Answer:
100 square inches
Step-by-step explanation:
Dimension of each of the ten pictures= 4 inches by 6 inches
Area of one of the pictures=4*6=24 Square Inch.
Total Area of the 10 pictures=24*10=240 Square Inches.
Dimension of the Poster Board=20 inches by 17 inches.
Area of the Poster Board=20*17=340 Square Inches.
Area not covered by the pictures=340-240=100 Square Inches
Therefore, 100 square inches of the green background will show after the pictures are mounted.
Answer:
the following points would make a trapezoid
2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
Answer:
The equation of line is shown below.
Step-by-step explanation:
The equation of line is

It is the point slope form of a line, therefore the slope of the line is
and the line passing through (4,-1).
Rewrite the above equation in slope intercept form.



The point slope form of a line is

Where m is the slope and b is y-intercept.
Therefore the slope of the line is
and the y-intercept of the line is
.
Slope is defined as

Since the slope is negative, therefore the run of the line is considered on the left side. The line rise by 3 and run by 5, therefore we will add 7 in y and subtract 5 from x.
The y-intercept is
.

Therefore we have three points (4,-1), (-5,4.4) and (0,1.4). Plot the point on the coordinate plane and connect them be a straight line.
Step-by-step explanation:
he get one hour=15$
he get bonus end of the month=85$
- total 685$- bonus 85$=600$
- 600$÷one hour 15$= 40 hours
