Answer:
The x intercept is (-5,0)
Step-by-step explanation:
1. First, it would be helpful to rewrite the equation to be in y=mx+b form.
5y=4x+20
y=(4/5)x+4
2. Then, plug in 0 for y.
0=(4/5)x+4
3. Then, solve.
-4=(4/5)x
-20=4x
x=-5
Answer:
The first one
Step-by-step explanation:
Answer:5/48,3/16,0.5,0.75
Step-by-step explanation:
Given:
12 inches in 1 foot
number of inches in 2.5 feet
2.5 feet * 12 inches/1foot = 2.5 * 12 inches = 30 inches
1 foot + 1 foot + 0.5 foot = 2.5 feet
12 inches + 12 inches + 6 inches = 30 inches
12 inches : 1 foot = x : 2.5 feet
12 inches * 2.5 feet = x*1foot
30 inches * feet = x * foot
30 inches = x
<span>f '(x) = 2(3x2<span> + 5) + 6x(2x - 1)</span></span><span>= 6x2<span> + 10 + 12x</span>2<span> - 6x</span></span><span>= 18x2<span> - 6x + 10</span></span>
