What is the equation of the line that passes through (-3, -1) and has a slope of 3/5 ? Put your answer in slope-intercept form. A y = 3/5x + 4/5
B y = 3/5x - 4/5
C y = -3/5x - 4/5

Answers

Answer 1
Answer:

y +1 = 3/5(x+3)

y + 1 = 3/5x + 9/5

y =3/5x + 9/5 - 1

y = 3/5x + 9/5 - 5/5

y = 3/5x + 4/5

answer:A y = 3/5x + 4/5

Which ordered pair will solve the equation 2 × 4 + x = y?A.
(5, 16)

B.
(4, 12)

C.
(3, 12)

D.
(2, 9)

Answers

This answer uses NMF, which you can find out about on my profile:

Preliminary work:
Following the BIDMAS order of operations, we can calculate part of it already, and that's the 2•4, which equals 8.
Therefore, the equation now reads:
8+x = y

x = 5:
8+5 = 13
13 ≠ 16
13 ≠ y

x = 4:
8+4 = 12
12 = 12
12 = y

Therefore, the pair is (4, 12)

Because of flu epidemic, 36 students are absent. If this is 1/6 of the school's population, what is its total population?A) 6
B) 42
C) 186
D) 216

Answers

The total population is 216. so option D is correct.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Here, 36 is only 1/6 of the population,

then, 36 x 6 = 216

6/6 or one whole of the population which is 216.

Hence, option D is correct.

The scale factor of the blueprint of a garage door to the actual garage door is 0.05. the are of the actual garage door is 220 ft^2. What is the area of the garage door on the blueprint?

A. 0.55ft^2
B. 5.5ft^2
C. 11ft^2
D. 55ft^2

Answers

Answer:

option A

0.55\ ft^(2)

Step-by-step explanation:

Let

x-------> the area of the garage door on the blueprint

y------> the area of the actual garage door

z------> scale factor

we know that

The scale factor squared is equal to the area of the garage door on the blueprint divided by the area of the actual garage door

so

z^(2)=(x)/(y)

In this problem we have

z=0.05, y=220\ ft^(2)

substitute the values and solve for x

0.05^(2)=(x)/(220)

x=220(0.05^(2))

x=0.55\ ft^(2)
The scale factor 0.05 refers to length, so for area the scale factor is 0.05²=0.0025.

We then multiply: 220 ft²*0.0025=0.55 ft² (choice A)

What is the sum of the angle measures in a 22-gon?360°
2,200°
3,600°
3,960°

Answers

Answer:

Option 3rd is correct

the sum of the interior angles measures in a 22-gon is, 3600°

Step-by-step explanation:

Sum of the interior angles of a polygon of n -sides is given by:

\tetx{Sum} = (n-2) * 180^(\circ)        ....[1]

As per the statement:

Given that:

n = 22-gon

Substitute in [1] we have;

\text{Sum} = (22-2) * 180^(\circ)

⇒\text{Sum} = 20 * 180^(\circ)

⇒\text{Sum} =3600^(\circ)

Therefore, the sum of the interior angles measures in a 22-gon is, 3600°

The sum of the angle measures in a 22-gon is 3600° (option c).

The sum of the angle measures in an n-gon (polygon with n sides) can be calculated using the formula:

Sum of interior angles = (n - 2) * 180°

For a 22-gon, n = 22, so the sum of the interior angles is:

Sum = (22 - 2) * 180°

Sum = 20 * 180°

Sum = 3600°

Therefore, the correct answer is option C: 3,600°.

What value for c will make the expression a perfect square trinomial? x2 – 7x + c

Answers

Answer: 12.25

Step-by-step explanation:

 A perfect square trinomial is written as ax^2+2abx+b^2 , where

first termax = square of first term of binomial

second term=2abx=twice the product of both terms of binomial.

and third term 'c'=square of last term of binomial

In the given polynomial ,x^2+7x+c, a=1

and 2ab = 7

When we put value of a =1, we get

2(1)b=7\n\Rightarrow\ b=(7)/(2)

Hence, in place of the question mark makes the given polynomial a perfect square trinomial =b^2=((7)/(2)^2=12.25
I assume the first part of that equation is x^2. -7/2= 3.5 ; 3.5^2=12.25 sooo it should end up as x^2-7x + 12.25. but I might be wrong.
