Answer: 7 (10) + 8 x ≥206

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

So, she worked 7 hours at a dinner for $10 per hour (7 x 10 = 70)

She also makes $8 per hour when she babysits (8 x, where x is the number of hours she babysits)

The sum of both earnings must at least 206 (more or equal) if she wants to buy the prom dress.

Mathematically speaking

7 (10) + 8 x ≥206

Simplifying

70 +8x ≥206

Perform the indicated operation. PLEASEE HELPP HURRYY!! (3 + i) + (5 + 7i) = A) -2 + 6i B) 2 + i C) 8 + 6i D) 8 + 8i
Dovator [93]

Answer:

\boxed{ \bold{  \huge{ \boxed{ \sf{8 + 8i}}}}}

Option D is the correct option.

Step-by-step explanation:

\sf{(3 + i) + (5 + 7i)}

When there is a ( + ) in front of an expression in parentheses , there is no need to change the sign.

That means, the expression remains the same.

Just remove the unnecessary parentheses

⇒\sf{3 + i + 5 + 7i}

Collect like terms and simplify

⇒\sf{3 + 5 + i + 7i}

⇒\sf{8 + 8i}

Hope I helped!

Best regards!!

a farmer is buying fencing to surround a square field of area 3600m^2. What length of fencing does he need to buy?
kirill115 [55]

Answer:

240 m

Step-by-step explanation:

The area of a square field is 3600 m².

We need to find the length of fencing he needs to buy. It means we need to find the perimeter of the field.

The area of a square field is given by :

A = side²

So,

s=\sqrt{3600} \ m\\\\s=60\ m

Length of fencing = perimeter

= 4(s)

= 4(60)

= 240 m

So, he would need to buy 240 m of fencing.

I need help with this question: Label: Coefficients, variables, terms, and constant. −2x2 + 9x − 3
iVinArrow [24]

Answer:

  coefficients: {-2, +9, -3}

  variables: {x}

  terms: {-2x^2, 9x, -3}

  constant: {-3}

Step-by-step explanation:

It is difficult to "label" here, so we'll list each, separated by commas.

<u>Coefficients</u>

Coefficients are the multiplicative factor of an expression. Depending on the expression of interest, it may consist of numbers, variables, or expressions. Here, we consider the expression of interest to be powers of x, so the coefficients are as listed. The last one (-3) is sometimes called a "constant coefficient." It multiplies x^0.

  coefficients: {-2, +9, -3}

<u>Variables</u>

A variable is usually a letter, symbol, or sequence of letters and symbols, that stands for something else--usually an unknown quantity. Its meaning and value will depend on the context. Generic variables are usually taken from the end of the alphabet: x, y, z. Their capitalization, font, or face may give special meaning. For example bold-face capital letters may be used to represent vectors or matrices.

  variables: {x}

<u>Terms</u>

A term is a product of coefficients and variables. Terms in a polynomial are separated by addition or subtraction symbols.

  terms: {-2x^2, 9x, -3}

<u>Constant</u>

"Constant" usually refers to a term containing no variables. It generally refers to a value that doesn't change.

  constant: {-3}
