Answer:

A-B=x^2-x+1

Step-by-step explanation:

A-B=3x^2+5x-6+(-2x^2-6x+7)

Tres multiplicaciones de seis factores:una en la que el resultado sea positivo,otra en la que sea negativo,y una cuyo resultado
Free_Kalibri [48]

Answer:

Vamos a inventa tres multiplicaciones de seis factores en la que el resultado sea positivo, es decir un número mayor que cero, en la otra negativo, es decir, un número menor que cero y  por último otra multiplicación que de como resultado el  cero "0".

Primero recordemos que:

Los factores son los números que se multiplican.

Seis factores serían 6 números.

Multiplicación con resultado positivo, es decir mayor a 0:

2×3×4×2×1×5=240

Multiplicación con resultado negativo, es decir menor a 0:

-4×2×5×2×1×10= -400

Multiplicación con resultado cero:

2×4×6×7×11×0=0

Step-by-step explanation:

a walking path across a park is represented by the equation y=-2x-7. A new path will be built perpendicular to this path.The pat
jonny [76]

Answer:

The equation that represents the new path is y=(1/2)x-2

Step-by-step explanation:

step 1

Find the slope of the give line

we have

y=-2x-7

so

the slope m is equal to

m=-2

step 2

Find the slope of the perpendicular line to the given line

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal of each other

so

we have

m=-2 -----> slope of the given line

therefore

The slope of the perpendicular line is equal to

m=1/2

step 3

With m=1/2 and the point (-2,-3) find the equation of the line

y-y1=m(x-x1)

substitute

y+3=(1/2)(x+2)

y=(1/2)x+1-3

y=(1/2)x-2 -----> equation that represent the new path
