Answer:

It is just because f(9x-4) is a subtraction so it goes to the right.

Then the f(x+3) is addition so it goes to left.

Step-by-step explanation:

It is like the opposite of their signs the adding is left, and the subtraction is right.

Answer:

The problem uses the perimeter formula.  P = 2w + 2l   where w is the width, and l is the length.

We know the length (l) is 3 inches longer than it's width (or l = w+3).  Substitute w +3 into Perimeter equation.

P = 2w + 2(w+3).  That simplifies to P = 4w + 6.

Since P + 42,   we have 42 = 4w +6.  With some simple algebra we find that w = 9 and l = 12.

Answer: No. The pool frame she choose will not fit into the 216 foot cubed hole. She should have picked a frame of 6ft.

Step-by-step explanation:

From the question, we are informed that Mrs. Dillard is installing a cubed swimming pool in her backyard and that the hole that her husband dug in her backyard is 216 feet cubed.

We are further told that she went to the pool store to pick out a pool frame. She chose a pool frame that had a length, width, and height of 7ft.

Since the height is 7ft, the volume will be: = 7ft × 7ft × 7ft = 343 feet cubed.

This shows that the pool frame she choose will not fit in the hole dug. She should have picked a frame of 6feet since (6ft × 6ft × 6ft) = 216 ft cubed.

Answer:

The circle's area is 153.93804 feet^2

Step-by-step explanation:

The formula for the area of a circle is [tex]a = \pi r^{2}[/tex]

Using this formula, input the number 7 in for "r" and solve:

a = pi ( 7 )^2

a = pi ( 49 )

a = 153.93804 feet^2

The area of the circle is 153.93804 feet^2. Round the number to the specified decimal point.

Answer: 182 / 182.9

Step-by-step explanation:

199.47 +57.98 + 15.40 - 89.95    

3 x 66.49 = 199.47

2 x 28.99 = 57.98

since there was only one for the belt and the coat there is no problems for that.

add and subtract all of that and you get 182 or 182.9

Step-by-step explanation:

Answer:

θ=arctan(4) or 75.96°

Step-by-step explanation:

sinθ=4cosθ (given)

sinθ/cosθ = 4cosθ/cosθ (divide both sides by cosθ)

sinθ/cosθ = 4 (cancel cosθ)

tanθ=4 (sin/cos is equal to tan)

θ=arctan(4)(transposing tan will give you arctan)

θ=75.96 (calculation will give you this)

Answer:

1) AB=BC

2) m∠ABC=105∘

3) AB=8

4) BC=8

5) BC=2⋅AB

Step-by-step explanation:

A rectangle has length 6 and height 4.

Which of these would tell you that quadrilateral ABCD is definitely not similar to this rectangle? Select all that apply.

1) AB=BC

2) m∠ABC=105∘

3) AB=8

4) BC=8

5) BC=2⋅AB

6) 2⋅AB=3⋅BC

Answer:

A rectangle is a quadrilateral (has four sides). Opposite sides of a rectangle are equal to each other and the diagonals bisect each other. Also, each of the angles in rectangle measure 90°.

1) AB = BC

Opposite sides of a rectangle are equal, hence AB is opposite to CD and BC is opposite to AD. Therefore:

AB = CD, BC = AD

AB ≠ BC

2) m∠ABC = 105°

Each of the angles in a rectangle measure 90°, therefore m∠ABC = 90°. m∠ABC ≠ 105°

3) AB = 8

AB might be the length or height of the rectangle, hence:

AB = 6 or AB = 4. AB ≠ 8

4) BC = 8

BC might be the length or height of the rectangle, hence:

BC = 6 or BC = 4. BC ≠ 8

5) BC = 2AB

If BC is the height = 4, BC ≠ 2AB

6) 2AB = 3BC

If AB is the length of the rectangle and BC is the height of the rectangle then:

2(6) = 3(4)

12 = 12

2AB = 3BC

Answer:

On top of old Smo-key all cov-ered with snow

Answer:

I would personally go with the last option, On Top of Old Smo - key all cov -ered with snow

Step-by-step explanation:

I believe this is correct because In English, there are unstressed, and stressed syllables which are generally indicated in several ways. In traditional english poetry, this generally has to do with the concept of rhythm in a metric line which is a measurement of small groups of sylables called feet established by the words in the line. This is all formed by an iambic meter which is a metrical pattern in the line of a verse or a set of sentences. This method is known as Scansion.

