A number has 2,5 and 7 as its prime factors. what are the four smallest values it and take​
MA_775_DIABLO [31]

Answer:

  70, 140, 280, 350

Step-by-step explanation:

Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.

Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...

So, the four smallest numbers with prime factors of 2, 5, and 7 are ...

  70 = 2·5·7

  140 = 2²·5·7

  280 = 2³·5·7

  350 = 2·5²·7

Determine the equation of the line with slope 3 that passes through the point M(1, 2).
Mandarinka [93]

Answer:

Step-by-step explanation:

We are given the slope along with an (x, y) coordinate with which to write the equation.  You could use this info in the slope-intercept form and solve for b, or you could use this info in the point-slope form and solve it for y.  Trust me when I tell you that either one will get you the correct equation.  Promise!  I used the point-slope form, just because.  ; )

y - 2 = 3(x - 1) and

y - 2 = 3x - 3 and

y = 3x - 1 OR in standard form, we will put the x and y terms on the same side of the equals sign, separated from the constant:

-3x + y = -1.  But if we get picky and do not like to lead with negatives, we could change ALL the signs to their opposites (which is the same as multiplying the whole thing by a -1) to get

3x - y = 1 which is the third choice down.
