Answer:
an equation
Step-by-step explanation:
A mathematical statement that two expressions are equal is called an equation.
The word "equation" comes from the same root as "equality"... so is two sides of an expression are of equal values, they form an equation, like A = B.
When both sides of a statement are not equal to each other, that is an inequality, meaning NOT equal, like A > B.
Step-by-step explanation:
4x² - 3x - 2 = 0
0 = 4x² - 3x - 2
0 = 16x - 3x - 2
0 = 13 x -
Answer:
The equation of the parabola is given to be : y = -x² + 36
So, the airplane will cut the rainbow if the graph of the equation of airplane intersects the graph of rainbow.
Now, to find the equation of airplane :
The points through which airplane passes are : (1,0) and (0,2)
⇒ Equation : 2x + y = 2
This equation will intersect the parabola at exactly two points.
And the points are the solution of these two equation :
(-4.916,11.832) and (6.916,-11.832)
The required table is :
x -4.916 11.832
y 6.916 -11.832
Answer:
false i think
Step-by-step explanation:
The last one: x/2=45; x = 90
the problem says: half of a number is 45.
let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45
to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides
x/2 • 2 = 45 • 2
x = 90
hope this helped!
