No, it isn't a right triangle.
Use rise over run to find slope. If you don't know what that is, its y2-y1/x2-x1. Y2 is 125, Y1 is 25, X2 is 5, and X1 is 1. You then plug the numbers in, 125-25=100. 5-1=4. then you divide 100/4, in which you get 25. So you times 25 by 3, getting 75.
Slope of 2y = x + 5:-
This is y = 0.5 x + 2.5 in slope intercept form so its slope = 0.5
Slope of the line perpendicular to it = -1 / 0.5 = -2
it passes through (2 , 1) so we have
y- 1 = -2(x - 2)
y = -2x + 4 + 1
The answer is y = -2x + 5
Answer:
195
Step-by-step explanation:
4 drinks = 1.5 * 4 = 6.
3 sandwiches = 2 * 3 = 6
2 treats = 1 * 2 = 2
$6+$6+$2+$25 = 39
Multiply by 5 for each kid
39*5=195
