;)
Answer:
(8,5)
Step-by-step explanation:
5x - 2y = 30
coordinates are (x,y) so you plug in 8 for x and solve for y
5(8) - 2y = 30
40 - 2y = 30
subtract 40 from both sides to isolate y
-2y = -10
divide both sides by -2 to isolate y
y = 5
To know if p = -1 is a possible solution to <span>6(p – 4) = -30p, plug in -1 for p and see if the equation is true.
</span><span>6(p – 4) = -30p
</span><span>6(-1 – 4) = -30(-1)
</span>6(-1 – 4) = -30(-1)<span>
Solve the parentheses.
-1 - 4 = -5
</span>6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30
-30 = 30
This is not true, so p = -1 is NOT a possible solution for the <span>equation 6(p – 4) = -30p.
Hope this helps!</span>
Simplify (2+5-10) and then it's -3 and then (7x)(-3) = -21
