1) Q.1 Find the equation of a line that passes through (1, 2) and (5, 4).

Answers

Answer 1

equation of a line is y=mx+ c

where m is that gradient and c is y intercept

so first we find the gradient (m)

M= change in y intercept ÷change in x

M=4-2÷5-1

M=2÷4=1/2(as a fraction)(you can also use o.5)

there 1/2is the gradient

then to find the equation of the line

y= 1/2x +c (from coordinates 1,2 we substitute)

2=1/2(1)+c

2-1/2=c

c=1.5

or

from the coordinates 5,4

4=1/2(5) +c

4=5/2+ c

c=4-5/2

c=1.5

equation of the line=y=0.5x + 1.5

or y=1/2x +1.5

hope it helps you^_^

Choose the statement that describes a relationship that has a negative slope. A Stan makes $2 for every customer on his newspaper route. B Lisa's parents give her $10 each week for her allowance. C Greg pays $25 each time he goes rock climbing. D The booster club makes $3 profit for each t-shirt they sell.

Answers

The statement that describes a relationship that has a negative slope: "Greg pays $25 each time he goes rock climbing".

What is negative slope?

A negative slope indicates that two variables are adversely connected; that is, when x rises, y falls, and when x falls, y rises. A negative slope on a line graph signifies that the line falls as it travels from left to right. For example, when the number of individuals that quit smoking (x) grows, the number of persons developing lung cancer (y) drops. This relationship's graph has a negative slope. Positive slopes are predicated on the fact that when x grows, so does y, hence the change in y/change in x is positive. Negative slopes are based on the fact that when x grows, y decreases, resulting in a negative change in y/positive change in x, yielding a negative response.

Here,

"Greg pays $25 every time he goes rock climbing," says the statement describing a connection with a negative slope.

The paragraph proof is a proof written in the form of a paragraph. In other words, it is a logical argument written as a paragraph, giving evidence and details to arrive at a conclusion.

What is Paragraph prove statement?

Paragraph proofs are comprehensive paragraphs that explain the process of each proof. Like two-column proofs, they have multiple steps and justifications. But instead of columns, the given information is formatted like a word problem — written out in long-hand format.

Since vertical angles are congruent, it is known that angle DCB is congruent to angle ACE. It can now be concluded that triangle DCB is congruent to triangle ACE according to the Side-Angle-Side (SAS) theorem.

There are two different types of proofs: informal and formal. Formal proof is often introduced using a two-column format, as favored by many geometry teachers.

The situation regarding the experimental probability is described as follows:

The probability that she makes a shot is of 62.5% = 5/8. Use whole numbers from 1 to 8, with 1-5 representing shots that she makes, and 6-8 representing the shots that she misses. For each trial, generate 10 random numbers. Count the number of trials in which the numbers 1 - 5 appears 3 or more times. Divide the number of trials in which she made at least 3 shots by the total number of trials.

How to obtain a probability?

A probability is calculated as the division of the number of desired outcomes by the number of total outcomes.

The theoretical probability of making a shot in this problem is given as follows:

62.5%.

The equivalent fraction is given as follows:

5/8.

Hence, to obtain the experimental probability, we need to design an experiment for which there are eight possibilites, with five of them composing a success and three of them composing a failure.

Patrick and Oscar both went bowling last weekend, but not together. Patrick went during open bowling time, paying $1 for shoe rental and $6 per hour. Oscar went on family night, when each hour was $1 and shoe rental was $11. As it turned out, they played for the same number of hours and spent the same amount. How many hours did each one bowl? How much did each one spend?

Answers

Answer:

The spent 2 hours and $13.

-------------------------------

Patrick has spent:

6x + 1 for x hours

Oscar has spent:

x + 11 for x hours

Since they both spent same amount of money, we have:

6x + 1 = x + 116x - x = 11 - 15x = 10x = 2

They both spent 2 hours and $(2 + 11) = $13.

Solve using systems by substitution whats is y=x+8 and x+y=2

Answers

Answer:

Step-by-step explanation:

y = x + 8

x + y = 2

using substitution, since y is equal to x + 8 we substitute it for the y in x + y = 2

so we get: x + (x+8) =2

then we simplify, getting 2x + 8 = 2

We make the x on its own on one side of the equation by subtracting 8 on both sides.

