Justify whether the equation y=9x−4 defines a linear or nonlinear function.

Answer: 2y - 9.5  

Step-by-step explanation:

3(1/2y -2.5) + 2(3/12y - 1)  First distribute      

3/2y - 7.5 + 6/12y - 2   Combine like terms  

18/12y + 6/12y  - 7.5-2  

24/12y - 9.5

2y  - 9.5

Step-by-step explanation:

For every increase in the x-value by 1,

the y-value decreases by -2.

(From 3 to 1 and from 1 to -1)

Hence, slope of line k

= Rise/Run = (-2)/1 = -2. (A)

Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.

Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.

In this problem, two of the points are: (1,3) and (2,1).

Hence, applying the division:

[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]

The slope of the line is of -2, hence option A is correct.

Answer:

Riya does not pass

Step-by-step explanation:

From the question:

Section A has 80 marks

Section B has 120 marks.

The total marks from both sections = 200 marks

To pass, Riya needs to score 65% of the total marks.

Hence: 65% of 200 marks

= 65/100 × 200

= 130 marks.

To pass Riya must score 130 marks.

Riya scores:

For section A

55% in Section A

Her marks in section A = 55% × 80

= 55/100 × 80

= 44 marks

For section B

70% in Section B.

Her marks in section A = 70% × 120

= 70/100 × 120

= 84 marks

Therefore , the total marks Riya scored in both sections =

44 marks + 84 marks

= 128 marks

Riya scored a total of 128 marks. SHE DOES NOT PASS. Because the pass mark is a total of 130 marks from Section A and Section B

Step-by-step explanation:

Since, both the Pentagons are similar. So, their corresponding sides would be in proportion.

Therefore,

[tex] \frac{4}{4x} = \frac{(x + 2)}{48} \\ \\ \frac{1}{x} = \frac{(x + 2)}{48} \\ \\ x(x + 2) = 48 \\ \\ {x}^{2} + 2x = 48 \\ \\ {x}^{2} + 2x - 48 = 0 \\ \\ {x}^{2} + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8 \: \: or \: \: x = 6 \\ \\ \because \: x \: cannot \: be \: - ve \\ \implies \: x = 6[/tex]

(-Infinity,Infinity) and [0, Infinity)

Answer:

Step-by-step explanation:

It says perpendicular, which means if you graphed the line given and the one you have to make, they would intersect at a right angle. I'm going to presume the x is after -2/3 since you didn't put one in, I hope that's correct.

The first part to solving problems like these is to invert the slope, which just means you have to switch the sign on it (negative to positive/positive to negative) and switch the numerator and denominator. This makes the new slope 3/2.

The next step is to find the y-intercept, which they thankfully gave you in this problem (when x=0 the y-value is always the y intercept), but you'll usually have to find it.

The equation is y=3/2x+5. You should double check this, I'm good at math but it's been a bit.

Answer:

f(4)=52

Step-by-step explanation:

Answer:

Larry places 19 puzzles

Step-by-step explanation:

Step one:

given data

let the number of puzzles Larry places be x

and let the number of puzzles Drew places be y

so

y=3x-11

Step two:

We are told that Drew places at least 10

so for x= 10

y= 3*10-11

y=30-11

y=19

Answer:

1)The equation of the Parallel line is 2x -y -4=0

2) The equation of the perpendicular line of the given line x+2y+8=0

Step-by-step explanation:

Step(i):-

Given function f(x) = 2x+3 and passes through (0,-4)

Let y =f(x) = 2x+3

    y = 2x+3

⇒ 2x -y +3=0

The equation of the parallel line of the given line 2x - y +k =0

This line is passes through the point (0,-4)

⇒ 2 (0) -(-4)+k=0

            4 +k=0

        ⇒    k =-4

The equation of the Parallel line is 2x -y -4=0

2)

Step(ii):-

Given function f(x) = 2x+3

Let y = 2 x + 3

 2x - y +3=0

The equation of the perpendicular line   bx -ay +k=0

The equation of the perpendicular line of the given line -x-2y +k =0

This line is passes through the point (0,-4)

⇒  (0) -2(-4)+k=0

            8 +k=0

        ⇒    k =-8

The equation of the perpendicular line of the given line -x-2y -8 =0

The equation of the perpendicular line of the given line x+2y+8=0

Answer:

(A) Hank

(B) Hank

Step-by-step explanation:

Hank made 6 out of 8 foul shots Nelly made 8 out of 20 foul shots

(A) Who scored the most baskets?

Converting the shots to decimal

Hank = 6/8 = 3/4 = 0.75

Nelly = 8/20 = 1/4 = 0.40

The person who scored the most baskets is Hank

(B) Compare Hank and Nelly to determine whose son is more accurate

Determining who is more accurate,

Hank = 6/8 = 3/4

This means out of every 4 shots, Hank scored 3

Nelly = 8/20 = 1/4

This means out of every 4 shots, Nelly scored 1

Therefore, Hank is more accurate

Answer:

let c = cashew pounds, w = walnut pounds, m = mixed pounds

Here's what we know:

c + w = m

7c + 5.5w = 6.50m

m = 35

So we now have:

c + w = 35

7c + 5.5w = 227.5

We can use substitution or elimination here. Let's try substitution in this case:

c = 35 - w

7(35 - 7) + 5.5w = 227.5

245 - 7w + 5.5w = 227.5

245 - 1.5w = 227.5

-1.5w = -17.5

w = 11 2/3

Now to solve for cashews:

c = 35 - 11 2/3

c = 23 1/3

Check:

23 1/3 * 7 + 5.5 * 11 2/3 = 227.5

163 1/3 + 64 1/6 = 227.5

163 2/6 + 64 1/6 = 227.5

227 3/6 = 227.5

227.5 = 227.5
