Answer:

y = 7x + 25

Step-by-step explanation:

$y - 11 = 7(x - ( - 2)) \\ y - 11 = 7(x + 2) \\ y - 11 = 7x + 14 \\ y = 7x + 14 + 11 \\ y = 7x + 25$

Triangle A: 6 cm, 8 cm, and 10 cm Triangle B: 310 in, 25in, and 35in Triangle C: 8 ft, 15 ft, and 17 ft Triangle D: 0.32 mm, 0.9

Answer:

Triangle B

Step-by-step explanation:

For a triangle with sides a, b and c,

If c² = a² + b²

Then triangle will be a right triangle.

If c² > a² + b²

Triangle will be an obtuse triangle

If c² < a² + b²

Triangle will be an acute triangle.

By applying these properties in the given triangles,

Triangle A:

6 cm, 8 cm and 10 cm

6² + 8² = 36 + 64

6² + 8² = 100 [c² = a² + b²]

Therefore, it's a right triangle.

Triangle B:

310 in, 25 in and 35 in

25² + 35² = 625 + 1225

= 1850

Since, 310² = 96100

And 96100 > 1850 [c² > a² + b²]

Therefore, It's an obtuse triangle.

Triangle C:

8 ft, 15 ft and 35 ft

8² + 15² = 64 + 225

= 289

Since, 17² = 289 [c² = a² + b²]

Therefore, It's a right triangle.

Triangle D:

0.32 mm, 0.96 mm and 1 mm

(0.32)² + (0.96)² = 1.024

Since, 1² = 1

And 1 < 1.024 [c² < a² + b²]

Therefore, triangle will be an acute triangle.

Are θ = πn and θ= π+ πn equivalent?

Marina CMI [18]

Of course, they are not equivalent.

One has an extra π in the equation.

A snail travels at a rate of 2.36 feet per minute. a. Write a rule to describe the function. b. How far will the snail travel in

34kurt

By definition we have to:
d = v * t
Where,
d: distance
v: speed
t: time
Substituting values:
d (t) = 2.36t
For t = 6 we have:
d (6) = 2.36 * (6)
d (6) = 14.16 feet
Answer:
a rule to describe the function is:
d (t) = 2.36t
the snail will travel 14.16 feet in 6 minutes
C. d (t) = 2.36t; 14.16 ft

13.) Springfield Elementary is putting on a school play

Oduvanchick [21]

45 adult tickets and 80 children tickets were sold

Solution:

Let "a" be the number of adult tickets sold

Let "c" be the number of children tickets sold

Cost of 1 adult ticket = $ 6

Cost of 1 children ticket = $ 3.50

They sold a total of 125 tickets

Therefore,

a + c = 125

c = 125 - a --------- eqn 1

They made a total of $550. Therefore, frame a equation as:

number of adult tickets sold x Cost of 1 adult ticket + number of children tickets sold x Cost of 1 children ticket = 550

$a \times 6 + c \times 3.50 = 550\\$

6a + 3.50c = 550 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

6a + 3.50(125 - a) = 550

6a + 437.5 - 3.50a = 550

2.5a = 112.5

Substitute a = 45 in eqn 1

c = 125 - 45

Thus 45 adult tickets and 80 children tickets were sold
