On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The
number b varies directly with the number a. For example b = 2 when a =-23. Which equation represents this direct
variation between a and b?
b=-a
b=-a
b-a=0
bl-a) = 0

step-by-step explanation:

a thesis statement is a topic it is not a fact or a question

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

pi or 3.14159265359 is an irratinal decimal
