the answer is 12.8 because
both of these equations added together make a straight line, or 180 degrees
so we have to put them together: 7x+8x-12=180
and we just solve for x
Answer:
The rate of change or slope m = -50
Step-by-step explanation:
The slope-intercept form of the line equation

where
- m is the rate of change or slope
Given that there is $500 in Holly's bank account.
Thus, the y-intercept b = 500
It is stated that she takes out $50 from her account each month but doesn't put money back in.
It means the rate of change or slope is decreasing.
Thus, the rate of change or slope m = -50
<u>EXTRA BONUS!</u>
We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form

y = -50x + 500
Here:
The slope m = -50
The y-intercept = 500
WXY is a acute angle
YXZ is a acute angle as well
A. =4^(-11/3)*4^(2/3)
=4^(-9/3)
=4^(-3)
=1/64
