Write a subtraction expression for the number line model. B -6 -4 - 2 2 4. 6 & 10 Which subtraction expression does the number line model show? OA. -2-7 OB. 7-2 O C. - 7-2 OD. 2 - 7

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
