Y=2x and x+3y=-14 substitution to solve each system of equations

Sergeeva-Olga [200]

You can use the substitution method.
You substitute the first equation to the second equation to get the value of x.
x + 3y = -14
x + 3(2x) = -14
x + 6x = -14
7x = -14
x = -14/7 = -2

Substitute the value of x to the first equation.
y = 2(-2) = 4

B) If A x B = {(-1, 1), (-1, 2), (2, 1), (2, 2), (3, 1), (3, 2)}. Find A x A and B x B.

Oduvanchick [21]

hope this helps!

Step-by-step explanation:

A = {-1, 2, 3}

B = {1,2}

AxA = {(-1,-1) (-1,2) (-1,3) (2,-1) (2,2) (2,3) (3,-1) (3,2) (3,3)}

BxB = {(1,1) (1,2) (2,1) (2,2)}

1) Given: mLHE=84° Find: m∠EYL. 2)Given: m∠EYL=72° Find: m arc EHL, m arc LVE

SCORPION-xisa [38]

Answer:

Part 1) The measure of angle EYL is $96\°$

Part 2) The measure of arc EHL is $108\°$ and the measure of arc LVE is $252\°$

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

Part 1)

Let

x------> the measure of arc LHE

y----> the measure of arc LVE

we know that

$x+y=360\°$

$x=84\°$

Find the value of y

$y=360\°-84\°=276\°$

Find the measure of angle EYL

$m$

substitute the values

$m$

Part 2)

Let

x------> the measure of arc EHL

y----> the measure of arc LVE

we know that

$x+y=360\°$

$x=360\°-y$ -----> equation A

$m$

substitute

$72\°=\frac{1}{2} (y-x)$

$144\°=(y-x)$

$x=y-144\°$ --------> equation B

equate equation A and equation B and solve for y

$360\°-y=y-144\°$

$2y=360\°+144\°$

$2y=504\°$

$y=252\°$

Find the value of x

$x=252\°-144\°=108\°$

therefore

The measure of arc EHL is $108\°$

The measure of arc LVE is $252\°$
