Answer:
Y = 1/2x+2
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
We know the slope
y = 1/2x +b
Substitute the point into the equation
0 = 1/2 (-4) +b
0 = -2+b
b=2
Y = 1/2x+2
A) <span>5x^2-13x-6
1. First, you must find the roots of the quadratic equation, by applying the quadratic formula, which is:
x=-b</span>√(b²-4ac)/2a
<span>
2. The roots are:
x1=3
x2=-2/5
3. Then, you have:
5(x-3)(x+2/5)
4. When you simplify, you obtain:
(x-3)(5x+2)
B) </span>4x^4-28x^3+48x^2<span>
1. First, you must factor the common term, which is 4x</span>^2. Then:
<span>
4x</span>^2(x^2-7x+12)
<span>
2. Now, you must apply the quadratic formula to obtain the roots of the quadratic equation: </span>x^2-7x+12. Then, you have:
x1=4
x2=3
3. Finally, you obtain:
4x^2(x-4)(x-3)
Answer:
46.25%
Step-by-step explanation:
First, add both numbers together. (86 + 74).
Next, we have 160. And that is 100%.
Now, we have to find what 74 is compared to 160.
74 is 46.25% of 160.
There's our answer.
