Assume f(x)=-2x+8 and g(x)=5x. what is the value of (f-g)(2)?

(f - g)(2) = -6

Step-by-step explanation:

(f - g)(2) = (-2x + 8) - 5x, where x=2

             = (-2(2) + 8) - 5(2)

             = (-4 + 8) - 10

             = 4 - 10

             = -6

(f - g)(2) = -6

the answer to your question is c.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
