Step-by-step explanation:
a)x + 4 + 2x +5
= x + 2x + 4 + 5
<h3>= <u>3x + 9</u></h3><h3 /><h3>b)10x - 3x + 7</h3><h3>=7x + 7</h3><h3 /><h3>c)5x + 6y + 2xy + 4x - 2y</h3><h3>=5x + 4x + 6y - 2y + 2xy</h3><h3>=9x + 4y + 2xy</h3><h3>c)7t + 2r - 3t + r</h3><h3>=7t - 3t + 2r + r</h3><h3>=4t + 3r</h3><h3 /><h3>d)14 + 11p - 12</h3><h3>=14 - 12 + 11p</h3><h3>=2 + 11p</h3><h3 /><h3>e)8q - 3t + 4q + 9</h3><h3>=8q + 4q + 3t + 9</h3><h3>=12q + 3t + 9</h3><h3 />
Answer:
dy/dx = 9x²+2
dy = (9x²+2) dx
dy/dt = (9x²+2) dx/dt
if x = 2 and dx/dt=5 then
dy/dt = (9*2²+2)*5 = 38*5 = 190
Answer:
f(x) = (x+5)(x-1)(x-3)
Step-by-step explanation:
From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3
From here, we have
x = -5
x = 1
x = 3
So we have the factors as;
x + 5, x - 1 , x - 3
So what this mean is that we have the function as;
f(x) = (x+5)(x-1)(x-3)
Answer:
If they are at 0 feet below. First off 0 isn't positve or negative. So it would be the hiker in death valley hiked 0 degrees below. Positive or negative 0 is neither. tell me if i'm wrong.
