Answer:

x = -4y + 5/2

Step-by-step explanation:

step 1: 2x +8y + -8y = 5 + -8y

2x = -8y+ 5

step 2: divide both sides by 2

2x /2 = -8y+5/2

x= -4 + 5/2

A cylinder has a height of 13 centimeters and a radius of 4 centimeters. What is its volume? Use ≈ 3.14 and round your answer

Roman55 [17]

Answer:

Volume of a cylinder = 653.12 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

Height, h = 13 cm

Radius, r = 4 cm

π = 3.14

Volume of a cylinder = πr²h

= 3.14 × (4cm)² × 13 cm

= 3.14 × 16 cm² × 13 cm

= 653.12 cm³

Volume of a cylinder = 653.12 cm³

A rectangular picture frame has side lengths of 12 in by 9.5 in what is the length of the diagonal of the picture

OleMash [197]

Answer:

Length of diagonal of picture = 15.30 inches

Step-by-step explanation:

Given that:

Side lengths of picture frame = 12 inches by 9.5 inches

As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.

Using Pythagorean theorem;

a²+b²=c²

Putting the values in the theorem

$(12)^2 + (9.5)^2 = c^2 \\144+90.25=c^2\\c^2 = 234.25$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{234.25}\\c=15.30$

Hence,

Length of diagonal of picture = 15.30 inches

The inequality x - y > 0 is satisfied by point (-1, 1).<br><br> T/F

Mekhanik [1.2K]

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

Step-by-step explanation:

We need to identify the point (-1,1) satisfies the inequality x - y > 0

Solving:

The value of x = -1 and y =1

Putting values in the inequality:

$x-y>0\\-1-1>0\\-2>0\,\,false$

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.
