Answer:
16 - y²
Step-by-step explanation:
(4 - y)(4 + y)
16 + 4y - 4y - y²
16 - y²
Answer:x+2y=6
Step-by-step explanation: Given points: (4,1) and (-4,5)
To find equation we need a slope and a point through which the line passes.
slope = (y1-y2)/(x1-x2)
= 1-5/4-(-4)
= -4/8
= -1/2
let the first point be the passing point,
eq. of a line: (y-y1)=slope(x-x1)
=(y-1)=-1/2(x-4)
=2y-2=-x+4
=x+2y=6
Answer: - 235
<u>Step-by-step explanation:</u>
f(x) = -3x² + 13x + 3
f(-7) = -3(-7)² + 13(-7) + 3
= -3(49) - 91 + 3
= -147 - 88
= -235
Answer:
300960
Step-by-step explanation:
Problem # 1
3w-10=4w+5
(3w-10) + (10-4w) = (4w+5) + (10-4w)
(3w-10) + (-4w+10) = (4w+5) + (-4w +10)
3w-10-4w+10 = 4w +5 -4w +10
3w-4w=15
-w=15
w= -15 (w is negative 15)
problem #2.
6-2t > 18
6-2t-6 > 18-6
-2t > 12
(-1) (-2t) > 12 (-1)
2t > -12
next divide by 2
2t/2 > -12/2
t > -6 (t is greater then negative 6)
