Answer:

$30

Step-by-step explanation:

She paid $24.72 for the 2 packages of chicken because $12.36×2=$24.72.

She paid $0.99 for the broccoli because $1.98×1/2=$0.99.

She paid $3.49 for the milk because one gallon of milk costs $3.49.

$24.72+$0.99+$3.49=$29.20.

$29.20+$0.80=$30.00.

She used $30.00 to pay for the items.

Determine the equation of the line with slope −4 that passes through the point M(−2, 1).

scoray [572]

Y=mx+b
m=slope
b=y-intercept
y=-4x+b
Plug in the coordinate in place of x and y (-2,1)
1=-4(-2)+b
1=8+b
Subtract both sides by 8 to isolate B

b=-7

Final answer:
<span>y = −4x − 7

The graph of the function f(x) = -(x+6)(x + 2) is shown

Leokris [45]

Answer:

The function is increasing for all real values of x where

x < –4.

Step-by-step explanation:

we have

$f(x)=-(x+6)(x+2)$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex (h,k) represent a maximum

The roots of the function (or x-intercepts) are x=-6 and x=-2

The x-coordinate of the vertex is the midpoint of the roots

$h=(-2-6)/2=-4$

The y-coordinate of the vertex is

substitute the x-coordinate of the vertex in the quadratic equation

$k=-(-4+6)(-4+2)$

$k=-(2)(-2)$

$k=4$

The vertex is the point (-4,4)

The function is increasing in the interval (-∞,-4)

The function is decreasing in the interval (-4,∞)

Find the distance between the complex numbers. z1=9-9i, z2=10-9i

kherson [118]

$\bf z_1=\stackrel{a}{9}\stackrel{b}{-9}i\implies (9~,~-9)\qquad \qquad \qquad z_2=\stackrel{a}{10}\stackrel{b}{-9}i\implies (10~,~-9)\\\\
-------------------------------\\\\
~~~~~~~~~~~~\textit{distance between 2 points}\\ \quad \\$

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 9}} &,&{{ -9}}~) 
% (c,d)
&&(~{{ 10}} &,&{{ -9}}~)
\end{array}\quad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
d=\sqrt{[10-9]^2+[-9-(-9)]^2}\implies d=\sqrt{(10-9)^2+(-9+9)^2}
\\\\\\
d=\sqrt{1^2+0}\implies d=\sqrt{1}\implies d=1$
