having all the necessary or appropriate parts:
Blank 1: If y is -5 when x is 2, that means the equation here is y = -2.5x. So, if x is 8, that makes the equation y = -2.5(8), which gives you -20.
Blank 2: If y is 3 when x is 1, the equation will be y = 3x. If x is 2, that will give you y = 3(2), which is 6.
Blank 3: If y is -7 when x is -21, the equation will be x = 3y. If y is 9, that will give you x = 3(9), which is 27.
Blank 4: If y is 5 when x is 4, the equation will be y = 1.25x. If y is 18, that makes the equation 18 = 1.25x, which is 14.4.
I hope this all helped!
Answer:
Top left and bottom right
Step-by-step explanation:
you know there right triangles because the legs squared (two short sides of the triangle) add up to the hypotenuse squared (long side of triangle)
Pythagorean theorem
a²+b²=c²
a=leg, b=leg, c=hypotenuse
