Answer:
x = 1, y = -4
Step-by-step explanation:
set each equation equal:
-7x + 3 = -x - 3
-6x + 3 = -3
-6x = -6
x = 1
y = -7 + 3
y = -4
The question is the thing that needs help. What does that hanging "a leading 2" mean? And rational real coefficients? Obviously if they're rational they're gonna be real, but really.
I would say "a leading 2" means the highest power of x has a coefficient to two, which is none of the above.
The last two are of degree two, which is the lowest degree. They both have integer coefficients, so are necessarily real and rational as well.
Neither has a leading 2 as far as I can tell. The last one is monic (a leading coefficient of 1). I like monic polynomials so I'd pick that one, but that doesn't make it right.
None of the above
Answer:
4
Step-by-step explanation:
–x + 6 = 0.5x
–(4) + 6 =.5(4)=2
-x-.5x=-6
-1.5x=-6
X=4
Answer:
Option (1) increase.
Step-by-step explanation:
Let an exponential function is having common ratio = 3 ( greater than 1) and y-intercept = -1
So the function is,
Now we prepare a table for the values of x and f(x),
x -1 0 1 2
f(x) -1.67 -1 1 7
We find from the table that the values of the function are increasing with the increase in the values of x.
Therefore, Option (1) increase will be the answer.
