Answer:

Step by Step:
x-2y=4
+2y +2y
x=-2y+4

x-2y=4
-4 -4
x-2y-4=0
+2y +2y
x-4=2y
Divid by 2
1/2x-2= y

x=-2y+4
x=-2(1/2x-2)+4
x=-x+4+4
x=-x+8
+x +x
2x= 8
x=4

y=1/2x-2
y=1/2(4)-2
y=2-2
y=0
(4,0)

-6 = x/8 + 4 1.8 16 -80 -16

kumpel [21]

Answer:

x = - 80

Step-by-step explanation:

Given

- 6 = $\frac{x}{8}$ + 4 ( subtract 4 from both sides )

- 10 = $\frac{x}{8}$ ( multiply both sides by 8 )

- 80 = x

Elena-2011 [213]

(24 m)*(4 m) = (5 m)*height . . . . . area is the same no matter which base you use
height = (4/5)*(24 m) = 19.2 m

Find the first term and common ratio for the geometric sequence a2 =2.5,a4=62.5

fenix001 [56]

Answer:

a1 = 0.5; common ratio = 5

Step-by-step explanation:

Let the common ratio = r

a2 = 2.5

a3 = 2.5r

a4 = 2.5r * r = 2.5r^2

We are told a4 = 62.5, so

2.5r^2 = 62.5

Divide both sides by 2.5

r^2 = 25

r = 5

a2 = a1 * r

a1 = a2/r = 2.5/5 = 0.5

Answer: a1 = 0.5; common ratio = 5

Parabola,,Could you help me please??

stepan [7]

Answer:

$\large \boxed{\sf \bf \sqrt{\dfrac{10}{3}}}$

Dimension of the rectangle is

$2\times\sqrt{\dfrac{10}{3}}\\ \\10-\dfrac{10}{3}=\dfrac{20}{3}$

Step-by-step explanation:

Hello,

$\text{The area is }2x(1-x^2) \\ \\\text{The derivative is }2(10-x^2)+2x(-2x)=2(10-3x^2)\\\\\text{The derivative is }0\text{ for} 10-3x^2=0 \\\text{so for } x=\sqrt{\dfrac{10}{3}}$

Thanks
