Answer:

A

Step-by-step explanation:

since both equations express y in terms of x we can equate the right sides

x + 7 = - 2x + 19 ( add 2x to both sides )

3x + 7 = 19 ( subtract 7 from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

substitute x = 4 into either of the 2 equations for y

y = x + 7 ⇒ y = 4 + 7 = 11

solution is (4, 11 )

An artist designed a badge for a school club. Figure ABCD on the coordinate grid below shows the shape of the badge.
dedylja [7]

Answer:

(8, 4)

Step-by-step explanation:

<em>AD is enlarged to JM</em>

<em>AD² = 2² + 1² = 4 + 1 =5</em>

<em>AD =  √5</em>

then you plug in JM

<em>JM² = 6² + 3² = 36 + 9 = 45</em>

<em>JM = √45 = 3 √5</em>

<em>so if </em>

<em>JM=3 AD</em>

then

<em>ML= 3 DC </em>

<em>then you add</em>

<em>5+3=8</em>

the coordinates for point L are (8, 4)

Answer:

Right angle triangle goes to 15m, 8m, 17m

Step-by-step explanation:

Square root of 15^2 + 8^2 is 17

(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)

So, 10m ,11m ,15m isn't a right angle triangle

Hope this helps!
