Let the original price = x
then 76.50 = 0.90x
x = 76.50 / 0.90 = 85
Answer:
"points G and H"
Step-by-step explanation:
The vertices of the ellipse is the major axis.
<em><u /></em>
<em><u>From bottom to top edge of the curve and also from left to right edge of the curve can be vertices. Which ever's distance is greatest is the vertices.</u></em>
<em><u /></em>
Looking at J and K (top & bottom edge), we see that the length is 12 units.
Looking at G and H (left & right edge), we see that the length is 16 units.
Hence, G & H are the longer one and it is the vertices.
first answer choice is right, "points G and H"
Area of a rectangle = length * width
A = 1.6 *1.2 = 1.92 m²
The line has a positive slope. Let's look at all the slopes:
1) -3
2) -3
3) 3
4)3
Which ones are positive? That's right, 3 and 4. We don't know which equation would be the equation of the line. That's where the other information comes in.
The line intersects the y-axis at at a point that has a negative y-coordinate. Lets write the last two equations in slope-intercept form.
1) y = -3/2x - 5/2
2) y = -3/2x + 5/2
We have to graph both of the lines now. The graphs are at the very bottom. Take a look at them. In the first one, the y-intercept is a negative and in the second one, the y-intercept is positive.
The third one AKA 3x + 2y = -5 is the equation of the line. I hope this helps! Let me know if I got it wrong or if you need any more help.
The answer to this equation would be 102.50 . Hope this helps!
