Answer:
Number line is attached
Step-by-step explanation:
We are given inequality as
y is less than 23
so, we take all possible values that is less than 23
so, we can write interval as
For
as
now, we can draw a number line and locate y=23
and then shade left side of 23 region
that would be solution
So it cuts the y axis at -9 as it has a gradient of 0.
Therefore y=-9 is the equation, as y=mx+c, it intercepts at -9 and has a gradient of 0, therefore y=0x-9 so y=-9.

400
20
100
10
</span> i would say the answer is 10
Step-by-step explanation:
Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
Factor: Something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression. For example, the expression 7x(y+3)7x(y+3) has three factors: 77 , xx , and (y+3)(y+3) .
Coefficient: The numerical factor of a multiplication expression that contains a variable. Consider the expression in the figure above, 2x+4y−92x+4y−9 . In the first term, 2x2x , the coefficient is 22 : in the second term, 4y4y , the coefficient is 44 .
Constant: A number that cannot change its value. In the expression 2x+4y−92x+4y−9 , the term 99 is a constant.
Like Terms: Terms that contain the same variables such as 2m2m , 6m6m or 3xy3xy and 7xy7xy . If an expression has more than one constant terms, those are also like terms.
