Find the equation, in point-slope form, of the line that passes -3 and passes through the point (1,2). plz show your work.

Maslowich

Substitute the given values for the parameters in the point-slope form of the equation of a line. That form is
y - k = m(x - h)
for point (h, k) and slope m.

You have (h, k) = (1, 2) and m=-3, so your equation is
y - 2 = -3(x - 1)

Finger [1]

Answer:

1) $4.51$ × $10^-3$

2) .00632

Step-by-step explanation:

1.Which of the following is equivalent to 0.00451?

= $\frac{451}{100000}$

= $\frac{4.51}{1000}$

= $\frac{4.51}{10^3}$

= $4.51$ × $10^-3$

Therefore the answer is (a)

Which of the following is equivalent to 6.32 x 10-*3?

In order to find the answer to this question you can just put the notation into standard form which means they will be equivalent to each other.

The exponent is negative so you move to the left:

$6.32=.00632$

= $.00632$

Therefore 6.32*10^-3 is equivalent too (c) .00632

topjm [15]

Answer:

30 sets of model B
20 sets of model A

Step-by-step explanation:

To maximize profit, the greatest possible number of the most profitable item should be manufactured. Remaining capacity should be used for the less-profitable item.

Up to 30 of model B, which has the highest profit, can be made each day. The remaining amount (20 sets) of the daily capacity of 50 sets should be used to make model A sets.
