Is something missing
???????????????????//
First, plug in 448 for y:
448=7x+294
Secondly, subtract 294 from both sides to isolate x:
154=7x
Divide both sides by 7:
22=x
Refine:
x=22
The answer is D)22
Answer:
D) a = - 5/2
Step-by-step explanation:
2x -5y - 7 = 0
5y = 2x - 7
y = 2/5 x - 7
the slope of this line is therefore 2/5 (factor of x).
the perpendicular slope is then (exchange y and x and flip the sign) -5/2, which is then a and the factor of x.
Answer:
LCM of 3, 5, and 11 is 165.
Step-by-step explanation:
B.
It can first be factored by splitting to:
(x + 1)(x^2 +4)
And (x^2 + 4) splits to x +/- 2i
