An algebraic expression that always has the same value regardless of the value of the variable is called an identity. <span>An identity, in
mathematics, is a relation between A and B that would result to an equality of
the two. It should be expressed as A = B wherein both values has some variables
that would produce the same value no matter what will be the values used for
the two functions. An example would be
</span>
5(2x+3)=9x+15+x
Assuming x would be 1, when we simplify the equation above, both sides would have the same value of 25.
5(2(1)+3)=9(1)+15+1
25 = 25
Answer:
what is the qestion
Step-by-step explanation:
Answer:
The equation of the line is;
y + 4 = 3(x + 4)
Step-by-step explanation:
The general equation of a line is;
y = mx + b
where m is the slope and b is the y-intercept
To get the equation, let us look at the given intercepts
We have the intercepts at the point (0,5) and (-2,-1)
We have the slope of the line as follows;
m = (y2-y1)/(x2-x1) = (-1-5)/(-2-0) = -6/-2 = 3
So we have the equation as;
y = 3x + b
recall, we have the y-intercept as 5
so the complete equation is;
y = 3x + 5
Now, we can rewrite this as;
y+ 4 = 3(x + 3)
Answer:
Money Ivan gets extra = 120 - 30 (or 3x) = 90
Step-by-step explanation:
Ivan = 4x
Tanya = 1x
Total = 150
4x + x = 150
5x = 150 ; x = 150 / 5 = 30
Ivan = 4x = 120
Tanya = 1x = 30
Money Ivan gets extra = 120 - 30 (or 3x) = 90
Answer:
1/2
Step-by-step explanation:
There are 3 numbers greater than 2: 3, 4, 5, and 6. There are 6 numbers, so it is 3/6=1/2.
