The answer would be the top right graph where none of the lines intersect since it shows that there is no possible real solutions for the system if none of the lines intersect on a certain point.

Remember: If the lines intersect, there is a solution; if the lines do not intersect, there is no solution; if the lines fall on the same line, or the equations are equivalent, then the solution is all real numbers.

Alrighty mate.

I reckon the answer as hmmm...I'd say<u><em> D</em></u>. All ya gotta do is just cover up the opposite variable and solve for the intercept yar lookin' for.

I hope I helped mate.

Dilution Problem

LUCKY_DIMON [66]

Answer:

76.7 liters

Step-by-step explanation:

You have ...

C1×V1 = C2×V2

so ...

V2 = V1×(C1/C2) = (115 L)×(14/21) = 76 2/3 L

V2 ≈ 76.7 L

Write the equation of a circle given the center (-4, 4) and raduis r = 5.

Len [333]

Answer:

A) $(x+4)^2+(y-4)^2=25$

Step-by-step explanation:

The equation of a circle is $(x-h)^2+(y-k)^2=r^2$ where $(h,k)$ is the center and $r$ is the radius. If $(h,k)\rightarrow(-4,4)$ and $r=5$ , then:

$(x-h)^2+(y-k)^2=r^2\\\\(x-(-4))^2+(y-4)^2=5^2\\\\(x+4)^2+(y-4)^2=25$

Therefore, the equation of the circle is $(x+4)^2+(y-4)^2=25$

Can someone help? Thanks :D

Answer:

$y\leq -x+4$

Step-by-step explanation:

The first thing that we can do is look at the equation of the line and then worry about the inequality afterwards.

This line has a y-intercept of 4 and a slope of -1.

This means that the equation of this line would be $y=-x+4$

Now that we have the equation of the line, we just need to determine which inequality sign to use.

As the shaded region is BELOW the line, we will use a less than (<) sign.

As the line is fully shaded, I can only assume that it is meant to include the line, which would mean that $y\leq -x+4$ would be the equation for this inequality.
