Question 1 Alia and Meera were simplifying the expression (2x² + x) + 2(-x² + x) and obtained different
answers. Who is correct and why?
Meera
=(2x² + x) + 2(-x² + x)
=(2x² + x) + (-x? + x) + (-x2 + x)
= (2x2 - x - x?) + (x + x + x)
= 3x
Alia
= (2x² + x) + 2(-x2 + x)
= (2x? <) - 2x + x
= 2x

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

you divide them and then you get the answer i took this class this year

step-by-step explanation:

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.

p.p.s brainliest would really
