Consider the functions f(x) = x − 7 and g(x) = 4x3.

What is f(x) + g(x)?

The quantity of salt in grams needed to complete the experiment is 180 grams.

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

Quantity of salt needed = (grams of baking soda x ratio of salt) / ratio of baking soda

(3 x 420) / 7 = 180 grams

The total annual FICA tax for an annual salary of $38,480 is D $2,943.72.

FICA tax comprises Social security tax + Medicare tax.

Where: Social security tax=6.2%, Medicare tax=1.45%, FICA tax =7.65%

The total annual fica tax for an annual salary of $38,480 is given by;

FICA tax=($38,480×6.2%)+($38,480×1.45%)

FICA tax=$2,385.76+$557.96

FICA tax= $2,943.72

Hence, the total annual FICA tax for an annual salary of $38,480 is D $2,943.72.

The value of the discriminant is 25, there are 2 x-intercepts does this function have and the 2 number of zeros for this function has.

The standard form of the quadratic equation is,

[tex]ax^2+bx+c=0[/tex]

Here,(a,b, c) is the real numbers and (x) is the variable.

For this equation, the discriminant value can be given as,

[tex]D=b^2-4ac[/tex]

The given quadratic function is,

[tex]f(x) = 3x^2 +7x+ 2[/tex]

Compare it with standard form, we get,

Step-by-step explanation:

Answer:

1. x - 12 = 14 {brother's age minus 12 equals sister's age}

x = 26 {added 12 to each side}

Your brother is 26.

2. x+8.95=21.35  

now you must subtract 8.95 by both sides which equals x =12.4

3. 29 compact cars.

The total number of vehicle is 37. So you can just subtract 37 by 8 which gives 29.

4. x +73=95

subtract both sides by 73. which equals 22

5. $160      He originally spent $123.45 and was left with $36.55 you just add both numbers and that's what you get altogether.

6. X-225=548

Solve for x

Add 225 to both sides. So x - 753

Answer:

Step-by-step explanation:

The mountain in "The Negro Artist and the Racial Mountain" is considered as an obstacle for Negro artists who wish for others to recognize their work. This isn't just part of their job, but it's part of a racial dispute because of their color. Langston Hughes, the author, describes these Negro artists as very talented people. These are also people who believe they can make it big as artists, but they wish to be white to do so. Black artists think they can't be accepted as people, let alone artists. So the mountain in the essay represents a huge obstacle these people have to achieve. That obstacle is being accepted by everyone else, and that includes them looking past their color before appreciating their art.

CA ≈ 10 cm

Step-by-step explanation:

Since we know 2 sides and 1 angle we can use the Law of Cosine to find the third side.

CA = √(AB²+CB²- 2· AB· CB· cos 50°)

CA = √(7² +13² -2·7·13· cos 50°)

CA = √(49 +169 -116.987345)

CA = √101.012655

CA = 10.0505

CA ≈ 10 cm

The correct answer will be option c the standard deduction is $1,613 more than chris’s deductions.

Tax is a compulsory contribution to state revenue, levied by the government on workers' income and business profits, or added to the cost of some goods, services, and transactions.

Chris's deductions for tax return = claim from property taxes +claim from medical expenses+claim form state income tax

= $1813+$1513+$76

= $4087

Standard deductions = $5700

Difference between standard deduction and Chris's deductions

= 5700-408

= $1613

Hence standard deductions is better than Chris's deductions by $1613

Answer: (C)

Step-by-step explanation:

Chris's deductions for tax return = claim from property taxes +claim from medical expenses+claim form state income tax

             = $1813+$1513+$761

             = $4087

Standard deductions = $5700

Difference between standard deduction and Chris's deductions = 5700-408

                                                                 = $1613

Hence standard deductions is better than Chris's deductions by $1613

Therefore, option (C) is correct.

weekly raise= $145

an integer describing how the raise will affect her paycheck.

Let the 1st paycheck be x (integer).

Mrs. Rodger got a weekly raise of $ 145.

So after completing the 1st week she will get $ (x+145).

Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.

= $ (x + 145 + 145)

= $ (x + 290)

therefore, in this way end of every week her salary will increase by $ 145.
