What is the constant of proportionality in the table shown ?

Answer:

-20x + 8y

Step-by-step explanation:

- 8x -3(4x-y)+7y

First distribute,

-3(4x)= -12x

-3(-y)= y

so then that would be -8x -12x +y+7y

Next,

Combine like terms

-20x+ 8y

Answer: y = 0.6x + 5.8

Answer:

if f(g(x)) = g(f(x)), then x is equal to zero.

Step-by-step explanation:

given:

f(x) = 2x²

g(x) = x + 1

then:

f(g(x)) = 2(x + 1)²

g(f(x) = 2x² + 1

so if:

f(g(x)) = g(f(x))

then:

2(x + 1)² = 2x² + 1

2(x² + 2x + 1) = 2x² + 1

2x² + 2x + 1 = 2x² + 1

2x = 0

x = 0

Answer:

45 miles

Step-by-step explanation:

Complete Question

What does 3 3/4 inches represent on the map?

1 inch is equivalent to 12 miles on the map

From the above question, the scale on the map is given as:

1 inch = 12 miles

Hence, 3 3/4 inches = x miles

Cross Multiply

1 inch × x miles = 3 3/4 inches × 12 miles

x miles = 3 3/4 inches × 12 miles/1 inch

x miles = 15/4 × 12 miles

x miles = 45 miles

Therefore, 3 3/4 inches represents 45 miles on the map.

Answer:

x < 5/9

Step-by-step explanation:

Answer: x < 5/9

Step-by-step explanation:

36x < 20 (divide both sides by 36)

x < 20/36 (simplify the fraction)

x < 5/9

Answer:

That would be an obtuse-scalene triangle.

Step-by-step explanation:

It is scalene because none of the sides are congruent. This means that none of the angles or sides are the same.

Answer:

See explanations below

Step-by-step explanation:

Slope intercept form of the equation is expressed as y = mx+b

m is the slope

b is the intercept

Given the coordinates (4, -11/3) and (1/2, -29/6)

Slope m = -29/6-(-11/3)÷(1/2-4)

m = (-29/6+11/3)÷(-7/2)

m = -29+22/6÷(-7/2)

m = -7/6÷(-7/2)

m = -7/6×2/-7

m = 2/6

m = 1/3

Get the intercept b

Substitute m= 1/3 and (4, -11/3) into y = MX+b

-11/3 = 1/3(4)+b

-11/3 = 4/3+b

b= -11/3-4/3

b= -15/3

b =-5

Get the required equation

y = 1/3 x -5 (slope-intercept form)

Point slope form of the equation is expressed as y-y0 = m(x-x0)

Substituting m = 1/3 and the point (4,-11/3)

x0 = 4

y0 = -11/3

y - (-11/3) = 1/3(x-4)

y+11/3 = 1/3(x-4) (point-slope form)

For standard format

Recall that y = 1/3x - 5

Multiply through by 3

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

3y = x-15

3y-x = -15(standard form)

Answer:

y = -2/3x + 6

Step-by-step explanation:

Kind of hard to explain but...

From 0,0 go up 6, that is where the + 6 comes from in the answer

The -2/3 is because if you go down 2 (aka -2) and right 3 (aka 3) from point 0,6 you land on point 4,4

Step-by-step explanation:

Multiples of a number are the numbers that a number can be divided by without any remainder.

The buses X and Y will leave at the same time by 8:40 am

To calculate when buses X and Y will leave at the time, we would have to find the Lowest Common Multiple of 20 and 25 minutes.

Find and list multiple until the first common multiple is found. This is the lowest common multiple.

Multiples of 20:

20, 40, 60, 80, 100, 120, 140

Multiples of 25:

25, 50, 75, 100, 125, 150

Therefore,

LCM(20, 25) = 100

The LCM is 100 minutes

Converting 100 minutes

60 minutes = 1 hour

100 minutes = ?

Cross Multiply

100 minutes x 1 hour / 60 minutes

= 1 2/3 hours.

This can be rewritten as :

= 1 hr 40 minutes

Adding this to 7am

7 am + 1 hr 40 minutes = 8 : 40am

Therefore, the buses X and Y will leave at the same time by 8:40 am
