Explain Linear Equations in One Variable.

Answers

A linear equation in one variable is the equation that has one one term

How to explain a linear equation?

You should understand that an equation is linear if there highest power of the equation is one (1)

The linear equation can have one or two terms. But in this regard, it the equation contains only a term or variable say x,y,m, p, q, a, b etc, the equation is said to be in one variable.

Taking the following sets of equations

x+4 = 5

2y-8=0

x+4=3-8x

These equations are linear and they contain only one variable.

Therefore, a linear equation is the equation containing one variable whose highest power of the variable is one.

Answers

Using similar triangles, it is found that the measure of angle B is of 74º.

What are similar triangles?

Similar triangles are triangles that have the same angle measures, and whose side lengths are proportional.

In this problem, the triangle ABC was translated, resulting in triangle A'B'C'. A translation does not change the measures of the angles, hence their angles are given as follows:

80º, 26º and B.

The sum of the internal angles of a triangle is of 180º, hence:

80 + 26 + B = 180

B = 74º.

The measure of angle B is of 74º.

Answers

26 pregnant women who were getting prenatal care and had either acknowledged marijuana usage or had urine samples test positive for marijuana underwent semi-structured interviews. During interviews, it was determined where women got their information on the dangers of prenatal marijuana use and how valuable they thought it was. Two coders independently coded the interview data, iteratively improved the codes, and looked over the transcripts for themes.

The most frequently used illegal substance during pregnancy is marijuana. Little is known about how pregnant marijuana users learn about and comprehend perinatal marijuana use. To further understand their information-seeking behaviors and opinions of the value of material accessible about perinatal marijuana use, we performed a qualitative study among pregnant marijuana users.

Qualitative data include the eye color of students involved in after-school activities and the characteristics of various types of birds.

What do we mean by Qualitative data?Qualitative data are those that cannot be expressed numerically and cannot be measured.

So,

The time it took students to finish their exams in minutes can be measured numerically, so it is quantitative data.Because the eye color of students involved in after-school activities cannot be measured, the data is qualitative.The characteristics of various types of birds cannot be measured numerically - thus, it is qualitative data.The last exam score can be measured and expressed numerically, so it is quantitative data.The weights of various books can also be measured, resulting in quantitative data.

What is the vertex of the quadratic function below?
y=x² +12%-7
O A. (-6,-43)
OB. (-6,-29)
O C. (6,3)
OD. (6,29)

Answers

Answer:

Step-by-step explanation:

assuming you meant y = x² + 12x - 7 , then

given a quadratic in standard form

y = ax² + bx + c (a ≠ 0 )

the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 12x - 7 ← is in standard form

with a = 1 , b = 12 , then x- coordinate of vertex is

x = - [tex]\frac{12}{2}[/tex] = - 6

substitute x = - 6 into the equation for corresponding y- coordinate

y = (- 6)² + 12(- 6) - 7

= 36 - 72 - 7

= - 43

vertex = (- 6, - 43 )

What is the equation of the line that passes through the point (4, 6) and has an
undefined slope?

what’s the equation

Answers

Answer:

x = 4

Step-by-step explanation:

You want the equation of the vertical line through (4, 6).

Undefined slope

Slope is the ratio of rise to run for a line. When the "run" is zero, that ratio becomes undefined. The "run" will be zero for any rise when the line is vertical.

Equation

The equation of such a line has the form ...

x = c . . . . . for some constant c

In order for this equation to be satisfied when (x, y) = (4, 6), the value of the constant must match the x-coordinate of the point.

The equation is x = 4.

HELP ASAP I DON'T UNDERSTAND

Answers

Answer:

Step-by-step explanation:

x² + 7x + 12 = 0

consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)

the factors are + 3 and + 4 , since

3 × 4 = + 12 and 3 + 4 = + 7 , then

(x + 3)(x + 4) = 0

equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x + 4 = 0 ⇒ x = - 4

Sharon packs apples into bags. if she packs 6 apples in each bag, she will have 3 apples left. if she packs 7 apples in a bag, she will be four apples short. how many bags does she have? how many apples does she have?

