This is really simple any of the values that are larger than -4 should be correct, those values would be -3, 2, 10 (A,B,E)
The answer is this:
4 x 10 = 40 - 0.4 = 3.6
$3.60
Answer:
coolshirts.com will sell the t shirts for %7.5
Explaination:
the company pays 2.50 to make the shirt and has a 300% mark up.
300% as a decimal is 3 and then you just multiply 2.50 by 3 to get 7.5
Answer: the equation is
4x^2 + 4x - 12
Step-by-step explanation:
A quadratic equation is an equation in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where
a is the leading coefficient
c is a constant
Assuming we want to write the quadratic equation in x, from the information given, the roots which are given are -2 and 1 and the leading coefficient is 4.
Therefore, the linear factors of the quadratic equation will be (x+2) and (x-1)
the equation becomes
(x+2)(x-1)
= x^2 - x +2x - 3
= x^2 + x - 3
Given a leading coefficient of 4, we will multiply the quadratic expression by 4. It becomes
4(x^2 + x - 3)
= 4x^2 + 4x - 12
