help. Solve for x and show work

Step-by-step explanation:

y = f(x)

this has the same meaning. y is just the variable for the functional result value. while x is usually used as variable for the input value.

so (I recommend to use the brackets to make sure that people understand it is meant that x gets multilevel by 3 in the numerator, and not by 4 in the denominator),

y = 12 + (3/4)x

is the same as

f(x) = 12 + (3/4)x

you could also write it as

f(x) = 12 + 3x/4

don't skip things, always think about the rules of the sequence of the operations in an expression, and how a reader could understand it. always be as precise, complete and consistent as possible.

Answer:

  3/5 < 3/4   (The symbol you need is <.)

Step-by-step explanation:

The problem is asking you to compare the fractions 3/5 and 3/4. You need to supply a comparison symbol, one of {<, =, >}.

In general, when you are asked to compare two values, you are being asked which one is greater (or smaller). Sometimes, you are being asked for the amount by which one is greater than the other (their difference), and sometimes you are being asked for the factor by which one is greater than the other (their ratio).

You can do the arithmetic to find the appropriate difference or ratio, or you can use your number sense to identify the larger (or smaller) number.

As you know, the denominator of a fraction tells you how many pieces the pie has been divided into.

In the fraction 3/5, the 5 tells you each piece is 1/5 of the whole, that there are 5 equal pieces.

In the fraction 3/4, the 4 tells you each piece is 1/4 of the whole, that there are 4 equal pieces.

A pie divided into 5 pieces instead of 4 has smaller pieces. That is ...

  1/5 < 1/4

When there are 3 pieces of each, this relation still holds:

  3×(1/5) < 3×(1/4)   ⇒   3/5 < 3/4

__

Additional comment

Here, the numerators are the same, so we only need to compare the denominators to find the relationship. If the denominators are the same, we can compare the numerators.

If neither is the same, it is often useful to multiply one or the other or both of the fractions by some value so they will have a common numerator or denominator. The usual recommendation is to give the fractions a common denominator.

Here, the denominators can be made to be 20 in each case.

  [tex]\dfrac{3}{5}=\dfrac{3}{5}\cdot\dfrac{4}{4}=\dfrac{12}{20}\\\\\dfrac{3}{4}=\dfrac{3}{4}\cdot\dfrac{5}{5}=\dfrac{15}{20}[/tex]

The denominators are now the same, so we can compare values by comparing the numerators. 12 < 15, so 12/20 < 15/20 and 3/5 < 3/4.

The like terms are -xy, 1/2xy and 2xy

Like terms are expressions that have the same variable factor

Take for instance, 2x and 5x are like terms because their variable factors are x

Also, 5x and 2xy are not like terms

Answer:

1. 15.17ft          2. 18.57ft           3. 22.41%

Step-by-step explanation:

1. What was the length of one side of the garage originally?

Area of a square = s × s which is also equal to s²

s means one side of the square, as it is a square, all sides are equal.

so

230 = s²

s = √230 = 15.17

2. What is the length of one side of the garage now?

The original area of the garage was 230ft²

But now, the area has increased by 50%

Increased Area = 230 × 50% = 115ft²

Total Area = 230 + 115 = 345ft²

In the question, they are saying that after the area is increased, the garage is still a square which means that the side lengths have equal values.

Area = s²

345 = s²

s = √345 = 18.57

3. What was the percentage increase of the length of one side?

  Length : Percentage

    15.17   :      100

   18.57   :         x

When the length of one side was 15.17, the percentage was 100% as that is what the original length was, we can use ratio and proportion to find what the percentage will be when the length is 18.57.

Now cross multiply

18.57 × 100 = 15.17x

1857 = 15.17x

1857/15.17 = x

x = 122. 41

The new percentage is 122.41%

The difference between both percentages is:

122.41 - 100 = 22.41

And 22.41 is the percentage increase.

Answer:

cos = 4/5

Step-by-step explanation:

having sides 3 and 5, means that this is a right triangle with sides 3,4, and 5

cos = adjacent side/ hypotenuse

sin= opposite side/ hypotenuse

since 5 is the biggest number it will be the hypotenuse since that is the longest side, so it will stay on the bottom.

The equation can be summarized as; p = $50 + 3($100 ). Hence William was paid $350.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

Let p represents the paycheck.

William  paid her parents $50 for rent. After paying the rent he evenly divided the rest of the amount into three parts.

He puts $ 100 into her savings account. It means that he also puts $100 into checking account and $ 100 into retirement fund

If we put the parts together, the equation we get is;

p = $50 +$100 +$100 +$100

The equation can be summarized as;

p = $50 + 3($100 )

Now we can easily find how much was William  paid;

p = $50 + 3($100)

p = $50 +$300

p = $350

Hence William was paid $350.

Given x is Complimentary angle

Also, line1 is parallel to line2

Thus,
x [tex]+[/tex]  139° [tex]=[/tex] 132° [Alternate angle]

x [tex]=[/tex] 132°[tex]_[/tex][tex]_[/tex]- 139°

x[tex]=[/tex] -7°

What is Complimentary angle?

When two angles are added together, complementary angles are defined. When the total of the two angles is 90 degrees, we get a pair of complimentary angles. In other terms, two angles are said to be complimentary if they combine to make a right angle. In this case, we say that the two angles work well together.

If two angles sum to 90 degrees, they are said to be complimentary angles. In other terms, a right angle is created when two complimentary angles are combined (90 degrees). If the sum of angles 1 and 2 equals 90 degrees (i.e., angle 1 plus angle 2 = 90°), then the angles are complementary and are referred to as one another's complements.

60° + 30° in the illustration below equals 90°. These two angles are therefore complimentary according to the "Definition of Complementary Angles." The term "complement" refers to each angle that is one of the complimentary angles. Here,

The opposite of 30° is 60°.

Answer:

y = - 2x² + 8x + 5

Step-by-step explanation:

the equation of a quadratic function in standard form is

y = ax² + bx + c ( a ≠ 0 )

to find a, b and c use ordered pairs from the table

(0, 5 )

5 = a(0)² + b(0) + c = 0 + 0 + c = 5 ⇒ c = 5 , then

y = ax² + bx + 5

(1, 11 )

11 = a(1)² + b(1) + 5 = a + b + 5 ( subtract 5 from both sides )

a + b = 6 → (1)

(2, 13 )

13 = a(2)² + b(2) + 5 = 4a + 2b + 5 ( subtract 5 from both sides )

4a + 2b = 8 → (2)

solve the 2 equations simultaneously to find a and b

multiplying (1) by - 2 and adding to (2) will eliminate b

- 2a - 2b = - 12 → (3)

add (2) and (3) term by term to eliminate b

2a + 0 = - 4

2a = - 4 ( divide both sides by 2 )

a = - 2

substitute a = - 2 into (1) and solve for b

- 2 + b = 6 ( add 2 to both sides )

b = 8

then a = - 2, b = 8 and c = 5 gives the standard quadratic function

y = - 2x² + 8x + 5

Step-by-step explanation:

standard equation would be

y = ax² + bx + c

out of that we know already from (0, 5) that c = 5, as

a×0² + b×0 + c = 5.

because of (-1, -5) we see

-5 = a×1 + b×-1 + 5 = a - b + 5

-10 = a - b

or

a = b - 10

because of (1, 11) we see

11 = a×1 + b×1 + 5 = a + b + 5

6 = a + b

now we use the previous equation :

6 = (b - 10) + b = 2b - 10

16 = 2b

b = 8

.

a = b - 10 = 8 - 10 = -2

so, our standard equation is

y = -2x² + 8x + 5

one on right is 2,-2 and one on left is -1,1
