Answer: B. (5,3)</h3>
How to get this answer:
x+y = 8 solves to y = -x+8 after isolating y. You subtract x from both sides.
Plug this into the second equation and solve for x
3x + 2y = 21
3x + 2( y ) = 21
3x + 2( -x+8 ) = 21 ... replace y with -x+8
3x - 2x + 16 = 21
x + 16 = 21
x = 21-16
x = 5
Use this to find y
y = -x+8
y = -5+8
y = 3
We have x = 5 and y = 3 pair up to get the ordered pair solution (5,3)
Answer: (b) -7/2, 6.
Step-by-step Explanation: We put x = 0; then y = 6; y-intercept of the line is (0,6).
For the slope: 4y = 24 - 14x; then, y = (-7/2)x + 6; the slope is -7/2.
-24n+49
You multiply 7 by-12n = 84n. And the 7 by -3= -21. Then 10 by 6n = 60n and 10 by 7 which is 70. When you do all the it will give you -84n-21+60n+70. The. You combine like terms which is -84 and 60( because they both have n)= -24n and 70 with -21 which is 49. So overall the answer is -24n+49
