How I got my answer before was substitution!
Answer:
(0,-2); The y-intercept is y=-2.
Step-by-step explanation:
Recall that the y-intercept is simply (0, y). In other words, we simply need to plug zero into the equation to acquire the y.
Thus:
10/10 and 5/5 are like fractions
Answer:
Two sequences have the formulae 3n-1 and 7n+2 . A new sequences is formed by the number which appear in both of these sequences.
Step-by-step explanation:
To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
