Lucy has a homework assignment and she must solve the equation
-7x + 2 = 51.

Answer:

x = 29°

Step-by-step explanation:

If line l is parallel to line m, therefore:

(180° - 130°) + 101° + x° = 180° (angles on a straight line)

50° + 101° + x° = 180°

151° + x° = 180°

x = 180° - 151° (substraction property of equality)

x = 29°

Given:

The two functions are

[tex]f(x)=3x+1[/tex]

[tex]g(x)=x^2-6[/tex]

To find:

The function (f+g)(x).

Solution:

We know that,

[tex](f+g)(x)=f(x)+g(x)[/tex]

Putting the values of given functions, we  get

[tex](f+g)(x)=3x+1+x^2-6[/tex]

[tex](f+g)(x)=x^2+3x+(1-6)[/tex]

[tex](f+g)(x)=x^2+3x-5[/tex]

Therefore, the required function is [tex](f+g)(x)=x^2+3x-5[/tex].

Answer:6 inches

Answer:

-8

Step-by-step explanation:

for this, all you need to do is plug 8 into x for the equation y=8-2x

y=8-2(8)

y=8-16

y=-8

The value of y when x = 8 is,

⇒ y = - 8

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The table shows ordered pairs of the function as,

⇒ y = 8 - 2x

Now, At x = 8

The value of y is,

⇒ y = 8 - 2x

⇒ y = 8 - 2 × 8

⇒ y = 8 - 16

⇒ y = - 8

Thus, The value of y when x = 8 is,

⇒ y = - 8

Answer:

y = mx + b, so

y = -0.53x + 1.5

Step-by-step explanation:

1. Find the slope of the line. In his case, then the slope is [tex]\frac{-6}{9}[/tex], which converts to 0.53

2. Start part of the equation. y = -0.53 x

3. Find the y-intercept of the line. In this case, it is 1.5

4. Now, you can finish your equation. y = -0.53x + 1.5

Answer: 782.05 miles.

Step-by-step explanation: Percentage is a ratio expressed as fraction of 100, in other words, 61% is represented as [tex]\frac{61}{100}[/tex] or 0.61.

London slept 61% of the journey, so it means he was awake for 39% of the journey. Now the total trip is [tex]\frac{100}{100}[/tex] or 1, so the relationship will be

0.39 ---- 305 miles

   1   ----- x

[tex]x=\frac{305}{0.39}[/tex]

x = 782.05

The total length of the trip was 782.05 miles.

Answer:

  52.0833%

Step-by-step explanation:

The conditional probability formula applies.

  P(2|1) = P(2&1)/P(1)

  P(2|1) = 0.25/0.48 ≈ 0.520833

About 52.0833% of those who passed the first test also passed the second.

Comment on wording

As a fraction rounded to 4 decimal places, the value would be 0.5208 or 52.08%. This seems to ask for the percentage to be rounded to 4 decimal places, so it is 52.0833%.

Step-by-step explanation:

Answer:

NO, they are not similar.

Step-by-step explanation:

Width of rectangle J = 6 ft

Length of rectangle J = 9 ft

Width of rectangle K = 9 ft

Length of rectangle K = 12 ft

Find the ratio of their corresponding dimensions:

Ratio of their width = 6/9 = 2/3

Ratio of the length = 9/12 = 3/4

Their ratio of their corresponding dimensions are not equal. That is, their corresponding dimensions are not proportional to each other. Therefore, they are not similar.

Option A is correct, a parent function  best describes the quadratic function.

The quadratic function with a vertex at the origin and opening upward is best described as a parent function.

A parent function is the most basic form of a particular type of function.

In the case of quadratic functions, the parent function is f(x) = x².

It has a vertex at the origin (0, 0) and opens upward.

Therefore, a parent function  best describes the quadratic function.

Amanda will record 32 names for the five previous generations.

Given is that Amanda is researching her ancestry. She records names and birth dates for her parents, their parents and so on, in an online research tool.

We can write the series as -

               Amanda

     {M}                        {F}

{M}       {F}             {M}       {F}

.

.

so on

We can write the sequence as -

2, 4, 8, ....

It is a geometric sequence. For n = 5, we can write -

a(5) = arⁿ⁻¹

a(5) = 2 x (2)⁴

a(5) = 2⁵

a(5) = 2 x 2 x 2 x 2 x 2

a(5) = 32

Therefore, she will record 32 names for the five previous generations.
