One x-intercept for a parabola is at the point (-2,0).

BARSIC [14]

You can find the x intercept by setting y to 0 and factor the equation.

0=2x^3+3x-2
0=(2x-1)(x+2)

We can make this equation =0 if x is -2 and 1/2.

So the x intercepts are (-2,0) and (0.5,0)

Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cube

kvasek [131]

Answer:

Step-by-step explanation:

Tomas learned that

$a^3+b^3=(a+b)(a^2-ab+b^2)$

If $a=2x,\ b=y$ , then

$a^3+b^3\\ \\=(2x)^3+y^3\\ \\=((2x)+y)((2x)^2-(2x)y+y^2)\\ \\=(2x+y)(4x^2-2xy+y^2)$

Solve the equation for y.

gayaneshka [121]

Answer: C

Step-by-step explanation:

$2x+5y=5$

$\mathrm{Subtract\:}2x\mathrm{\:from\:both\:sides}$

$2x+5y-2x=5-2x$

$\mathrm{Simplify}$

$5y=5-2x$

$\mathrm{Divide\:both\:sides\:by\:}5$

$\frac{5y}{5}=\frac{5}{5}-\frac{2x}{5}$

$\mathrm{Simplify}$

$\bf{y=-\frac{2}{5}x + 1}$
