Given -16 = m over 5 -18; prove m=10

1 answer:

3 0

$- 16 = \frac{m}{5} - 18 \\ = > - 16 = \frac{m - 18 \times 5}{5} \\ = > -16 \times 5 = m - 90 \\ = > - 80 = m - 90 \\ = > - 80 + 90 = m \\ = > 10 = m \\ = > m = 10$
Hence provided

Answer:

Step-by-step explanation:

Givens:

4 hours total time

48 miles total distance

X = 7W? + 4w - 6<br> Y =w2 - 11w +13<br> X-Y<br> Your answer should be a polynomial in standard fom.

svp [43]

Answer: $w^2-22w+19$

Step-by-step explanation:

$X=7w+4w-6\\Y=w^2-11w+13\\$

$(7w+4w-6)-(w^2-11w+13)\\7w+4w-6-w^2+11w-13\\(7w+4w+11w)+(-6-13)-w^2\\22w-19-w^2\\-w^2+22w-19$

Normally we wouldn't have our square variable be negative, so in order to get rid of that negative sign without changing the equation is by multiplying by -1

$-1(-w^2+22w-19)\\=w^2-22w+19$
