4x + 8 = 20 as you times 4 by x (which is 3) and that equals to 12, then you add 8 to 12 which equals to 20

HELP A line passes through two points with coordinates (6,-8) and (-3,7).

FromTheMoon [43]

Answer:

Step-by-step explanation:

<u>Equation of the Line</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The line passes through the points (6,-8) and (-3,7), thus:

$\displaystyle y+8=\frac{7+8}{-3-6}(x-6)$

$\displaystyle y+8=\frac{15}{-9}(x-6)$

Simplifying:

$\displaystyle y+8=-\frac{5}{3}(x-6)$

Multiplying by 3:

$3(y+8)=-5(x-6)$

$3y+24=-5x+30$

Moving all the variables to the left side:

3y + 5x = 30 - 24

3y + 5x = 6

Justify conclusion on why 2 ounces of ketchup is ok to use when eating potatoe wedges

ikadub [295]

Well you haven't really given us a question that requires a "quantifiable" answer. 2 ounces is roughly equivalent to 60 grams. 2 ounces of ketchup wouldn't be an awful lot of ketchup. I'm sure that you'd remain healthy despite eating 2 ounces of ketchup along with your potato wedges.

According to the American Heart Association, women should only have about 25 grams of sugar per day. In 100g of ketchup there would be about 22g grams of sugar. If you were to eat roughly 60g of ketchup, you'd only be digesting about 13.2 grams of sugar. Now, potato wedges could also contain sugar, but you haven't stated how many grams or kilograms of potato wedges you'd be eating, so I wouldn't be able to tell you whether your meal contains too much sugar.

we know that

The scale drawing is

$\frac{1}{4}\ in : 1\ ft$

using proportion find out the width of the great room on her plan

$\frac{(1/4)}{1}\ \frac{in}{ft}=\frac{x}{20}\ \frac{in}{ft}\\\\x=20(1/4)\\\\x=5\ in$
