Answer:
The y-intercept is -5.
Step-by-step explanation:
In algebra, "y=" and "f(x)=" is basically the same thing. You don't have to write them both. Also, 
is in slope-intercept form, which is: 
, where 
is the y-intercept. That means "-5" is the y-intercept.
Answer:
The equation for the axis of symmetry is x=1.5.
Step-by-step explanation:
It is given that a quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) .
In the given points y-coordinates are same, i.e., -8. It means both the points lie on the horizontal line y=-8.
If a quadratic function passes through two points (a,c) and (b,c), then the equation for the axis of symmetry is
According to the given points a=-5, b=8 and c=-8. Put these value in the above formula.
Therefore the equation for the axis of symmetry is x=1.5.
-4 and -5
because to get 16 to 12 you have to subtract 4 but it wants you to add so you put a negative sign infront of it.
and a negative multiply by a negative equals a positive so -3×-5=15
Answer:
-5
Step-by-step explanation:
The leading coefficient means the thing you're multiplying your highest power by. Here, your highest power of x is x^2, and that term's coeff. is -5, so the leading coefficient is -5.
Answer:
Step-by-step explanation:
Puan Rohana's income = Active income + passive income
= 2000 + 450
= RM 2450
Expenses = 1680 + 400
= RM 2080
Total expenses increased by 40%
New expenses after 40% increase = 2080 + 40% of 2080
= 2080 + (0.4 * 2080)
= 2080 + 832
= RM 2912
Puan Rohana's expenses is more than there income
