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°<br><br>Find: m∠EYL. <br><br>2)Given: m∠EYL=72°<br>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\°

<em>Find the measure of angle EYL</em>

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

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\°
