Which ordered pair (a, b) is the solution to the following system of equations?

Kamila [148]

Answer:

(-13, -4)

Step-by-step explanation:

It is about as easy to try the solutions as it is to find them from scratch.

However, we can determine which one it is by adding twice the second equation to the first.

(-2a +3b) +2(a -4b) = (14) +2(3)

-5b = 20

b = -4 . . . . . . matches the first choice

Find CD if C(0,3) and D(4,7)

weeeeeb [17]

$C(0,3) \\
x_1=0 \\
y_1=3 \\ \\
D(4,7) \\
x_2=4 \\
y_2=7 \\ \\
\overset{\underline{\ \ \ \ }}{CD} =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(4-0)^2+(7-3)^2}= \\
=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{16 \times 2}=4\sqrt{2} \\ \\
\boxed{\overset{\underline{\ \ \ \ }}{CD} = 4\sqrt{2}}$
