F(x) = -9x + 2 and g(x) = -9x + 6, find (f - g)(7)

Lemur [1.5K]

Answer:

I think there is an error in the question because

(f-g) = -4

(f-g) (7) = NO SOLUTION

Step-by-step explanation:

$f(x) = -9x + 2 \\g(x) = -9x + 6\\(f - g)(7)\\(f - g) = -9x + 2 - (-9x+6)\\(f - g) = -9x +2 +9x-6\\(f - g) = -9x +9x+2-6\\(f - g) = -4$

The ratio of girls to boys in he 6th grade is 6 to 7. How many girls are there if there are 364 total students

inn [45]

If the ratio is 6:7 the students should divide nicely into 6+7=13 parts. Six of those parts are girls, seven of those parts are boys.

364 / 13 = 28

So 6 × 28 = 168 girls

Answer: 168

Check:

7 × 28 = 196 boys

168 + 196 = 364, good
