I'm not good with any math that is above per algebra sorry.
If each painting takes 3 hours, and he has to do 8 then he would spend 24 hours doing all 8 portraits
Given:
The point, (4, -3)
The line,
To find an equation in slope-intercept form for the line that passes through (4,-3) and is parallel to the given line:
The slope of the line is,
Since the given line is parallel to the new line, so the slope will be same for the both.
Using the point-slope formula,
Substitute the point and slope we get,
Hence, the equation in slope-intercept form for the line is,
$55-$35=20
$20 divide by $0.25=80 miles.
therefore denise can drive the car for 1day 80 miles to stay within her budget
