I believe it is 3
Step-by-step explanation:
Answer:
Greatest Common Factor: integer or variable multiplied by other integers or variables that creat a resultin product. factor x factor = product
difference of squares binomial: an expression where two perfect square terms are being subtracteda² - b² = (a+b)(a-b)quadratic: from "quad" meaning square, because the variable gets squared (like x2).
discriminant: tells you about the roots of a quadratic
general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation
zero: a value that gives you 0 for a function
x-intercept: where the graph crosses the x-axis
y-intercept: where the graph crosses the y-axis
extraneous: a solution that does not work
parabola: the graph of a quadratic
vertex: the turning point of the parabola
axis: line of reflection
translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)

Answer:
a= -2 and b=3
Step-by-step explanation:
Step 1) Solve the first equation for a:
a + 3b = 7
a + 3b - 3b = 7 - 3b
a + 0 = 7 - 3b
a = 7 - 3b
Step 2) Substitute(7 - 3b) for a in a second equation and solve for b:
2a = b - 7 becomes:
2(7 - 3b) = b-7
(2 multi.7) - (2 multi.3b)= b-7
14 - 6b = b - 7
14 + 7 - 6b + 6b = b + 6b = b + 6b - 7 +7
21 - 0 = 1b + 6b - 0
21=(1 + 6)b
21 = 7b
21
/7 = 7b/7
3 = 7b/7
3 = b
b = 3
Step 3) Substitute 3 for b in the solution to the first equation at the end of Step 1 and calculate a
:
a = 7 - 3b becomes:
a = 7 − (
3 ⋅ 3)
a = 7 −
9
a = −
2
