line go through at -2. The line is pointing up, which means all the numbers are greater than -2, or could be equal to -2.

Answers
Answer: Hello mate!
The notation:
a < b
means that the number b is bigger than the number a, and the notation:
a ≤ b
means that the number b is bigger or equal than the number a.
"all real numbers y that are less than 4"
this is written as:
y < 4
"all real numbers that are greater than 9"
this is written as:
y > 9
then, the situation can be written as:
y <4 and y >9, which means that the right answer is option C.
The Correct answer would be C... A would only be correct if they said equal to or less/greater than.

Answer:
A. 4.7 cm
Step-by-step explanation:
where the rectangles are similar, the ratios of the sides must be similar
Given that One has a length of 14 cm and a width of 9 cm, and the other has a width of 3 cm
let the length of the other rectangle be L
14/9 = L/3
L = (14 × 3)/9
= 14/3
= 4.66cm
≈ 4.7cm
The right option is A. 4.7 cm
Let's x the length of the second rectangle:
x/14=3/9==>x=14/3==>x=4.666666......
Answer A
3x − 4y = −18
12x + 4y = −12
15x = −30
8x + 4y = −4
14x = −10
6x − 8y = −36
−6y = −42
6x − y = −15
3y = 9

Answer:
4/5
Step-by-step explanation:
{(2/5) / (1/2)} ×1
= (2/5)÷(1/2)
= 2/5×2/1
= 4/5
Answer:
4/5
Step-by-step explanation:
Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.
Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.
