Answer:

A

Step-by-step explanation:

2.1 Factoring 4x2+12x+9 The first term is, 4x2 its coefficient is 4 . The middle term is, +12x its coefficient is 12 . The last term, "the constant", is +9 Step-1 : Multiply the coefficient of the first term by the constant 4 • 9 = 36 Step-2 : Find two factors of 36 whose sum equals the coefficient of the middle term, which is 12 .

What are the x- and y-intercepts of the line 6x−y=10?
Elena-2011 [213]

Step-by-step explanation:

This equation is in Standard Form. To find the x and y intercepts, it is easier to convert it to slope-intercept form, or y = mx + b.

6x - y = 10

-y = -6x + 10

y = 6x - 10

In slope-interecept form, you can see that the y-int, b, is -10, the constant. To find x, set y to zero.

0 = 6x - 10

10 = 6x

10/6 = x

5/3 = x

there is a 20% discount with a set of tires in normally sells for $368. How much will be tires cost after the discount?
ICE Princess25 [194]
Same as before, if we take 368 to be the 100%, how much is 20% off that?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
368&100\\
d&20
\end{array}\implies \cfrac{368}{d}=\cfrac{100}{20}\implies \cfrac{368\cdot 20}{100}=d

so, the discount is that much, thus, the discounted price is then 368 - d.
