Given the following inverse variation find the missing value: (5,-8) (20, y) find the missing value

forsale [732]

This answer is pretty simple. you see (5,-8) and (20,y). well the 20 is 4 times the 5 on the x value so multiply the y value by 4 to get your answer which Y=-32 in the 2nd corrdenants.

Question 2(Multiple Choice Worth 4 points) (08.02)A pair of equations is shown below. x + y = 5 y = one halfx + 2 If the two equ

8_murik_8 [283]

Answer:

$(2,3)$

Step-by-step explanation:

The first equation is $x+y=5$

The second equation is $y=\frac{1}{2}x+2$

When we graph these two equations, <em>they will meet at a point which represent the solution of the two equations</em>.

We can solve the two equations simultaneously to determine their point of intersection.

Let us substitute the second equation into the first equation to get;

$x+\frac{1}{2}x+2=5$

Multiply through by 2 to get;

$2x+x+4=10$

Group similar terms to obtain;

$2x+x=10-4$

Simplify;

$3x=6$

Divide both sides by 3;

$\Rightarrow x=2$

Put $x=2$ into the second equation;

$y=\frac{1}{2}(2)+2$

$\Rightarrow y=1+2$

$\Rightarrow y=3$

Therefore the graphs of the two functions intersect at (2,3)

See graph in attachment.

Answer:

∠ ABC = 81° , ∠ FEC = 90°

Step-by-step explanation:

Since AB ≅ BC then Δ ABC is isosceles.

The median BE is therefore

The angle bisector of ∠ ABC and

BE bisects AC at right angles.

Thus

∠ ABE = ∠ CBE = 40° 30' , then

∠ ABC = 2 × 40° 30' = 81°

Since BE is perpendicular to AC then

∠ FEC = 90°
