Answer:

1) -3/4

2) (6, 0), (0, -4)

3) connect (0,-2) and (8,0) together

Step-by-step explanation:

1) (-2) - (-5) / (-1) - 3 = -3/4

2) x = 0 -3y=12 y = -4, y= 0 2x = 12 x = 6, x intercept = (6, 0) y intercept = (0, -4)

3) x - 4y = 8 this could be written as y = x/4 - 2 and y intercept is (0, -2) and x intercept is (8, 0) so connect these points together and make a line

DerKrebs [107]

Let x be the number of children and t, the number of adults.

x + y =153
5.2x + 8.4y = 1013.2

Solving those equation will give:

x = 85 tickets sold to the kids ( and 68 tickets for adults)

Anthony's age, x, is 5 less than twice Brian's age, y. Brian's age is 7 less than Anthony's age. Which system of equations repre

ch4aika [34]

Answer:

Anthony's age: 2y - 5 = x

Brian's age: x - 7 = y

Step-by-step explanation:

Anthony: If his age is 5 less, this means - 5 is in the equation. It is 5 less than twice Brian's age, meaning × 2, or in algebra, 2y. So Anthony's age is 2y - 5

Brian: His age is 7 less so this means - 7 is in the equation. We know Anthony's age is x so Brian's age is x - 7

Another wooden plank is leaning against an outside wall of a building. The bottom of the plank is 9 ft from the wall. The length

Vladimir [108]

Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.

Let us use the Pythagorean theorem.

a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft

The height of the wall is 40 ft.

Please help me find the perimeter.

slavikrds [6]

Answer:

31.42 cm (rounded up to two decimal places)

Step-by-step explanation:

We first find the circumference of the semi-circle segment:

The circumference will be given by; $\frac{1}{2}$ × π × D (where D is the diameter)

The diameter is 6 cm so circumference is;

$\frac{1}{2}$ × π × 6 cm = 9.42 cm (rounded up to two decimal places)

The perimeter of the figure therefore is;

8cm + 6 cm + 8 cm + 9.42 cm = 31.42 cm
