Y < 4x - 2......u have a slope of 4.....u have a y int (where the line crosses the y axis) at (0,-2)......and u have a < sign....meaning it is a dashed line shaded below the line

and if u want to find ur x int (where the line crosses the x axis) sub in 0 for y and solve for x...disregarding the inequality sign
y = 4x - 2
0 = 4x - 2
-4x = -2
x = -2/-4
x = 1/2.....so ur line crosses the x axis at (1/2,0)

so ur graph is : graph 3
========================
y > -x + 3.....u have a slope of -1....u have a y int at (0,3)....ur inequality sign is >....meaning it is a dashed line, because there is no equal sign...and it is shaded above the line since it is greater then

ur x int is :
y = -x + 3
0 = -x + 3
x = 3......x int at (3,0)

ok..I am having a problem with this one because none of ur graphs match this inequality...because ur line will cross the x axis at 3...and none of ur graphs show this
===================
y < -2......when u have y = a number (or <,>) this will be a horizontal line....it will go thru -2 all the way across....and since it has a < sign, it will be a dashed line with shading under the line.
so ur graph is : graph 2

Factor this polynomial completely x2 + 3x – 18 A. (x-2)(x + 9) B. (x+3)(x-6) оо C. (x - 3)(x+6) D. (x - 3)(x-6)

Umnica [9.8K]

Answer:

C. $(x-3)(x+6)$

Step-by-step explanation:

I think the equation meant $x^2+3x-18$ ?

Anyways, to factor these kinds of quadratic, keep into consideration:

$ax^2+bx+c=(x+w)(x+v)$

ONLY if:

$w+v=b\\wv=c$

Start off by finding factors of c, which in this case, -18:

±(1, 2, 3, 6, 9, 18)

If one of the numbers is negative then the other number must be positive.

Find which two factors will sum up to b, which in this case, is 3.

$1+(-18)\neq 3\\2+(-9)\neq 3\\3+(-6)\neq 3\\6+(-3)=3\\9+(-2)\neq 3\\18+(-1)\neq 3\\$

The only two factors that work are 6 and -3.

Replace them into the factored form:

$(x+w)(x+v)\\(x+6)(x-3)\\(x-3)(x+6)$

The endurance of both track athletes and gymnasts is recorded in terms of maximum volume of oxygen and is measured in milliliter

Olin [163]

The mean of the track athletes is given by
$\frac{89.2+45.3+89.1+57.3+61.5+80.1+47.2}{7}=67.1$

The mean of the gymnasts is given by
$\frac{72.1+78.5+66.2+47.3+63.1+89.3+65.3}{7}=68.8$

The difference in mean is given by
$68.8-67.1=1.73$ (rounded to one decimal place)
