What is the solution to the inequality?<br><br><br> -2x-4 less than or equal to 11

Rashid [163]

Answer:

x ≤ $\frac{-15}{2}$

Step-by-step explanation:

So first you would start by getting rid of the -4. To get rid of -4, you would need to + 4 on each side leaving you with -2x ≤ 15. Now you need to get rid of -2 from x so that would convert equation to x ≤ $\frac{-15}{2}$ . Hoped it helped!

Y and x vary directly. If the constant of variation is 1/2, then what is the value of y when x= -6

san4es73 [151]

If x=-6, then y=-3

Further explanation:

Direct proportion means that if a quanitity increases the other quantity also increases and vice versa

The direct proportion is written as:

If y and x vary directly then

y∝x

y=kx

where k is the proportionality constant

If k=1/2 then the expression will be:

$y=\frac{1}{2}x\\Putting\ x=-6\\y=\frac{1}{2}* (-6)\\y=-3$

If x=-6, then y=-3

Note that while the figure is made up of rectangle and parallelogram, then the area of this figure

$A_{figure}=A_{rectangle}+A_{parallelogram}.$

1. The area of rectangle is

$A_{rectangle\ ABCF}=AB\cdot BC.$

The vertices of rectangle are points A(-2,-2), B(0,-6), C(8,-2) and F(6,2). Then

$AB=\sqrt{(-2-0)^2+(-2+6)^2}=\sqrt{4+16}=\sqrt{20}=2\sqrt{5},\\ \\BC=\sqrt{(8-0)^2+(-2+6)^2}=\sqrt{64+16}=\sqrt{80}=4\sqrt{5}.$

Therefore,

$A_{rectangle\ ABCF}=2\sqrt{5}\cdot 4\sqrt{5}=8\cdot 5=40\ un.^2$

2. The area of parallelogram can be calculated using formula

$A_{parallelogram\ FCDE}=\text{base}\cdot \text{height}.$

The base of parallelogram is segment CD with length

$CD=\sqrt{(8-8)^2+(3+2)^2}=\sqrt{25}=5$

and the height has length 2 un. Then

$A_{parallelogram\ FCDE}=5\cdot 2=10\ un^2.$

3. Now

$A_{figure}=40+10=50\ un.^2$
