Solve the system of equations below.<br> x + y = 5<br> -4x – 2y = -8

mel-nik [20]

Answer:

x = -1 , y = 6

or (-1, 6)

Step-by-step explanation:

First solve for "y" in the second equation:

$-4x-2y=-8\\-4x+8=2y\\y=-2x+4$

and now, use this result as a substitution for "y" in terms of "x" in the first equation:

$x+y=5\\x+(-2x+4)=5\\x-2x+4=5\\-x=5-4\\-x=1\\x=-1$

Knowing the value of "x", now we place it in the substitution equation to find "y":

$y=-2x+4\\y=-2(-1)+4\\y=6\\$

At what point do the curves r1(t) = t, 5 − t, 48 t2 and r2(s) = 8 − s, s − 3, s2 intersect?

DerKrebs [107]

Set components equal:
$t = 8-s \\ 5-t = s-3 \\ 48 t^2 = s^2$

From this we find:
$t = 8-s \\ s = 4 \sqrt{3} t$

Substitute and solve system:
$t = \frac{8}{1+4 \sqrt{3}} = 1.009 \\ \\ s = 8-t = 8 - 1.009 = 6.991$

The point where they intersect is:
$(1.009, 5-1.009, 48(1.009)^2)$

M<A = 60°, AC =43 cm

Dmitriy789 [7]

So, theres this rule for all 30,60,90° triangles, one leg is x, the hypotenuse is 2x, and the longer leg is x(sqrt3), so ab is 2(43) so it is 86. im not sure why it says round to 2 decimal places. uh... if so, 86.00. so... that part confused me.
