–21 + x

Explanation:

Step 1: Given expression: –4 + (–17) + x

Step 2: In the algebraic property, positive × negative = negative

So, –4 + (–17) + x = –4 – 17 + x

Step 3: Add two negative numbers, the result will be sum with minus sign

–4 – 17 + x = –21 + x

Hence,  –21 + x is the required equation.

Find the equation, in point-slope form, of the line that passes -3 and passes through the point (1,2). plz show your work.
Maslowich
Substitute the given values for the parameters in the point-slope form of the equation of a line. That form is
  y - k = m(x - h)
for point (h, k) and slope m.

You have (h, k) = (1, 2) and m=-3, so your equation is
  y - 2 = -3(x - 1)

QveST [7]

The correct answer is A. "separate but equal"

Explanation:

The excerpt presented belongs to the decision taken by Chief Justice Earl Warren (chief judge from  1943- 19539) as part of Brown v. Board of Education. In this, Chief Justice Warren declares integration is a must and the doctrine of "separate but equal" is unconstitutional as he demands "to admit to public schools on a racially nondiscriminatory basis".

Moreover, the doctrine of "separate but equal" defined by the Chief Justice as "inherently unequal" was a strategy and phrase opponents of integration used to avoid the process of integration as this implied building separated facilities for non-whites and claiming these facilities offered the same conditions. However, this doctrine still promoted discrimination as non-whites were not admitted or accepted in white schools. Moreover, in most cases the education offered and conditions were unequal. According to this, the phrase or doctrine used to drag out the process of desegregation or slow down integration is "separate but equal"
