Find 10% of it (just move the decimal point one spot to the left) and multiply by 4
It is 12 since 1/6=6^-1=6
implies 2*6=12
C. It is always a rational number. You cannot determine its sign without knowing the values of a and b.
Answer:y=4x+1
Step-by-step explanation: ok you are going to take your -4 over which it goes under 5 which 5-4 is 1 then your ad your x's which is 4x
Answer:
18 in^2
Step-by-step explanation:
<em>1 )The three sides of the gutter add up to 12</em>
2x+ y = 12
<em>2) Subtract 2x from both sides. </em>
y = 12 — 2x
<em>3 )Find the area of the rectangle in terms of x and simplify.</em>
Area = xy = x(12 — 2x) = -2x^2+12x = f(x)
<em>4 ) x=-b/2a</em>
<em>x co-ordinate of the vertex= -12/2(-2)=3</em>
<em>5 )Plug in 3 for x into they equation.</em>
y co-ordinate of the vertex= 12 — 2(3) = 6
<em>6 ) Plug in 3 for x and 6 for y. </em>
Area= xy = 3(6) = 18
RESULT
18 in^2
