Answer

Given: Sorry the images are at the bottom.

To find:

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).

Part B: Which function has a greater y-intercept? Justify your answer.

Solution:

On inspection of values of x and f(x) it is clear that f(x) is a linear function

i.e.

1)Slope of f(x) and y-intercept of f(x):

Convert the function in slope intercept form and calculate the slope.

Slope intercept form:

Here,

Slope of f(x)=1,

y-intercept of f(x)=(0,0)

2) Slope and y-intercept of g(x):

Slope of g(x)=7

Y-INTERCEPT of g(x) =(0,2)

Part A:

Slope of f(x) is 1 and slope of g(x) is 7.

Part B:

g(x) has a greater y-intercept.

Hope it helps you.

Step-by-step explanation:

Answer:

With river 12 miles per hour

Against river 9 miles per hour

wv = water velocity  vsw = boat velocity in still water

vsw +wv =  12 mph

vsw -wv = 9 mph

2 * vsw = 21 mph

boat velocity in still water = 10.5

Since vsw + wv = 12 then

water velocity = 1.5 mph

Step-by-step explanation:

Answer:

Olivia is 9 years old.

Step-by-step explanation:

1/3 of o (Olivia's age) increased by 12, is twice of o minus 3. The equation for this would be 1/3o + 12 = 2o - 3. (The left side could be o/3 as well.)

1/3o + 12 = 2o - 3

Subtract 2o from both sides

-5/3o + 12 = -3

Subtract 12 from both sides

-5/3o = -3 - 12

Subtract 12 from -3 to get -15

-5/3o = -15

Multiply both sides by -3/5, the reciprocal of -5/3

o = -15 (-3/5)

Express -15(-3/5) as a single fraction

o = -15 (-3)/5

Multiply -15 by -3 to get 45

o = 45/5

Divide 45 by 5 to get 9.

o = 9

To make sure this works, substitute 9 for o.

1/3(9) + 12 = 2(9) - 3

3 + 12 = 18 - 3

15 = 15

Both sides match each other, so o equals 9.

Olivia is 9 years old

Twice her age decreased by 3 is expressed as 2x - 3

Equate both expressions and find x

1/3x + 12 = 2x - 3

1/3x - 2x = -3-12

(x-6x)/3 = -15

-5x = -45

x = 9

Hence Olivia is 9 years old

Answer:

36

Step-by-step explanation:

keep, flip, change...

24 ÷ [tex]\frac{2}{3}[/tex] would be the same as [tex]\frac{24}{1}[/tex] × [tex]\frac{3}{2}[/tex] which is equal to [tex]\frac{72}{2}[/tex] (36 if you simplify it)

The number of dose of 2/3oz of liquid medication does the bottle contain is 36.

Fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here (a) is the numerator and (b) is the denominator.

A bottle contains 24oz of liquid medication and the average dose is 2/3oz.

Let suppose the number of dose does the bottle contain is n. There is total 24oz of liquid medication in the bottol.

As the average dose is 2/3oz. Thus the number of dose in the bottle which has 24oz of liquid medication is,

[tex]n=24\div\dfrac{2}{3}\\n=24\times\dfrac{3}{2}\\n=36[/tex]

Thus, the number of dose of 2/3oz of liquid medication does the bottle contain is 36.

Answer:

8 (4+3)

Step-by-step explanation:

32 + 24 as a product of two factors using the GCF is 8(4 + 3).

The greatest common factor (GCF) of two number is the largest number which can divide both the numbers completely.

Given,

The expression is 32 + 24 .

The greatest common factor of 24 and 32 can be found using the following method.

Common factors of 24 and 32 are:

2, 4, and 8

Out of all the common factors 8 is the largest number.

Therefore  greatest common factor of 24 and 32 is equal to 8.

Taking the GCF out we get:

                                       8(3 + 4)

Hence, 32 + 24 as a product of two factors using the GCF is 8(4 + 3).

Answer:

y=x+2

Step-by-step explanation:

we know the slopes have to be equal because the lines are parallel, so the slope is 1, or written as x. plug the point given, (-6,-4), and the slope, 1, into the y=mx+b equation to find the y-intercept. then solve. then put the slope and y-intercept together for the equation of line h.

y=mx+b, m=1, x=-6, y=-4

-4=(1)(-6)+b

-4=-6+b

2=b

Answer:

only one solution

Step-by-step explanation:

Complete question:

Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x − y = 2 3x + y = −6 one and only one solution infinitely many solutions no solution Find the solution, if one exists. (If there are infinitely many solutions, express x and y in terms of the parameter t. If there is no solution, enter NO SOLUTION.) (x, y) =

Given the expression

2x − y = 2 .... 1

3x + y = −6  ..... 2

We are to determine the number of solution the equation has:

Add equation 1 and 2

2x + 3x = 2 - 6

5x = -4

x = -4/5

Substitute x = -4/5 into 1

From 1: 2x − y = 2 .... 1

2(-4/5) - y = 2

-8/5 - y = -2

-y = -2+8/5

-y = -10+8/5

-y = -2/5

y = 2/5

Since the value of x and y are just 1 hence the system of equations has ine solution
