5z+2z^3+3z^4 in standard form

Answer:

Step-by-step explanation:

We can solve this in either of two ways.  I'll do both.

Mathematically

3x + 2y = 8

5x + 2y = 12

Rewrite either equation to isolate y.  I'll use

3x + 2y = 8

2y = 8 - 3x

y = (8-3x)/2

Now use this value of y in the other equation:

5x + 2y = 12

5x + 2((8-3x)/2) = 12

5x + (8 - 3x) = 12

2x = 4

x = 2

Use x=2 to find y:

y = (8-3x)/2

y = (8-3*(2))/2

y = (8-6)/2

y = 1

The point is (2,1)

Graphically

Graph the two equations and find the point they intersect.  See attachment.  

We obtain the same answer:  (2,1)

Answer:

Step-by-step explanation:

To the nearest tenth, the bag of flour weighs approximately 5.5 pounds.

To convert kilograms to pounds,  use the conversion factor: 1 kilogram ≈ 2.20462 pounds.

Given that the bag of flour weighs 2.5 kilograms,  calculate its weight in pounds as follows:

Weight in pounds = Weight in kilograms × Conversion factor

Weight in pounds = 2.5 kg × 2.20462 (approximately)

Weight in pounds ≈ 5.51155 pounds

Answer:

x = 1

y = -1

Step-by-step explanation:

A*B= (4y-8 3x-3)

1-) (4×2)+(3×y)= 3y+8

2-) (4×x)+(3×(-1))= 4x-3

AB=C

(3y+8 4x-3)=(5 1)

So

3y+8=5 ; y= -3/3 = -1

4x-3=1 ; x=4/4 =1

[tex]\boxed{\sf{a<21}}[/tex]

Step-by-step explanation:

You only need to isolate the term a to solve this problem.

Add by 3 from both sides.

[tex]\sf{\dfrac{a}{7}-3+3<0+3}[/tex]

Solve.

0+3=3

a/7<3

Multiply by 7 from both sides.

[tex]\sf{\dfrac{7a}{7}<3*7}[/tex]

Solve.

3*7=21

a<21

As a result, the solution is a<21, which is our answer.

Answer:

Child's ticket is $14.   [14, without the symbol]

Senior ticket is $8.     [8, without the symbol]

(WHAT???)

Step-by-step explanation:

Let S and C stand for the numbers of Senior and Child tickets sold.

We can write equations for both days:

Day 1:   3S + 1C = 38  [sold 3 senior citizen tickets and 1 child ticket for a total of $38]

Day 2:  3S + 2C = 52  [$52 on the second day by selling 3 senior citizen tickets and 2 child tickets]

Since both equations has a "3S" term, we can easily subtract one from the other:

3S + 1C = 38

-3S - 2C = -52

        - C = -14

C = 14  The price of a children's ticket is $14.

Use C = 14 in either equation to find S:

3S + 1C = 38

3S + 14 = 38

3S          = 24

S = 8  The price of a senior ticket is $8.

Answer:

$40

Step-by-step explanation:

You can see on the graph that when Jaime works 5 hours, he will get $40.

Answer:

$40

Step-by-step explanation:

Pay rate = $8 per hour (see on graph)

($8)(5) = $40

Since the graph starts at 0,0 and the slope is constant, you can simply look at the graph and see the point (5, 40) which means that he made $40 in 5 hours.

Answer:

x=9

Step-by-step explanation:

-5(2x-3)=-3(4x-11)

Multiply to open the brackets,

-10x+15=-12x+33

Keep constants and variables on same sides,

-10x+12x=33-15
2x=18

Divide by 2 on both sides,

2x/x=18/2
x=9

Answer:

x = 9

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−5(2x−3)=−3(4x−11)

(−5)(2x) + (−5)(−3) = (−3)(4x) + (−3)(−11) (Distribute)

−10x + 15 = −12x + 33

Step 2: Add 12x to both sides.

−10x + 15 + 12x = −12x + 33 + 12x

2x+15=33

Step 3: Subtract 15 from both sides.

2x + 15 − 15 = 33 − 15

2x = 18

Step 4: Divide both sides by 2.

2x/2 = 18/2

x=9

Explanation:

The points b and e are relative max points. They are the highest point for their given neighborhood/region. In other words, they are the peak of the mountain for that little area.

In this case, point b is also the absolute maximum because it is the highest point of every point on the entire curve.

Step-by-step explanation:

A) The ratio of boys to girls in the class is; 3:4

B) The ratio of girls to boys in the class is; 4:3

We are given that;

Number of boys in class = 15

Number of girls in class = 20

Thus;

A) Ratio of boys to girls = 15:20

The highest common multiple between both numbers is 5 and so we divide both by 5 to reduce to; 3:4

B) Ratio of girls to boys = 20:15

The highest common multiple between both numbers is 5 and so we divide both by 5 to reduce to; 4:3

Answer:

8/11

Step-by-step explanation:

Let the numerator = x

Denominator =x + 3

Number : [tex]\dfrac{x}{x+3}[/tex]

[tex]\dfrac{x+14}{x+3-3}=\dfrac{11}{4}\\\\\\\dfrac{x+14}{x}=\dfrac{11}{4}[/tex]

Cross multiply,

4*(x +14) = 11*x

4x + 4*14 = 11x

4x + 56 = 11x

Subtract 4x from both sides

56 = 11x - 4x

56 = 7x

7x = 56

Divide both sides by 7

x = 56/7

x = 8
