Answer:

Step-by-step explanation:

Hello There!

y = -5x^2 + 8x +4

where y = height of ball and x = seconds after ball was thrown

The plus 4 is the y intercept and because y equals height of ball the 4 would represent the height that the ball was thrown at

$\\ \sf\longmapsto 256x^2y^2-x^2y^2+49y^2x^2$

$\\ \sf\longmapsto 256x^2y^2-x^2y^2+49x^2y^2$

$\\ \sf\longmapsto (256-1+49)x^2y^2$

Help please 6th grade math

viva [34]

Answer:

A and C

Step-by-step explanation:

By letting x = 0 she is eliminating the terms in x , rather than simplifying

9x - 3x - 4 ← collect like terms

= 6x - 4

12x - 4 ← already in simplest form

5x + x - 4 ← collect like terms

= 6x - 4

Thus A and C are equivalent expressions
