Question 3(Multiple Choice Worth 5 points)
(02.06 MC)
What is the measure of angle x?
O40 degrees
O80 degrees
O130 degrees
O140 degrees

Answer:

Presumably you're solving for x here?  Without further information we'll assume that.

With that in mind, x is approximately equal to 0.86 and -0.46

Step-by-step explanation:

Let's start by putting it in the usual ax² + bx + c format.

[tex]5x^2- 2x = 2\\5x^2 - 2x - 2 = 0\\[/tex]

let's solve it.  First we'll multiply both sides by five, making the first term a perfect square:

[tex]25x^2 - 10x - 10 = 0\\[/tex]

Now we'll add 11 to both sides:

[tex]25x^2 - 10x + 1 = 11\\[/tex]

Which makes the left side a perfect square:

[tex](5x - 1)^2 = 11[/tex]

And now we can solve for x:

[tex](5x - 1)^2 = 11\\\\5x - 1 = \sqrt{11} \\\\5x = 1 + \sqrt{11}\\\\x = \frac{1 + \sqrt{11}}{5}[/tex]

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.

That gives us two answers:

[tex]x = \frac{1 + \sqrt{11}}{5}\\\\x \approx \frac{1 + 3.32}5\\\\x \approx \frac{4.32}5\\\\x \approx 0.86[/tex]             [tex]x = \frac{1 - \sqrt{11}}{5}\\\\x \approx \frac{1 - 3.32}5\\\\x \approx \frac{-2.32}5\\\\x \approx -0.46[/tex]

Answer:

6

Step-by-step explanation:

10 percent decimal form = 0.10

60 * 0.10 = 6

Answer:

Yes it is a proportional relationship

Step-by-step explanation:

That is because 20 and 10 are your original and 40 and 20 and 60 and 30 match with it.

Answer:

x < 15/2

Step-by-step explanation:

Step 1: Divide both sides by 2.

2x/2 < 15/2

x < 15/2

Answer:

answer of 2a)

He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then

24–16=a

His new account balance is $8.

He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then

8+b=28

His deposited $20 in his account.

He has $28 and spent $34. Let c represent his account balance after he bought the book. Then

28–34=c

His new account balance is -$6.

He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then

−6+d=0

He deposited $6.

answer of 2b)

If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Answer:

The range of the set of ordered pairs are [tex]Y =\{-1,-7,-11,-15\}[/tex].

Step-by-step explanation:

Let [tex](x,y)[/tex] be an ordered pair, where [tex]x[/tex] corresponds to an element of the domain and [tex]y[/tex], an element of the range. Hence, the range of the set of ordered pair are:

[tex]Y =\{-1,-7,-11,-15\}[/tex]

The range of the set of ordered pairs are [tex]Y =\{-1,-7,-11,-15\}[/tex].

Answer:

z1 = -17 + 0i

Step-by-step explanation:

Given the complex number z1 ​ =17[cos(π)+isin(π)], we are to express it in rectangular form as shown;

Since cos(π) = -1 and sin(π) = 0, the equation becomes;

z1 ​ =17[cos(π)+isin(π)]

z1 ​ =17[(-1)+i(0)]

z1 = 17(-1 + 0i)

z1 = -17 + 0i

Hence the complex number in rectangular form is expressed as z1 = -17 + 0i

Answer:

7. Option B:40 is the correct answer.

8. Option D: y = 40x+75 is the correct answer.

Step-by-step explanation:

Given that:

Charges per hour = $40

Fee charged by repairman = $75

x = number of hours

y = total fee

According to given statement;

y = 40x+75

The standard equation is

y = mx + b

On comparing;

Slope of the line is given by m, therefore

Slope = m = 40

Hence,

7. Option B:40 is the correct answer.

8. Option D: y = 40x+75 is the correct answer.

Answer:

Vertex form: [tex]y = 3(x - 4)^2 - 2[/tex]

Vertex: (4, -2)

Step-by-step explanation:

Hello!

We have to complete the square, and then simplify.

The equation in vertex form is [tex]y = 3(x - 4)^2 - 2[/tex]

The vertex is (4,-2)

Vertex form is f(x) = a(x - h)² + k, where (h, k) is the vertex.

Answer:

Slope = 3/4

Answer:

-5x + 4

Step-by-step explanation:

He bought 10 pounds of Golden apples and 20 pounds of Fuji apples

which costs him $20 and $60.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Let Fuji apples be F and Golden apples be G.

In total, he bought 30 pounds of apples.

∴ F + G = 30...(i)

And,

He bought 3 pounds of Fuji apples and 2 pounds of Golden apples.

3F + 2G = 80...(ii)

Now, multiplying eqn(i) by 3 and subtracting from (ii) we get G = 10 and hence F = 20.

So, he bought 10 pounds of Golden apples and 20 pounds of Fuji apples

which costs him $20 and $60.

Answer:

12x+4

Step-by-step explanation:

We can solve this by using PEMDAS (parentheses exponents multiplication division addition subtraction) to solve this in the correct order:

4+8÷2x (6-3)

So first we solve (6-3) since it’s in parentheses:

4+8÷2x (3)

Now we multiply 3 times 8/2x:

4+8/2x(3)

4+12x

(Put in order)

12x+4

And that^ is the answer because we cannot simplify any further!

Number of men= 13.99 = 14

Step-by-step explanation:

Giving the following information:

There are 49 female performers in a dance recital. The ratio of men to women is 2:7.

First, we determine the proportion of men to women:

Proportion men to women= 2/7= 0.2857

Now, we calculate the number of men in the show:

Number of men= 0.2857*49

Number of men= 13.99 = 14
