Step-by-step explanation:
here,
x1= -5. x2=4
y1= -22. y2=r
slope(m)=3
now we have,
m=(y2-y1)/(x2-x1)
or,3=(r-(-22))/(4-(-5))
or,3=(r+22)/(4+5)
or,3=(r+22)/9
or,27=r+22
or,r=27-22
or,r=5

Find the equation of the line. use exact numbers
Answer:
y = -2x + 5
Step-by-step explanation:
The slope is -2/1 and the y intercept is 5.
In the figure below, k || l and m || n. Find the values of x and y.
Answer:
y=36
Step-by-step explanation:
using that 63° angle there on the right, we know that the other angle for a 180° total is 117°.
Now we have to figure out y using that total of 117
(4y-27)=117
4y-27=117
4y=144
y=36
Now if we substitute y...
(4y-27)=117
(4(36)-27)=117
(144-27)=117
(117)=117

Share $112 in the ratio 10:18 PLZ HELP
Answer:
$40 and $72, see below :)
Step-by-step explanation:
One way we can do this is to add the total ratios and then divide that from 112.
10x + 18x = 28x = 112
28x = 112
x = 4
That means, for every ratio, you just have to multiply the amount by 4.
so for example, 10 is just 10 * 4 = 40
So, your answer would be you share the money into $40 and $72

Shaq runs once around the track in 8.07 minutes. Felicia runs once
around the track in 4.90 minutes less than Shaq. How long does it
take Felicia to run once around the track? HUH?! Please help!
Answer:
Felicia needs 3.17 minutes to run once around the track
Step-by-step explanation:
Subtraction
Shaq is known to run once around the track in 8.07 minutes. Felicia runs once around the track in 4.90 less than Shaq.
We don't know how long does it take Felicia to run once around the track, but we can find it by subtracting the time done by Shaq with the difference between their relative times.
Felicia takes 8.07 min - 4.90 min = 3.17 min.
Felicia needs 3.17 minutes to run once around the track
9. What is the slope of the equation below?
y=-5 x + 9
Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 5x + 9 ← is in slope- intercept form
with slope m = - 5

Answer:
[tex]\dfrac{31}{2}+\dfrac{27}{2}i[/tex]
Step-by-step explanation:
The given complex number is:
[tex]z=\dfrac{(2+3i)(4-7i)(1+i)}{(1^2-i^2)}[/tex]
Firstly we can solve (2+3i)(4-7i)(1+i)
= 2(8)+2(-7i)+4(3i)+3i(-7i²)× (1+i)
= (16-14i+12i-21i²i)× (1+i)
Since, i² = -1
= (16-14i+12i-21(-1)i)× (1+i)
= (16-14i+12i+21)× (1+i)
= (29-2i)(1+i)
= 31+27i
Denominator : (1-i²)
= (1-(-1))
= 2
[tex]\dfrac{(2+3i)(4-7i)(1+i)}{(1^2-i^2)}=\dfrac{31+27i}{2}\\\\=\dfrac{31}{2}+\dfrac{27}{2}i[/tex]
Hence, the correct answer is [tex]\dfrac{31}{2}+\dfrac{27}{2}i[/tex].

Please show all working
thanks
Answer:
a) (i) 1200
b) (ii) 3750
c) (i) [tex]\frac{3}{20}[/tex]
Step-by-step explanation:
a) Total number of students = 5000
Ratio of teachers to students = 6 : 25
i) Number of teachers = ?
By the given ratio, we can let the number of teachers = 6[tex]x[/tex]
and we can let the number of students = 25[tex]x[/tex]
[tex]25x = 5000\\\Rightarrow x = 200[/tex]
Therefore, number of teachers = 6 [tex]\times[/tex] 200 = 1200
b) A Quarter of the students own i-phone classic 20.
ii) Number of students who do not own an i-phone classic?
As per question statement,
Number of students who own i-phone classic 20 = [tex]\frac{1}{4}\times 5000[/tex] = 1250
Number of students who do not own i-phone classic 20 = 5000 - 1250 = 3750
c) Number of students who own samsung galaxy a80s = 60% of students who own i-phone classic 20 = [tex]\frac{60}{100}\times 1250[/tex] = 750
Fraction of students who own samsung galaxy a80s = Number of students having samsung a80s divided by total number of students
[tex]\dfrac{750}{5000} = \dfrac{3}{20}[/tex]
Alan bought 3 CDs that were each the same price. Including sales tax, he paid a total of $38.70. Each CD had a tax of $1.10. What was the price of each CD before tax?
Answer:
$11.80
Step-by-step explanation:
3*$1.10 = $3.30
price without tax,
= 38.70-3.30
= 35.40
Cost of each CD,
= 35.40/3
= 11.80
Answer:
11.80 dollars
Step-by-step explanation:
Well, first I would multiply 1.10 by 3 which is 3.30 then subtract 38.70 - 3.30 and get 35.40, and finally divide 35.40 by 3 to get 11.80

