Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.

Tip:

With these kinds of equations focus on the x and y values

Same exact values = parallel

x and y values are swapped = perpendicular

anything else = neither

Suppose that you want to mix two coffees in order to obtain 100 pounds of a blend. If x represents the number of pounds of coffe

Fantom [35]

Answer:

The required expression that represents the number of pound of coffees B is $100-x$

Step-by-step explanation:

Consider the provided information.

You want to mix two coffees in order to obtain 100 pounds of a blend.

Let x represents the number of pounds of coffee A and y represents the number of pounds of coffee B.

The obtained weight is 100 pounds.

$x+y=100$

$y=100-x$

Hence, the required expression that represents the number of pound of coffees B is $100-x$

For the point P (-17,25) and Q(-10,30), fins the distance d(P,Q) and the coordinates of the midpoint M of the segment PQ.

Nonamiya [84]

Answer:

Distance = 8.6

M = (-13.5,27.5)

Step-by-step explanation:

Distance = $\sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2$

= $\sqrt{(-10_ }- (-17)_{ })^2 + (30_{ }- 25_{ })^2$

= $\sqrt{(-10_{ }+ 17_{ })^2 + 5^2_$

= $\sqrt{7^2+5^2}$

= $\sqrt{49+25}$

= $\sqrt{74}$

= 8.6

Midpoint = $(\frac{x_{2}+x_{1}}{2};\frac{y_{2}+y_{1}}{2})$

= (-10+(-17)) ÷ 2 ; (30+25) ÷ 2

= -27 ÷2 ; 55 ÷ 2

= -13.5, 27.5

Suppose the solution x=6 increases to x=9 and the left side of the equation stays the same. How would the right side need to cha

hoa [83]

Given that solution for some equation is x=6

Now they want to change x=6 into x=9.

Notice that all equations contans equal sign (=) because both side values are always same.

So if by any chance you want to change value of one side then you must change value on other side too

like we see that 6 changed to 9 by adding 3 on right side then we must add 3 on the left side too

so we get:

x=6

x+3=6+3

x+3=9

Now question says that the left side of the equation stays the same. That is possible only if we move +3 to the right side from the left side so we can write;

x=9-3
