If f(x)=49-x^2 and g(x)=7-x, which is the rule of the function (f-g)(x)?

A. -x^2-x-56
B. -x^2+x+42
C. 7+x
D. x^3-7x^2-49x=343

Answer:

The rate of change is [tex]\frac{7}{4}[/tex] or 1.75. That shows that the cost per video game is $1.75

Step-by-step explanation:

The change in y over change of x or slope can be calculated using the equation:

[tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] so take the last two points: (10, 25) and (15, 33.75).

33.75-25=8.75

15-10=5

8.75/5=1.75 (7/4)

x=video games

y=total cost

Since slope is change in y (cost) per change of x (video games), the answer is:

1.75 cost per video game

Answer:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

8.5% = 8.5/100 = 8.5 ÷ 100 = 0.085.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 8.5% of its value.

Percentage increase = 8.5% × 15,837.77

New value =

15,837.77 + Percentage increase =

15,837.77 + (8.5% × 15,837.77) =

15,837.77 + 8.5% × 15,837.77 =

(1 + 8.5%) × 15,837.77 =

(100% + 8.5%) × 15,837.77 =

108.5% × 15,837.77 =

108.5 ÷ 100 × 15,837.77 =

108.5 × 15,837.77 ÷ 100 =

1,718,398.045 ÷ 100 =

17,183.98045 ≈

17,183.98

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 15,837.77 =

17,183.98045 - 15,837.77 =

1,346.21045 ≈

1,346.21

Proof.

Calculate percentage increase:

Percentage increase =

8.5% × 15,837.77 =

8.5 ÷ 100 × 15,837.77 =

8.5 × 15,837.77 ÷ 100 =

134,621.045 ÷ 100 =

1,346.21045 ≈

1,346.21

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

(8 + 9) + 3 is equivalent to 8 + (9 + 3) using the property of associative.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(8 + 9) + 3 = 17 + 3 = 20

8 + (9 + 3) = 8 + 12 = 20

This is the property of associative.

Thus,

(8 + 9) + 3 is equivalent to 8 + (9 + 3) using the property of associative.

Answer: 2/3x + 15

Step-by-step explanation:

(⅚x + 10) - (⅙x -5)

The first thing to do here is to open the bracket. This will be:

= ⅚x + 10 - ⅙x + 5

= ⅚x - ⅙x + 10 + 5

= 4/6x + 15

= 2/3x + 15

Answer:

500 miles

Step-by-step explanation:

Step one:

A car costs $3,500 and costs $4 in gas to drive fifteen miles

let the total cost be y and let the number of miles be x

y= 3500+4x-----------1

If another car costs $4,500 but only need $2 in gas to drive fifteen miles,

let the total cost be y and let the number of miles be x

y= 4500+2x----------------2

Step two:

Equate the two expressions for the total cost

3500+4x=4500+2x

solve for x

4x-2x=4500-3500

2x= 1000

divide both sides by 2

x= 1000/2

x= 500 miles

Answer:

0

Step-by-step explanation:

First, we plug in the -3 into the equation:

18 - 2(-3)^2

0

Answer:

The answer would be the one where the graph is between -4 and 4 but not including them. Since it is < it doesn’t include -4 or 4 and since it is less than 4 and absolute value it has to be between them.

Answer:

∡3 = 142°

Step-by-step explanation:

28° + 10° + ∡3 = 180° (Sum of angles in a triangle)

38° + ∡3 = 180°

∡3 = 180° - 38°

∡3 = 142°

Alternate method:

38° + ∡3 = 180° (Sum of angles on a straight line)

∡3 = 180° - 38°

∡3 = 142°

Answer:

38 degree + 180 degree = [ sum of angle on a straight line]

3= 180 degree - 38 degree

3= 142 degree.

Answer:(03.01 LC)

coordinate plane with segments AB and A prime B prime with points L, M, N, and O at A 1 comma 2, B 1 comma negative 1, A prime 3 comma 2, B prime 3 comma negative 4, L negative 1 comma 4, M negative 1 comma 2, N negative 1 comma 0, and O negative 1 comma negative 2

segment AB was dilated by scale factor of 2 to create segment A prime B prime.

Which point is the center of dilation? (1 point)

L

M

N

O

Step-by-step explanation:

To find the center of dilation, plot a line between the corresponding points of the pre-image and the image. First, plot a line through A and A'. Then, plot a line through B and B'.

Answer is M

The slope is a number that tells how steepness it is.

Meaning that the bigger slope it is, the more steepness it is.

We compare how steepness it is. Greater slope, greater steepness.

As plotted the graph of g(x) = -7x - 1

The g(x) does have more steepness than f(x).

Therefore, the answer is A.

Answer:

7.2 miles

Step-by-step explanation:

Janet hikes a trail 3.6 miles long each day. Considering the forth and back path, she trails 2*3.6= 7.2 miles.

Since she has hiked 5 days in the past week, she has hiked 5*7.2 = 36 miles.

The question does not specify if the path back is to be considered. If not, then the total distance traveled is 3.6*5 = 18 miles.

Answer:

x = 13

Step-by-step explanation:

x and 167 are a linear pair, x plus 167 will equal 180

x + 167 = 180

x = 180 - 167

x = 13

To check: x + x + 167 + 167 = 360

x = 13

13 + 13 + 167 + 167 = 360

26 + 167 + 167 = 360

26 + 334 = 360

360 = 360

Answer:

[tex]x = 13[/tex]

Step-by-step explanation:

[tex]x + 167 = 180(linear \: pair) \\ x = 180 - 167 \\ x = 13[/tex]
