y = -4.2x + 7.9 in standard form​

Answers

Answer 1

The equation of the line y = -4.2x + 7.9 expressed in standard form is 42x + 10y = 79.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is written as axe + by = c, where a and b are the coefficients of the variables x and y, respectively, and c is a constant. On the other hand, we can write the equation in point-slope form, (y - y1) = m, if we know the slope m and a point on the line (x, y).

Given the equation of a line, multiply both sides by 10 to turn the decimals into integers.

y = -4.2x + 7.9

10y = 10(-4.2x + 7.9)

10y = -42x + 79

Rewriting it in standard form ax + by = c,

10y = -42x + 79

42x + 10y = 79

In an arithmetic sequence, if you are given a3=93 and a5=135, find a=100. Must show work to receive full credit.

Answers

The 100th term of the sequence is 2130.

How to calculate the value?

a3 = a + 2d = 93

a5 = a + 4d = 135

Compute both equations

(4d - 2d) = (135 - 93)

2d = 42

d = 42/2 = 21

a + 2d = 93

a + 2(21) = 93

a + 42 = 93

a = 94 - 42 = 51

100th term will be:

= a + 99d

= 51 + 99(21)

= 51 + 2079

= 2130

proof that the span of two noncollinear vectors is the plane containing the origin and the heads of the vectors.

Answers

The Span of two noncollinear vectors is the plane containing the origin and the heads of the vectors.

Linear Span of vectors can be represented as

let [tex]x_{1} and x_{2}[/tex] be two non collinear vectors its span be written as [tex]x=a_{1} x_{1} +a_{2} x_{2}[/tex]   where [tex]a_{1}, a_{2}[/tex] are arbitrary scalars.

Subspace of vectors : a subset A of a vector space V is called a subspace of V if A is itself a vector space under scalar multiplication and addition defined on V.

The Span of two vectors is a vector space containing two vectors. Hence the span is also a vector space . It is sufficient to notice that any two independent vectors from subspace can be the basis.

Zero vector is the linear combination of these basis vector.

hence it is not possible to have a span of two non collinear vectors that does not contain origin .

Therefore, The span of two noncollinear vectors is the plane containing the origin and the heads of the vectors.

what is the monthly difference in median income for a male versus a female when both have a bachelor's degree

Answers

Answer: $1,372

Step-by-step explanation:

If using the Labor Statistics Document

A men’s median weekly earning with Bachelor’s degree only is $1,384 * 4 weeks = $5,536

A women’s medium weekly earning with a Bachelor’s degree only is $1,041 * 4 weeks = $4,164

Subtract $5,536 - $4,164 = $1,372

The full sentences are:

The typical monthly salary for women with bachelor's degrees is $3,020.

The typical annual salary for a guy with an associate's degree is $36,432.

What is Mean?

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Every month has four weeks.

The median monthly income is thus:

Earnings = 4 * $755

Earnings = $3020

As a result, the typical monthly salary for women with bachelor's degrees is $3,020.

The median annual income:

A man with an associate's degree makes $759 each week.

A month has four weeks, while a year has twelve months.

Hence, the annual median income is:

Earnings = 4 x 12 x $759

Earnings = $36,432

Thus, the typical annual salary for a guy with an associate's degree is $36,432.

Using the conditions above, the digits which can be first digit of code = 4 through 8 =4,5,6,7,8

the digits which can be second digit of code= 4,5,6,7

the digits which can be third digit of code = 0,1,3,4,5,6,8,9

number of possibilities for first digit= 5

number of possibilities for second digit=4

number of possibilities for third digit= 8

Therefore, total number of possibilities of code   = number of possibilities of first digit x number of possibilities of second digit x number of possibilities of third digit = 5 x 4 x 8=160

The contrapositive of (c) is if the patient did not take the medicine, then she will not have side effects.

What do you mean by Inverse, Contrapositive, and Converse?

Converse: By swapping the hypothesis and the conclusion, a statement can be made to mean the converse. "If two lines don't intersect, then they are parallel" is the inverse of "If two lines overlap, then they are parallel."

Inverse: Each of the original statements is presupposed to be false in an inverted statement. "If it is not snowing" would be the polar opposite of "If it is snowing." "Then it is not chilly" would be the polar opposite of "then it is cold."

Contrapositive: a statement or theorem created by swapping out the hypothesis and conclusion, or the subject and predicate, of a given statement or theorem. The opposite of "if A then B" is "if not-B then not-A."

The scatter plot showing Troy's data is given at the end of the answer.

What is a scatter plot, and why it is used in this problem?

A scatter plot shows a series of points (x,y), relating the input x to the output y.

For this problem, it is used because we want to graph a discrete function, as:

The input x is the professional year of the baseball player. The output y is the number of home runs hit by the player in the year.

Both professional year and home runs are countable amounts, that cannot assume decimal values, hence we have a discrete function and use a scatter plot.

From the table presented in this problem, the points for the scatter plot are given as follows:

(1,6), (2,9), (3,13), (4,7), (5,9).

Given the following, what is the length, l?

Answers

The value of l is. We use simple substitution of values to find the value of l is 48.

We have been given the equation V=lwh where l is the length, we can say that the given equation is that of volume of a cuboid where l is the length, w is the width and h is the height of the cuboid. We know the values of V,w and h. We have to substitute the values of V,w and h in the equation V=lwh inorder to find the value of l. Substitution method is generally used for solving system of equations where we first solve the value of one variable and then substitute the value in the other equation to find the value of the other variable. Since we only have one equation and we know the value of 3 of the 4 variables we only have to solve for one.

V=lwh

l=V/wh =[tex]\frac{576}{6.12} =\frac{576}{72}[/tex]= 48

Thus we get the value of l to be 48 by substituting the values of V,w and h.

The Spartan basketball team purchased equipment and uniforms for a total cost of $1,860. The equipment that was purchased cost $300, and the uniforms were $120 each. How many uniforms did the school purchase?

Answers

The number of uniforms the Spartan Basketball team purchased was 13.

How is the number of uniforms determined?

The number of uniforms bought by the Spartan Basketball team can be determined using the mathematical operations of subtraction and division.

In the first place, the cost of equipment is subtracted from the total cost.  The remainder is divided by the unit cost of uniforms.  The quotient is the number of uniforms bought.

Data and Calculations:

Total cost incurred = $1,860

Cost of equipment = $300

Remainder cost = $1,560 ($1,860 - $300)

Unit cost per uniform = $120

The number of uniforms bought = 13 ($1,560/$120)

Thus, the number of uniforms the Spartan basketball team purchased was 13.

n²+13n+40,

This is why;

Observe only the right side. The number is (n+8)(n+5).

Let's elaborate on that using FOIL.

F = When we multiply the first two terms, n and n, we obtain n².

O = outer instructs us to multiply n by 5 to get n*5 or 5n from the outer terms.

I = inner instructs us to multiply the inner expressions 8 by 8 and n by n to obtain 8n.

Since 8 and 5 are multiplied by L, we obtain 8*5 = 40.

Add up the outcomes: n²+5n+8n+40 = n²+13n+40

Observe how the phrase is a little bit simplified by the combination of the like terms (5n and 8n).

Here,

Given that, A package with a labeled weight of 9.4 pounds can have an actual weight plus or minus 0.22 pounds.
Let the weight labeled be y and the actual weight be x
Weight = y ± x
Maximum weight = y + x
Minimum weight = y - x

Weight = 9.4 ± 0.22
Now,
Maximum weight = 9.4 + 0.22 = 9.62 pounds
Minimum weight = 9.4 - 0.22 = 9.18 pounds