Answer:

3z + 1

Step-by-step explanation:

Area = 16z^2 - 10z^2 + 2z = 6z^2 + 2z = 2z(3z + 1)

Width = 2z

Area of a rectangle is given as:

Area = length × width

hence length = Area/Width

= 2z(3z + 1)/2z

= 3z + 1

Answer:26

Step-by-step explanation:

The value of f(3) is 26.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given function:

f(x) = 5(x + 1) + 2x

as, we have to find the Sean running in week 3

So, f(3) = 5(3 + 1) +2 (3)

f(3) = 5(4) + 6

f(3) = 20 +6

f(3) =26

Hence, the value of f(3) is 26.

Answer:

YXZ and NMO

Step-by-step explanation:

The HL (hypotenuse leg) theorem says that if the hypotenuse and one leg of one right triangle is congruent to the hypotenuse and one leg of another right triangle, the 2 triangles are congruent.

Therefore, we can see that the only 2 triangles that can be guaranteed to be congruent are triangles YXZ and NMO.

Correct question:

Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.

Answer:

Adrian should wake up by 6.14 am

Step-by-step explanation:

Given;

time to walk to school, = 15 mins

time to eat breakfast = 5/12 hour = 25 mins

time to get dressed = 0.7hour = 42 mins

time to shower = 0.15 hour = 9 mins

time Adrian needs to be in school = 7.45 am

Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;

7.45 am - 15 mins = 7.30 am

7.30 am - 25 mins = 7.05 am

7.05 am - 42 mins = 6.23 am

6.23 am - 9 mins = 6.14 am

Therefore, Adrian should wake up by 6.14 am

Answer:

47%

Step-by-step explanation:

.375 × .125 = .046875

rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.

move the decimal three digits to the left and you get, 47%.

Percentage markup is the percent of the difference of the selling price to the buying price of a product. The percent markup for a cup of coffee is 200%.

The percentage markup has to be find out for the cup of coffee.

Percentage markup is the percent of the difference of the selling price to the buying price of a product. It can be given as,

[tex]M=\dfrac{\rm SP-C}{C} \times 100[/tex]

Here, [tex]SP[/tex] is the selling price and [tex]C[/tex] is the cost of the product.

Given information-

The Cup o Coffee buys its coffee for $1.25 a cup.

The Cup o Coffee sells its coffee for $1.25 a cup.

To find out the percentage markup for the cup of coffee, put the values in the above formula. Thus,

[tex]M=\dfrac{3.75-1.25}{1.25} \times 100\\M=\dfrac{2.5}{1.25} \times 100\\M=200[/tex]

Hence the percent markup for a cup of coffee is 200%.

Answer:

Infinite solutions

Step-by-step explanation:

After you distribute, you get -108. The equation doesn't have an equal sign, but I don't think that matters. For every possible value of y, you get the answer -108, so the answer is either infinite solutions, or no solutions, depending on what you are trying to get the equation to equal to.

If it's a typo, and the negative is supposed to be an equal sign, the answer is no solutions.

Answer:

its D

Step-by-step explanation:

The ordered pairs that satisfy the function y = 2/3x + 1are (-3,-1) and (3,3)

The function is given as:

y = 2/3x + 1

Next, we test the options

(a) (-3,-1)

This gives

-1 = 2/3 * -3 + 1

Evaluate

-1 = -1 --- this is true

(b) (-2,-1)

This is false because -1 = -1 is true in (a)

(c) (3,3)

This gives

3 = 2/3 * 3 + 1

Evaluate

3 = 3 --- this is true

(d) (5,6)

This gives

6 = 2/3 * 5 + 1

Evaluate

6 = 4.3 --- this is false

Hence, the ordered pairs are (-3,-1) and (3,3)
