Answer:
y = -4/5 x - 6
Step-by-step explanation:
First turn both standard form equations to slope-intercept form.
4x + 5y = 10 -3x - 4y = 24
-4x -4x +3x +3x
<u>5y</u> = <u>-4x + </u><u>10</u> <u>-4y</u> = <u>3x + 24</u>
5 5 -4 -4
y = -4/5 x + 2. y = -3/4 x - 6
Now that you have each in slope-intercept form, we can begin the magic.
So we know that this line's y-intercept will be -6.
Not to mention since it's parallel, that means it will share the same slope as y = -4/5 x + 2, which the slope is -4/5. All together it will be
y = -4/5 x - 6. Now we can graph the line's to see if we we're right. (Look at graphs, attached above⤴⤴⤴) As you can see they are parallel.
Hope this helped :)
Answer: Yes, Sally is correct.
Step-by-step explanation: Both of Sally's statements are mathematically correct, because to begin with the total of the sum of angles in a triangle is always equal to 180 degrees. An acute angle is less than 90 degrees and that means we can calculate three acute angles from a triangle.
Also an obtuse angle is greater than 90 degrees, but less than 180 degrees. That means, a triangle cannot have more than one obtuse angle. If for instance a triangle has an angle measuring 91 degrees (obtuse angle), then the other two angles will be divided between the remainder which is 89 degrees.
Also a triangle can only have one right angle (which measures 90 degrees). This implies that, in a right angled triangle, there cannot be another 90 degree angle, because that would reduce the shape to two angles only (which is not possible).
A triangle can contain at least two acute angles (and at most three acute angles) and all three angles in either case must add up to 180 degrees.
