Answer:

the slope is -5/2 and the y-intercept is (0,-3)

Step-by-step explanation:

Answer:

y = -5/2x - 3

Step-by-step explanation:

First you distribute, -5/2 or -2.5 (x +4)

Which results in y - 7 = -2.5x + -10

and then add +7 to both sides

y = -2.5x + (-3 )

Turn x into a fraction and:

y = -5/2x - 3 The last answer choice

Two expressions with equal sign is equation, if (m/n)(x) for x=-3 is (m/n)(-3)=m(-3)/n(-3).

Two expressions with equal sign is called as Equation.

Given,
(m/n)(x) for x=-3

i.e means we need to find (m/n)(-3)

So we have to calculate by putting -3 in to two functions m and n.

(m/n)(-3)=m(-3)/n(-3)

Therefore (m/n)(x) for x=-3 is (m/n)(-3)=m(-3)/n(-3).

Answer: a

Step-by-step explanation:

First term

[tex]\int \sqrt{10x-15} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int \sqrt{u} \mathrm{du}\\\\=\frac{1}{15}u^{3/2}+C\\\\=\frac{1}{15}(10x-15)^{3/2}+C[/tex]

Second term

[tex]\int (10x-15)^{10} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int u^{10} \mathrm{du}\\\\=\frac{1}{110} u^{11}+C\\ \\ =\frac{1}{110}(10x-15)^{11}+C[/tex]

Third term

[tex]\int \frac{1}{10x-15} \mathrm{dx}[/tex]

We can use the substitution u=10x-15, meaning dx = 1/10 du.

[tex]=\frac{1}{10} \int \frac{1}{u} \mathrm{du}\\\\=\frac{1}{10} \ln u+C\\\\=\frac{1}{10} \ln(10x-15)+C[/tex]

Adding these results, we get the answer to be a.

Answer:

w = 7

Step-by-step explanation:

12.75w + 25 = 114.25

12.75w + 25 - 25 = 114.25 - 25

12.75w = 89.25

12.75w/12.75 = 89.25/12.75

w = 7

If an increase in the price of blue jeans leads to an increase in the demand for tennis shoes, then blue jeans and tennis shoes are substitutes.

Two or more expressions with an Equal sign is called as Equation.

The statement "If an increase in the price of blue jeans leads to an increase in the demand for tennis shoes"

Substitutes are two goods that can be used in place of each other for a similar purpose.

In this case, if the price of blue jeans increases, consumers may switch to buying more tennis shoes instead, since they serve a similar purpose in terms of clothing.

Complements are two goods that are used together, such as peanut butter and jelly.

Normal goods are goods whose demand increases as income increases, while inferior goods are goods whose demand decreases as income increases.

Hence, If an increase in the price of blue jeans leads to an increase in the demand for tennis shoes, then blue jeans and tennis shoes are substitutes.

Answer:

0%

Step-by-step explanation:

The gain on the first oven = 18000 x 20% = 18000 x 20/100
= 18000 x 0.2 = 3600. Since it is a gain, we have to add this number

So selling price = 18000 + 3600 = 21600

The loss on the second oven is also the same 18000 x 0.2 = 3600. This time, it being a loss, selling price = 18000-3600 Total= 14400

The total before sales price of both ovens C  = 18000 + 18000 = 36,000

Total sold price S = 14, 400 + 21,600 = 36000

So net gain/loss = S - C = 36000 - 36000 = 0

So net gain/loss as percent = 0%

Step-by-step explanation:

the slope is a line is always the factor of x.

and it is the ratio (y coordinate difference / x coordinate difference) when going from one point to another.

y = 2x + 4

has the slope 2. which is 2/1. so, for every increase of x by 1 unit, y increases by 2 units.

and this line has a y-intercept of 4 (the y-value when x = 0).

remember, the slope-intercept form of a line is

y = ax + b

a is the slope, b is the y-intercept.

a perpendicular slope (90°) turns that ratio upside down and flips the sign (because if the original line was going up, the perpendicular line is going down and vice versa).

so, the slope of the perpendicular line is -1/2.

the y-intercept was already given to us, so the desired line equation is

y = -1/2 x + 3

or

y = -x/2 + 3

Table number 4 is showing the value of Y as a function of X.

A binary connection in mathematics links elements of one set, referred to as the domain, with elements of another set, referred to as the codomain. A new set of ordered pairs made up of elements from sets X and Y and x in X is known as a binary relation across these sets.

The variable Y as a function of X is represented by table number 4. Because for every value of X there is a different value of Y.

X                   Y

26               -26

-26              24

The combined estimated weight of the two whales is 945.7 Pounds.

The estimated weight of a blue whale = 3.46 × 105

Total estimated weight of a blue whale = 363.3 Pounds

Now, the estimated weight of a sea whale = 5.6 × 104

Total estimated weight of a sea whale = 582.4 Pounds

For finding the combined estimated weight of the two whales,

we will add the total estimated weight of both whales.

Here is how we will do it:

Total estimated weight of a blue whale + Total estimated weight of a sea whale

= 363.3 Pounds + 582.4 Pounds

Hence, 945.7 Pounds will the combined estimated weight of the two whales.

For the standard deviation, from the equation find the value of X₀ is 10.2

What is Standard Deviation ?

The standard deviation measures the degree of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean (also known as the expected value) of the set, whereas a high standard deviation indicates that the values are dispersed over a wider range.

Given

Z = 1.3

μ = 5 , σ = 0.4

Now for  X₀

Z =    X₀ -X / σ

1.3 =   X₀ - 5 / 0.4

X₀ = 10.2
