Answer:
Step-by-step explanation:
If a = 0, f(a) = f(0) = 0 + 0 + 7 = 7;
If a = 1, f(1) = 3(1^2) + 2(1) + 7 = 12;
and so on. Normally an 'a' value would be given as part of this problem.
Actually, the value of f(a) is given and is f(a) = 3a^2+2a+7 for input value a.
Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
Answer:
D) X = 11
Step-by-step explanation:
Solve for x
5x + 2 = 59
subtract 2 from both sides
5x = 57
divide both sides by 5
x = 57/5
this answer would be closest to x = 11 (11* 5 = 55)
5 1/2 = 5 5/10 and 1 1/5 = 1 2/10. 5 5/10 + 1 2/10=
6 7/10
