Answer:

The sum of (−3x−4y) and (x+3y) in simplest terms will be:

[tex]\left(-3x-4y\right)+\left(x+3y\right)=-2x-y[/tex]

Step-by-step explanation:

Given

Finding the sum of (−3x−4y) and (x+3y)

[tex]\left(-3x-4y\right)+\left(x+3y\right)[/tex]

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

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

[tex]=-2x-4y+3y[/tex]

[tex]=-2x-y[/tex]

Therefore, the sum of (−3x−4y) and (x+3y) in simplest terms will be:

[tex]\left(-3x-4y\right)+\left(x+3y\right)=-2x-y[/tex]

Answer:

y=3/4x-4

Answer:

9000

Step-by-step explanation:

they make 600 every minute so in 15 minutes they would make 9000

Answer:

They can make 9000 crayons in 15 minutes.

Step-by-step explanation:

Figure out the ratio:

[tex]\frac{2400}{4}[/tex]

Simplify it to get the total number of crayons that they can make in one minute.

2400/4 = 600

They can make 600 crayons per minute.

Now, you should have a proportion.

[tex]\frac{600}{1}[/tex]

Now, multiply the denominator and numerator by 15 because whatever you do to the denominator you have to do to the numerator.

You should now have your answer.

[tex]\frac{9000}{15}[/tex]

Crayola can make 9000 crayons in 15 minutes.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

Answer:

The equation of the line is:

[tex]y=(-\frac{1}{2})x+1[/tex]

Therefore, option a is the correct answer.

Step-by-step explanation:

Given the points

Finding the slope

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:-1\right)[/tex]

[tex]m=\frac{-1-2}{4-\left(-2\right)}[/tex]

[tex]m=-\frac{1}{2}[/tex]

As the point-slope form of the equation of the line is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

substituting the values [tex]m=-\frac{1}{2}[/tex] and the point (-2, 2)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-2=\frac{-1}{2}\left(x-\left(-2\right)\right)[/tex]

[tex]y-2=\frac{-1}{2}\left(x+2\right)[/tex]

[tex]y-2=-\frac{1}{2}\left(x+2\right)[/tex]       ∵[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]

Add 2 to both sides

[tex]y-2+2=-\frac{1}{2}\left(x+2\right)+2[/tex]

[tex]y=(-\frac{1}{2})x+1[/tex]

Hence, the equation of the line is:

[tex]y=(-\frac{1}{2})x+1[/tex]

Therefore, option a is the correct answer.

Answer:

159 m

Step-by-step explanation:

From the information given:

It was stated that if the ostrich ran towards the east direction in 7.95 s, let say the distance from the starting point is O towards the east side E, let called the distance towards the east side to be OE.

Again, the ostrich then runs in the south direction for 161 m, let the distance be OS.

Also, let the magnitude of the resultant displacement between the east direction to the south direction be ES = 226m.

We are to find, the magnitude of the ostrich's eastward component.

i.e. The distance traveled from the center to the east direction within the time frame of 7.95 s.

Using the Pythagoras rule:

ES² = OE² + OS²

226² = OE² + 161²

226² -  161² = OE²

OE²  =  226² -  161²

OE²  = 51076 - 25921

OE²  =  51076 - 25921

OE²  =  25155

[tex]OE = \sqrt{25155}[/tex]

OE =  158.60 m

OE ≅ 159 m

Thus, the magnitude of the ostrich's towards the eastward component. = 159 m.

Answer:

a=0."3636"

b=repeating.(explanation down below)

Step-by-step explanation:

a)decimal

=16

44

=4

 11

=0."3636"

b) the decimal is repeating. the term terminating means having an end or to stop. the current decimal is repeating as it channels a continuous cycle 0.3636... hence concluding that it is repeating(or recurring)

Answer:

Step-by-step explanatinon:

percent is per hundred

4 dimes is  40 cents or $0.40 or 40/100 of a dollar which is40%

1 nickel and 3 pennies or 8 cents or $0.08 Or 8/100 or 8%

5 quarters and one dime is 135/100 or  $1.35 or 135/100 which is 135%

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

7 dimes and 1 nickel = 7*10 + 5 = 75 cents.

A dollar has 100 cents

75 cents * 1 dollar/100  cents  * 100 =

0.75 * 100 = 75%

Answer:

Step-by-step explanation:

Answer:

It's actually -4/5 if you are multiplying -2 times 2/5

-1/5 out of a fraction= -0.2

-4/5 out a fraction= -0.8

Step-by-step explanation:

you basically divide the numbers which turns into a decimal

Answer:

the answer is b

Step-by-step explanation:

the answer would be b because you add 12+12 then 5+5 and if you add those together it would be 34 then you would add the diagonal lines together which would be 20 so then you would add 34 plus 26 and then you would get 60 which is b

Answer:

Step-by-step explanation:

Step one:

given data

total money =$11,000

number of chairs to be purchased= 400

cost per chair=$72

Step two:

the cost of 400 chairs will be

400*72= $28,800

there will be a deficit of

=28,800-11,000

=$17,800.

This shows that the office manager does not have enough funds for the purchase.

Hence to support his thinking,

A. He does a calculation to find the cost of 400 chairs and compares the amount to the amount he has.

Answer:

i would say 105 and if not then its 115

Answer:

A, 105

Step-by-step explanation:

alternate exterior angles are equal to each other so divide 150 by half and you get 75, then do 180-75 and you end up with 105 because its a linear pair

Answer:

the answer is B

f(x)=-2x+3

Step-by-step explanation:

to get the -2x I did --->

pick two points I used (0,3) and (1,1) and used the equation [tex]\frac{y2-y1}{x2-x1}[/tex]

where y2 would be 1 and y1 would be 3

and where x2 would be 1 and x1 would be 0

so you would put the numbers in the equation which would look like[tex]\frac{1-3}{1-0}=\frac{-2}{1}[/tex] and equal -2 which would be -2x in the answer

And the +3 is the y-intercept

Answer:

x = 21 degrees!

Step-by-step explanation:

3x + x + 96 = 180

4x +96 = 180

Subtract 96 from both sides!

4x = 84

Divide by 4 from both sides!

x = 21 degrees

Answer:

x=21°

Step-by-step explanation:

3x+x+96°=180°

4x=180°-96°

4x=84°

x=84°/4

x=21°

Answer:

m = 8

Step-by-step explanation:

Step 1: Write the equation neatly. {3 (m + 4) = 36}

Step 2: Distribute 3 to m and 4. {3 x m = 3m} {3 x 4 = 12}

Step 3: Write the new equation. {3m + 12 = 36}

Step 4: Subtract 12 from both sides. {12 - 12 = 0} {36 - 12 = 24}

Step 5: Write the new equation. {3m = 24}

Step 6: Divide 3 from both sides. {3m / 3 = m} {24 / 3 = 8}

Step 7: Write the new equation and you get your answer. {m = 8}
