Answer:

c) (-5, -7)

Step-by-step explanation:

In a parallelogram, the midpoints of the diagonals are the same point. This means ...

(R+T)/2 = (S+U)/2

R +T -S = U

(-6 +4 -3, -3 -1 -3) = U = (-5, -7)

Answer:

infinite

Step-by-step explanation:

Let the linear equation in two variables be ax+by+c=0

Put values

$\\ \sf\longmapsto 1a+3b+c=0$

$\\ \sf\longmapsto a+3b+c$

Hence for any values it has infinite number of solutions .

Answer: $30$

Step-by-step explanation:

Given

$k(x)=2x+3$

$M(x)=3x^2+7x-10$

$M\left(k(x)\right)$ is given by replacing the $x$ by $k(x)$ from the $M(x)$

$\Rightarrow M\left(k(x)\right)=3(2x+3)^2+7(2x+3)-10\\\Rightarrow M\left(k(x)\right)=3(4x^2+9+12x)+14x+21-10\\\Rightarrow M\left(k(x)\right)=12x^2+50x+38$

Now, $M\left(k(-4)\right)$ is

$\Rightarrow M\left(k(-4)\right)=12(-4)^2+50(-4)+38\\\Rightarrow M\left(k(-4)\right)=192-200+38\\\Rightarrow M\left(k(-4)\right)=30$

How to find x and the equation for it

vladimir2022 [97]

Answer:

Step-by-step explanation:To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis. That point is the x intercept.
