A certain drug is made from only two ingredients, there are five milliliters of part a and four milliliters of part b. If a chem

patriot [66]

You will have to divide 353 millimeters by 4:

353 ÷ 4 = 88.25

now we have to multiply 88.25 by 9 (5+4), the total millimeters of only one portion of this drug

88.25 x 9 = 794.25

So he will make 794.25 millimeters of drug (that is if he has the part a too)

(If you should round 88.25 to 88, the answer would be 88 x 9 = 792)

P what equation in slope-intercept form represents the line that passes through the points (3,5) and (-9,2)

ivanzaharov [21]

Answer:

$y =\frac{1}{5}x+\frac{22}{5}$

Step-by-step explanation:

To write the equation of a line, use the slope formula to first find the slope.

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{3--9}=\frac{3}{3+12}=\frac{3}{15}=\frac{1}{5}$

Substitute m=1/5 and the point (3,5) into point slope formula.

$y-y_1 = m(x-x_1)\\y-5=\frac{1}{5}(x-3)\\y-5=\frac{1}{5}x -\frac{3}{5}\\y =\frac{1}{5}x+\frac{22}{5}$
