The lines represented by the equations 25y
gogolik [260]

Answer:

C: The Same Line

Step-by-step explanation:

So to start we need to first know what makes lines parallel or perpendicular. Two parallel lines will have the same slope, but different y-intercepts because we know they never cross. Two perpendicular lines will have opposite-reciprocal slopes, because we know that they intersect at a right angle.

Then, we  need to know the slope-intercept form of an equation. The slope intercept form is y=mx+b where m is the slope of the line and b is the y-intercept. We can see that neither equation is in this form, so we have to convert it.

Starting with the first, (I assume despite the typo) we have 25y+10x= 200

So we need to isolate the y from everything else.

First, we'll subtract 10x from both sides of the equal sign to get 25y=-10x+200

Second, we'll divide both sides by 25 to get y=-\frac{2}{5} x+8

This means that -\frac{2}{5} is the slope and 8 is the y-intercept of the first line.

Now onto the second we have 5y+2x=40 so we're going to follow the same steps to isolate y.

First, we'll subtract 2x from both sides to get 5y=-2x+40

Second, we'll divide both sides by 5 to get y=-\frac{2}{5}x +8

This means that -\frac{2}{5} is the slope and 8 is the y-intercept of the second line.

Since both of the lines have a slope -\frac{2}{5} we know that they are parallel, so we need to check to check if they're the same by looking at the y-intercept. We can see that 8 is the y-intercept of both lines, so they would be the same line.

How many oz. of a metal containing 40%
RideAnS [48]

Answer:

3 oz

Step-by-step explanation:

Let x represent the number of oz. of the medal with 40% gold:

Set up an equation and solve for x:

0.4x + 7(0.9) = 0.75(x + 7)

0.4x + 6.3 = 0.75x + 5.25

6.3 = 0.35x + 5.25

1.05 = 0.35x

3 = x

So, you will need 3 oz. of the metal with 40% gold

barxatty [35]

Answer:

C

Step-by-step explanation:

The ratio is given as \frac{12}{9} = \frac{4}{3} in simplest form