2x = -6

divide

x = -3

y = 5

(if x = -3, y = 5 because -3 + 8 =5)

test answer

5 = -3 + 8 works and -3 + 5 = 2 works as well

when f(x) = 6x² - 2x - 5, evaluate f(-2)

Answers

Answer:

23

Step-by-step explanation:

Given Information:

f(x) = 6x² - 2x - 5

If we have to evaluate f(-2), we can consider that f(x) = f(-2) = 6x²- 2x - 5.

So, if f(x) = f(-2), then we have the following solution: x = -2.

Now, we can substitute the solution into the quadratic equation and simplify it to its simplest possible form using the solution (x = -2).

f(-2) = 6x² - 2x - 5 f(-2) = 6(-2)² - 2(-2) - 5 f(-2) = 6(-2)(-2) - 2(-2) - 5 f(-2) = 6(4) + 2(2) - 5 f(-2) = 24 + 4 - 5 f(-2) = 24 - 1 = 23

Therefore, the evaluated form for f(-2) is 23.

Garrett went to Good Buys where all prices are discounted 15%. He buys a vintage Waring blender, after the 15% discount, for $42. What is the original price of the blender before the discount. Round your answer to the nearest hundredths.

Answers

The original price of the blender before the discount is $49.41.

How to calculate the original price of the blender

We shall represent the original price of the blender with the letter x so that we use $x to evaluate for the original price before the discount price as follows:

x - 15x/100 = $42 {simply the left hand expression to a single fraction}

(100x - 15x)/100 = $42 {simply the terms in the bracket}

$85x/100 = $42

$85x = $4200 {cross multiplication}

$85x/$85 = $4200/$85 {divide through by $85}

x = $49.41

For what value of A is x 5 a factor of x² 3x² ax 10?

Answers

The value of A when x - 5 is a factor of x³ - 3x² + ax - 10 is -8.

A polynomial factor is a polynomial that divides another polynomial exactly, with no remainder.

For example, if we have a polynomial P(x) = x³ - 3x² + ax - 10, and we have a polynomial factor F(x) = x - 5, we can say that P(x) is divisible by F(x) with no remainder.

In general, a polynomial of degree n has n roots (or zeroes) and the factorization of polynomial can be expressed as a product of its roots and its corresponding multiplicity.

To find the value of A, set x = 5 in the equation x³ - 3x² + ax - 10 and solve for A that will make the equation equal to zero..

So when x = 5, we have:

x³ - 3x² + ax - 10 = 0

(5)³ - 3(5)² + a(5) - 10 = 0

125 - 75 + 5a - 10 = 0

5a = -40

a = -8

Hence, if x - 5 is a factor of x³ - 3x² + ax - 10, then A is equal to -8.

Does scientific notation have to be greater than 1?

Answers

The mantissa of scientific notation is between 1 and 10 in absolute value, or 1 ≤ |a| < 10.  It can be 1, hence, it does not have to be greater than 1.

A scientific notation has the form:

a x 10ᵇ

Where b is an integer and is called exponent.

a is a real number between 1 and 10 (in absolute value), it includes 1 but not 10, or we can write a should satisfy 1 ≤ |a| < 10.

Usually, a is called mantissa.

Example:

2567 can be written in scientific notation as:

2567 = 2.567 x 10³

0.0045 can be written in scientific notation as:

The line that has the constant of proportionality between y and x of 1 / 2 , is C. Line C.

How to find the constant of proportionality ?

The ratio used to compare changes in one variable to those in another is known as the constant of proportionality. The dependent variable fluctuates more with the independent variable when the proportionality constant increases.

The formula for the constant of proportionality is:

= Value of y / Value of x

For Line A we have point ( 1, 7 ) so the constant of proportionality is:

= 7 / 1

= 7

For line B, we have point (2, 3 ) so the constant of proportionality is:

= 3 / 2

so i think that this angle is in quadrant IV to satisfy for the of the both requirements.

but angle 0 seems to try and mean something other than 0 degrees or 0 radians. so It probably just means theta, which is a 0 probably with a line through it

The polynomial 3x³ 2x² +3 can be written as 3x³ + 2x² + 3. In order to get the polynomial 3x² + 4, we need to add a polynomial which is equal to -3x³ + 5x² + 1.

3x³ + 2x² + 3 + (-3x³ + 5x² + 1) = 3x² + 4

3x³ + (-3x³) = 0

2x² + 5x² = 7x²
