Let the number of girls=4x
then number of boys=7x
7x-4x=15
3x=15
x=15/3=5
boys=5*7=35
girls=4*5=20
number of students=35+20=55
The value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞ of the number line will satisfy this condition.
<h3>What is a number line?</h3>
A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.
The value of x that will satisfy this condition can be found by simplifying the given inequality. Therefore, The given inequality can be simplified as,
4x + 1 - 1 ≥ -8
4x ≥ -8
x ≥ -2
Hence, the value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞ of the number line will satisfy this condition.

Answer:
1. Reduction.
2. (0, 0)
3. 1/3
Step-by-step explanation:
1. This is a reduction becuase the image gets smaller.
2. The point of dilation is the origin because that is what they both share and it is where is shrinks with. Sorry if that sounded really weird it is how I like to think about it.
3. The scale factor is 1/3 because the size shrinks 3 times.
Answer:
do you need an equation for this because if so it is
y - 2 = 7 (x - 4)
Step-by-step explanation:
you just use y - y = m (x - x)
