Simple the answer is: n=14
Answer:
A) 8x + 9y = −3
B) 6x + 7y = 1
We multiply A) by -(6/8)
A) -6x -6.75y = 2.25 then we add this to equation B
B) 6x + 7y = 1
.25y = 3.25
y = 13
and x = -15
Step-by-step explanation:
Answer:
a=4
Step-by-step explanation:
ax − 4 = 2y
We need to get the equation is slope intercept form y= mx+b.
Lets solve for y
Divide each side by 2
a/2 x - 4/2 = 2y/2
a/2 x -2 = y
or y=a/2 x -2
The slope is a/2 and the y intercept is -2
We want a slope of 2 so a/2 =2
a/2=2
Multiply each side by 2
a/2 * 2 =2*2
a =4
Answer:
f(x) approaches positive infinity.
g(x) approaches negative infinity.
the y-intercept of f(x) is less than the y-intercept of g(x).
Step-by-step explanation:
the highest power of x in f(x) is 3, and it has a positive sign. so, the bigger x the more the x³ part will dominate.
therefore, with x going to positive infinity, also f(x) goes to positive infinity.
the graph of g(x) clearly dives down never to come back up or flatten out. so, with x going to positive infinity, g(x) goes to negative infinity.
the y-intercept of f(x) = f(0).
that means the functional value when x=0.
so, for x=0 this means
y = 2×0³ - 3×0² + 5×0 + 7 = 7
the graph of g(x) shows that g(0) is 8.
so f(0) is less than g(0).
