Answer:
33
Step-by-step explanation:
3q + 3j
if q= 7 and j = 4
3(7) + 3(4) = 21 + 12 = 33

<h3>Hello!</h3>
Option A is correct & here's why.
When dividing fractions, we take the first fraction and multiply it times the reciprocal of the second fraction (the second fraction flopped over)
So if we have 1/4, then its reciprocal is 4/1, or just 4.
Hence, Option A (1/5÷4) is correct.

Answer:
A
Step-by-step explanation:
-5x + 10 > -15
-5x > -25
x < 5
(switch direction of inequality sign when multiplying or dividing by a negative number)
Because x < 5, the arrow would go left (more negative) starting at 5, so the answer would be A.

Here is a more clearer version of the same question ;
29 1.2. Constructing Direct Proofs 1. Let a, b, and c be real numbers with a 0. The solutions of the quadratic equation ax 2 + bx + c = 0 are given by the quadratic formula, which states that the solutions are xi and x2. where and x2 2a 2a (a) Prove that the sum of the two solutions of the quadratic equation ax2 + bx + c = 0 is equal to -b/a . (b) Prove that the product of the two solutions of the quadratic equation ax2 + bx + c = 0 is equal to c/a.
The proving of both a) and b) has been done
