In order to write this quadratic equation in standard form, first note that standard form is ax^2+bx+c for quadratics, where c is the numerical value (constant), B is the coefficient of x, and a is the coefficient of x^2 and is the leading coefficient. Next, multiply the binomials of (x-7) and (x-1). You can do this by using FOIL, or by distributing each of the terms in a binomial to each of the other terms in the other binomial. (Please let me know if you need a walk through in this step in particular). Furthermore, you should then write y= (the simplified trinomial). Now, the quadratic is in standard form. To reiterate, just simplify the two binomials by multiplying them together and writing that they're equal to y.
Answer:
x>4
Step-by-step explanation:
Step 1: Subtract 9 from both sides.
x+9−9>13−9
x>4
Answer:
X=-3
Step-by-step explanation:
3x-5x+4=10
-2x=6
x=-3
note: I wasn’t sure if the equation ended in 10 or 10x. I think it ends at 10 so that is how I solved.
Answer:
$1547.62
Step-by-step explanation:
The principal Marshall invested is $4500.
The rate of interest is 6%
The compound interest formula is
We substitute P=4500,r=0.06 and t=5 to obtain:
We simplify to get:
This gives us:
The interest after 5 years is
If a line <span>parallel </span>to one side of a <span>triangle </span>intersects the other two sides of the triangle, then the line divides these two sides proportionally.
