Answer:
D is incorrect
Step-by-step explanation: A is correct because there are 12 cars and 7 trucks. B is correct because there are 7 trucks and 12 cars. C is correct because there are 12 cars and 19 total vehicles(7+12=19). D is incorrect because while there are 7 trucks, there are not 12 vehicles in TOTAL.
The Pythagorean Theorem applies to all right angle triangles. Therefore if you substitute the numbers, it should work out.
Pythagorean Theorem: a^2+b^2=c^2
Does 8^2+15^2=17^2?
8 squared plus 15 squared is 289. 17 squared is 289. Therefore #1 is a right triangle.
5^2+8^2=11^2
89 doesn’t equal 121 so #2 is not a right angle triangle

❇Answer: y=-5x+5
❇Explanation:
First I'll write down the points given:
(-2,15)➡1st point=(x1,y1)
(2,-5)➡ 2nd point=(x2,y2)
(6,-25)➡ 3rd point=(x3,y3)
(10,-45)➡4th point=(x4,y4)
Calculating slope using 1st and 2nd points:
slope= (y2-y1)/(x2-x1)
=(-5-15)/[2-(-2)]
=-20/4
=-5
Calculating slope using 3rd and 4th points:
slope= (y4-y3)/(x4-x3)
=[-45-(-25)]/(10-6)
=-20/4
=-5
Since slope of first two points and last two points are equal, all of these points lie on same line whose equation can be given in slope-intercept form as,
↪y=mx+c {m is slope}
↪y=-5x+c➡Eqn(1)
Let (0,c) be any point cutting y-axis making
y-intercept=c
Lets take 1st point and (0,c) and apply slope formula,
slope=(c-15)/[0-(-2)]
↪-5=(c-15)/2
↪c-15=-10
↪c=15-10
↪c=5
Put value of c in Eqn(1),
↪y=-5x+5
