Answer: I think the answer is 15.
A = 1100
m = a - 220
m = 1100 - 220
m = 880
Answer:
x^2 14x + 49
Step-by-step explanation:
Use F.O.I.L method
FIRST: x * x = x^2
OUTSIDE: 7*x
INSIDE: 7*x
LAST: 7*7= 49
x^2 + 7x + 7x + 49
x^2 14x + 49
Answer:
x = 4
Step-by-step explanation:
You begin by making what is inside the brackets = 0. In other words you will somehow get 0 * brackets + 3 = 3
x - 4 = 0
x - 4 + 4 = 0 + 4
x = 4. When you make x = 4, the inside of the brackets = 0
1/2 * 0 = 0
So you are left with
3 = 0 + 3
and x has been made = 4
Do what's in the brackets before anything else.
Hello:
2x+3y=8
y =(-2/3)x+8/3 (the slope is : (-2/3) )
<span>an equation of the line through (-1,4) and perpendicular to 2x+3y=8</span>
<span> is : y = ax+b
the slope is a : a×(-2/3) = -1......(
perpendicular to a line with a slope of -2/3)
a = 3/2 y=(3/2)x+b
the line that passes through (-1, 4) :4 =
(3/2)(-1)+b
b =11/2
the equation is : y = (3/2)x+11/2</span>
