First translate words to symbols
The word is translates to =
The word multiplied translates to *
The letter n is a variable, do nothing with it
90=123n
P.S. If its multiplication and there is something to multiply with a variable
Dont do 123 * n or n * 123
Write it 123n (its the proper way)
Answer:
In general, quadratic equations have two x-intercepts. But sometimes it happens that a quadratic eqution has one x-intercept or no interepts. That's why we should fully analyze this equation:
Given the following equation: y=3x^2 + 7 + m
If y=0, then:
3x^2 + 7 + m = 0 ⇒ x^2 = (-m-7)/3
Then 
± 
Given that we can take the square root of a negative number, the only way this equation has two x-intercepts is if m<-7.
Summarizing:
The equation: y=3x^2 + 7 + m has two x-intercepts only if m is less than -7. If m equals -7, the equation has only one x-intercept, and finally, if m is greater than -7, the equation has NO x-intercepts.
The value of a for the given equation is a=(r-q)/g.
The given equation is ga+q=r.
We need to find the value of a from the given equation.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, ga+q=r can be solved for a as follows:
⇒ga=r-q
⇒a=(r-q)/g
Therefore, the value of a for the given equation is a=(r-q)/g.
