Let the second no. be x
-3x = 21 → x = 21/-3 → x = -7
Answer:
It is the y=intercept
Step-by-step explanation:
Because if there is no x-value and there is a Y-value, y-intercept
Answer:
7
Step-by-step explanation:
When you match the form
... ax² + bx + c = 0
to the equation
... 3x² + 5x + 7 = 0
it is reasonable to conclude that ...
... a = 3, b = 5, c = 7.
_____
The question presumes you are familiar with the form
... ax² +bx +c = 0
which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.
Answer:
Step-by-step explanation:
1. 48 x 5= 240
2. James minutes- 48 Alisa's- 240
3. 48 + 240 = 288
Equation: 48 + 5 (48)= 288
