Answer: B

Step-by-step explanation:

You have two points, use the tilt formula (y2-y1)/(x2-x1)=m. The resultad is -3. And use the straight line formula y-y1=m(x-x1).

In this case, use the first point (1,2)

y-2=-3(x-1)

y-2=-3x+3

y=-3x+5

lapo4ka [179]

$\bf \cfrac{a}{b}\div \cfrac{c}{d}\implies \cfrac{a}{b}\cdot \cfrac{ d}{c}\qquad therefore \qquad \cfrac{3}{5}\div \cfrac{3}{15}\implies \cfrac{3}{5}\cdot \cfrac{15}{3}\implies \cfrac{3}{3}\cdot \cfrac{15}{5}\implies 3$

Which of the following numbers are written correctly in expanded form? Select TWO that apply.

ivolga24 [154]

Answer:

C is correct, D might be correct if you forgot 000 at the end of the question.

Step-by-step explanation:

005 = 5x1 so A is incorrect

945 = 9x100 + 4x10 + 5x1 so B is incorrect

15.859 = 1x10 + 5x1 + 8/10 + 5/100 + 9/1000 + so C is correct

973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect
