<u>ANSWER</u>
A. (4,12)
<u>EXPLANATION</u>
The equations are:
and
To eliminate a variable we make the coefficients of that variable the same in both equations.
It is easier to eliminate x.
We multiply the first equation by 2 to get:
We add equations (2) and (3).
Divide both sides by 23
Put x=4 into equation (1).
The solution is (4,12)
a. -7 is your answer dear.
Step-by-step explanation:
Ur complete Question is like -245/35 = -7
Brigitte is shorter than 5 feet. (Brigitte's height=h)
We write this in inequality form
Brigitte's height is h
So 'h' is shorter than 5 feet
Shorter means less than so we use < symbol. We should not use = symbol because height is shorter than 5 not equal to 5.
Suppose if it is given ' height is more than 5 feet ' then we use greater than symbol (>)
h is less than 5 feet
h < 5
Inequality is h < 5
we have
we know that
The volume of a cube is equal to
where
b is the length side of a cube
Using a graph tool------> find the roots of the polynomial
see the attached figure
x=4
so
therefore
<u>The answer is</u>
the length side of a cube is equal to (x-4)
