Answer:
Her first mistake was in Step 2. She added 0.2 to each term instead of multiplying by 0.2.
Step-by-step explanation:
CORRECT WAY:
0.2(4+1.4y - 2.1)
0.8 + 0.28y - 0.42
0.8 - 0.42 + 0.28y
0.38 + 0.28y
WHAT TAMARA DID:
0.2(4+1.4y - 2.1)
How she got 4.2: 0.2 + 4 = 4.2
How she got 1.6y: 0.2 + 1.4y = 1.6y
How she got -1.9: 0.2 + -2.1 = -1.9
WHAT SHE DID HERE IS WRONG. REMEMBER WHEN IT IS __( ______) IT MEANS THAT YOU NEED TO MULTIPLE NUMBER OUTSIDE THE PARATNESS TO EVERY NUMBER THAT IS INSIDE THE PARATNESS.
Answer: y = (-1/2)x+1
----------------------------------------------
Explanation:
D = Midpoint of A and B
D = (x,y)
x = [(xCoord of A)+(xCoord of B)]/2
x = [(-4)+(4)]/2
x = 0/2
x = 0
y = [(yCoord of A)+(yCoord of B)]/2
y = [(-2)+(4)]/2
y = 2/2
y = 1
So the midpoint of AB is D = (x,y) = (0,1)
The median for point C will go through the points D = (0,1) and C = (18,-8)
Let's find the slope of line DC
m = (y2-y1)/(x2-x1)
m = (-8-1)/(18-0)
m = -9/18
m = -1/2
Then use the slope m and one of the points D or C to find the y intercept b
I'm going to use the coordinates of point D
y = m*x+b
1 = (-1/2)*(0)+b
1 = 0+b
b = 1
So the equation of line DC is y = (-1/2)x+1, which contains the median that goes through point C
Answer:
The function is even because f(x) = f(−x).
Step-by-step explanation:
we know that
An even function is one for which
f
(−x)=f(x) for all x in its domain.
An odd function is one for which
f(
−x)
=−f(x) for all x in its domain
In this problem we have
so
therefore
f
(x)=f(-x) for all x in its domain.
Is a even function
