Question

У=-3х+1,5 Х=1,5:2,5:4. У-? У=-4,5:0:1,5. Х-?

Answer 1

Ответ:

y=-3x+1.5 а) если x=-1,5, то y=-3*(-1.5)+1.5=6 если x=2.5, то y=-3*2.5+1.5=-6 если x=4, то y=-3*4+1.5=-10.5 б) если y=-4.5, то x=1.5+4.5/3=2 если y=0, то

Answer 2

To find the corresponding values of Y for the given values of X in the equation Y = -3X + 1.5, we substitute each X value and solve for Y:

For X = 1.5: Y = -3(1.5) + 1.5 Y = -4.5 + 1.5 Y = -3

For X = 2.5: Y = -3(2.5) + 1.5 Y = -7.5 + 1.5 Y = -6

For X = 4: Y = -3(4) + 1.5 Y = -12 + 1.5 Y = -10.5

So the corresponding values of Y for X = 1.5, 2.5, and 4 are -3, -6, and -10.5 respectively.

For the second equation Y = -4.5:0:1.5, we can find the corresponding values of X by substituting each Y value and solving for X:

For Y = -4.5: -4.5 = -3X + 1.5 -3X = -4.5 - 1.5 -3X = -6 X = -6 / -3 X = 2

For Y = 0: 0 = -3X + 1.5 -3X = -1.5 X = -1.5 / -3 X = 0.5

For Y = 1.5: 1.5 = -3X + 1.5 -3X = 1.5 - 1.5 -3X = 0 X = 0

So the corresponding values of X for Y = -4.5, 0, and 1.5 are 2, 0.5, and 0 respectively.
