Jenna says that the point (30,61) is on the line y = 2x-1 Is Jenna correct? Explain how u know?​

Answers

Answer 1

Answer:

incorrect, is you plug in the x, y=2x-1, y=60-1, or y=59,

Answer 2

Answer:

Jenna is not correct.

Step-by-step explanation:

If we subsitute the y in the equation with 61 and subsitute x with 30, it would be: 61 = 30*2-1. However 30*2-1=59 therefore it is incorrect.

For an employee training, the employee to instructor ratio is 24 to 2. If there are 39 instructors for the training, how many employees participated in the training?

Answers

Answer:

468

Step-by-step explanation:

Employee : instructor = 24 : 2

If there are 39 instructors

Employee = x

Employee : instructor = x : 39

Equate both ratios

24 : 2 = x : 39

24/2 = x/39

Cross product

24 * 39 = 2 * x

936 = 2x

x = 936/2

x = 468

Employees = x = 468

a football field is drawn to a scale of 1cm represents 5cm if the field is 70m by 50m find the length and breadth on the drawing​

Answers

Answer:

length of the drawing will be 14cm and breadth will be 10cm.

Step-by-step explanation:

if actual 5m represents 1cm in drawing then,

5m = 1cm

1m = 1/5cm

70m = (1/5)×70cm =14cm

likewise,

50m = (1/5)×50cm =10cm

thus, length in drawing is 14cm and breadth in drawing is 10cm.

Answer:

Width is 5 and length  is 14

Step-by-step explanation:

Ok this is simple all we do is divide the length 70 by 5 and the width 50 by 5 to get

14 and 10

L=14

W=5

Answer:

x = 4

Step-by-step explanation:

Given

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]

Multiply through by (x + 3)(x + 4) to clear the fractions

3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side

3x + 9 - x - 4 = x + 9

2x + 5 = x + 9 ( subtract x from both sides )

x + 5 = 9 ( subtract 5 from both sides )

x = 4

Answers

Answer:

[tex] m\angle PRQ =49\degree [/tex]

Step-by-step explanation:

[tex] m\angle PSQ = 360\degree - (128\degree + 134\degree )[/tex]

[tex] m\angle PSQ = 360\degree - 262\degree [/tex]

[tex] m\angle PSQ = 98\degree [/tex]

Now, by inscribed angle theorem:

[tex] m\angle PRQ = \frac{1}{2} \times m\angle PSQ [/tex]

[tex] m\angle PRQ = \frac{1}{2} \times 98\degree [/tex]

[tex] m\angle PRQ =49\degree [/tex]


Let f() = 3x - 1 and g(x) = 2x + 3 and find f(g(3))

Select the correct

response

f(g(3)) = 21

f(g(3)) = 19

f(g(3)) = 26

f(g(3)) = 17

Answers

Answer:

f(g(3)) = 26

Step-by-step explanation:

f(g(3))

g(3) = 2x + 3

= 2(3) + 3

= 6 + 3

= 9

f(9) = 3x - 1

= 3(9) - 1

= 27 - 1

= 26

plug in 3 for g(x) which is 9 then plug in 9 for f(x) which is 26

Answer: Figure A to Figure B is a scale factor of 0.5

Step-by-step explanation:

It's not too hard to figure out scale factor, since the two shapes are the same aside from their scale. Notice how Figure A is 4 units tall, and that Figure Bis 2 units tall. From one figure to another, use the equation Figure B/Figure A to find the scale factor. Although you won't really need to memorize all this, you can count the amount of units on your fingers and figure it out from there.

Answers

Answer:

36

Step-by-step explanation:

The formula of LCM is LCM(a,b) = ( a × b) / GCF (a,b)

The Greatest Common Factor of (9,12) = 3

Therefore

LCM of 9 and 12 = (9 × 12) / 3

= 108/3 = 36

LCM of 9 and 12 = 36

Irrespective of the method, the solution to our question LCM of 9 and 12 is the same.

Therefore, LCM of 9 and 12 is 36

What is the slope? What is the y-intercept? What is the equation of line (write is slope intercept form)?

Answers

Answer:

[tex]2x+1[/tex]

Step-by-step explanation:

Use the rise over run method.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{1}[/tex]

To find the y-intercept, look where the line crosses on the y-axis. In this case, the line crosses on 1.

Now plug in the numbers:

[tex]y=mx+b[/tex]

m = slope

b = y-intercept

[tex]y=2x+1[/tex]

[tex]2x+1[/tex]

Hence the equation of the line is, [tex]2x+1[/tex].

If a penceil has 25 grams and a apple has 75 grams more then the penceil how many grams is the apple

Answers

Answer:

The answer is 100

Step-by-step explanation:

It's 100 because it's saying that the apples is 75 more grams than the pencil. So we do 25 grams plus 75 grams which gets us 100. If your wondering where I got the 25 from it's from the amount of the pencil.

100 because when you add 25 to 75 you get 100. You add these two together because the apple is 75 grams more than the pencil so you add to find the product of the apple.
