Answer:
j= (-2,2)
k=(2,1)
Step-by-step explanation:
The restrictions for the equation is that the denominator can not be zero. So the restrictions for x would be what values make the denominator zero.
7x^2 + 6x = 0
factor
x(7x + 6) = 0
multiply any number by 0 and you get 0. So either x = 0 or 7x+6 = 0
since there's a x in the numerator x/x = 1 so this will not be a restriction. Then the only restriction is:
7x+6 = 0
7x = -6
x = -6/7
m * 2 + 2 = j
Answer:
Mark is 8
Johnny is 18
Step-by-step explanation:
m * 2 = j - 2
26 - 2 = 24
24 / 3 = 8
8 * 2 + 2 = 18
The Quadratic<span> Formula uses the "a", "b", and "c" from "ax</span>2<span> + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the </span><span>quadratic equation. Therefore,
</span><span>f(x) = x2 – 5x + 6
a = 1
b = -5
c = 6</span>
