Answer:

9 = probably D(maybe A)

I'm not sure what the answer is for #9 but I think it is most likely D. A is multiply 6 by 4 which would be substituting the value of w, for w. D is adding 2 to 40 which is combining like terms.

10 = C, 65

40+p

40+25

65

Answer:

638 miles / 11 hours = 58mph

So if he is traveling at 58 miles per hour for 7 hours, multiply the two numbers. 7(58) = 406

At the same rate of speed, Eric would travel 406 miles in 7 hours.

Step-by-step explanation:

I hope you undertand it

Answer:

522

Step-by-step explanation:

638 miles.......11hours

x miles ............ 9 hours

x = 638 * 9 / 11 = 522 miles

Answer:

a) There are 25 pencils of other colour in the bag.

b) P(Blue) = 3/7

Step-by-step explanation:

A bag contains 70 pencils out of which 15 are green and 30 are blue.

a) How many pencils of other colour are in the bag?

This is calculated as:

70 - (15 + 30)

= 70 - 45

= 25 pencils

Hence, there are 25 pencils of other colour in the bag.

b) A pencil is selected from a bag at random .What is the probability that it is blue?

P(Blue) = Number of Blue pencils/Total number of Pencils

P(Blue) = 30/70

P(Blue) = 3/7

Answer:

annual rate: r = 0.068

Step-by-step explanation:

The formula is r(t) = P(1+r)^t

Since the time is already in years we just have to solve for the rate

1 + r = 1.068

r = 0.068

The rate of change in the value of account is 0.068

'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'

According to the given problem,

Annual rate:

r = 0.068

The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]

Therefore, solving for the rate

⇒ 1 + r = 1.068

⇒ r = 0.068

Answer:

y - 6x = 18

Step-by-step explanation:

Answer:

y = 1/2x + 5

Step-by-step explanation:

We can use point slope form since we are given a point and the slope

y -y1 = m( x-x1)

where ( x1,y1) is a point and m is the slope

y -0 = 1/2 (x- -10)

y = 1/2( x+10)

y = 1/2x + 5

Answer:

This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

Answer:

-3 is your answer i am very sure

Step-by-step explanation:

Answer:

X: 1  5  2

Y: 4  8  5

Step-by-step explanation:

Given

[tex]Rule: y = x + 3[/tex]

X: ?  ?  ?

Y: 4  8  5

Required

Fill in the ?'s

We have that:

[tex]y = x + 3[/tex]

When y = 4; the rule becomes

[tex]4 = x + 3[/tex]

Subtract 3 from both sides

[tex]1 =x[/tex]

[tex]x =1[/tex]

When y = 8; the rule becomes

[tex]8 = x + 3[/tex]

Subtract 3 from both sides

[tex]5= x[/tex]

[tex]x =5[/tex]

When y = 5; the rule becomes

[tex]5 = x + 3[/tex]

Subtract 3 from both sides

[tex]2 = x[/tex]

[tex]x = 2[/tex]

So, the complete table is:

X: 1  5  2

Y: 4  8  5

Answer:

  cos(20°)

Step-by-step explanation:

The angle difference formula for cosine is ...

  cos(α -β) = cos(α)cos(β) +sin(α)sin(β)

If we let α = 50° and β = 30° then this matches the given expression:

  cos(50° -30°) = cos(50°)cos(30°) +sin(50°)sin(30°) = cos(20°)

Answer:

-13/2

Step-by-step explanation:

Answer:

P = -6.5

Step-by-step explanation:

Multiply -2 x p and -2 x -1

The equation now is -2p + 2 = 15

Subtract the 2 to both sides to cancel it out

The equation now is -2p = 13

Divided both sides by -2 to isolate the p variable

p = -6.5

You can check your answer by subtracting -6.5 by -1 (which equals -7.5)

And then multiply -7.5 by -2 which equals 15

Step-by-step explanation:

The sequence is as follows :

-59 ,-67 ,-65 ,-53 ,-31 ,...

The first term = -59

The second term = -67

Common difference = second term - first term

[tex]=-67-(-59)\\\\=-8[/tex]

To calculate the second term add (-8).

To calculate each additional term, increase the amount added by -8.

Um i think 2yyyy =f 3x-6

The required graph is attached below, which represents the given function f(x)= 3x - 6y - 2.

The below graph of the function f(x) = 3x - 6y - 2 represents a straight line in a two-dimensional coordinate system.

The equation is in standard form, where x and y are variables and the equation is equal to a constant value (-2 in this case).

To graph this equation, we can rearrange it to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

By isolating y in the equation, we get y = (3/6)x - 2/6, which simplifies to y = (1/2)x - 1/3.

The slope of the line is 1/2, meaning for every increase of 1 in the x-coordinate, the y-coordinate increases by 1/2.

The y-intercept is -1/3, which is where the line crosses the y-axis.

The complete question is as follows:

Sketch the graph of the function f(x)= 3x - 6y - 2

Answer:

Her error was that she equated 2x to 6 instead of equating 2x to 3x-5

Step-by-step explanation:

Find the diagram of the question attached.

According to the triangle given, you can see that the base angles are equal. This shows that the triangle is an isosceles triangle. If the base angles are the same, this means that the length of the slant sides are also equal i.e

2x = 3x-5

Get x first;

2x = 3x-5

2x - 3x = -5

-x = -5

x = 5

Get the side length

For side length 2x, the length is 2(5) = 10

For side length 3x-5, the length is 3(5) - 5 = 10.

Hence the length of the sides is 10

Amaya is wrong because she equated the wrong sides. She equated 2x to 6 instead of equating 2x to 3x-5 as shown in the calculation above.