Answers

The total number of bags Sharon have is 7 and the total number of apples Sharon have is 45.

Let total number of bags = x

Let total number of apples Sharon has = y

If she packs 6 apples in each bag, she will have 3 apples left. So, mathematically we can write

6x + 3 = y equation 1

If she packs 7 apples in a bag, she will be four apples short. So, mathematically we can write

7x - 4 = y equation 2

On subtracting equation 1 from equation 2 , we get

x - 7 = 0

⇒ x = 7

Substitute x = 7 in equation 1 , we get

6 ( 7 ) + 3 = y

⇒ y = 45

The total number of bags Sharon have is 7 and the total number of apples Sharon have is 45.

To find: The relation when 1.50 changes to 2.75.

Finding:

AS given in the question, 40 - 1.50(x) represents the money spent by Gloria in her school cafeteria, where:40 represents the total money she has.1.50 represents the money spent on each meal by her.x represents the number of meals.If 1.50 changes to 2.75, it means that the cost of her meal increased from 1.50 to 2.75, by 1.25 dollars. Further, it means that her expenses have increased now and that her total money will now be spent earlier than what would have been spent if she spent 1.50 dollars on each meal.The new relation will be given by the linear equation: 40 - 2.75x.

Hence, The given function is an equation describing the expenses of Gloria at her school cafeteria: She has 40 dollars in total and spends 2.75 dollars for each meal; 40 - 2.75x is the new function of linear equation.

Step-by-step explanation:

3, 15, 75...

15/3=5

Every term multiplied by 5 is the next term. Hence, the equation for this sequence can be expressed as:

y=3*[tex]5^{x-1}[/tex] ==> y is the term when x is the term number and 3 is the first number in the sequence

Now let's solve for the 10th term:

Answers

The expressions of all the functions are;

1) f(x) = 0.75x

2)g(x) = 0.8x

3) (f o g)(x) = 0.6x

4) (g o f)(x) = 0.6x

How to create Algebraic Equations?

We are told that f(x) is the price with the $20 coupon applied, and

g(x) is the price with the 15% discount applied. Thus;

1) An expression for f(x) is;

f(x) = (1 - 0.25)x = 0.75x

f(x) = 0.75x

2) An expression for g(x) is;

g(x) = (1 - 0.2)x = 0.8x

g(x) = 0.8x

3) An expression for (f o g)(x) is;

(f o g)(x) = f(g(x)) = 0.75(0.8x) = 0.6x

(f o g)(x) = 0.6x

4) An expression for (g o f)(x) is;

(g o f)(x) = 0.8(0.75x) = 0.6x

(g o f)(x) = 0.6x

The Springfield zoo is breeding gorillas. They have 3 gorillas which can mate and give birth. After the first year there are 7 gorillas. After the second year there are 11 gorillas. If the gorillas continue to increase at the same rate, how long will it take for the Springfield zoo to have 35 gorillas?

Answers

Using a linear function, it will take 8 years for the Springfield zoo to have 35 gorillas.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For this problem, the parameters are given as follows:

m = 4, b = 3.

Hence the number of gorillas after x years is given by:

G(x) = 3 + 4x.

It will have 35 gorillas when:

G(x) = 35.

Hence:

3 + 4x = 35.

4x = 32.

x = 32/4

x = 8.

It will take 8 years for the Springfield zoo to have 35 gorillas.

y = A cos[B(x-C)] + D, where

A = amplitude,

period = 2π / |B|

C = Phase shift

D = vertical shift

Amplitude = (Max value - Min value) / 2

Amplitude = 80 - 40 / 2

Amplitude = 20

24 = 2π / |B|

B = π / 12

vertical shift = Max value + Min value / 2

D = 80 + 40 / 2

D = 60

Since the temp. is min. at t = 0, we will use negative cosine.

H(t) = -20 cos(π t/ 12) + 60
