Y= 1/2x-4 and y= -2x-9 what is the solution of equations

azamat

Answer:

(x,y)=(-2,-5)

Step-by-step explanation:

y=1/2x-4

y=-2x-9

(y=) 1/2x-4=-2x-9

1/2x +2x=-9+4

1/2x +4/2x=-5

5/2x=-5

5x=-5*2

5x=-10

x=-2

y=-2x-9=-2*(-2)-9=4-9=-5

(x,y)=(-2,-5)

There is a parallelogram ABCD with diagonals AC and BD. The diagonals AC and BD intersects each other at point E. Side AB is con

grandymaker [24]

Answer:

SAS theorem

Step-by-step explanation:

Given

$\square ABCD$

$\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD$

$\angle BAC = \angle DCA$

Required

Which theorem shows △ABE ≅ △CDE.

From the question, we understand that:

AC and BD intersects at E.

This implies that:

$\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC$

and

$\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED$

So, the congruent sides and angles of △ABE and △CDE are:

$\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD$ ---- S

$\angle BAC = \angle DCA$ ---- A

$\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED$ or $\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC$ --- S

Hence, the theorem that compares both triangles is the SAS theorem

Suppose g (x) is increasing and concave up everywhere and g(A)=7, gprime(A)=13, h=.01

rewona [7]

First we need a point (x,y) : (A, 7)
Now slope (from f'(A)) = 15 
Next, the equation (using point slope formula) 

y - 7 = 15 (x -A) 
y = 15 (x - A) + 7 

Now in the x spot we put 'A-.01' 
y = 15 ( A - .01 - A) +7= 15(-.01) +7 = -.15+ 7 = 6.85
hope this helps
