Answer:
<u>C) −2x − 2y + 17</u>
Step-by-step explanation (PEMDAS):
First, we do <u>3 (y + 5)</u> because of the parenthesis:
6x − 5y + 2 − 8x + 3y + 15
Since there are no exponents, multiplication ,or division, we will add and subtract. But we have to make sure we <u>combine like terms</u>. X with X's, Y with Y's and constants with constants. And ALWAYS go from left to right
6x − 5y + 2 − 8x + 3y + 15
<u>−2x</u> − 5y + 2 + 3y + 15
−2x <u>− 2y</u> + 2 + 15
<em>−2x − 2y</em><em> </em><em>+ </em><em><u>17</u></em><em>.</em>
C.) 30h = 180
Since you already have your base all you have to do is find the height
BxH= A
30xH = 180
Answer:
To find the x intercept substitute 0 for y and solve for x. To find the y intercept substitute 0 for x and solve for y.
X intercept: (-2,0)
Y intercept: (0,5/2)
im not sure if you looking for the X and Y intercept for the second equation but if you are the
X intercept: (5/2,0)
Y intercept: (0,-5)
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
