Answer:
200 times
Step-by-step explanation:
45 + 0.4x = 75 + 0.25x
45 + 0.4x - 45 = 75 + 0.25x -45
0.4x = 30 + 0.25x
0.4x - 0.25 x = 30 + 0.25x - 0.25x
0.15x = 30
Multiply by 100 on each side to make it easier.
15x = 3000
x = 200
Answer: option C.
Step-by-step explanation:
Given a quadratic function of the form , if the coefficient <em>a</em> is less than zero, then the function is opened upward.
The options A is not opened upwards, then it is not the answer.
Then the given equation can be written as:
This function is equal to the parent function, shifted 4 units down.
Therefore, the graph that you are looking for must be a parabola that is opened upwards and has its vertex in the point (0,-4).
Then, the correct option is C. And the solution is:
It is just 18 :)It is just 18 :)
20*25= 500
that is how many there should be
500-5=495
that is how many they set up
Answer:
x-intercept= -3
y-intercept= -2
m(slope)= (-2/3)
equation= y=(-2/3)x -2
Step-by-step explanation:
x-intercept: where the line hits the x-axis
y-intercept: where the line hits the y-axis
m(slope)= (y2-y1)/(x2-x1)
using the intercepts, (0,-2) and (-3,0)
(-2-0)/(0-(-3))
-2/(0+3)
-2/3
equation:
y=mx+b
we don't know b so to solve for it we can use any point as "x" and "y" but I am going to use (0,-2)
y= -2
m(slope) = -2/3
x= 0
b=?
-2=(-2/3)*0 +b
-2= 0+b
-2=b
so y=(-2/3)x -2