Answer:
A. The slope is [tex]\frac{3}{2}[/tex]
B. the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point.
Step-by-step explanation:
PART A: Slope
Given tangent line;
[tex]y = \frac{3x}{2} + \frac{9}{2}[/tex]
The slope of the tangent line is equal to the derivative of the function;
[tex]\frac{dy}{dx} =\frac{3}{2}[/tex]
the slope = [tex]\frac{3}{2}[/tex]
PART B: Correct statement that describe the slope of a tangent line:
A secant line is a straight line joining two points on a function and the slope of the function is equal to average rate of change of the function between the two points.
A tangent line is a straight line that touches a function at only one point, and the slope of the function is equal to the instantaneous rate of change of the function at that one point.
Thus, the correct statement is " the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point".

Substitution method?It is a method for finding the values of variable, by substituting the value of one variable to get the another.
How to solve a polynomial equation?To solve a polynomial equation, first write it in standard form. Once it is equal to zero, factor it and then set each variable factor equal to zero.
a). We have, an equation
[tex]y = x^{3}+x^{2} -6x[/tex]
so, at x = -3
[tex]y = -3^{3} +(-3)^{2} -6(-3)[/tex] = -27+9+18 = 0 (substitute x = -3 in the given equation)
at x = -1
y = [tex]-1^{3} +(-1)^{2} -6(-1) = -1+1+6 = 6[/tex]
Hence, 0 and 6 will we written the blank spaces of the given table.
b). We have an equation
[tex]x^{3} +x^{2}-6x = 0[/tex]
⇒ [tex]x(x^{2} +x-6)=0[/tex]
⇒ [tex]x (x^{2} +3x-2x-6)=0[/tex]
⇒ [tex]x(x(x+3)-2(x+3))=0[/tex]
⇒ [tex]x(x+3)(x-2)=0[/tex]
⇒ [tex]x = 0,-3 and 2[/tex]
Hence, 0, -3 and 2 are the solutions of the given equation.

how is per capita gross domestic product calculated "total market value of goods and services produced within a year divided by total population"?
Answer: See explanation
Step-by-step explanation:
You didn't really say what you want to know but let me explain.
The gross domestic product of an economy is the value of the goods and.d services that are being produced in such an economy. The gross domestic Product is used to know how well an economy is doing
Per capita gross domestic product (GDP) is a used to know the economic output of a particular country per person. It is calculated by dividing the GDP of such an economy by the population.
For example, let us say the GDP of a country is $800,000,000 and the population is 3,500,254. Therefore, the per capita GDP would be:
= $800,000,000 / 3,500,254
= $228.56 per person

In the notation "s(X) = ...," what does "s(x)" represent?
A.
The value of s(x) depends on the value of x, since s is a function of x.
B.
The value found when sis multiplied by the value x.
С.
There is not enough information to answer this question.
D.
The value of x depends on the value of s(x), since x is a function of s.
Answer: Choice A) The value of s(x) depends on the value of x, since s is a function of x.
The outer letter s tells us what the function's name is. It's the dependent variable and it might be handy to tie it to the y variable. The x is the independent variable. It changes freely without relying on what s happens to be.
Answer: A. The value of s(x) depends on the value of x, since s is a function of x.
Step-by-step explanation: s(x) is the output of the function when a given value of x is calculated according the operations in the function.
